Article
Positive and negative spillovers from private activities onto aggregate economic outcomes are empirically significant. How might politics interact with private investment incentives and their externalities? Our theory connects politics to policies which distort private spillovers. This has implications for empirical identification. In our model, fo...

We analyze the setting of access prices for a bottleneck facility where the facility owner also competes in the deregulated downstream market. We consider a continuum of market structures from Cournot to Bertrand. These market structures are fully characterized by a single parameter representing the intensity of competition. We first show how the e...

This paper examines a simple model of strategic interactions among firms that face at least some of the same rivals in two related markets (for goods 1 and 2). It shows that when firms compete in quantity, market prices increase as the degree of multi-market contact increases. However, the welfare consequences of multi-market contact are more compl...

We study inventors' strategic licensing behaviour when there are two generations of technology. The innovations are sequential, with the second invention built on the first. We show that if the market size is large and if the second innovation is relatively significant, the early inventor licenses by royalty and the second-generation inventor licen...
Article
In this paper we consider a model of duopoly with differentiated products to examine the welfare effects of a merger between two asymmetric firms. We find that, for quantity competition, the parameter range for welfare-enhancing merger widens if the products are closer substitutes. On the other hand, mergers are never welfare enhancing in this sett...

We examine a two-sector model characterized by monopoly provision in market 1 and perfect competition in market 2. We follow the set up in Martin (1999), but we consider the case where goods 1 and 2 can be either substitutes or complements. With this framework, we analyse the profit sacrifice required if the monopolist offers a bundle consisting of...
Article
This paper analyses R&D competition among firms with incomplete information. In a stochastic R&D game, firms possess private information regarding their R&D progress. They can only observe the rival's R&D investments, but not its actual R&D position, R&D investments thus carry both investment and signalling effects. In this two-period model. there...
