| Abstract: | This paper studies the role of endogenous producer entry and product creation for monetary policy analysis and business cycle dynamics in a general equilibrium model with imperfect price adjustment. Optimal monetary policy stabilizes product prices, but lets the consumer price index vary to accommodate changes in the number of available products. The free entry condition links the price of equity (the value of products) with marginal cost and markups, and hence with inflation dynamics. No-arbitrage between bonds and equity links the expected return on shares, and thus the financing of product creation, with the return on bonds, affected by monetary policy via interest rate setting. This new channel of monetary policy transmission through asset prices restores the Taylor Principle in the presence of capital accumulation (in the form of new production lines) and forward-looking interest rate setting, unlike in models with traditional physical capital. We also study the implications of endogenous variety for the New Keynesian Phillips curve and business cycle dynamics more generally, and we document the effects of technology, deregulation, and monetary policy shocks, as well as the second moment properties of our model, by means of numerical examples. |

| Abstract: | We describe some of the main features of the recent vintage macroeconomic models used for monetary policy evaluation. We point to some of the key differences with respect to the earlier generation of macro models, and highlight the insights for policy that these new frameworks have to offer. Our discussion emphasizes two key aspects of the new models: the significant role of expectations of future policy actions in the monetary transmission mechanism, and the importance for the central bank of tracking of the flexible price equilibrium values of the natural levels of output and the real interest rate. We argue that both features have important implications for the conduct of monetary policy. |

| Abstract: | This paper argues that there is a nonzero inflation-unemployment tradeoff in the long-run due to frictional growth, a phenomenon that encapsulates the interplay of nominal staggering and money growth. The existence of a downward-sloping long-run Phillips curve suggests the development of a holistic framework that can jointly explain the evolution of inflation and unemployment. Hence, we estimate an interactive dynamics model for the US that includes wage-price setting and labour market equations. We then evaluate the inflation-unemployment tradeoff and assess the impact of productivity, money growth, budget deficit, and trade deficit on the unemployment and inflation trajectories during the nineties. |

| Abstract: | We examine global economic dynamics under learning in a New Keynesian model in which the interest-rate rule is subject to the zero lower bound. Under normal monetary and fiscal policy, the intended steady state is locally but not globally stable. Large pessimistic shocks to expectations can lead to deflationary spirals with falling prices and falling output. To avoid this outcome we recommend augmenting normal policies with aggressive monetary and fiscal policy that guarantee a lower bound on inflation. In contrast, policies geared toward ensuring an output lower bound are insufficient for avoiding deflationary spirals. |

| Abstract: | In this paper we present two examples where the presence of inflation persistence could influence the qualitative nature of monetary policy. In the first case the desirability of a monetary policy regime comes under question when extensive inflation persistence exists. In the second case the direction in which interest rates move following a cost push shock changes when inflation persistence becomes important. In both cases, inflation persistence is central to the process influencing policy. |

| Abstract: | We use a Bayesian time-varying parameters structural VAR with stochastic volatility for GDP deflator inflation, real GDP growth, a 3-month nominal rate, and the rate of growth of M4 to investigate the underlying causes of the Great Moderation in the United Kingdom. Our evidence points towards a dominant role played by shocks in fostering the more stable macroeconomic environment of the last two decades. Results from counterfactual simulations, in particular, show that (1) the Great Inflation was due, to a dominant extent, to large demand non-policy shocks, and to a lesser extent–especially in 1973 and 1979–to supply shocks; (2) imposing the 1970s’ monetary rule over the entire sample period would have made almost no difference in terms of inflation and output growth outcomes; and (3) mechanically ‘bringing the Monetary Policy Committee back in time’ would only have had a limited impact on the Great Inflation episode, at the cost of lower output growth. These results are quite striking in the light of the more traditional, narrative approach, which suggests that the monetary policy regime is an important factor in explaining the Great Moderation in the United Kingdom. We discuss one interpretation which could explain both sets of results, based on the ‘indeterminacy hypothesis’ advocated, for the United States, by Clarida, Gali, and Gertler (2000) and Lubik and Schorfheide (2004).

| Abstract: | A major criticism against staggered nominal contracts is that they give rise to the so called "persistency puzzle" - although they generate price inertia, they cannot account for the stylised fact of inflation persistence. It is thus commonly asserted that, in the context of the new Phillips curve (NPC), inflation is a jump variable. We argue that this "persistency puzzle" is highly misleading, relying on the exogeneity of the forcing variable (e.g. output gap, marginal costs, unemployment rate) and the assumption of a zero discount rate. We show that when the discount rate is positive in a general equilibrium setting (in which real variables not only affect inflation, but are also influenced by it), standard wage-price staggering models can generate both substantial inflation persistence and a nonzero inflation-unemployment tradeoff in the long-run. This is due to frictional growth, a phenomenon that captures the interplay of nominal staggering and permanent monetary changes. We also show that the cumulative amount of inflation undershooting is associated with a downward-sloping NPC in the long-run. |

| Abstract: | We analyse the likely effects of changes in the monetary and financial regimes of EMU countries on the dynamics of output and inflation. In particular, we evaluate the impact of the regime shift on the forecasting performance of reduced-form models. Data for both the pre-EMU and the EMU regimes are generated by a relatively standard open-economy-DSGE model with sticky prices and wages and restricted access to financial markets for some individuals. We find that the effects of the shift in the monetary regime on the processes followed by macroeconomic variables depend on the nature of the shocks hitting the economy. For plausible shocks distributions the reduction in the accuracy of VAR-based inflation forecasts is relatively large and significant. The effect of the regime shift on output forecasts seem rather more modest and statistically insignificant. The impact on ouput forecasting accuracy would be comparatively much larger if the new monetary union regime is accompanied by a moderate relaxation of constraints affecting financial market access. |

| Abstract: | Conjectures about inflation expectations are inextricably linked to our understanding of the relationship between the real and monetary sides of the economy; yet, direct empirical research on the matter has been scarce at best. This paper therefore examines the empirical properties of inflation expectations data constructed on the basis of both qualitative and quantitative surveys of consumers for a set of eight European countries. The rational perceptions hypothesis is tested and rejected by the data, a finding which in turn leads us to reject the rational expectations hypothesis and casts doubt on the New Keynesian Phillips Curve model. The popular alternative of using “rule-of-thumb” expectations in such models empirically is also found to be unrobust. Similarly, the conjecture by Akerlof et al. (2000) of a non-vertical long-run Phillips curve arising from the presence of “near-rational” expectations cannot be supported. The Mankiw and Reis (2002) Phillips curve based on the idea of “sticky information” succeeds in its intuition of a gradual adjustment of expectations, but its assumption of rational updating is challenged by the data in the context of the natural experiment provided by the UK's ERM disinflation. Instead, the adjustment mechanism for expectations appears to display largely adaptive characteristics. Finally, the paper provides some insights into the nature of the interaction between monetary policy and inflation expectations. |

| Abstract: | Models in which firms use rules of thumb or partial indexing in their price setting have become prominent in the recent monetary policy literature. The extent to which these firms adjust their prices to lagged inflation has been taken as fixed. We consider the implications of firms choosing the optimal degree of indexation so these simple pricing rules deliver prices as close as possible to those which would be chosen optimally. We find that the degree of indexation depends on the extent of persistence in the economy such that models with constant indexation are vulnerable to the Lucas critique. We also study the interactions between firms price setting and the macroeconomic environment finding that, for the models which appear most plausible on microeconomic grounds, the Nash equilibrium between firms and the policy maker is characterised by zero indexation and zero macroeconomic persistence. |

| Abstract: | We show that low trend inflation strongly affects the dynamics of a standard Neo-Keynesian model where monetary policy is described by a standard Taylor rule. Moreover, trend inflation enlarges the indeterminacy region in the parameter space, substantially altering the so-called Taylor principle. The main results hold for di¤erent types of Taylor rules, inertial policy rules and indexation schemes. The key message is that, whatever the set up, the literature on Taylor rules cannot disregard average inflation in both theoretical and empirical analysis. |

