A Macroeconomic Model of Imperfect Competition with Patent Licensing

Abstract

Abstract This paper sets up an imperfectly competitive macroeconomic model that features the strategic interaction between the patent-holding firm and licensees, and uses it to analyze the relevant macro-variables under various licensing arrangements. Some main findings emerge from the analysis. First, the equilibrium aggregate output and aggregate consumption under fixed-fee and royalty licensing regimes are always greater than those under the no licensing regime. Moreover, the equilibrium aggregate output and consumption under the fixed-fee licensing regime are always greater than those under the royalty licensing regime. Second, with the higher (lower) technology level the patent holder prefers the fixed-fee (royalty) contract. Third, welfare could be improved through technology transfer, and the level of welfare under the fixed-fee licensing regime is higher than that under the royalty licensing regime. Lastly, this paper discusses some extensions of the baseline model.
