We study how network externalities affect research and development (R&D) investments by a non-cooperative duopoly that offers compatible products. We find that multiple R&D equilibria may arise when network externalities are non linear in the number of consumers. The lowest R&D equilibrium...

It is proved that the irrelevance result of Poyago-Theotoky can be extended from the linear-quadratic case to general inverse demand and cost functions. Hence, as long as firms are profitable at the first-best, the optimal subsidy decentralizes it in mixed oligopoly irrespecitve of whether the...

Licensing a new technology implies introducing competition into the market. This has a negative effect on the profit of the incumbent if the demand remains unchanged. However, because of the novel content of an innovation, consumers may have different perceptions of the value of a good depending...

White (1996), Poyago-Theotoky (2001) and Myles (2002) prove that in the mixed oligopoly the optimal subsidy, equilibrium output level, all firms' profits and social welfare are identical irrespective of whether the public firm maximizes welfare or profit and moves simultaneously with private...
