In the first essay, “A Model of Diffusion of Genetically Modified Crop Technology in Concentrated Agricultural Processing Markets - The Case of Soybeans”, a dynamic model of diffusion of a genetically modified crop technology is developed and simulated. The model accounts for factors specific to agricultural markets, such as oligopsony power of crop processors, grower characteristics, and identity preservation requirements. It is found that market power of crop processors decreases the equilibrium adoption levels and prolongs the diffusion period. Producer uncertainty and perception of the risks associated with planting GM crops increases equilibrium adoption levels but lengthens the diffusion period, and producer heterogeneity with respect to new crop profitability may have different effects on the diffusion process. The second essay is called “Valuation of International Patent Rights for Agricultural Biotechnology”. In it, the choices that biotechnology companies make about marketing different genetically modified (GM) crops in different countries with highly uncertain returns are modeled as a real option problem of the entry decision solved at a micro-level by individual firms. A computational solution to the model produces distributions of entry probabilities that are determined by different market and regulatory environments. These proportions are compared to the actual data on incidences of biotech firms entering foreign markets with different GM crops, and conclusions about the distribution of patent values, returns evolution, and efficiency of local IPR protection are drawn. In the third essay, “Patent Policy Analysis for the Case of Agricultural Biotechnological Innovations”, certain peculiarities of the process of development of agricultural biotechnological innovations are considered, in particular the distinction between an R&D race for an event discovery and subsequent competition for developing the discovery’s marketable applications. A formal model is specified and analyzed with regard to how different patent protection policies affect firms’ R&D strategies and social surplus from innovations. It is found that inclusive scope patent protection encourages more R&D and faster innovation diffusion than additional scope protection, which is superior to length protection. 2003-10-15 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1058818716 http://rave.ohiolink.edu/etdc/view?acc_num=osu1058818716 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
