Abstract: | The paper shows how a dynamic neoclassical AS-AD can be derived and used to describe business cycles and growth trends to undergraduates. Derived within the Ramsey-Cass-Koopmans (RCK) model, the AS-AD is the stationary equilibrium of the deterministic dynamic general equilibrium framework. Allowing Solow exogenous growth, the AS-AD is derived along the balanced growth path equilibrium. The derivation first builds consumption demand, aggregate demand, and then aggregate supply through the equilibrium conditions and a closed form solution for the capital stock. Through a comparative static change in goods sector productivity, the paper shows the basic failing of the standard RBC model. Allowing a second comparative static change in the consumer's time endowment, this captures a change in the "external margin" of labor supply. These comparative statics enable explanation of the business cycle, and "Solow-plus" growth trends including education time and working time. In extension of RCK, the paper shows beyond the undergraduate level, how to derive AS-AD when including human capital and endogenous growth. This allows an endogenous change in the time endowment for work and leisure through a change in human capital productivity, with a similar but more fundamental AS-AD story of business cycles and growth trends. |

Abstract: | This paper considers the impact on optimal tax policy of including endogenously determined retirement in a life cycle model. Allowing individuals to determine when they retire causes the optimal tax on capital to increase by 75% because of two implicit changes in the aggregate labor supply elasticity. First, including endogenous retirement causes an increase in the overall aggregate labor supply elasticity since agents can change their labor supply on both the intensive and extensive margins. In response, the government limits the distortions from the tax policy by lowering the tax on labor and increases the tax on capital. Second, given that the choice to retire is more relevant for older individuals, endogenous retirement disproportionately increases older agent's elasticity compared to younger individuals. Ideally, the government would decrease the relative labor income tax on individuals when they are older and supply labor more elastically. However, in the absence of age-dependent taxes, the government mimics such a tax policy by further increasing the tax on capital. I find that the welfare lost from not accounting for endogenous retirement when solving for the optimal tax policy is equivalent to approximately one percent of lifetime consumption. |

Abstract: | We show that self-fulfilling equilibria and indeterminacy can easily arise in a simple financial accelerator model with reasonable parameter calibrations and without increasing returns in production. A key feature for generating indeterminacy in our model is the countercyclical markup due to the procyclical loan to output ratio. We illustrate, via simulations, that our financial accelerator model can generate rich business cycle dynamics, including hump-shaped output in response to demand shocks as well as serial autocorrelation in output growth rates. |

Abstract: | We model an oligopolistic industry that supplies intermediate goods in an overlapping generations economy. Agents can choose whether to provide labour or to become entrepreneurs and compete in the industry. The idea that entry is determined through occupational choice has major implications for the industry’s dynamics. We find that the industry’s convergence to the steady state equilibrium occurs through cyclical fluctuations, despite the lack of any type of exogenous shocks. Furthermore, the path of convergence is not uniquely determined, implying that differences in economic performance may not necessarily reflect differences in either structural characteristics or initial conditions. |

Abstract: | We develop a model of retirement and human capital investment to study the effects of tax and retirement policies. Workers choose the supply of raw labor (career length) and also the human capital embodied in their labor. Our model explains a significant fraction of the US-Europe difference in schooling and retirement. The model predicts that reforms of the European retirement policies modeled after the US can deliver 15-35 percent gains in per-worker output in the long run. Increased human capital investment in and out of school accounts for most of the gains, with relatively small changes in career length. JEL classification: E24; J24 |

Abstract: | The bargaining power of international banks is currently still very high as compared to what it was at the time of the Bretton Woods conference. As a consequence, systemic financial crises are likely to remain recurrent phenomena with large effects on macroeconomic aggregates. Mainstream macroeconomic models dealing with financial frictions failed to explain at least eight features of the ongoing crisis. We therefore suggest two complementary assumptions : (I) A systemic bankruptcy risk stable equilibrium may be feasible, besides another stable equilibrium related to a stability corridor, (II) inefficient financial markets rarely ensure that the price of an asset is equal to its "fundamental long term value". Both assumptions are compatible with a structural research programme taking into account the Lucas' critique (1976) but may start a creative destruction process of the Lucas' view of business cycles theory. |

