We examine the interplay of endogenous vertical integration and costreducing downstream investment in successive oligopoly. We start from a linear Cournot model to motivate our more general reducedform framework. For this general framework, we establish the following main results: First,...

Using a general two-stage framework, this paper gives sufficient conditions for increasing competition to have negative or positive effects on R&D-investment, respectively. Both possibilities arise in plausible situations, even if one uses relatively narrow definitions of increasing competition....

We examine the competitive effects of the vertical integration of gasoline refineries and retailers in the U.S. Adapting the first-order condition approach of static oligopoly games to the analysis of vertically related oligopolies, we develop a novel framework for directly evaluating the...
