This paper evaluates alternative strategic models of competition and market structure in online retailing, and makes comparisons with traditional retailing. Online consumers are less concerned than traditional consumers about spatial characteristics and more concerned about hidden quality...

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...

This study examines the response of oil contracts to extreme price movements. The chosen contract form is a Production-Sharing Agreement (PSA) which is the oil industry`s equivalent of sharecropping and one of the most commonly used contractual agreements. We show that only the two significant...

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...
