Traditional oligopoly models hold that firms compete in the same strategic variable, output
(Cournot) or price (Bertrand). Alternatively, a hybrid model allows some firms to compete in …

This paper demonstrates that relative-performance based strategic managerial delegation
does not lead to the equivalence of Bertrand and Cournot equilibria in the presence of …

This article augments d'Aspremont and Jacquemin's [1988.“Cooperative and
Noncooperative R&D in Duopoly with Spillovers.” American Economic Review 78: 1133 …

The R&D literature framed in a strategic context shows two unpleasant outcomes for the
public goods nature of knowledge: 1) the private R&D activity results in under-investment …

This paper examines the implication of the nature of competition in a market with network
externalities on strategic investment in process R&D by firms. It shows that network …

Conventional wisdom is that collusion between firms will be destabilized when they produce
closer substitutes of products. We show that, in the presence of strong network externalities …

that if network goods are fully incompatible, entry is socially insufficient as long as the entry …

We study whether a quantity or a price contract is chosen at equilibrium by one integrated
firm and its retail competitor in a differentiated duopoly. Using a similar vertical structure …

This paper analyzes implications of network compatibility and competition on process
innovation in differentiated network goods duopoly. It shows that firms' R&D investments are …

This study examines the endogenous choice of strategic contracts in a duopoly composed of
firms that produce goods with network externalities with some sort of compatibility. We adopt …
