The economic effects of environmental taxes depend on the market structure. Under imperfect competition with free entry and exit, environmental taxes have an impact on economies of scale by changing the number and size of firms. Whether economies of scale rise or fall in a particular industry...

In this paper we consider a two good general equilibrium model with one good being produced from the other and being sold in an oligopolistic market. We assume that the representative consumer has a Cobb-Douglas utility function and the firms face constant unit cost of production. We show that...

In general equilibrium models with oligopolistic firms, equilibrium outcomes may depend on the choice of numeraire. When firms have the power to influence prices strategically, different price normalisations entail objective profit functions which are generally not monotone transformations of...

We analyze whether different learning abilities of firms with respect to general equilibrium effects lead to different levels of unemployment. We consider a general equilibrium model where firms in one sector compete a la Cournot and a real wage rigidity leads to unemployment. If firms consider...

Industrial prices of goods and services are a function of costs of production and of the mark-up that firms apply on those costs. If these prices relate to goods that are traded internationally, they will also be influenced by the price at which those goods are exchanged in international...

This paper explores the impact of product liability on vertical product differentiation when product safety is perfectly observable. In a two-stage competition, duopolistic firms are subject to strict liability and segment the market such that a low-safety product is marketed at a low price to...
