We review some of the most significant issues and results on the economic effects of genetically modified (GM) product innovation, with emphasis on the question of GM labeling and the need for costly segregation and identity preservation activities. The analysis is organized around an explicit...

We build a partial-equilibrium, two-country model to analyze some implications of the introduction of genetically modified (GM) products. In the model, innovators hold proprietary rights on the new technology, whereas farmers are (competitive) adopters; some consumers deem food produced from GM...

We develop a new partial equilibrium, four-region world trade model for the soybean complex comprising soybeans, soybean oil, and soybean meal. In the model, some consumers view genetically modified Roundup Ready (RR) soybeans and products as weakly inferior to conventional ones; the RR seed is...

Evaluating the possible benefits of the introduction of genetically modified (GM) crops must address the issue of consumer resistance as well as the complex regulation that has ensued. In the European Union (EU) this regulation envisions the "co-existence" of GM food with conventional and...

This paper analyzes economic issues that arise in devising a credible and enforceable system of identity preservation and labeling for genetically modified (GM) and non-GM products. The model represents three stages in the supply chain: farm production, marketing handlers, and final users. The...