| Abstract: | The Beveridge curve depicts a negative relationship between unemployed workers and jobvacancies, a robust finding across countries. The position of the economy on the curve givesan idea as to the state of the labour market. The modern underlying theory is the search andmatching model, with workers and firms engaging in costly search leading to randommatching. The Beveridge curve depicts the steady state of the model, whereby inflows intounemployment are equal to the outflows from it, generated by matching. |

| Abstract: | The canonical new Keynesian Phillips Curve has become a standard component of models designed for monetary policy analysis. However, in the basic new Keynesian model, there is no unemployment, all variation in labor input occurs along the intensive hours margin, and the driving variable for inflation depends on workers’ marginal rates of substitution between leisure and consumption. In this paper, we incorporate a theory of unemployment into the new Keynesian theory of inflation and empirically test its implications for inflation dynamics. We show how a traditional Phillips curve linking inflation and unemployment can be derived and how the elasticity of inflation with respect to unemployment depends on structural characteristics of the labor market such as the matching technology that pairs vacancies with unemployed workers. We estimate on US data the Phillips curve generated by the model, and derive the implied marginal cost measure driving inflation dynamics. |

| Abstract: | In this paper, we show that strategic complementarities–such as firm-specific factors or quasikinked demand–have crucial implications for the design of monetary policy and for the welfare costs of output and inflation variability. Recent research has mainly used log-linear approximations to analyze the role of these mechanisms in amplifying the real effects of monetary shocks. In contrast, our analysis explicitly considers the nonlinear properties of these mechanisms that are relevant for characterizing the deterministic steady state as well as the second-order approximation of social welfare in the stochastic economy. We demonstrate that firm-specific factors and quasi-kinked demand curves yield markedly different implications for the welfare costs of steady-state inflation and inflation volatility, and we show that these considerations have dramatic consequences in assessing the relative price distortions associated with the Great Inflation of 1965-1979. |

| Abstract: | Estimating money demand functions for Russia following the 1998 crisis, we find a stable money demand relationship when augmented by a deterministic trend signifying falling velocity. As predicted by theory, higher income boosts demand for real rouble balances and the income elasticity of money is close to unity. Inflation affects the adjustment towards equilibrium, while broad money shocks lead to higher inflation. We also show that exchange rate fluctuations have a considerable influence on Russian money demand. The results indicate that Russian monetary authorities have been correct in using the money stock as an information variable and that the strong influence of exchange rate on money demand is likely to continue despite de-dollarisation of the Russian economy. |

| Abstract: | We develop a utility based model of fluctuations, with nominal rigidities, and unemployment. In doing so, we combine two strands of research: the New Key- nesian model with its focus on nominal rigidities, and the Diamond-Mortensen-Pissarides model, with its focus on labor market frictions and unemployment. In developing this model, we proceed in two steps. We first leave nominal rigidities aside. We show that, under a standard utility specification, productivity shocks have no effect on unemployment in the constrained effcient allocation. We then focus on the implications of alternative real wage setting mechanisms for fluctuations in unemployment. We then introduce nominal rigidities in the form of staggered price setting by firms. We derive the relation between inflation and unemployment and discuss how it is influenced by the presence of real wage rigidities. We show the nature of the tradeoff between inflation and unemployment stabilization, and we draw the implications for optimal monetary policy. |

| Abstract: | A widely spread belief among economists is that monetary policy has relatively short-lived effects on real variables such as unemployment. Previous studies indicate that monetary policy affects the output gap only at business cycle frequencies, but the effects on unemployment may well be more persistent in countries with highly regulated labor markets. We study the Swedish experience of unemployment and monetary policy. Using a structural VAR we find that around 30 percent of the fluctuations in unemployment are caused by shocks to monetary policy. The effects are also quite persistent. In the preferred model, almost 30 percent of the maximum effect of a shock still remains after ten years. |

| Abstract: | How can we explain the observed behavior of aggregate inflation in response to e.g. monetary policy changes? Mankiw and Reis (2002) have proposed sticky information as an alternative to Calvo sticky prices in order to model the conventional view that i) inflation reacts with delay and gradually to a monetary policy shock, ii) announced and credible disinflations are contractionary and iii) inflation accelerates with vigorous economic activity. I use a fully-fledged DSGE model with sticky information and compare it to Calvo sticky prices, allowing also for dynamic inflation indexation as in Christiano, Eichenbaum, and Evans (2005). I find that sticky information and sticky prices with dynamic inflation indexation do equally well in my DSGE model in delivering the conventional view. |

| Abstract: | The rational expectations equilibrium of a small open economy can be subject to indeterminacy if foreign monetary policy does not satisfy the Taylor principle. We study the implications of foreign-induced indeterminacy for the conduct of monetary policy in a small open economy. In the canonical sticky-price small open economy model, we find that indeterminacy arising in the large economy can increase the volatility of the small economy. Our main finding, however, is that ‘smallness’ is a property of the unique rational expectations equilibrium of the large economy, and not a general property of the small open economy model. If the <em>large</em> economy fails to anchor expectations, shocks to the small economy can affect the large one. This form of indeterminacy gives rise to a ‘butterfly effect’. Additional assumptions are required to preserve the ‘smallness’ of the small economy. |

| Abstract: | In this paper, I present a unified and micro-founded explanation for various types of inflation without assuming ad hoc frictions or irrationality. The explanation is similar to the conventional inflation theory in the sense that an independent central bank can control inflation and also similar to the fiscal theory of the price level in the sense that a source of inflation lies in the behavior of government. Inflation accelerates or decelerates through the simultaneous optimization of a government and the representative household if their time preference rates are heterogeneous. This inflation acceleration mechanism will be prevented from working if a central bank is truly independent. |

| Abstract: | The labor search and matching model plays a growing role in macroeconomic analysis. Thispaper provides a critical, selective survey of the literature. Four fundamental questions areexplored: how are unemployment, job vacancies, and employment determined as equilibriumphenomena? What determines worker flows and transition rates from one labor market stateto another? How are wages determined? What role do labor market dynamics play inexplaining business cycles and growth? The survey describes the basic model, reviews itstheoretical extensions, and discusses its empirical applications in macroeconomics. Themodel has developed against the background of difficulties with the use of the neoclassical,frictionless model of the labor market in macroeconomics. Its success includes the modellingof labor market outcomes as equilibrium phenomena, the reasonable fit of the data, and —when inserted into business cycle models — improved performance of more generalmacroeconomic models. At the same time, there is evidence against the Nash solution usedfor wage setting and an active debate as to the ability of the model to account for some of thecyclical facts. |

| Abstract: | The question how best to communicate monetary policy decisions remains a highly topical issue among central banks. Focusing on the experience of the European Central Bank, this paper studies how explanations of monetary policy decisions at press conferences are perceived by financial markets. The empirical findings show that ECB press conferences provide substantial additional information to financial markets beyond that contained in the monetary policy decisions, and that the information content is closely linked to the characteristics of the decisions. Press conferences indeed have on average had larger effects on financial markets than even the corresponding policy decisions, and with lower effects on volatility. Moreover, the Q&A part of the press conference fulfils a clarification role about the economic outlook, in particular during periods of large macroeconomic uncertainty.

