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 cost-reducing investment in vertically-related oligopolies, where firms may be vertically integrated or separated. Analyzing a standard linear Cournot model, we show that: (i) Integrated firms invest more than separated competitors. (ii) Vertical integration increases own investment...

We investigate how various institutional settings affect a network provider’s incentives to invest in infrastructure quality. Under reasonable assumptions on demand, investment incentives turn out to be smaller under vertical separation than under vertical integration, though we also provide...

The paper characterizes the mixed-strategy equilibria in all-pay auctions with endogenous prizes that depend positively on own effort and negatively on the effort of competitors. Such auctions arise naturally in the context of investment games, lobbying games, and promotion tournaments. We also...

The paper analyzes the effects of more intense competition on firms’ incentives to invest in process innovations. We carry out experiments based on two-stage games, where R&D investment choices are followed by product market competition. As predicted by theory, an increase in the number of...
