Outline of Final Research Achievements

Economists often use what is called a patent race model in order to analyse a mechanism of technical progress. In this model, firms invest in research and development. In the end, a single firm succeeds in R&D and earn profits protected by patents. On the other hand, heterogeneity of R&D firms was not explicitly considered in the precursory studies. This research project complements the literature by introducing R&D firm heterogeneity into a patent race model in an explicit and tractable way. By so doing, new results have been established. For example, subsidies to R&D expenditure induce relatively low productivity firms to exit a patent race, and "elite" firms with relatively high productivity remain in the race, leading to an increase in overall R&D expenditure.
