How will global climate change affect the prevalence of tropical diseases? In general, warmer temperatures will expand the areas in which these diseases are endemic. However, if households can take actions to protect themselves from disease—such as purchasing bednets or insecticidal...

This article describes the data collection and use of data for the computation of rankings within RePEc (Research Papers in Economics). This encompasses the determination of impact factors for journals and working paper series, as well as the ranking of authors, institutions, and geographic...

This chapter describes the impact of national agricultural research systems on the unfolding of the Green Revolution in four regions: Asia, Latin America, the Middle East and North Africa, and Sub-Saharan Africa. Although international institutions contributed much of the research that led to...

According to national accounts data, value added per worker is much higher in the nonagricultural sector than in agriculture in the typical country, particularly in developing countries. Taken at face value, this “agricultural productivity gap†suggests that labor is greatly...

This paper explores the extent to which migration-related capital flows can explain the variation in investment rates and current and capital account imbalances in OECD countries. We begin with a general equilibrium model of a small open economy in which migration is exogenous. Migrants must be...

The Lewis model has remained, for more than half a century, one of the dominant theories of development economics. This paper argues that the power of the model lies in the simplicity of its central insight: that poor countries contain enclaves of economic activity just as rich countries contain...

Recent studies argue that cross-country labor productivity differences are much larger in agriculture than in the aggregate. We reexamine the agricultural productivity data underlying this conclusion using new evidence from disaggregate sources. We find that for the world's staple...

According to national accounts data, value added per worker is much higher in the non-agricultural sector than in agriculture in the typical country, and particularly so in developing countries. Taken at face value, this "agricultural productivity gap" suggests that labor is greatly misallocated...
