Determinants of Agricultural Output: Degree Days, Yields and Implications for Climate Change AgEcon
Schlenker, Wolfram; Hanemann, W. Michael; Fisher, Anthony C..
We link farmland values to climatic, soil, and socioeconomic variables for counties east of the 100th meridian, the historic boundary of agriculture not primarily dependent on irrigation. Degree days, a non-linear transformation of the climatic variables suggested by agronomic experiments as more relevant to crop yield gives an improved fit and increased robustness. Estimated coefficients are consistent with the experimental results. The model is employed to estimate the potential impacts on farmland values for a range of recent warming scenarios. The predictions are very robust and more than 75% of the counties in our sample show a statistically significant effect, ranging from moderate gains to large losses, with losses in the aggregate that can become...

Consumer and Market Responses to Mad-Cow Disease AgEcon
Schlenker, Wolfram; Villas-Boas, Sofia Berto.
We examine how consumers and financial markets in the United States react to two health warnings about mad cow disease: The first discovery of an infected cow in December 2003 as well as health warnings about the potential effects aired in the highly-watched Oprah- Winfrey show seven years earlier. Using a unique UPC-level scanner data set, we find a pronounced and significant reduction in beef sales following the first discovered infection. This effect slowly dissipates over the next three months. Interestingly, no significant impact can be detected in the diary files of the Consumer Expenditure Survey (CES) that has a much smaller sampling frame. However, futures prices show a comparable drop in prices to the scanner data. Contracts with longer maturity...

Resilience, Uncertainty, and the Role of Economics in Ecosystem Management AgEcon
Brozovic, Nicholas; Schlenker, Wolfram.
Many natural systems have the potential to switch between alternative dynamic behaviors. We consider a system with two distinct equations of motion that are separated by a threshold value of the state variable. We show that utility maximization will give a decision making rule that is consistent with ecosystem-based management objectives that aim to reduce the probability that the system crosses the threshold. Moreover, we find that increasing uncertainty (both uncertainty embedded in the natural system and uncertainty of the decision maker about the location of the threshold) can lead to nonmonotonic changes in precaution. Although small increases in uncertainty may at first increase precaution, large enough increases in uncertainty will lead to a...
