We charaterise the socially optimal mix of firms in an oligopoly with both profit-seeking and labour-managed firms. The policy maker faces a twofold externality: (i) production entails the exploitation of a common pool natural resource and (ii) production/consumption pollutes the environment. We...

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...

In this paper we compare two policy instruments that can be adopted to curb carbon emissions. The first is a conventional pollution tax. The second is an environmental campaign aiming to influence consumers to switch to a green good. We consider two different scenarios. When consumers are...

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 compare a Bertrand with a Cournot duopoly in a setting where production is polluting and exploits natural resources, and firms bear convex production costs. We adopt Dastidar's (1995) approach, yielding a continuum of Bertrand-Nash equilibria ranging above marginal cost pricing also, to show...

This paper investigates the impact of free trade on welfare in a two-country world modelled as an international Hotelling duopoly with quadratic transport costs and asymmetric countries, where a negative environmental externality is associated with the consumption of the good produced in the...

Acquired wisdom has it that the allocation of pollution rights to firms hinders their willingness to undertake uncertain R&D projects for environmental-friendly technologies. We revisit this issue in a model where firms strategically choose whether to participate in an auction to attain...

We adopt a stepwise approach to the analysis of a dynamic oligopoly game in which production makes use of a natural resource and pollutes the environment, starting with simple models where firms' output is not a function of the natural resource to end up with a full-fledged model in which (i)...

We investigate the introduction of a minimum quality standard (MQS) in a vertically differentiated duopoly with an environmental externality. We establish that the MQS bites only if the hedonic component of consumer preferences is sufficiently strong. Then, we illustrate an underlying tradeoff...
