We present a new framework to identify demand and supply elasticities of agricultural commodities using yield shocks - deviations from a time trend of output per area, which are predominantly caused by weather fluctuations. Demand is identified using current-period shocks that give rise to...

Crop diseases and how they are managed can have a large impact on agricultural productivity. This paper discusses the effects on agricultural productivity of Verticillium dahliae, a soil borne fungus that is introduced to the soil via infested spinach seeds and that causes subsequent lettuce...

This research explores the origins of the distribution of time preference across regions. It advances the hypothesis, and establishes empirically, that geographical variations in natural land productivity and their impact on the return to agricultural investment have had a persistent effect on...

A growing body of economics research projects the effects of global climate change on economic outcomes. Climate scientists often criticize these articles because nearly all ignore the well-established uncertainty in future temperature and rainfall changes, and therefore appear likely to have...

We examine the supply-side and demand-side determinants of global bilateral food aid shipments between 1971 and 2008. First, we find that domestic food production in developing countries is negatively correlated with subsequent food aid receipts, suggesting that food aid receipt is partly driven...

Scholars differ on whether Federal Reserve intervention mitigated banking panics during the Great Depression and in recent years. The last panic prior to the Depression sheds light on this debate. In April 1929, a fruit fly infestation in Florida forced the U.S. government to quarantine fruit...

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...

Most American financial crises of the postbellum gold-standard era were caused by fluctuations in the cotton harvest due to exogenous factors such as weather. The transmission channel ran through export revenues and financial markets under the pre-1914 monetary regime. A poor cotton harvest...

We investigate the link between agricultural productivity and net migration in the United States using a county-level panel for the most recent period of 1970-2009. In rural counties of the Corn Belt, we find a statistically significant relationship between changes in net outmigration and...