| Abstract: | We examine the performance and robustness properties of monetary policy rules in an estimated macroeconomic model in which the economy undergoes structural change and where private agents and the central bank possess imperfect knowledge about the true structure of the economy. Policymakers follow an interest rate rule aiming to maintain price stability and to minimize fluctuations of unemployment around its natural rate but are uncertain about the economy’s natural rates of interest and unemployment and how private agents form expectations. In particular, we consider two models of expectations formation - rational expectations and learning. We show that in this environment the ability to stabilize the real side of the economy is significantly reduced relative to an economy under rational expectations with perfect knowledge. Furthermore, policies that would be optimal under perfect knowledge can perform very poorly if knowledge is imperfect. Efficient policies that take account of private learning and misperceptions of natural rates call for greater policy inertia, a more aggressive response to inflation, and a smaller response to the perceived unemployment gap than would be optimal if everyone had perfect knowledge of the economy. We show that such policies are quite robust to potential misspecification of private sector learning and the magnitude of variation in natural rates. JEL Classification: E52. |

| Abstract: | In this paper I analyse four different but related concepts, each of which highlights someaspect of the way in which the state acquires command over real resources through its ability to issue fiat money. They are (1) seigniorage (the change in the monetary base), (2) Central Bank revenue (the interest bill saved by the authorities on the outstanding stock of base money liabilities), (3) theinflation tax (the reduction in the real value of the stock of base money due to inflation and (4) the operating profits of the central bank, or the taxes paid by the Central Bank to the Treasury.To understand the relationship between these four concepts, an explicitly intertemporalapproach is required, which focuses on the present discounted value of the current and future resource transfers between the private sector and the state. Furthermore, when the Central Bank is operationally independent, it is essential to decompose the familiar consolidated 'government budget constraint' and consolidated 'government intertemporal budget constraint' into the separate accountsand budget constraints of the Central Bank and the Treasury. Only by doing this can we appreciate the financial constraints on the Central Bank's ability to pursue and achieve an inflation target, and theimportance of cooperation and coordination between the Treasury and the Central Bank when facedwith financial sector crises involving the need for long-term recapitalisation or when confronted with the need to mimic Milton Friedman's helicopter drop of money in an economy faced with a liquidity trap. |

| Abstract: | This paper focuses specifically on the recent Soludo’s banking sector reforms. The study noted that the Soludo’s reforms focused on strengthening the financial systems through banking sector consolidation, foreign exchange market stabilization, interest rates restructuring and the pursuit of stabilization as against structural adjustment policies for monetary and inflationary controls. A review of theoretical qualifications to the Soludo’s reform show that in thoughts, it is rooted in the Classical traditions of Say’s Law, acts monetarist, but expects a Keynesian outcome that money can stimulate expansion in aggregate domestic output. In concluding, the study noted the need to adopt an interest rate operating procedures for monetary policy in addition to moving the economy consciously towards the ‘law of one market and one price’ for the domestic and foreign money markets. |

| Abstract: | The paper reconsiders the role of money and banking in monetary policy analysis by including a banking sector and money in an optimizing model otherwise of a standard type. The model is implemented quantitatively, with a calibration based on U.S. data. It is reasonably successful in providing an endogenous explanation for substantial steady-state differentials between the interbank policy rate and (i) the collateralized loan rate, (ii) the uncollateralized loan rate, (iii) the T-bill rate, (iv) the net marginal product of capital, and (v) a pure intertemporal rate. We find a differential of over 3 % pa between (iii) and (iv), thereby contributing to resolution of the equity premium puzzle. Dynamic impulse response functions imply pro-or-counter-cyclical movements in an external finance premium that can be of quantitative significance. In addition, they suggest that a central bank that fails to recognize the distinction between interbank and other short rates could miss its appropriate settings by as much as 4% pa. Also, shocks to banking productivity or collateral effectiveness call for large responses in the policy rate. |

| Abstract: | This paper shows that ination in industrialized countries is largely a global phenom- enon. First, inations of (22) OECD countries have a common factor that alone accounts for nearly 70% of their variance. This large variance share that is associated to Global Ination is not only due to the trend components of ination (up from 1960 to 1980 and down thereafter) but also to uctuations at business cycle frequencies. Second, Global In- ation is, consistently with standard models of ination, a function of real developments at short horizons and monetary developments at longer horizons. Third, there is a very robust "error correction mechanism" that brings national ination rates back to Global Ination. This model consistently beats the previous benchmarks used to forecast ination 1 to 8 quarters ahead across samples and countries. |

| Abstract: | This paper seeks to demonstrate that a backward looking specification of the IS curve using UK data can encompass the forward looking model recently discussed by Kara and Nelson (2004). By relaxing the restriction that the interest rate and the inflation rate enter the IS curve with coefficients of equal magnitude but opposite sign, we obtain IS curve estimates which are empirically plausible and which encompass the rival specification. |

| Abstract: | The standard derivation of a Phillips curve from a DSGE model requires that all variables are measured as deviations from their steady states. But in practice this is not done. The steady state for output is estimated by some statistical procedure, such as the HP filter, and the steady state for other variables, including inflation, is treated as a constant. This is inconsistent with the theory and raises econometric problems since inflation, for instance, is a very persistent series. We argue that the natural definition of the steady state is the long-horizon forecast and estimate these permanent components from a cointegrating VAR that takes account of global interactions. This estimate of the steady state will reflect any long-run theoretical relationships embodied in the cointegrating vectors. We then estimate Phillips Curves and other standard monetary transmission equations using deviations from the steady states on US data. This is both consistent with the theory and uses the relevant economic information about steady states. |

| Abstract: | This paper takes a first step in analysing how a monetary union performs in the presence of labour market asymmetries. Differences in wage flexibility, market power and country sizes are allowed for in a setting with both country-specific and aggregate shocks. The implications of asymmetries for both the overall performance of the monetary union and the country-specific situation are analysed. It is shown that asymmetries can have important effects, and that there are substantial spill-over effects. Among other things, it is found that aggregate output volatility is not strictly increasing in nominal rigidity but hump-shaped. A disproportionate share of the consequences of wage inflexibility may fall on small countries. In the case of country-specific shocks a country unambiguously benefits in terms of macroeconomic stability by becoming more flexible, but in general an inflexible country does not necessarily achieve more output stability by becoming more flexible. As this may be desirable for the monetary union as a whole, there is a risk of a ’reform deficit’ in an asymmetric monetary union. |

| Abstract: | In this paper we introduce and test the hypothesis that the relation between inflation and unemployment has been in many countries subject to a significant change in the early 1990's after the disinflation period. That period began between 1975 and 1980 after the first (or the second) oil price shock in autumn 1973. During the disin°ation period, inflation and unemployment were the result of the struggle between the wage and price setters trying to influence the distribution of income to their favour and the Central Bank fighting against inflation. Since the wage and price setters did not fully believe in an \unconditional" pursuit of the anti-inflationary policy, the result was a gradual decline of the inflation rate rendered possible by a rising rate of unemployment. Our hypothesis was inspired by the observation that the statistical Phillips curves are now rather flat in many countries. If such horizontal Phillips curves will also result when they are estimated taking into account the most important other factors influencing the inflation rate (mainly supply shocks) they may be explained by the hypothesis that during the 1990's, wage and price setters finally accepted the new rigour of the monetary policy and tried no more (nor had the market power { due to increasing globalisation and international competition) to pursue a policy which raises the inflation rate significantly above the target inflation rate of the Central Bank. In that case a "break" in the parameters of the Phillips-Curve should be observed. We use econometric methods to test whether the presumed \break" in the re- lation between inflation and unemployment can be shown to exist. We restrict our study to the four largest countries of the Euro area (Germany, France, Italy and Spain), the UK and the USA. The result are very di®erent for the countries; therefore we intend in a further step to detect the reasons for there divergences. |

| Abstract: | We use the Factor-Augmented Vector Autoregression (FAVAR) approach of Bernanke, Boivin and Eliasz (2005) to estimate the effects of monetary policy shocks on wages and employment in the euro area. The use of a large data set comprising country, sectoral and euro area-wide data allows us to better identify common monetary policy shocks in the euro area and their effects on labour market outcomes. At the same time the FAVAR approach gives us estimates of how relative wages and employment in the various countries and sectors respond to these common shocks. The ultimate objective of our work is to relate the estimated cross-country differences in wage and employment responses to differences in labour market institutions and sectoral composition. |

| Abstract: | Inflation and unemployment are central issues in macroeconomics. While progress has been made on these issues recently using models that explicitly incorporate search-type frictions, existing models analyze either unemployment or inflation in isolation. We develop a framework to analyze unemployment and inflation together. This makes contributions to disparate literatures, and provides a unified model for theory, policy, and quantitative analysis. We discuss optimal fiscal and monetary policy. We calibrate the model, and discuss the extent to which it can account for salient aspects of a half century’s experience with inflation, unemployment, interest rates, and velocity. Depending on some details concerning how one calibrations certain parameters, the model can do a good job matching the data. |

| Abstract: | We estimate the approximate nonlinear solution of a small DSGE model on euro area data, using the conditional particle filter to compute the model likelihood. Our results are consistent with previous findings, based on simulated data, suggesting that this approach delivers sharper inference compared to the estimation of the linearised model. We also show that the nonlinear model can account for richer economic dynamics: the impulse responses to structural shocks vary depending on initial conditions selected within our estimation sample. |

