An important discussion in recent years is the introduction of product patentsand the abolition of process patents. In a model with endogenous number of innovatingfirms, we show that whether product patent increases R&D is ambiguous, and depends onthe type of market demand and the cost of R&D....

We show the effects of Bertrand and Cournot competition on R&D investmentand social welfare in a duopoly with R&D competition where success in R&D isprobabilistic. We show that R&D investments are higher under Bertrand (Cournot)competition when R&D productivities are sufficiently low (high), and...

In a vertically separated industry, where the input suppliers have significantmarket power, not only entry but also the markets (upstream or downstream) withentry possibilities might be a concern to the policy makers. While ‘entry in thedownstream market only’ always increases welfare,...

The literature on technology licensing has ignored the importance ofmarket power of the input supplier. In this paper we examine the incentive forlicensing in the downstream industry when the firms in the upstream industry havemarket power. We show that licensing in the downstream industry is...

We consider the effects of product market cooperation on R&Dinvestment, profits, consumer surplus and welfare. We show that though R&Dinvestment, consumer surplus and social welfare may be higher or lower underproduct market cooperation than product market competition, industry profit isalways...

This paper compares Bertrand and Cournot equilibria in a horizontallydifferentiated duopoly market with non-tournament R&D competition. We consider thatsuccess in R&D is uncertain. We show that whether firms invest more under Cournotcompetition or Bertrand competition is ambiguous and depends on...

This paper provides a framework with which to model one of the key links between universities andindustry – the undertaking of applied research. We assume that the fundamental objective of universities isto undertake fundamental research and that they receive public funding to do so....

We introduce pollution, as a by-product of production, into a non-tournament model of R&Dwith spillovers. Technology policy takes the form of either R&D subsidisation or pre-competitiveR&D cooperation. We show that, when the emissions tax is exogenous, the optimal R&Dsubsidy can be negative,...
