We investigate the relationship between competition and innovation using a dynamic oligopoly model that endogenizes … both the long-run innovation rate and market structure. We use the model to examine how various determinants of competition …

Previous theoretical researches show that learning from good performers yields intense competition and results in the … useful strategic tool to mitigate competition. We introduce an evolutionary (learning) game into a duopoly model with product … even when firms have an opportunity to differentiate themselves through product differentiation and to mitigate competition …

We consider a dynamic competition game among three players, where each player can vary the extent of his competition on … a per-rival basis. We call such competition targeted. We show that if the players are myopic, the weaker players … competition can be applied to competition between firms or political parties, or to warfare …

and relaxed competition. In its theory, firms compete over an infinite-horizon and discount the future so that relaxed … competition is feasible in equilibrium. However, firms face strategic uncertainty, so this equilibrium hinges on their beliefs … about their rivals' pursuit of relaxed competition. In this setting, certain beliefs can support differentiation and …

We develop a theoretical model to analyse the e ect of competition on the conflict of interest arising from the issuer … inflate ratings under competition, resulting in lower expected welfare. These results do not depend on the presence of ratings … suggest that ongoing regulatory initiatives aimed at increasing competition in the ratings industry may reduce overall welfare …