| Abstract: | Over the past forty years, U.S. inflation has exhibited highly persistent movements. Moreover, these shifts in inflation have typically had real consequences, implying a "sacrifice ratio," whereby disinflations are typically associated with recessions and persistent increases in inflation often associated with booms. One hypothesis about the source of the sacrifice ratio is that inflation - and not just the price level - is sticky. Another is that private-sector agents typically must infer changes in inflation objectives indirectly from central bank interest- rate policy. The resulting learning process can lead to a sacrifice ratio trade-off. In this paper, I allow for both sticky inflation and learning in interpreting U.S. macroeconomic developments since 1955. Two key empirical findings are, first, that allowing for learning reduces the evidence for sticky inflation. Second, there is less evidence for sticky inflation in the post-1983 period than earlier. Indeed, in some estimates, there is little evidence of sticky inflation in the period since 1983, although this result is sensitive to the details of the specification. Nonetheless, simulation results suggest that for realistic models, the sacrifice ratio can be accounted for entirely by learning. |

| Abstract: | In a micro-founded framework in line with the new open economy macroeconomics, the paper shows that more centralized wage setting (CWS) and central bank conservatism (CBC) curb unemployment only if labor market distortions are sizeable. When labor market distortions are sufficiently low, employment may be maximized by atomistic wage setters or a populist CB. The comparison between a national monetary policy (NMP) regime and the monetary union (MU) reveals that a move to a MU boosts inflation in the absence of strategic effects. However, when strategic interactions between CB(s) and trade unions are taken into account, the shift to a MU when monopoly distortions are sizeable unambiguously increases welfare and employment either in presence of a sufficiently conservative CB or with a fully CWS. Finally, when labor market distortions are less relevant, an ultra-populist CB or atomistic wage setters are optimal for the society and a shift to a MU regime is unambiguously welfare improving. |

| Abstract: | This paper reviews the analytics of the effects of globalization on the Phillips curve and the utility-based objective function of the central bank. It demonstrates that in an endogenous-policy set up, when trade in goods is liberalized, financial openness increases, and in- and out-labor migration are allowed, policymakers become more aggressive on inflation and less responsive to the output gap. In other words, globalization induces the monetary authority, when guided in its policy by the welfare criterion of a representative household, to put more emphasis on the reduction of inflation variability, at the expense of an increase in the output gap variability. |

| Abstract: | We assess the quantitative importance of expectation effects of regime shifts in monetary policy in a DSGE model that allows the monetary policy rule to switch between a “bad” regime and a ”good” regime. When agents take into account such regime shifts in forming expectations, the expectation effect is asymmetric. In the good regime, the expectation effect is small despite agents’ disbelief that the regime will last forever. In the bad regime, however, the expectation effect on equilibrium dynamics of inflation and output is quantitatively important, even if agents put a small probability that monetary policy will switch to the good regime. Although the expectation effect dampens aggregate fluctuations in the bad regime, a switch from the bad regime to the good regime can still substantially reduce the volatility of both inflation and output, provided that we allow some “reduced-form” parameters in the private sector to change with monetary policy regime. |

| Abstract: | This paper introduces new data on the term in office of central bank governors in 137 countries for 1970-2004. Our panel models show that the probability that a central bank governor is replaced in a particular year is positively related to the share of the term in office elapsed, political and regime instability, the occurrence of elections, and inflation. The latter result suggests that the turnover rate of central bank governors (TOR) is a poor indicator of central bank independence. This is confirmed in models for cross-section inflation in which TOR becomes insignificant once its endogeneity is taken into account. |

Consequently, some observations are censored and cause bias in conventional estimators of typical Taylor rules. To account for the censored and discrete process of policy rate setting, I devise a new method for monetary policy rule estimation and demonstrate its ability to outperform the existing conventional estimators using two examples.

| Abstract: | This paper examines the evolution of the Phillips Curve (PC) for the Spanish economy since 1980. In particular, we focus on what has happened since the late 1990s. Since 1999 the unemployment rate has fallen by almost 7 percentage points, while inflation has remained relatively subdued around a plateau of 2%- 4%. Thus, the slope of the PC has become much flatter. We argue that this favorable evolution is largely due to the huge rise in the immigration rate, from 1% of the population in 1994 to 9.3% in 2006. We derive a New Keynesian Phillips curve accounting for the e¤ects of immigration, a variable which is found to shift the curve if preferences and bargaining power of immigrants and natives di¤er. We then estimate this curve for Spain since 1980 and find that while the fall in unemployment over the last 8 years comes along with an increase in inflation of 2.2 percentage points per year, the increase of the relative unemployment rate of immigrants vis-à-vis natives accounts for an ofsetting 0.9 percentage points drop in the inflation rate per year. |

| Abstract: | The New Keynesian Phillips curve (NKPC) has become the dominant model on inflation dynamics. Moreover, a large body of empirical research has documented in recent years price-setting behaviour at the individual level, which allows the assessment of the microfoundations of pricing models. It is found that a generalised version of the hybrid NKPC of Gali and Gertler (1999) accounts for a number of stylised facts, including rule of thumb price setters, and inflation persistence. Other frequently used versions of the NKPC, such as those that consider full or partial indexation or costs of adjustment, are clearly at odds with micro price evidence. |

| Abstract: | We examine the linear-quadratic (LQ) approximation of non-linear stochastic dynamic optimization problems in macroeconomics, in particular for monetary policy. We make four main contributions: first, we draw attention to a general Hamiltonian framework for LQ approximation due toMagill (1977). We show that the procedure for the ‘large distortions’ case of Benigno and Woodford (2003, 2005) is equivalent to the Hamiltonian approach, but the latter is far easier to implement. Second, we apply the Hamiltonian approach to a Dynamic Stochastic General Equilibrium model with external habit in consumption. Third, we introduce the concept of target-implementability which fits in with the general notion of targeting rules proposed by Svensson (2003, 2005). We derive sufficient conditions for the LQ approximation to have this property in the vicinity of a zero-inflation steady state. Finally, we extend the Hamiltonian approach to a non-cooperative equilibrium in a two-country model. JEL Classification: E52, E37, E58. |

| Abstract: | OBJECTIVES AND MOTIVATION: This paper considers the impact of interactions between competitiveness, fiscal policy and monetary institutions in the presence of unionized labor markets on economic outcomes and welfare in the long run. Two main classes of questions are investigated. First, what is the impact of exogenously given labor taxes and unemployment benefits on the choice of monetary policy by the central bank, on the choice of nominal wages by unions, on the choice of prices by monopolistically competitive firms and through them on unemployment, inflation and welfare? A related question is, how does the level of competitiveness on goods’ market affect the economy and welfare? Second, how are labor taxes and redistribution chosen by a (Stackelberg leader) fiscal authority whose objectives are a weighted average of social welfare and of catering to the interests of political supporters, and how does the general equilibrium induced by this choice affect welfare? The framework of the paper is motivated by the European scene in which the fraction of the labor force covered by collective agreements dominates wage setting in the labor market. “PLAYERS” AND PAYOFFS: The model economy features labor unions that maximize the expected real income of union members over states of employment and of unemployment, a central bank that strives to minimize the combined costs of inflation and of unemployment, and a continuum of monopolistically competitive firms, each of which maximizes its profits. The last part of the paper also features a fiscal authority that sets taxes and redistribution so as to maximize a combination of social welfare and of benefits to particular constituencies. Utility from consumption is characterized by means of a CES, Dixit-Stiglitz, utility function and (as in Sidrauski type models) money appears in the utility function. METHODOLOGY AND “PLAYERS” STRATEGIES: The first question is investigated within a three stage game in which labor unions move first and commit to nominal wages and the central bank moves second and chooses the money supply. In the third and last stage each of a large number of monopolistically competitive firms picks its price. To deal with the second class of questions the game is expanded to feature a preliminary stage in which government chooses labor taxes and redistribution anticipating the subsequent responses of the other players. General equilibrium is characterized and used to find the impact of various economic and institutional parameters. |

