Cyclical movements in aggregate output, factor inputs, and productivity are all positively correlated across countries. This article proposes a model in which positive cross-country correlations of these variables result from increasing returns to the world-wide variety of intermediate goods...

Many international macroeconomic models link the real exchange rate to a ratio of marginal utilities. We examine this link empirically, allowing the marginal utility of consumption to depend on government expenditure, real money balances, or external habit. We also consider two environments with...

The dynamic effects of government spending are considered in a general equilibrium model with monopolistic competition and increasing returns. In the economy, changes in the level of government spending endogenously raise total factor productivity, even though the spending itself is entirely...

Using micro-level data for the U.S., we provide new evidence - at national and state levels - of a positive (negative) relationship between the standard deviation (coefficient of variation) and the average in bank lending-rate markups. In a quantitative theory consistent with these empirical...
