Starting in the 1930s, commercial hybrid corn seeds rapidly replaced the once predominant open-pollinated varieties planted by farmers. By the mid-1950s almost all corn grown in the United States was of hybrid varieties. Observers have argued that the drought tolerant qualities of these hybrids...

We examine the distributional consequences of trade using the New World Grain Invasion that occurred in the second half of the 19th century. We use a newly-created dataset on population, employment by sector, property values, and poor law transfers for over 10,000 parishes in England and Wales...

Crop production is subject to supply shocks, and both expected and realized outputs as well as output prices are unknown when inputs are chosen. The process by which producers form expectations is difficult to model, especially when working with aggregate data. We present a necessary and...

If the extension of federal crop insurance programs to cover fruit and vegetable production has affected either producer or consumer welfare, then we would expect to see this reflected in output and prices. Exploiting variation in the timing of program introduction in different locations for...

We estimate the factors determining specialization of crop choice at the level of individual fields, distinguishing between the role of natural advantage (soil characteristics) and economies of density (scale economies achieved when farmers plant neighboring fields with the same crop). Using...

2] The early adoption of hybrid corn before 1937 can be better explained by a sustained propaganda campaign conducted by the U.S. Department of Agriculture at the direction of the Secretary of Agriculture, Henry Agard Wallace. The Department's campaign echoed that of the commercial seed...

We investigate how historical patterns of primary production influenced development across local economies in Argentina. Our identification strategy exploits exogenous variation in the composition of primary production induced by climatic features. We find that locations specializing in ranching...

Arid regions of Africa are expanding by thousands of square kilometers a year, potentially disturbing pastoral routes that have been forged over a long period of time. This disturbance is often said to explain why "herder-farmer" conflicts have erupted in recent years, as pastoralists and...

Particulate matter significantly reduces life expectancy in India. We use a randomized controlled trial in the Indian state of Punjab to evaluate the effectiveness of conditional cash transfers (also known as payments for ecosystem services, or PES) in reducing crop residue burning, which is a...
