This paper examines the effects of trade costs on macroeconomic volatility. We first construct a dynamic, two-country general equilibrium model, where the degree of market integration depends directly on trade costs (transport costs, tariffs, etc.). The model is a extension of Obstfeld and...

A view receiving increased support is that the height of trade costs in prime export sectors has a strong effect on current account balances: countries specializing in sectors that face relatively high trade costs, such as services, tend to run current account deficits, and similarly, countries...

Feldstein and Horioka (1980) argued that the correlation of saving and investment in a cross-section of countries may provide a test of global capital mobility. This paper argues that neither the long-run nor the short-run correlation can serve as a reliable basis for such a test. The...

This paper uses panel data for 19 OECD countries and finds support for the hypothesis that a greater degree of product variety relative to the United States helps to explain relative per capita GDP levels. The empirical work relies upon some direct measures of product variety calculated from...

This paper asks whether inflation targeting improves economic performance, as measured by the behavior of inflation, output, and interest rates. We compare 7 OECD countries that adopted inflation targeting in the early 1990s to 13 that did not. After the early 1990s, performance improved along...

This paper examines the extent to which conclusions of cross-country studies of private savings are robust to allowing for the possible heterogeneity of savings behavior across countries and the inclusion of dynamics. It shows that neglecting heterogeneity and dynamics can lead to misleading...

This paper constructs a general equilibrium model with monopolistically competitive firms and endogenous markups where government spending consists of both consumption and investment goods. It is shown that when markups are countercyclical, increases in the share of investment goods in aggregate...
