The social and economic consequences of poor mental health in the developing world are presumed to be significant, yet are largely under-researched. The authors argue that mental health modules can be meaningfully added to multi-purpose household surveys in developing countries, and used to...

The relationship between poverty and mental health has received considerable attention in the recent literature. However, the associations presented in existing studies typically rely on limited samples of individuals and on proxy indicators for poverty such as education, the lack of tap water,...

Using a database of 76,046 empirical economics papers published between 1985 and 2004 in the top 202 economics journals, the authors report two associations. First, per-capita research output on a given country increases with the country's per capita gross domestic product (GDP). Regressions...

During the past decade, the use of conditional cash transfers to increase investment in human capital has generated considerable excitement in both research and policy forums. Such schemes are being increasingly adopted in a number of contexts and countries to improve outcomes in health,...

Using a database of 76,046 empirical economics papers published between 1985 and 2005, we report two associations. First, research output on a given country increases with the country's population and wealth, yielding a strong correlation between per-capita research output and per-capita GDP....

Standard models of investment predict that credit-constrained firms should grow rapidly when given additional capital, and that how this capital is provided should not affect decisions to invest in the business or consume the capital. The authors randomly gave cash and in-kind grants to male-...

Purchasing power parity (PPP) exchange rates are extensively used by researchers and by policymakers. This paper proposes and implements a new methodology for calculating PPPs using information on unit values from household surveys. Although unit values are not identical to prices, they have...

The human consequences of the current global financial crisis for the developing world are presumed to be severe yet few studies have quantified such impact. The authors estimate the additional number of infant deaths in sub-Saharan Africa likely due to the crisis and discuss possible mitigation...

Agricultural and other physically demanding sectors are important sources of growth in developing countries but prevalent diseases such as malaria adversely impact the productivity, labor supply, and choice of job tasks among workers by reducing physical capacity. This study identifies the...
