We proffer a method to assess the adequacy of expected utility theory (EUT) in empirical studies involving discrete and continuous choices. The method calibrates a utility function to revealed choices and rejects EUT for absurd degrees of implied concavity over the wealth at risk. We find EUT...

Economists frequently focus on correlations between wealth and risk preferences but rarely observe the probabilities needed to test this relationship empirically. These unobserved probabilities are typically estimated via profit or production functions conditioned on wealth correlates, which may...

We develop a model of decision makers' demand for agricultural economic information services. This modeltreats choice of externaldecision-support services as a function of actors' assessment of how alternative investments in information complement their internal competencies. Data from a survey...

A general theory of cross-subsidization due to inframarginal support is developed. Two sources of output distortion are identified: exit deterrence and extramarginal output. Some firms would not be in business without the subsidy. Cost savings due to declining average costs are always greater...

A price discrimination model is proposed to explain why firms provide extraneous information on Internet sites selling agricultural inputs. Whether an informative site is offered depends on price discrimination potential, which depends on how much farmers reveal heterogeneity by Internet...

We show how leakage differs, depending on the biofuel policy and market conditions. Carbon leakage is shown to have two components: a market leakage effect and an emissions savings effect. We also distinguish domestic and international leakage and show how omitting the former like the IPCC does...

Many governments try to stabilize commodity prices based on the widespread belief that households value price stability and that the poor especially benefit from food price stabilization. We derive an exact measure of multivariate price risk aversion and of associated household willingness to...
