While most contemporary historians agree that the use of debt peonage as a coercive labor contract in Mexico was not widespread, scholars still concur that it was important and pervasive in Yucatan state during the henequen boom of the late 19th and early 20th centuries. The henequen boom...

This research report makes the following claims: 1] There was not an unambiguous economic advantage of hybrid corn over the open-pollinated varieties in 1936. 2] The early adoption of hybrid corn before 1937 can be better explained by a sustained propaganda campaign conducted by the U.S....

Much of Africa has not yet gone through a quot;demographic transitionquot; to reduced mortality and fertility rates. The fact that the continent's countries remain mired in a Malthusian crisis of high mortality, high fertility, and rapid population growth (with an accompanying state of chronic...

We employ the 1860 Census of Manufactures to study rural antebellum manufacturing in the South and Midwest, and find that manufacturing output per capita was similar across regions in counties specialized in the same agricultural products. The southern deficit in manufactures per capita appears...

We assess the effects of a major land policy change on farm size and agricultural productivity using a quantitative model and micro-level data. We study the 1988 land reform in the Philippines that imposed a ceiling on land holdings, redistributed above-ceiling lands to landless and smallholder...

Standard measures of productivity display enormous dispersion across farms in Africa. Crop yields and input intensities appear to vary greatly, seemingly in conflict with a model of efficient allocation across farms. In this paper, we present a theoretical framework for distinguishing between...

This paper explores the interplay between the biophysical and economic geographies of climate change impacts on agriculture. It does so by bridging the extensive literature on climate impacts on yields and physical productivity in global crop production, with the literature on the economic...

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...

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...

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...
