We use individual-level data on all security trades, holdings, spending, and income from an online retail bank. We study the effects of an exogenous change in the displayed purchase prices of the mutual funds in individuals’ portfolios. We find that individuals are more likely to sell what we...

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...

Most interpretations of prevalent counterinsurgency theory imply that increasing government services will reduce rebel violence. Empirically, however, development programs and economic activity sometimes yield increased violence. Using new panel data on development spending in Iraq, we show that...

We examine the supply-side and demand-side determinants of global bilateral food aid shipments between 1971 and 2008. First, we find that domestic food production in developing countries is negatively correlated with subsequent food aid receipts, suggesting that food aid receipt is partly driven...

A number of development assistance programs promote community interaction as a means of building social capital. Yet, despite strong theoretical underpinnings, the role of repeat interactions in sustaining cooperation has proven difficult to identify empirically. We provide the first...

This paper shows that general equilibrium effects can partly rationalize the high correlation between saving and investment rates observed in OECD countries. We find that once controlling for general equilibrium effects the saving-retention coefficient remains high in the 70's but decreases...

How well do countries cope with the aftermath of natural disasters? In particular, do international financial flows help buffer countries in the wake of disasters? This paper focuses on hurricanes (one of the most common and destructive types of disasters), and examines the impact of hurricane...

We examine one of the most important and intriguing puzzles in economics: why it is so hard to find a robust effect of aid on the long-term growth of poor countries, even those with good policies. We look for a possible offset to the beneficial effects of aid, using a methodology that exploits...
