By looking at how an East Asian currency moves when the yen fluctuates sharply against the US dollar, we sometimes find that the reaction has been much more significant than would be suggested by the econometric estimates of the weight of the yen in nominal exchange rate determination. Moreover,...

I discuss the role of economic theory in empirical work in development economics with special emphasis on general equilibrium and political economy considerations. I argue that economic theory plays (should play) a central role in formulating models, estimates of which can be used for...

Theoretical advances in macroeconomics made in the last three decades have had a major influence on macroeconomic policy analysis. Moreover, over the last several decades, the United States and other countries have undertaken a variety of policy changes that are precisely what macroeconomic...

This paper develops a decision-theoretic approach to policy analysis. We argue that policy evaluation should be conducted on the basis of two factors: the policymaker's preferences, and the conditional distribution of the outcomes of interest given a policy and available information. From this...

Instrumental variables (IV) estimation of a demand equation using time series data is shown to produce a weighted average derivative of heterogeneous potential demand functions. This result adapts recent work on the causal interpretation of two-stage least squares estimates to the simultaneous...

We analyze how relative wage movements across birth cohorts and education groups during the 1980s affected the distribution of household consumption. The analysis integrates the labor economics literature on time variation in the wage structure with the consumption insurance literature. In...

Sir John Hick's Value and Capital provided the theoretical foundation for an important element of modern macroeconomics. Intertemporal substitution - deferral or acceleration of economic activity in response to the real interest rate and other incentives - is the mechanism generally relied upon...
