We were asked to discuss specific methodological approaches to evaluating three hypothetical interventions. This article uses this forum to discuss three misperceptions about randomized trials. First, nobody argues that randomized trials are appropriate in all settings, and for all questions....

There is little doubt that technology change, both in terms of its process and quality dimensions, represents the principal driving force to explain comparative economic performance at both micro and macro levels. This paper examines the sources of technology change and the impediments to the...

This paper reviews the literature on the impact of ethnic diversity on economic development. Ethnically polarized societies are less likely to agree on the provision of public goods and more likely to engage in rent seeking activities providing lower levels of social capital. Initial conditions...

The long-run price elasticity of demand for credit is a key parameter for intertemporal modeling, policy levers, and lending practice. We use randomized interest rates, offered across 80 regions by Mexico’s largest microlender, to identify a 29-month dollars-borrowed elasticity of -1.9. This...

Vertical decentralization, either at the deconcentration, delegation or, more rarely, the devolution level, has been instituted in most countries of Sub-Saharan Africa. It usually has the effect of increasing the quantity as well as the quality, in terms of health and education, of public goods....

This paper reviews the literature on the impact of ethnic diversity on economic development. Ethnically polarized societies are less likely to agree on the provision of public goods and more likely to engage in rent seeking activities providing lower levels of social capital. Initial conditions...

Recent literature has contrasted Human Development, described as the ultimate goal of the development process, with economic growth, described as an imperfect proxy for more general welfare, or as a means toward enhanced human development. This debate has broadened the definitions and goals of...

This paper explores the links between economic growth and human development, identifying two chains, one from economic growth to human development, the other, from human development to economic growth. The importance of various links in each chain are explored empirically with the help of...
