In most macroeconomic models, the substitutability between domestic and foreign goods is calibrated using aggregated data. This imposes homogeneous elasticities across goods, and the calibration is only valid under this assumption. If elasticities are heterogeneous, the aggregate...

There is a widespread view that the adjustment of U.S. trade prices--and hence merchandise trade flows--in the face of the substantial dollar depreciation since early 1985 has been slower than might have been expected. This paper examines the recent behavior of U.S. trade prices, and concludes...

Trade integration can play a much larger role in boosting shared prosperity. The current focus on trade tensions threatens to obscure the great untapped benefits possible from further trade reform. The opportunities provided by information technology and other fundamental changes in the global...

In addition to transferring about 16 percent of GDP from exporters to importers, Uzbekistan’s quasi-fiscal multiple exchange rate regime generates identifiable welfare losses of 2-8 percent of GDP on import markets and up to 15 percent on export markets. These excess burdens have increased...

Many arguments that have been advanced in favor of maintaining capital controls within the EC have not paid sufficient attention to the welfare consequences of this type of market intervention. Our paper provides a simple, optimizing framework in which the welfare consequences of capital...

The paper proposes a new welfare-based measure to evaluate the distributive effects of public programs. The proposed measure differs from traditional approaches in two important ways: first, it is based on life-cycle considerations, since most public expenditure programs have an intertemporal...

A simple two-country stochastic model is used to analyze monetary policy interaction in a system of exchange rate bands such as the EMS, in the context of internationally-integrated financial markets. We consider the widely-acknowledged asymmetry of the system, as it pertains to member...

This paper develops a political-economy model of the budget process focusing on the common pool problem of the public budget. We show that the externality arising from the fact that public spending tends to be targeted at individual groups in society while the tax burden is widely dispersed...
