| Abstract: | The rational expectations hypothesis swept through macroeconomics during the 1970’s and permanently altered the landscape. It remains the prevailing paradigm in macroeconomics, and rational expectations is routinely used as the standard solution concept in both theoretical and applied macroeconomic modelling. The rational expectations hypothesis was initially formulated by John F. Muth Jr. in the early 1960s. Together with Robert Lucas Jr., Thomas (Tom) Sargent pioneered the rational expectations revolution in macroeconomics in the 1970s. We interviewed Tom Sargent for Macroeconomic Dynamics. |

| Abstract: | This paper compares alternative monetary policy rules in a model of an emerging market economy that experiences external shocks to world interest rates and the terms of trade. The model is a two-sector dynamic open economy, with endogenous capital accumulation and slow price adjustment. Two key factors are highlighted in examining the response of the economy to shocks, and in the assessment of the effectiveness of monetary rules.These are: a) balance-sheet related financial frictions in capital formation; and b) delayed pass-through of changes in exchange rates to imported goods prices. We find that, while financial frictions cause a magniFcation of real and financial volatility, they have no effect on the comparison or ranking of alternative monetary policies. But the degree of exchange rate pass-through is very important for the assessment of monetary rules. With high pass-through, there is a trade-off between between real stability (in output or employment) and inflation stability. Moreover, the best monetary policy rule in this case is to stabilise non-traded goods prices. But, with delayed pass-through, the same trade off between real stability and inflation stability disappears, and the best monetary policy rule is CPI price stability Classification- |

| Abstract: | In time series from the United States, the relationship between the money to income ratio and the nominal interest rate is a negative and stable one. In Swedish data, there is no such stable relationship. In this paper, we argue that this difference can be explained by the differences in the shock processes that have hit the two countries. Using a dynamic general equilibrium model driven by shock processes estimated to fit the two countries, we find that we can account for the main properties of the data remarkably well. |
