This paper presents asymptotic theory and Monte-Carlo simulations comparing maximum-likelihood bivariate probit and linear instrumental variables estimators of treatment effects in models with a binary endogenous treatment and binary outcome. The three main contributions of the paper are (a)...

With an estimated 115 million children not attending primary school in the developing world, increasing access to education is critical. Resource constraints limit the effectiveness of demand-based subsidies. This paper focuses on the importance of a supply-side factor -- the availability of...

Winning "hearts and minds" in the Muslim world is an explicitly acknowledged aim of U.S. foreign policy and increasingly, bilateral foreign aid is recognized as a vehicle towards this end. The authors examine the effect of aid from foreign organizations and on-the-ground presence of foreigners...

Evaluations of educational programs commonly assume that what children learn persists over time. The authors compare learning in Pakistani public and private schools using dynamic panel methods that account for three key empirical challenges to widely used value-added models: imperfect...

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...

Measuring the poverty and distributional impact of the global crisis for developing countries is not easy, given the multiple channels of impact and the limited availability of real-time data. Commonly-used approaches are of limited use in addressing questions like who are being affected by the...

As the financial crisis has spread through the world, the lack of real-time data has made it difficult to track its impact in developing countries. This paper uses a micro-simulation approach to assess the poverty and distributional effects of the crisis in the Philippines. The authors find...
