Extreme heat is the single best predictor of corn and soybean yields in the United States. While average yields have risen continuously since World War II, we find no evidence that relative tolerance to extreme heat has improved between 1950 and 2005. Climate change forecasts project a sharp...

The Agricultural Adjustment Act (AAA) caused a population shift in the United States in the 1930s. Evaluating the effects of the AAA on the incidence of malaria can therefore offer important lessons regarding the broader consequences of demographic changes. Using a quasi-first difference model...

Between 1928 and 1960 U.S. cotton production witnessed a revolution with average yields roughly tripling while the quality of the crop increased significantly. This paper analyzes the key institutional and scientific developments that facilitated the revolution in biological technologies,...

Patents are the main source of data on innovation, but there are persistent concerns that patents may be a noisy and biased measure. An important challenge arises from unobservable variation in the size of the inventive step that is covered by a patent. The count of later patents that cite a...

This paper estimates the impact of U.S. trade remedy (TR) actions on agricultural trade from 1990 to 2014. Most previous studies of the effects of TR actions have left out agricultural products. We use a four-country oligopolistic trade model to study the impact of TR duties on imports from...

The New Deal increased the amount and breadth of agricultural regulation in the economy, shifting it from providing public goods and transfers to controlling supplies and directing government purchases to raise prices, and created the institutional structure to continue the new regulation long...

While many developing-country policymakers see heavy fertilizer subsidies as critical to raising agricultural productivity, most economists see them as distortionary, regressive, environmentally unsound, and argue that they result in politicized, inefficient distribution of fertilizer supply. We...

This paper investigates the impact of rich-country agricultural support on the poor. Using non-parametric analysis we establish that the majority of poor countries are consistently net importers of food products that are heavily supported by OECD governments. Using a cross-country regression...

U.S. farms, and with them agricultural lending institutions, are currently experiencing their most severe stress since the 1930s. As international trade in farm products has expanded, so has the sensitivity of farm incomes to fluctuations in domestic and world economic conditions. Thus, while...