| Abstract: | How do financial frictions affect the response of an economy to aggregate shocks? In this paper, we address this question, focusing on liquidity constraints and uninsurable idiosyncratic risk. We consider a search model where agents use liquid assets to smooth individual income shocks. We show that the response of this economy to aggregate shocks depends on the rate of return on liquid assets. In economies where liquid assets pay a low return, agents hold smaller liquid reserves and the response of the economy tends to be larger. In this case, agents expect to be liquidity constrained and, due to a self-insurance motive, their consumption decisions are more sensitive to changes in expected income. On the other hand, in economies where liquid assets pay a large return, agents hold larger reserves and their consumption decisions are more insulated from income uncertainty. Therefore, aggregate shocks tend to have larger effects if liquid assets pay a lower rate of return. |

| Abstract: | OECD unemployment rates show long swings which dominate shorter business cycle components and these long swings show a range of common patterns. Using a panel of 21 OECD countries 1960-2002, we estimate the common factor that drives unemployment by the first principal component. This factor has a natural interpretation as a measure of global expected returns, which is given added plausibility by the fact that it is almost identical to the common factor driving investment shares. We estimate a model of unemployment adjustment, which allows for the influence both of the global factor and of labour market institutions and we examine whether the global factor can act as a proxy for the natural rate in a Phillips Curve. In 15 out of the 21 countries one cannot reject that the same natural rate, as a function of the global factor, appears in both the unemployment and inflation equations. In explaining both unemployment and inflation, the global factor is highly significant, suggesting that models which ignore the global dimension are likely to be deficient. |

| Abstract: | This paper presents the update of the macroeconometric model used at the Bank of Spain for medium term macroeconomic forecasting, as well as for performing policy simulations. The many changes that the Spanish economy has experimented in the last years, and the new system of national accounts published by the national statistical office, suggested that a reestimation of the model was due. This paper presents such reestimation with newer data (up to the end of 2005), and includes some modifications that were deemed necessary in certain equations. The quarterly model of the Bank of Spain keeps a similar structure to its previous version; it still is basically a demand-driven model. It is found that the Spanish economy shows, in general, higher sensitivity than in previous periods to changes in exogenous variables, especially in financial conditions. The new model reflects, too, changes in demographic trends, and presents an external sector less sentitive to changes in price-competitiveness. |

| Abstract: | We assess the empirical relevance for inflation dynamics of accounting for the presence of search frictions in the labor market. The New Keynesian Phillips curve explains inflation dynamics as being mainly driven by current and expected future marginal costs. Recent empirical research has emphasized different measures of real marginal costs to be consistent with observed inflation persistence. We argue that, allowing for search frictions in the labor market, real marginal cost should also incorporate the cost of generating and maintaining long-term employment relationships, along with conventional measures, such as real unit labor costs. In order to construct a synthetic measure of real marginal costs, we use newly available labor market data on worker finding and separation rates that reflect firing and hiring costs to the firm. We then estimate a New Keynesian Phillips curve using structural econometric techniques. |

We show that despite the strong similarities between the two assumptions to a first order of approximation, in general they might entail different welfare costs at higher order of approximation. In the special case of non-distorted steady state, the two pricing assumptions imply identical welfare losses to a second order of approximation. JEL Classification: E3, E5. |

| Abstract: | In an overlapping generations maximization framework with consumers, whose information on uncertain future income realizations is front-loaded, a closed form aggregate consumption function with CRRA preferences is derived. To have a closed form solution we assume that consumers solve their intertemporal optimization problem sequentially. First they assess riskadjusted life-time wealth and then the optimal consumption path. The derived model captures precautionary saving, which is dependent on the human to non-human wealth ratio. On aggregate level, after accounting for habit formation, the model is able to explain both the short-run (e.g. the excess sensitivity and the excess smoothness puzzle) and long-run stylized facts of the U.S. consumption data.

| Abstract: | This paper provides new insight into the relationship between inflation and consumer price setting by examining a large data set of Mexican consumer prices covering episodes of both low and high inflation, as well as the transition between the two. Overall, the economy shares several characteristics with time-dependent models when the annual inflation rate is low (below 10-15%), while displaying strong state dependence when inflation is high (above 10-15%). At low inflation levels, the aggregate frequency of price changes responds little to movements in inflation because movements in the frequency of price decreases partly offset movements in the frequency of price increases. When the annual inflation rate rises beyond 10-15 percent, however, there are no longer enough price decreases to counterbalance the rising occurrence of price increases, making the frequency of price changes more responsive to inflation. It is shown that a simple menu-cost model with idiosyncratic technology shocks predicts remarkably well the level of the average frequency and magnitude of price changes over a wide range of inflation. |

| Abstract: | A neoclassical growth model is augmented by a corporate sector, financial intermediation, and a set of tax rates. In this setting, capital structure is determined by the interplay between an advantage of debt finance resulting from the tax system and a disadvantage resulting from asymmetric information and the entailed agency costs. Effects of capital tax reforms are investigated with a special focus on the credit channel that operates through the finance decision of firms. The theoretical part of the article derives which financial and real effects of private and corporate income tax policies can be expected. Using a calibration with U.S.\ data, the applied part demonstrates that tax cuts cause significant adjustments of capital structure. Nevertheless, the credit channel creates relatively small effects of tax reforms on consumption, investment, and growth. |

| Abstract: | Analyzing a large weekly retail transaction price dataset, we uncover a surprising regularity— small price increases occur more frequently than small price decreases for price changes of up to about 10 cents, while there is no such asymmetry for larger price changes. The asymmetry holds for the entire sample and for individual categories. We find that while inflation can explain some of the asymmetry, inflation is not the whole story as the asymmetry holds even after excluding inflationary periods from the data, and even for products whose price had not increased over the eight-year period. The findings hold for different measures of inflation and also after allowing for lagged price adjustments. We offer a consumer-based explanation for these findings. |

| Abstract: | Temporal distribution of individual price changes is of crucial importance for business cycle theory and for the micro-foundations of price adjustment. While it is routinely assumed that price changes are staggered over time, both theory and evidence are ambiguous. We use a large Belgian data set to analyze whether price changes are staggered or synchronized. We find that the more aggregate the data, the closer the distribution to perfect staggering. This result holds for both aggregation across goods and across locations. Our results provide support for Bhaskar’s (2002) model of synchronized adjustment within, and staggered adjustment across, industries. |

| Abstract: | It is clear that at present various versions of the Calvo (1983) model of price adjustment are dominant in monetary policy analysis—see, e.g., Woodford (2003). This is true despite well-known criticisms including Mankiw (2001) or Mankiw and Reis (2002) and the well-documented need for the addition of ad-hoc features if actual inflation and output data are to be matched. Accordingly, there is ample reason, to give consideration to alternative models. In this paper, a new look is given to the P-bar model utilized by McCallum and Nelson (1999a, 1999b), based on previous work by Mussa (1981) and others. Relative to the Calvo model, the P-bar specification has three significant advantages: it satisfies the strict version of the natural rate hypothesis; it relies on costs of adjusting output, which are more tangible than menu costs of changing prices; and its basic version produces more realistic autocorrelation patterns than does the basic Calvo specification. The present paper develops these comparisons more completely and systematically than in previous work. |

| Abstract: | The US has experienced a sustained increase in productivity growth since the mid-1990s, particularly in sectorsthat intensively use information technologies (IT). This has not occurred in Europe. If the US "productivitymiracle" is due to a natural advantage of being located in the US then we would not expect to see any evidenceof it for US establishments located abroad. This paper shows in fact that US multinationals operating in the UKdo have higher productivity than non-US multinationals in the UK, and this is primarily due to the higherproductivity of their IT. Furthermore, establishments that are taken over by US multinationals increase theproductivity of their IT, whereas observationally identical establishments taken over by non-US multinationalsdo not. One explanation for these patterns is that US firms are organized in a way that allows them to use newtechnologies more efficiently. A model of endogenously chosen organizational form and IT is developed toexplain these new micro and macro findings. |

