We show that a two-part tariff licensing contract is always optimal to the insider patentee in spatial models irrespective of the size of the innovation or any pre-innovation cost asymmetries. The result provides a simple justification of the prevalence of two-part tariff licensing contracts in...

We analyze the capacity choice of firms under demand uncertainty in a mixed duopoly market consisting of one private firm and one public firm. We define a two-stage game where firms choose capacity in the first stage without knowing which state of Nature is going to be realized, and output in...

We consider a game of endogenous timing of sequential choice of capacity and quantity with observable delay in a mixed duopoly and a private duopoly. In mixed duopoly, we find that a simultaneous play at the capacity stage or at the quantity stage can never be supported as subgame perfect Nash...

We analyze the capacity choice of firms under demand uncertainty in a mixed duopoly market consisting of one private firm and one public firm. We define a two-stage game where firms choose capacity in the first stage without knowing which state of Nature is going to be realized, and output in...

We analyze the capacity choice of firms under different time structures in a mixed oligopoly market, in which firms decide not only production quantities but also capacity scales. We show that the public firm never chooses excess capacity, while the private firm never chooses under capacity...

In this paper, we address the issue of illegal copying or counterfeiting of the original product and Intellectual Property Rights (IPR) protections. The original product developer makes costly investment to deter piracy in a given regime of IPR protection. In the presence of a commercial pirate,...

The purpose of this paper is to study the impact of firm ownership in a differentiated industry. We find there is no effect on product differentiation and welfare due to ownership ratio change between private and state so long as the private (state) ownership in a partially state-owned firm...

We show that a two-part tariff licensing contract is always optimal to the insider patentee in spatial models irrespective of the size of the innovation or any pre-innovation cost asymmetries. The result provides a simple justification of the prevalence of two-part tariff licensing contracts in...

We consider a game of endogenous timing of sequential choice of capacity and quantity with observable delay in a mixed duopoly and a private duopoly under two possible time structures. In mixed duopoly, we find that a simultaneous play at the capacity stage or at the quantity stage can never be...
