The World Health Organization (WHO) reports that malaria, a parasitic disease transmitted by mosquitoes, causes over 300 million episodes of “acute illness" and more than one million deaths annually. Most of the deaths occur in poor countries of the tropics, and especially sub-Saharan Africa....

This research advances and empirically establishes the hypothesis that, in the course of the prehistoric exodus of Homo sapiens out of Africa, variation in migratory distance to various settlements across the globe affected genetic diversity and has had a persistent hump-shaped effect on...

The large current account and capital account imbalances among OECD countries continue to attract attention among policy makers and researchers. This paper explores the extent to which migration-related capital flows can explain the movements and magnitudes of current and capital account...

This paper examines the fiscal policy options that were available to Latin American countries at the onset of the current global economic crisis. It concludes that most of the major countries in the region possessed the fiscal space (as measured by credible fiscal sustainability and debt...

A longstanding question in economics is why some countries are so much richer than others. Today, for example, income per capita in the world's richest countries is roughly thirty-five times greater than it is in the world's poorest countries. Recent work argues that the proximate cause of the...

We study the impact of global climate change on the prevalence of tropical diseases using a heterogeous agent dynamic general equilibrium model. In our framework, households can take actions (e.g., purchasing bednets or other goods) that provide partial protection from disease. However, these...

Microfinance institutions and other lenders in developing countries rely on the promise of future loans to induce repayment. However, if borrowers expect that others will default, and so loans will no longer be available in the future, then they will default as well. We refer to such contagion...

This paper investigates the impact of workers’ remittances on equilibrium real exchange rates (ERER) in recipient economies. Using a small open economy model, it shows that standard “Dutch Disease” results of appreciation are substantially weakened or even overturned depending on: degree...

Remittance inflows have increased considerably in recent years and are large relative to the size of many recipient economies. The theoretical and empirical effects of remittance inflows on output growth volatility are, however, ambiguous. On the one hand, remittances have been a remarkably...
