Both product differentiation through quality and capacity commitment have been shown to relax price competition. However, they have not been considered simultaneously. To this end we consider a three stage game where firms choose quality then commit to capacity and finally compete in price.

In the framework of symmetric Cournot oligopoly, this paper provides two minimal sets of assumptions on the demand and cost functions that imply respectively that, as the number of firms increases, the minimal and maximal equilibria lead to (i) decreasing industry price and increasing or...

When the production of high quality needs the employment of qualified labour, firms' decisions concerning quality are affected by the extent to which skills are abundant. By means of a comparison between monopoly and perfect competition, we show how market power in such a context may entail a...

We study the introduction of new products in a vertically differentiated industry. Innovative firms have to engage into reducing time-to-market investments in order to shorten the time interval between innovation and sales. Still, these investments generate irreversible costs which have to be...

In this paper, the authors consider a European industry characterized by vertical product differentiation. Using a two-stages model with quality choice made before price competition takes place, the authors show that EU antidumping policy that takes the form of price-undertaking offers a...

In a model of horizontal product differentiation, we show that local monopolied may exist under free entry when capital is perfectly mobile. In contrast both with the situation of restricted entry and with the zero-profit approach to free entry outcomens of Salop 91979), the unit profit rate of...

The persistent uncertainty about mid-century CO2 emissions targets is likely to affect not only the technological choices that energy-producing firms will make in the future but also their current invest- ment decisions. We illustrate this effect on CO2 price and global energy transition within...

This paper examines the impact that uncertainty over economic growth may have on global energy transition and CO2 prices. We use a general-equilibrium model derived from MERGE, and define several stochastic scenarios for economic growth. Each scenario is characterized by the likelihood of a...

We analyze the incentives of internet service providers (ISPs) to break net neutrality by excluding internet applications competing with their own products, a typical example being the exclusion of VoIP applications by telecom companies offering internet and voice services. Exclusion is not a...

We propose a general model of monopolistic competition, which encompasses existing models while being flexible enough to take into account new demand and competition features. The basic tool we use to study the market outcome is the elasticity of substitution at a symmetric consumption pattern,...
