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...

In patent race models, firms' noncooperatively chosen research projects typically display too much correlation. But when there are multiple intellectual property rights protection instruments, we find that the paths chosen in an R&D race can move towards the social optimum.

This paper studies how the strength of intellectual property rights (IPRs) affects investments in biological innovations when the value of an innovation is stochastically reduced to zero because of the evolution of pest resistance. We frame the problem as a research and development (R&D)...
