We model the interplay between capital accumulation for production and environmental externalities in a differential oligopoly game with Ramsey dynamics. The external effect is determined, alternatively, by sales or production. While the externality does not affect the behaviour of...

We reassess the respective gains from R&D cooperation and competition in a Cournot duopoly where firms adopt a concave cost-reducing R&D technology. Cooperation, in the form of either a cartel or a joint venture, is always profitable for firms and, contrary to the previous literature on the same...