Abstract: | A two-sector OLG model illuminates previously unexamined intergenerationaleffects of a tax that protects an environmental stock. A traded asset capitalizes the economic returns to future tax-induced environmental improvements, benefiting the current asset owners, the old generation. Absent a transfer, the tax harms the young generation by decreasing their real wage. Future generations benefit fromthe tax-induced improvement in environmental stock. The principalintergenerational conflict arising from public policy is between generationsalive at the time society imposes the policy, not between generations alive at different times. A Pareto-improving policy can be implemented under various political economy settings. |

Abstract: | Many dynamic problems in economics are characterized by large state spaces which make both computing and estimating the model infeasible. We introduce a method for approximating the value function of high-dimensional dynamic models based on sieves and establish results for the: (a) consistency, (b) rates of convergence, and (c) bounds on the error of approximation. We embed this method for approximating the solution to the dynamic problem within an estimation routine and prove that it provides consistent estimates of the model's parameters. We provide Monte Carlo evidence that our method can successfully be used to approximate models that would otherwise be infeasible to compute, suggesting that these techniques may substantially broaden the class of models that can be solved and estimated. |

Abstract: | We imbed a classic fishery model, where the optimal policy follows a Most Rapid Approach Path to a steady state, into an overlapping generations setting. The current generation discounts future generations’ utility flows at a rate possibly different from the pure rate of time preference used to discount their own utility flows. The resulting model has non-constant discount rates, leading totime inconsistency. The unique Markov Perfect equilibrium to this model hasa striking feature: provided that the current generation has some concern forthe not-yet born, the equilibrium policy does not depend on the degree of thatconcern. |

Abstract: | This paper uses a New Keynesian DSGE model of a small open economy to compare how the effects of fiscal consolidation differ depending on whether monetary policy is constrained by currency union membership or by the zero lower bound on policy rates. We show that there are important differences in the impact of fiscal shocks across these monetary regimes that depend both on the duration of the zero lower bound and on features that determine the responsiveness of inflation. |

Abstract: | This paper studies the impact of bank regulation and taxation in a dynamic model where banks are exposed to credit and liquidity risk and can resolve financial distress in three costly forms: bond issuance, equity issuance or fire sales. We find an inverted U-shaped relationship between capital requirements and bank lending, efficiency, and welfare, with their benefits turning into costs beyond a certain threshold. By contrast, liquidity requirements reduce lending, efficiency and welfare significantly. On taxation, corporate income taxes generate higher government revenues and entail lower efficiency and welfare costs than taxes on non-deposit liabilities. -- |

Abstract: | In this paper we analyzed a model of endogenous fertility in presence of financial market assets and social security pensions. Given the children externality and in the absence of corrective policy, the fertility rate chosen in market economy is too low. Indeed, in his optimal choice of family size, the representative household does not take into account of this children externality which leads to a sub optimal demography. We have shown that an optimal demographic allocation exists and can be implemented through a subvention taxation policy if it is available |

Abstract: | We study a labor market in which principals and agents must search for a trading partner, and agents have private information about the value of a match. We show that competitive pressure can induce agents to lie and over-state the value of the match. This leads to insufficient frictional unemployment and search, and lower average productivity and utility. A fully tax-financed unemployment insurance can therefore eliminate the inefficiency. Moreover, because inefficient “job-hoarding” by workers occurs when there are many workers per job, the analysis provides a novel explanation for the stylized macroeconomic fact that labor productivity is procyclical. |

Abstract: | We develop a dynamic stochastic model of a middle-income, small open economy with a two-level banking intermediation structure, a risk-sensitive regulatory capital regime, and imperfect capital mobility. Firms borrow from a domestic bank and the bank borrows on world capital markets, in both cases subject to an endogenous premium. A sudden flood in capital flows generates an expansion in credit and activity, and asset price pressures. Countercyclical regulation, in the form of a Basel III-type rule based on real credit gaps, is effective at promoting macroeconomic stability (defined in terms of the volatility of a weighted average of inflation and the output gap) and financial stability (defined in terms of the volatility of a composite index of the nominal exchange rate and house prices). However, because the gain in terms of reduced volatility may exhibit diminishing returns, a countercyclical regulatory rule may need to be supplemented by other, more targeted, macroprudential instruments. |

