We show that the presumed incompatibility of R&D and competition in Spence (1984) is not fundamental, but hinges on a critical modeling choice. Specifically, we show that for a widely used class of R&D technology, that is, the functional form mapping R&D effort into cost reduction, the...

We characterize asymmetric equilibria in two-stage process innovation games and show that they are prevalent in the different models of R&D technology considered in the literature. Indeed, cooperation in R&D may be accompanied by high concentration in the product market. We show that while such...

We analyze simultaneous discrete public good games with incomplete information and continuous contributions. We consider contribution and subscription games. We show that every equilibrium is inefficient. We also provide a sufficient condition for 'contributing zero' to be the unique equilibrium...