| Abstract: | We consider the effect of excluding government investment from the deficit subject to the limits of the European Stability and Growth Pact. In the model we consider, residents of a given country discount future costs and benefits of government spending more than efficiency would dictate, because they fail to take into account the portion that will accrue to people that have not yet been born or immigrated into the country. It is thus in principle desirable to design budget rules that favor long-term investment (by allowing more borrowing) over other government spending that only carries short-term benefits. However, given the low rates of population growth, mortality, and mobility across European countries, we find that the distortions arising from treating all government spending equally are likely to be modest. We also show that these modest distortions can be alleviated only if net government investment is excluded from the deficit computation; excluding gross investment may even be counterproductive, as it promotes overspending in government capital. |

| Abstract: | We analyze the effects of neutral and investment-specific technology shocks on hours worked and unemployment. We characterize the response of unemployment in terms of job separation and job finding rates. We find that job separation rates mainly account for the impact response of unemployment while job finding rates for movements along its adjustment path. Neutral shocks increase unemployment and explain a substantial portion of unemployment and output volatility; investment-specific shocks expand employment and hours worked and mostly contribute to hours worked volatility. We show that this evidence is consistent with the view that neutral technological progress prompts Schumpeterian creative destruction, while investment specific technological progress has standard neoclassical features. |

| Abstract: | This paper examines fungibility as a possible explanation for the "missing link" between foreign aid and economic growth. The composition of aid plays a crucial role in determining the composition of government spending and, consequently, the magnitude of fungibility and its impact on growth. Embedding fungibility as an equilibrium outcome in an endogenous growth framework, we show that the substitution away from domestic government investment is higher than from government consumption. This leads to a reduction in domestic productive public spending and completely offsets any positive impact that aid might have on growth. The main predictions of the model are tested using a panel dataset of 67 countries for 1972-2000. We find strong evidence of fungibility at the aggregate level: almost 70 percent of total aid is fungible in our sample. We also find that investment aid is more fungible than other categories of aid. In the presence of fungibility, there is no statistically significant relationship between foreign aid and economic growth. |

| Abstract: | This paper estimates a common component in many price series that has an equiproportional effect on all prices. Changes in this component can be interpreted as changes in the value of the numeraire since, by definition, they leave all relative prices unchanged. The first aim of the paper is to measure these changes. The paper provides a framework for identifying this component, suggests an estimator for the component based on a dynamic factor model, and assesses its performance relative to alternative estimators. Using 187 U.S. time-series on prices, we estimate changes in the value of the numeraire from 1960 to 2006, and further decompose these changes into a part that is related to relative price movements and a residual ‘exogenous’ part. The second aim of the paper is to use these estimates to investigate two economic questions. First, we show that the size of exogenous changes in the value of the numeraire helps distinguish between different theories of pricing, and that the U.S. evidence argues against several strict theories of nominal rigidities. Second, we find that changes in the value of the numeraire are significantly related to changes in real quantities, and discuss interpretations of this apparent non-neutrality. |

| Abstract: | Firms adjust labor both at the intensive and at the extensive margin (see, e.g., Hansen and Sargent 1988). Moreover, employment adjustment is not frictionless (see, e.g., Mortensen and Pissarides 1994). What does this imply for inflation dynamics? To address this question we develop a New Keynesian model featuring two margins of labor adjustment as well as a simultaneous price-setting and employment decision at the firm level. We find that the presence of an empirically plausible labor adjustment decision at the firm level rationalizes strategic complementarities in price-setting which help explain in‡ation dynamics. |

| Abstract: | This paper reviews the perspective of banking sector reforms since 1970 to date. It notes four eras of banking sector reforms in Nigeria, viz.: Pre-SAP (1970-85), the Post-SAP (1986-93), the Reforms Lethargy (1993-1998), Pre-Soludo (1999-2004) and Post-Soludo (2005-2006). Using both descriptive statistics and econometric methods, three sets of hypothesis were tested: firstly that each phase of reforms culminated in improved incentives; secondly that policy reforms which results in increased capitalization, exchange rate devaluation; interest rate restructuring and abolition of credit rationing may have had positive effects on real sector credit and thirdly that implicit incentives which accompany the reforms had salutary macroeconomic effects. The empirical results confirm that eras of pursuits of market reforms were characterized by improved incentives. However, these did not translate to increased credit purvey to the real sector. Also while growth was stifled in eras of control, the reforms era was associated with rise in inflationary pressures. Among the pitfalls of reforms identified by the study are faulty premise and wrong sequencing of reforms and a host of conflicts emanating from adopted theoretical models for reforms and above all, frequent reversals and/or non-sustainability of reforms. In concluding, the study notes the need to bolster reforms through the deliberate adoption of policies that would ensure convergence of domestic and international rates of return on financial markets investments. |

| Abstract: | Most people accept that structural and labour market reforms are needed in Europe. However few have been undertaken. The usual conjecture is that reforms are costly in economic performance and costly to finance. Blanchard and Giavazzi (2003) and Spector (2004) develop a general equilibrium model with imperfect competition to show the impact of labour or product market deregulation. We extend that model to combine both reforms, and include the costs of financing them, the conflict between long run gains and short run costs, and to allow for reforms of distortionary taxation. We also extend the model to explain the natural rate of unemployment and non-wage employment costs, to show the impact of reform on the short and long run Phillips curve parameters. We find that structural reforms imply short run costs but long run gains (unemployment rises and then falls, while wages move in the opposite way); that the long run gains outweigh the short run costs; and that the financing of such reforms is the main stumbling block. We also find that the implications for welfare improvements and employment generation are quite different: tax reforms are more effective for welfare, but market liberalisation for employment. |

| Abstract: | Credit market imperfections provide the key to understanding many important issues in business cycles, growth and development, and international economics. Recent progress in these areas, however, has left in its wake a bewildering array of individual models with seemingly conflicting results. This paper offers a road map. Using the same single model of credit market imperfections throughout, it brings together a diverse set of results within a unified framework. In so doing, it aims to draw a coherent picture so that one is able to see some close connections between these results, thereby showing how a wide range of aggregate phenomena may be attributed to the common cause. They include, among other things, endogenous investment-specific technical changes, development traps, leapfrogging, persistent recessions, recurring boom-and-bust cycles, reverse international capital flows, the rise and fall of inequality across nations, and the patterns of international trade. The framework is also used to investigate some equilibrium and distributional impacts of improving the efficiency of credit markets. One recurring finding is that the properties of equilibrium often respond non-monotonically to parameter changes, which suggests some cautions for studying aggregate implications of credit market imperfections within a narrow class or a particular family of models. |

| Abstract: | This paper re-examines the validity of the Phillips-Curve framework using US data. We make three main innovations. First, we introduce into the well-known Calvo price staggering framework, a regime-dependent price-changing signal. This means that a state-dependent linearization is no longer required to derive the Phillips relationship and thus that questions of regime dependency can be addressed. Second, we engage on a careful modeling of long-run supply in the economy, which permits more data-coherent measures of output gaps and real marginal costs indicators consistent with underlying, frictionless supply. Finally, we include two types of labor adjustment costs reflecting the intensive and extensive participation decisions. As regards the latter, we introduce the concept of “effective” working hours into the production technology which generates an overtime function directly into the mark-up equation. This, it turns, out has first-order implications for the cyclicality and econometric fit of the mark-up implied by the Phillips-curve representation. |

| Abstract: | The recently developed long-run risks asset pricing model shows that concerns about long-run expected growth and time-varying uncertainty (i.e., volatility) about future economic prospects drive asset prices. These two channels of economic risks can account for the risk premia and asset price fluctuations. In addition, the model can empirically account for the cross-sectional differences in asset returns. Hence, the long-run risks model provides a coherent and systematic framework for analyzing financial markets. |

| Abstract: | In the academic literature some criteria have been identified which could have an impact on the success of the transition process, such as macroeconomic stability, microeconomic restructuring and implementation of legal and institutional reforms. The role of the exchange rate system in general is to foster the stability of the monetary environment characterized by low inflation rates and a stable domestic currency. Although the importance of a sustainable price-level oriented monetary policy for the transition-success has been stressed in the academic literature, there are still further questions to be answered related to the choice of the exchange rate system throughout the different phases of the transition process. This paper intends to contribute to close this gap in the literature. The guiding research question is how the choice of an exchange rate system influences the economic success of a country in transition and its gradual integration within the European Union (EU) and the European Monetary Union (EMU). For this purpose, the study focuses on the transition process of South-eastern Europe (SEE). In particular and for the first time in a joint study, we will take a look at the following South-eastern European Countries (SEECs), often referred to as the “West Balkans”: Bosnia and Herzegovina (BiH), Croatia, Former Yugoslav Republic of Macedonia (FYRM), Serbia and Montenegro, as these five countries share certain common characteristics: they were part of the Former Yugoslav Republic (FYR); they are countries in transition; they are members of the Stability Pact for South-eastern Europe and they are all potential EU-accession candidates. |