Abstract: | The interaction between credit frictions, financial innovation, and a switch from optimistic to pessimistic beliefs played a central role in the 2008 financial crisis. This paper develops a quantitative general equilibrium framework in which this interaction drives the financial amplification mechanism to study the effects of macro-prudential policy. Financial innovation enhances the ability of agents to collateralize assets into debt, but the riskiness of this new regime can only be learned over time. Beliefs about transition probabilities across states with high and low ability to borrow change as agents learn from observed realizations of financial conditions. At the same time, the collateral constraint introduces a pecuniary externality, because agents fail to internalize the effect of their borrowing decisions on asset prices. Quantitative analysis shows that the effectiveness of macro-prudential policy in this environment depends on the government's information set, the tightness of credit constraints and the pace at which optimism surges in the early stages of financial innovation. The policy is least effective when the government is as uninformed as private agents, credit constraints are tight, and optimism builds quickly. |

Abstract: | This paper estimates matching functions to measure search frictions in the Japanese labor market and presents determinants of search duration to explain the effect of unemployment benefits on a job seekerfs behavior. We employ administrative micro data that track the job search process of individuals who left or lost their job in August 2005 and subsequently registered at their local public employment service. Our finding is that the matching function would exhibit decreasing returns-to-scale for job seekers and vacancies, rather than constant return-to-scale. We also find that generous unemployment benefits lengthen (shorten) the duration of job search for job seekers who voluntarily (involuntarily) leave employment. |

Abstract: | We develop a two-period, three-class of income model where low-income agents are borrowing constrained because of capital market imperfections, and where redistributive expenditure is financed by tax and government debt. When the degree of capital market imperfection is high, there is an ends-against-the-middle equilibrium where the constrained low-income and the unconstrained high-income agents favor low levels of government debt and redistributive expenditure; these agents form a coalition against the middle. In this equilibrium, the levels of government debt and expenditure might be below the efficient levels, and the spread of income distribution results in a lower debt-to-GDP ratio. |

Abstract: | This paper proposes an endogenous growth model with an essential non-renewable resource, where economic growth enables firms to invest in innovation in the extraction technology and to allocate more capital to resource extraction. Innovation in the extraction technology offsets the deterioration of ore qualities and keeps the production costs of the non-renewable resource constant. Aggregate output as well as production and use of the non-renewable resource increase exponentially. Our model explains the long-run trends of non-renewable resource prices and world production over more than 200 years. If historical trends in technological progress and in the deterioration of ore qualities continue, it is in the realm of possibility that non-renewable resources are de facto inexhaustible. Our results suggest that the industrialization in China and other emerging economies contributes to keeping non-renewable resource prices constant in the long run. |

Abstract: | This paper discusses monetary and fiscal interactions in fiscal stress with no outright default. Two distortions prevail in the economy: income taxes and liquidity constraints. Possible obstructions to fiscal policy include: a ceiling on the equilibrium Debt-to-GDP ratio; zero elasticity of tax revenues; a political intolerance of rising tax rates; A Laffer curve emerges endogenously. In equilibrium, fiscal solvency is brought about through adjustments to the level of nominal prices. Three regimes achieve this goal: FC - an interaction of a fiscal rule that targets both output and public debt with a neutral monetary policy; FD - an interaction of a fiscal rule that targets the primary deficit with an active monetary policy; FDA - an interaction of an austere fiscal rule with a passive monetary policy. |

Abstract: | We provide an analysis that might help distinguish rationally justified movements in house prices from potentially non-rational movements, using a two-sector business cycle model, in which investment in housing is subject to collateral constraints. A large portion of the evolution of U.S. house prices during the past 20 years can be reproduced when expectations of future income growth as published in surveys are used as an input into the model. Changes in growth expectations translate into corresponding changes in house prices, since the value of housing must be linked to expected aggregate income. Only since about 2005 do actual and model-implied house prices clearly diverge, calling for explanations not based on economic fundamentals. -- |

