This paper endogenises the extent of intra-sectoral competition in a multi-sectoral model of oligopoly in general equilibrium. Firms choose capacity followed by prices. If the benefits of capacity investment in a given sector are below a threshold level, the sector exhibits Bertrand behaviour,...

We introduce the concept of cooperative substitutes and complements, and use it to throw light on the conditions for a research joint venture to choose equal levels of R&D by all member firms. We show that the second-order conditions for a symmetric optimum take a particularly simple form,...

In this paper we discuss the incentives of a welfare maximizing government to implement strategic trade policy when there is, on the one hand, uncertainty about the relevant market information (like the type of competition, demand function, cost function, etc.), but, on the other hand, the...
