The United States produces 41% of the world's corn and 38% of the world's soybeans, so any impact on US crop yields will have implications for world food supply. We pair a panel of county-level crop yields in the US with a fine-scale weather data set that incorporates the whole distribution of...

This paper explores the effects of relative food prices on body weight and body fat over time in China. We study a cohort of 15,000 adults from over 200 communities in China, using the longitudinal China Health and Nutrition Survey (1991-2006). While we find that decreases in the price of...

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...

Corn prices increased sharply in the summer of 2012 due to expected production shortfalls in the United States, which produces roughly 40% of the world's corn. A heat wave in July adversely affected corn production. We extend earlier statistical models of county-level corn yields in the Eastern...

This paper explores the relationship between shelf prices and manufacturers' coupons for 25 ready-to-eat breakfast cereals. Contrary to the predictions of static monopoly price discrimination, we find the shelf prices for a particular brand in a particular city are generally lower during periods...

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...

This paper investigates the institutional causes of China's Great Famine. It presents two empirical findings: 1) in 1959, when the famine began, food production was almost three times more than population subsistence needs; and 2) regions with higher per capita food production that year suffered...

This paper seeks to better understand the historical origins of current differences in norms and beliefs about the appropriate role of women in society. We test the hypothesis that traditional agricultural practices influenced the historical gender division of labor and the evolution and...

Many discussions following the 2007/08 food price crisis have revolved around the magnitude of the negative impacts that it may have had on food security worldwide. Analysts have been asked to provide timely assessments, often based on partial data and information. The variety of opinions and...