Abstract: | We consider a growth model with education, externalities and a cultural norm . We show that endogenous emergence of this cultural belief may lead to increasing the stock of human capital and accelerating national growth.The mechanism of this internalization is based on the existence of endogenous social status or identity pattern that encourages to the accumulation of knowledge. This cultural norm is presented as an informal mechanism which may be an effective substitute tool to a the formal institution given by a system of income taxation. |

Abstract: | We show that credit market imperfections substantially increase the government-spending multiplier when the economy enters a liquidity trap. This finding is explained by the tight association between capital goods and rmscollateral, a relationship that we highlight as the capital-accumulation channel. During a liquidity trap, a government spending expansion reduces the real interest rate, leading to a period of cheap credit. Entrepreneurs use this time to accumulate capital, which persistently improves their balance sheets and reduces their future costs of credit. A public spending expansion can thus encourage private investment, yielding consequently a large spending multiplier. This effect is further reinforced by Fishers debt- deation channel. |

Abstract: | We examine the evolution of the effects of monetary policy shocks on the distribution of disaggregate prices and quantities of personal consumption expenditures to assess the contribution of monetary policy to changes in U.S. inflation dynamics. Given that the transmission of monetary policy to aggregate inflation is determined by the responses of its underlying components, the degree of monetary non-neutrality is ultimately the result of relative price effects at the sectoral level. We provide evidence of considerable heterogeneity in sectoral price responses by introducing time variation in a factoraugmented vector autoregression model. Over time the majority of individual prices respond negatively after a contractionary monetary policy shock and the price dispersion diminishes. We link these empirical findings to a multi-sector DSGE model and show that they are consistent with firms’ heterogeneous pricing decisions and changes in the importance of the cost channel of monetary policy and the degree of wage flexibility. |

Abstract: | We investigate whether expectations that are not fully rational have the potential to explain the evolution of house prices and the price-to-rent ratio in the United States. First,a Lucas type asset-pricing model solved under rational expectations is used to derive a fundamental value for house prices and the price-rent ratio. Although the model can explain the sample average of the price-rent ratio, it does not generate the volatility and persistence observed in the data. Then, we consider an intrinsic bubble model and two models of extrapolative expectations developed by Lansing (2006, 2010) in applications to stock prices: one that features a constant extrapolation parameter and one in which the extrapolation coefficient depends on the dividend growth process. We show that these last two models are equally good at matching sample moments of the data. However, a counterfactual experiment shows that only the extrapolative expectation model with timevarying extrapolation coefficient is consistent with the run up in house prices observed over the 2000-2006 period and the subsequent sharp downturn. |

Abstract: | This paper posits a notion of the value of an individual's human capital and the associated return on human capital. These concepts are examined using U.S. data on male earnings and financial asset returns. We decompose the value of human capital into a bond, a stock and a residual value component. We find that (1) the bond component of human capital is larger than the stock component at all ages, (2) the value of human capital is far below the value implied by discounting earnings at the risk-free rate, (3) mean human capital returns exceed stock returns early in life and decline with age and (4) human capital returns and stock returns have a small positive correlation over the working lifetime. |

Abstract: | Endogenous growth theory has deeply influenced regional growth analyses and inspired regional development policies. Evidence of lack of convergence, club convergence and spatial polarization of per worker income levels has led scholars to question the explanatory power of neoclassical exogenous growth models and to look at endogenous growth theories as proper frameworks to interpret regional development. In particular, those models, which emphasize the role of knowledge spillovers as driving forces for economic growth and identify a large set of self- reinforcing mechanisms that can potentially cause low-productivity traps, have become central in the scientific debate. Only during the last ten years, however, there have been some analytical attempts to regionalize endogenous growth theory. This paper provides a critical survey of the growing literature on regional extensions of endogenous growth analysis. The focus is on those theoretical and empirical studies which have tried to explain lack of regional convergence, multiple equilibria and spatial polarization. The paper also suggests some directions for future research in this field. |