| Abstract: | How inflation and unemployment are related in both the short run and long run is perhaps the key question in macroeconomics. This paper tests various price equations using quarterly U.S. data from 1952 to the present. Issues treated are the following. 1) Estimating price and wage equations in which wages affect prices and vice versa versus estimating "reduced form" price equations with no wage explanatory variables. 2) Estimating price equations in (log) level terms, rst difference (i.e., inflation) terms, and second difference (i.e., change in inflation) terms. 3) The treatment of expectations. 4) The choice and functional form of the demand variable. 5) The choice of the cost-shock variable. The results reject the use of rational expectations and suggest that the best speci cation is a price equation in level terms imbedded in a price-wage model, where the wage equation is also in level terms. The best cost-shock variable is the import price deflator, and the best demand variable is the unemployment rate. There is some evidence of a nonlinear effect of the unemployment rate on the price level at low values of the unemployment rate. Many of the results in this paper are contrary to common views in the literature, but the empirical support for them is strong. |

| Abstract: | This paper shows that adjustment costs modelled as firing costs of moderate size go a long way in explaining the variability and counter- cyclicality of the labour share at the firm and aggregate level. Firing costs cause firms to fire less in recessions and hire less in booms causing wage costs to fluctuate less cyclically than output, thus inducing variability and countercyclicality in the labour share. The paper develops a dynamic labour demand model with firing costs. The model is then calibrated using moments derived from 1634 French manufacturing firms and aggregate French manufacturing data. The calibrated model is able to closely match the variability and counter-cyclicality of the labour share at the firm level while it also generates a countercyclical aggregate labour share with a variability 60 % of that in French aggregate manufacturing.

| Abstract: | This paper builds upon Hoon and Phelps (1992, 1997) to ask how much of the evolution of the unemployment rate over several decades in country can be explained by real factors in an equilibrium model of the natural rate where country's productivity growth depends upon its distance from the world's technological leader. One motivating contemporary example includes the evolution of unemployment rates in Europe as it recovered from the second world war and caught up technologically to the US. Another example that may be less familiar to many people is Singapore (the second fastest growing economy from 1960 to 2000 in Barro's data set of 112 countries) that is best thought of as catching up to the world's technological leaders (the G5 countries with whom it trades extensively and from where it receives substantial foreign direct investments) and that saw its unemployment rate go down from double-digit levels in the early 1960's to the low 2 to 3 percent in the late 1990's. How much of the big movements in the unemployment rate can be explained by non-monetary factors in a model of an endogenous natural rate exhibiting both monetary neutrality and super-neutrality? What room is left for monetary policy in explaining the movements of the unemployment rate? The paper develops the theory and seeks to ask how much non-monetary factors can quantitatively account for the evolution of the unemployment rate. |

| Abstract: | We ask why, in many circumstances and many environments, decision-makers choose to act on a time-regular basis (e.g. adjust every six weeks) or on a stateregular basis (e.g. set prices ending in a 9), even though such an approach appears suboptimal. The paper attributes regular behaviour to adjustment cost heterogeneity. We show that, given the cost heterogeneity, the likelihood of adopting regular policies depends on the shape of the benefit function: the flatter it is, the more likely, ceteris paribus, is regular adjustment. We provide sufficient conditions under which, when policymakers differ with respect to the shape of the benefit function (as in Konieczny and Skrzypacz, 2006), the frequency of adjustments across markets is negatively correlated with the incidence of regular adjustments. On the other hand, if policymakers differences are due to the level of adjustment costs (as in Dotsey, King and Wolman, 1999), then the correlation is positive. To test the model we apply it to optimal pricing policies. We use a large Austrian data set, which consists of the direct price information collected by the statistical office and covers 80% of the CPI over eight years. We run cross-sectional tests, regressing the proportion of attractive prices and, separately, the excess proportion of price changes at the beginning of a year and at the beginning of a quarter, on various conditional frequencies of adjustment, inflation and its variability, dummies for good types, and other relevant variables. We find that the lower is, in a given market, the conditional frequency of price changes, the higher is the incidence of time- and state-regular adjustment. |

| Abstract: | The paper explores the determinants of yield differentials between sovereign bonds in the Euro area. There is a common trend in yield differentials, which is correlated with a measure of aggregate risk. In contrast, liquidity differentials display sizeable heterogeneity and no common factor. We propose a simple model with endogenous liquidity demand, where a bond’s liquidity premium depends both on its transaction cost and on investment opportunities. The model predicts that yield differentials should increase in both liquidity and risk, with an interaction term of the opposite sign. Testing these predictions on daily data, we find that the aggregate risk factor is consistently priced, liquidity differentials are priced for a subset of countries, and their interaction with the risk factor is in line with the model’s prediction and crucial to detect their effect. |

| Abstract: | Many problems emerge since it is widely believed that high tax rates and ineffective tax collection by government are the main causes contributing to the rise of the informal economy. Already the economists have established a relationship between tax rates and tax evasion or size of the informal economy. The higher is the level of taxation, the greater incentive is to participate in informal economic activities and escape taxes. At the macroeconomic level, there is a number of so-called indirect methods used to estimate the size and dynamics of informal economy, reported in literature as “Monetary Approach”, “Implicit Labour Supply Method”, “National Accountancy”, “Energy Consumption Method”, etc. Unfortunately, many times there are huge differences among the estimated shares of informal or underground economy obtained by various methods. For instance, in case of Romania the figures are between about 20% of GDP, obtained on the base of the energy consumption method and more than 45% computed by using the monetary approach. Also, the figures reported by the National Institute for Statistics (NIS), based on national accounts methodology, increased (mainly due to changes in methodology) from about 5% in 1992, to 18% in 1997 and to 20-22% after 2000. Adding to these figures about 7% of GDP, representing the estimated level for self-consumption in case of a rural household, legal non-registered but informal, resulted that last years the informal economy is responsible of 27-29% of national economy. In this article, coming from certain general accepted finding of the theory in matter of modelling underground economy, we concentrate on evaluating analytically the limit-values of certain important parameters involved in models used to estimate the size of underground economy and to explain the mechanisms of its dynamics. Then we shall simulate some exercises on available data. The second goal of the paper is to report some conclusions of our investigation based on data supplied by special surveys organised in Romania. Also, in order to see since certain hypotheses (referring to the complex transmission mechanism from the tax policy decisions to the effective implication of agents into informal economy) are statistically verified and to extend the study from the aggregate level to a deep research inside the population set in regions, we used data supplied by this special large survey, which already were processed and are available in our database. |

| Abstract: | Labor's share of GDP in most OECD countries has declined over the last two decades. Someauthors have suggested that these changes are linked to deregulation of product and labormarkets. To examine this we focus on a large quasi-experiment in the OECD: theprivatization of many network industries (e.g. telecommunications and utilities). We present amodel with agency problems, imperfect product market competition and worker bargainingwhich makes clear predictions on how the labor share, employment and wages respond toprivatization and other regulatory changes. We exploit cross-country panel data on severalnetwork industries and find that privatization can account for a significant proportion of thefall of labor's share (a fifth overall, but over half in Britain and France). The impact ofprivatization has been offset by falling barriers to entry, which consistent with theory,dampens profit margins. |

| Abstract: | This paper provides estimates for the base elasticities of Dutch taxes, paying particular attention to differences between short-and long-term elasticities, and allowing for asymmetric adjustment. Estimates are presented for five tax categories for the period 1970-2005, after making appropriate corrections for effects of discretionary tax measures. The empirical results indicate that shortterm elasticities often are lower than long-term ones, notably when taxes are subdued. Consequently, shocks to tax revenues tend to be aggravated by the dynamics of short-term elasticities. Ignoring differences between short- and long-term elasticities contributes to revenue ‘surprises’ and an incorrect assessment of the fiscal stance. JEL Classification: H2, H62, H68. |

