We analyze an Open Innovation process in a Cournot duopoly using a differential game approach where knowledge spillovers are endogenously determined via the R&D process. The game produces multiple steady states, allowing for an asymmetric solution where a firm may trade off the R&D investment...

We propose a simple method for characterising analytically the feedback solution of oligopoly games with capital accumulation à la Solow-Swan. As a result, it becomes possible to contrast the feedback equilibrium against the corresponding one generated by open-loop information. Our method...

We investigate the possibility of using public firms to regulate polluting emissions in a Cournot oligopoly where production takes place at constant returns to scale and entails a negative environmental externality. We model the problem as a differential game and investigate (i) the Cournot-Nash...

We examine a duopoly with polluting production where fi rms adopt a form of corporate social responsibility (CSR) to de fine their objective functions. Our analysis focuses on the bearings of CSR on collusion over an in nite horizon, sustained by either grim trigger strategies or optimal...

We build up a differential game to investigate the interplay between the quality of health care and the presence of an evolving disease in a duopoly where patients are heterogeneous along the income dimension. We prove unicity, stability and perfection of the open-loop Nash solution. Moreover,...

This paper examines the stability conditions of the equilibria in a market where profit-maximizing and CSR firms coexist in the presence of an environmental externality. An equilibrium in mixed duopoly is stable for low impact of productivity on pollution and high CSR sensitivity to consumer...

We model a vertically differentiated duopoly with quantity-setting fi rms as an extended game in which firms noncooperatively choose the timing of moves at the quality stage, to show that at the subgame perfect equilibrium sequential play obtains, with the low-quality firm taking the leader's role

We extend the analysis carried out by Valletti (2000) by considering an environmental externality in a vertically differentiated duopoly where firms compete à la Cournot with fixed costs of quality improvement.We show that, if the weight of the external effect is high enough, the resulting...

This paper investigates how CSR firms influence a Cournot oligopoly with pollution. We define as CSR a firm that takes into account not only its profits but also internalises its own share of the externality and is sensitive to consumer surplus. The CSR firm obtains higher profits compared to...

We investigate the feasibility of horizontal mergers in a homogeneous triopoly where firms compete in quantities and production is polluting the environment. We show that the degree of alignment between private and social incentives increases in the intensity of pollution
