We examine the relationship between competition and innovation in an industry where production is polluting and R&D aims to reduce emissions ("green" innovation). We present an n-firm oligopoly where firms compete in quantities and decide their investment in "green" R&D. When environmental...

We revisit the debate on the optimal number of firms in the commons in a differential oligopoly game in which firms are either quantity-or price-setting agents. Production exploits a natural resource and involves a negative externality. We calculate the number of firms maximising industry...

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...
