We consider a duopoly competing in quantity, where firms can invest in both innovative and absorptive R&D to reduce their unit production cost, and where they benefit from free R&D spillovers between them. We analyze the case where firms act non cooperatively and the case where they cooperate by...

We consider a symmetric model composed of two countries and a firm in each country. Firms produce the same good by means of a polluting technology that uses fossil energy. However, these firms can adopt a clean technology that uses a renewable energy and that has a lower unit cost. Surprisingly,...

We develop a three stage game model composed of a regulator and two firms. These firms compete on the same market where they offer the same homogeneous good, and can invest in R&D to lower their emission/output ratio. By means of a tax per-unit of pollution and a subsidy per-unit of R&D level,...

The impact of the investment in absorptive capacity on transboundary pollution is studied by considering two countries each of them regulating a firm. Firms can invest in original research and in absorptive research to lower their pollution intensity. The absorptive research enables a firm to...

We consider a model consisting of a monopolistic firm producing a certain good with pollution. This firm can adopt a cleaner technology within a finite time by incurring an investment cost decreasing exponentially with the adoption date. At each period of time, the firm is regulated by an...
