An optimal linear world income tax that maximizes a border-neutral social welfare function provides a drastic reduction in world consumption inequality, dropping the Gini coefficient from 0.69 to 0.25. In contrast an optimal decentralized (i.e., within countries) redistribution has miniscule...

This paper studies the effect of foreign aid on economic stabilization. Following Alesina and Drazen (1991), we model the delay in stabilizing as the result of a distributional struggle: reforms are postponed because they are costly and each distributional faction hopes to reduce its share of...

Although institutions are believed to be key determinants of economic performance, there is limited evidence on how they can be successfully reformed. Evaluating the effects of specific reforms is complicated by the lack of exogenous variation in the presence of institutions; the difficulty of...

This paper examines the effect of U.S. food aid on conflict in recipient countries. To establish a causal relationship, we exploit time variation in food aid caused by fluctuations in U.S. wheat production together with cross-sectional variation in a country's tendency to receive any food aid...

Using a variance decomposition of shocks to GDP, we quantify the role of international factor income, international transfers, and saving in achieving risk sharing during the recent European crisis. We focus on the sub-periods 1990-2007, 2008-2009, and 2010 and consider separately the European...

Following the rationale for regional redistribution programs described in the official documents of the European Union, this paper studies a very simple multi-country model built around two regions: a core and a periphery. Technological spill-overs link firms' productivity in each of the two...

The occupation payments made by France to Nazi Germany between 1940 and 1944 represent one of the largest recorded international transfers and contributed significantly to financing the overall German war effort. Using a neoclassical growth model that incorporates essential features of the...

The post-World War II reconstruction of Western Europe was one of the greatest economic policy and foreign policy successes of this century. "Folk wisdom" assigns a major role in successful reconstruction to the Marshall Plan: the program that transferred some $13 billion to Europe in the years...

Lesotho and other least developed African countries responded impressively to the preferences they were granted under the African Growth and Opportunities Act with a rapid increase in their clothing exports to the US. But this performance has not been accompanied by some of the more dynamic...

Employment growth could reduce violence during civil conflicts. To determine if increased employment affects violence we analyzed varying employment in development programs run by different US military divisions in Iraqi districts. Employment levels vary with funding periods and the military...
