We introduce pollution, as a by-product of production, into a non-tournament model of R&D with spillovers. Technology policy takes the form of either R&D subsidisation or pre-competitive R&D cooperation. We show that, when the emissions tax is exogenous, the optimal R&D subsidy can be negative,...

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...

We propose a model of environmental overcompliance in a duopoly setting where consumers are environmentally concerned and may patronise the product they buy, firms set their green investment to abate the impact of productivity on pollution and a government sets the environmental standard with...

In this paper we analyse a setup where consumers are heterogeneous in the perception of environmental quality. The equilibrium is verified in a setting with horizontal and vertical (green) differentiation. Profits are increasing in the misperception of quality, while, the investment in green...
