Using a unique data set from the multistate Peanut Variety and Quality Evaluation (PVQE) program, we quantify the economic impact of projected warming on revenue of Virginia-type peanuts, for which grade and kernel size are important determinants of price. In contrast to studies for other crops, the impacts of warmer temperatures on yield and quality are symmetric and negative, resulting in acutely depressed farm revenues. Our model predicts a roughly 11% decline in revenue under warming of 1textdegree C. Gains in yield and quality from breeding could offset revenue losses under moderate warming up to 1textdegree C but are unlikely to sustain farm revenues under more extreme changes in temperature.

Theory of the firm suggests that optimal production levels decrease as output price becomes random. Firms operating in industries with long production lags are also exposed to input price uncertainty. This paper provides a novel decision-theoretic model in the presence of both input and output price uncertainty and uses U.S. beef sector data to test theoretical propositions concerning firm behavior. Our findings confirm that, in a two-stage production, the introduction of input price uncertainty leads to increased use of the input and an increased level of output in stage one and a decreased level of output in stage two.
