We investigate the relationship between market concentration and industry innovative effort within a familiar two-stage model of R&D race in which firms compete à la Cournot in the product market. With the help of numerical simulations, we show that such a setting is rich enough to generate...

We want to take a differential game approach with price dynamics to conduct an investigation into the consequences of horizontal merger of firms where the demand function is nonlinear. We take into consideration the open-loop equilibrium. We show that in relation to the fact that the demand is...

We consider a market for vertically differentiated goods where firms enter over time, after having developed innovations characterised by different quality levels. We show that patent height and length interact to determine the ultimate emergence of duopoly. In general, imposing quality...

We revisit Maxwell's (1998) analysis to show that MQS regulation has no effects on the high-quality firm's incentive to adopt a more efficient technology in a vertically differentiated duopoly with fixed costs of quality improvement and full market coverage

We extend a well known differential oligopoly game to encompass the possibility for production to generate a negative environmental externality, regulated through Pigouvian taxation and price caps. We show that, if the price cap is set so as to fix the tolerable maximum amount of emissions, the...

I characterise the subgame perfect equilibrium of a differential market game with hyperbolic demand where firms are quantity-setters and accumulate capacity over time à la Ramsey. I show that the open-loop solution is subgame perfect. Then, I analyse the feasibility of horizontal mergers, and...
