This paper examines whether the Solow growth model is consistent with the international variation in the standard of living. It shows that an augmented Solow model that includes accumulation of human as well as physical capital provides an excellent description of the cross-country data. The...

Because unanticipated monetary expansion leads to real exchange rate depreciation and because the harms of real depreciation are greater in more open economies, the benefits of unanticipated expansion are decreasing in the degree of openness. Models in which the absence of precommitment in...

From the early 1950s to the early 1990s, increases in Social Security benefits in the United States varied widely in size and timing, and were only rarely undertaken in response to short-run macroeconomic developments. This paper uses these benefit increases to investigate the macroeconomic...

This paper investigates monetary policy's influence on poverty and inequality in both the short run and the long run. We find that the short-run and long-run relationships go in opposite directions. The time-series evidence from the United States shows that a cyclical boom created by...

This paper investigates the impact of changes in the level of taxation on economic activity. We use the narrative record -- presidential speeches, executive-branch documents, and Congressional reports -- to identify the size, timing, and principal motivation for all major postwar tax policy...

Countries' geographic characteristics have important effects on their trade, and are plausibly uncorrelated with other determinants of their incomes. This paper therefore constructs measures of the geographic component of countries' trade and uses those measures to obtain instrumental variables...

This paper argues that an important part of movements in asset prices may be caused by neither external news nor irrationality, but the by revelation of information by the trading process itself. Two models are developed that illustrate this general idea. One model is based on investor...

Estimates of growth equations have found a role for openness, particularly in explaining rapid growth among East Asian countries. But major concerns of simultaneous causality between growth and trade have been expressed. This study aims to deal with the endogeneity of trade by using as...

These two volumes bring together a set of important essays that represent a "new Keynesian" perspective in economics today. This recent work shows how the Keynesian approach to economic fluctuations can be supported by rigorous microeconomic models of economic behavior. The essays are grouped in...
