THESIS ABSTRACT Essay 1. The extent of cooperation in R&D and optimal antitrust legislation (Job market paper)The thesis consists of two related papers. I examine R&D cooperation in a context where the government sets rules on the extent of firm cooperation (in R&D or in both R&D and production) and firms make non-contractible investments in acquiring specific knowledge The basic theoretical point of difference in my work is that a firm finds it easier (i.e. less costly) to acquire knowledge in areas closer to his or her own existing specialty. The model is a non-cooperative game and I look at Pareto-dominant, symmetric subgame perfect equilibria. The nature of equilibrium depends on two parameters, one reflecting the cost of investment and another reflecting firms' market power in the goods market. The goods market is specified in two cases: firms compete in one market or they compete in two separated markets. Both specifications of the model lead to the same main results: If the cost of research is high, then government does not restrict cooperation to increase the probability of a successful innovation even though anti-competitive effects in the goods market arise. If the cost of the research project is neither high nor low and firms have sufficient market power, then government outlaws cooperation in production to stimulate cooperation only in R&D. This eliminates both duplication of research efforts and anti-competitive effects. If the cost of research is low, then cooperation only in R&D without cooperation in production is not sustainable and government forbids all types of cooperation because anticompetitive effects are dominant. The antitrust policy appears to be limited in achieving equilibria in which firms cooperate only in R&D but compete in production. Raising taxes in the goods market may be a useful tool to increase both social welfare and firms' profits because it increases effective cost of acquiring specific knowledge, making deviations from cooperative agreements unprofitable. This analysis also shows that because of strategic reasons the problem of the duplication of research efforts may still remain unsolved even when firms cooperate. The results, which I obtained, may explain some empirical puzzles and can be valuable for implementation of antitrust legislation.