| Abstract: | In applications as diverse as banking, supermarket and catalogue sales, it has been clearly identified that prices have a strong propensity to cluster around certain digits. This study forwards an explanation and empirical investigation of price clustering in retail markets, through an examination of how interest rates cluster in two UK financial services markets. It is proposed that price or interest rate clustering forms in retail markets as firms wish to maximise returns from customers who have difficulties in recalling and processing price information. To compensate for limited recall, individuals use different behavioural strategies, such as rounding and truncating number information, which are recognised by firms when setting prices or interest rates. This theory is developed and tested using a dataset of retail interest rates from the UK which enables interest rate clustering to be viewed in both lending and investment markets, and at different levels of financial involvement. It is found that interest rate clustering occurs in a manner consistent with firms maximising returns from customers who have less ability in recalling and processing number information. Further, the degree of interest rate clustering observed is exaggerated for investors of smaller monetary quantities, for firms which profit maximise and at higher market rates of interest. |

| Abstract: | In large random economies with heterogeneous agents, a standard stochastic framework presumes a random macro state, combined with idiosyncratic micro shocks. This can be formally represented by a ran-dom process consisting of a continuum of random variables that are conditionally independent given the macro state. However, this process satisfies a standard joint measurability condition only if there is essentially no idiosyncratic risk at all. Based on iteratively complete product measure spaces, we characterize the validity of the standard stochastic framework via Monte Carlo simulation as well as event-wise measurable conditional probabilities. These general characterizations also allow us to strengthen some earlier results related to exchangeability and independence. |

| Abstract: | We investigate identifiability issues in DSGE models and their consequences for parameter estimation and model evaluation when the objective function measures the distance between estimated and model impulse responses. Observational equivalence, partial and weak identification problems are widespread and they lead to biased estimates, unreliable t-statistics and may induce investigators to select false models. We examine whether different objective functions affect identification and study how small samples interact with parameters and shock identification. We provide diagnostics and tests to detect identification failures and apply them to a state-of-the-art model. |

| Abstract: | The aim of this paper is to apply recently developed panel cointegration techniques proposed by Pedroni (1999, 2004) and generalized by Banerjee and Carrion-i-Silvestre (2006) to examine the robustness of the PPP concept for a sample of 80 developed and developing countries. We find that strong PPP is verified for OECD countries and weak PPP for MENA countries. However in African, Asian, Latin American and Central and Eastern European countries, PPP does not seem relevant to characterize the long-run behavior of the real exchange rate. Further investigations indicate that the nature of the exchange rate regime doesn’t condition the validity of PPP which is more easily accepted in countries with high than low inflation. |

| Abstract: | Evidence suggests that unemployed individuals can sometimes affect their job prospects by undertaking a costly action like deciding to move or retrain. Realistically, such an opportunity only arises for some individuals and the identity of those may be unobservable ex-ante. The problem of characterizing constrained optimal unemployment insurance in this case has been neglected in previous literature. We construct a model of optimal unemployment insurance where multiple incentive constraints are easily handled. The model is used to analyze the case when an incentive constraint involving moving costs must be respected in addition to the standard constraint involving costly unobservable job-search. In particular, we derive closed-form solutions showing that when the moving/retraining incentive constraint binds, unemployment benefits should increase over the unemployment spell, with an initial period with low benefits and an increase after this period has expired. |

| Abstract: | The Ramsey optimal taxation theory implies that the tax rate on capital income should be zero in the long run. This result holds even if the social planner only cares about workers that do not hold assets, or if the planner only cares about any other group in the economy. This paper demonstrates that although all households agree that capital income taxation should be eliminated in the long run, they do not agree on how to eliminate these taxes. Wealthy households would prefer a reform that is funded by higher taxes on labour income while households with little wealth would prefer a reform that is funded mostly by high taxes on initial wealth. Pareto improving reforms typically exist, but the welfare gains of such reforms are modest. |

| Abstract: | Real investors and markets are too complicated to be neatly summarized by a few selected biases and trading frictions. The "top down" approach to behavioral finance focuses on the measurement of reduced form, aggregate sentiment and traces its effects to stock returns. It builds on the two broader and more irrefutable assumptions of behavioral finance -- sentiment and the limits to arbitrage -- to explain which stocks are likely to be most affected by sentiment. In particular, stocks of low capitalization, younger, unprofitable, high volatility, non-dividend paying, growth companies, or stocks of firms in financial distress, are likely to be disproportionately sensitive to broad waves of investor sentiment. We review the theoretical and empirical evidence for these predictions. |

| Abstract: | This paper estimates a single-equation model to analyse the main explanatory factors behind changes in Spanish household credit, considering that the behaviour of its determinants is exogenous. According to the evidence reported, household borrowing is determined in the long run by real spending, gross wealth and the repayment term for outstanding credits, which have a positive influence, and by the cost of loans and the unemployment rate, the effect of which is of a negative sign. Developments in the short run are influenced by changes in long-term interest rates and in employment. The evidence offered suggests that, in general terms, the financing received by households over the period analysed is in line with what may be inferred from its determinants; however, the high volume of debt incurred entails greater exposure of the sector to unexpected changes in its income, in its wealth or in the cost of borrowing, especially in a setting in which floating-rate loans are increasingly significant. |

| Abstract: | We study the effects of liquidity constraints and start-up costs on the relationship between wealth and the fraction of entrepreneurs in an economy. We develop a dynamic occupational choice model with endogenous wealth and entry into entrepreneurship. The model predicts that, with liquidity constraints, the probability of entering entrepreneurship is an increasing function of individual wealth while the introduction of start-up costs tends to flatten this relationship. The theoretical predictions can be tested on cross-sectional data with exogenous variation in liquidity constraints (e.g. access to credit) and business start-up costs. We use three highly comparable micro datasets (SHARE, ELSA and HRS) providing harmonized data on wealth and work status in 9 countries that characterized by very different levels of start-up costs and liquidity constraints. Our results support our theoretical predictions. While higher liquidity constraints yield a positive relationship with wealth profile for the fraction of workers in entrepreneurship, start-up costs weaken this relationship by depressing the marginal value of being an entrepreneur as a function of wealth. Countries with high start-up costs such as Italy, Spain and France have flatter wealth gradients. |

| Abstract: | This paper complements conventional economic analysis and presents a social norms interpretation to explain cross-country differences in partnership formation rates, and the dramatic decrease in partnership formation rates in Southern Europe in particular. We argue that increases in female human capital - by raising the opportunity cost of entering a partnership - had a differential impact on partnership formation rates in Northern and Southern Europe due to the different social norms regarding the household division of labor. Social norms are modeled as a constraint on the allocation of household labor that (if binding) diminishes the gains to enter a partnership. Furthermore, highly educated women are less likely to form a partnership, because the utility loss when a partnership is formed is lower the higher the female opportunity cost. We test the predictions of the model using 7 waves of the European Community Household Panel (1995-2001). For each country and year we construct the average of the female to male ratio of childcare time as an indicator of social norms regarding the household division of labor. The empirical findings support the predictions of the model. After controlling for the time and country variation in the data, as well as for permanent individual heterogeneity and other aggregate variables at the country level, the results suggest that more traditional social norms regarding the household division of labor negatively affect a woman's probability of forming a partnership. Thus, a woman living in a country with a more traditional division of household labor has, ceteris paribus, a lower probability of forming a partnership. Furthermore, as predicted by the theory, social norms have a stronger negative effect for highly educated women. To the extent that female education has increased over the years, and that Southern European countries have more traditional social norms, this latter finding may partly explain the dramatic decrease in partnership formation rates in Southern Europe. |

| Abstract: | This paper examines the connection between illegal migration, minimum wages and enforcement policy. We first explore the employers’ decision regarding the employment of illegal migrants in the presence of an effective minimum wage. We show that the employers’ decision depends on the wage gap between those of the legal and illegal workers and on the penalty for employing illegal workers. We consider the effects a change in the minimum wage has on the employment of illegal immigrants and local workers. We conclude by considering the optimal migration policy taking into consideration social welfare issues. |
