Game theory is used to examine the incentives for private firms to fund applied research to improve differentiated crop varieties sold to compete with a public generic variety. We distinguish between applied research, modeled as a stochastic search process, and basic research, which improves...

An incumbent export subsidy will affect the size and distribution of gains from bilateral trade liberalization but, in theory, may still permit increased trade volume and mutual benefits from freer trade. These points are illustrated using the case of Canada-U.S. durum wheat trade, which grew...

Annual data for forty-eight states are used to account for changes in the composition of input and output aggregates over space and time, and thereby to obtain new evidence on changes in inputs, outputs, and productivity in U.S. agriculture. The measures change significantly when we use...

Reported rates of return to agricultural R&D are generally high, but they are likely to be biased, particularly because of attribution problems-mismatching research benefits with costs. The importance of attribution biases is illustrated here with new evidence for Brazil. During 1981-2003,...

Many commentators claim that farm subsidies have contributed significantly to the "obesity epidemic" by making fattening foods relatively cheap and abundant and, symmetrically, that taxing "unhealthy" commodities or subsidizing "healthy" commodities would contribute to reducing obesity rates. In...
