We examine the economic impact of high-yielding crop varieties (HYVs) in developing countries 1960-2000. We use time variation in the development and diffusion of HYVs of 10 major crops, spatial variation in agro-climatically suitability for growing them, and a differences-in-differences...

India started the implementation of a rural public works program in 2006, covering all districts of the country within three years. The program quarantees 100 days of employment per year at minimum wage to each rural household on demand, with the goal of reducing joblessness and poverty. We...

To estimate the local effect of establishing land grant colleges, I compare locations that receive a land grant college to “runner-up” counties that were in contention to receive the land grant but did not for as-good-as-random reasons. I find that establishing a land grant college causes an...

Performance pay for tax collectors has the potential to raise revenues, but might come at a cost if taxpayers face undue pressure from collectors. We report the first large-scale field experiment on these issues, where we experimentally allocated 482 property tax units in Punjab, Pakistan into...

In this paper, a structural gravity model is presented which features intra-sector heterogeneity in agricultural productivity systematically linked to land and climate characteristics. The “systematic heterogeneity” (SH) gravity model predicts that countries with similar land and climate...

This study investigates the economic consequences of parental leave mandates using data for 16 European countries over the 1969 through 1988 period. Since women use virtually all of the family leave in most nations, men constitute a reasonable comparison group and the natural experiment in most...

In 2004, the European Union admitted 10 new countries, and wages in these countries were generally well below the levels in the existing member countries. Citizens of these newly-admitted countries were subsequently free to take jobs anywhere in the EU, and many did so. In 2015, a large number...
