This article deals with the specification of a locally flexible and theory-consistent system of mixed demand functions, a framework that allows for a rich set of possibilities about what is assumed as exogenous in a demand model. A coherent mixed demand system is derived by using the restricted...

The extensive adoption of genetically engineered (GE) varieties in U.S. agriculture has dramatically changed the patterns of pesticide use. How this process ultimately affects environmental risk remains an open question. Previous studies have typically relied on aggregate trends to infer the...

A partial equilibrium four-region world trade model for the soybean complex is developed in which Roundup Ready (RR) products are weakly inferior substitutes to conventional ones, RR seeds are priced at a premium, and costly segregation is necessary to separate conventional and biotech products....

Food system regulators often decide whether to ban existing practices or approve new technologies without conclusive scientific evidence on possible damage and knowing that resolution is likely in the future. In a model with three decision points and stochastic resolution of uncertainty, we...

We employ an open economy general equilibrium model to investigate the effects of governmentenergy policy, with an emphasis on corn-based ethanol, on the U.S. economy. The modelspecification incorporates world and domestic markets, assumes pollution costs from fuelconsumption, and allows...

Research and Development (R&D) and innovation are crucial features of the seed industry. To supportlarge R&D investments by the private sector, strong intellectual property rights, such as patents, arenecessary. The exclusivity granted by patents naturally creates market power positions and...

We develop a reputation model to study the concurrent use of trademarks and certification for foodproducts with a regional identity, known as geographical indications (GIs). The model extendsShapiro’s (1983) approach to modeling reputation to a situation in which two technologies for...
