摘要：We assess patent policies where R&D aims at higher quality and the firms engage in strategic behavior.The innovation realized in one period affects the cost of realizing innovations in subsequent periods.The two firms compete in prices,and only one can innovate in each period.We compare the optimal innovation pattern to the second best innovation pattern,involving strategic behavior.Both are superior to the innovation pattern realized in an unregulated market.The market performance can be improved through the introduction of patent protection,and we characterize an optimal protection policy in the form of novelty requirements.
