Strategic behaviour of firms in a duopoly and the impact of extending the patenting period

Tapan Biswas and Jolian McHardy

No 2010014, Working Papers from The University of Sheffield, Department of Economics

Abstract: This paper deals with strategic behaviour of firms in a duopoly, subsequent to the claim by one firm that it has reduced the unit cost of production. A variety of possible strategic equilibria are discussed in the context of a duopoly game between a multinational and a local firm. In the context of an extended uniform period of patenting, as finally agreed in the Uruguay round (1994), firms have increased incentive to take patents. In the presence of cost differences, the act of taking process-patents has implications for the equilibrium output strategies of the duopoly firms and sometimes may have a negative overall welfare effect for the local producer and consumers.
