This paper studies how the existence of a potential entrant influences an incumbent’s choice of quality in a model of vertical product differentiation and entry. Both firms face fixed set-up costs and quality-dependent costs of production, and compete on quality and price. With identical...

Following new legislation the Swedish electricity market is about to be deregulated. The new system is designed to ensure competition in production and supply. The Swedish electricity market is characterised by a high degree of concentration on the seller side. In this paper we use a simple...

The purpose of this paper is to quantitatively evaluate the impact on electricity prices of deregulation and free trade in the Nordic countries. The analysis is focused on the impact of increased competition on market power and the degree of monopolistic pricing. The major tool for our analysis...

Equilibrium prices of the variants of a differentiated commodity are shown to increase if the variants become closer substitutes, under a set of circumstances, which is by no means pathological. Rather, the underlying argument has a bearing on market prices, whenever a potential buyer does not...

In a model of vertical product differentiation, duopolistic firms face quality-dependent costs and compete on quality and price in two segmented markets. Minimum quality standards, set uniformly or according to the principle of mutual recognition, can be used to increase welfare. The analysis...

We develop a model of search among substitutes for the best combination of commodity variant and price, in which the structure of search costs can be manipulated by the suppliers of these variants, e.g. by joining an existing market or opening a new one. We analyse the subgame perfect equilibria...

In a model of vertical product differentiation, duopolistic firms face quality-dependent costs and compete on quality and price in two segmented markets. Minimum quality standards, set according to the principle of Mutual Recognition, can be used to increase welfare. The results of the one-shot...

This paper investigates why subjects in laboratory experiments on quantity precommitment games consistently choose capacities above the Cournot level - the subgame-perfect equilibrium. We argue that this puzzling regularity may be attributed to players' perceptions of their opponents' skill or...

The paper demonstrates that, even when firms' initial moves are simultaneous, the mere opportunity to wait out the opponent's move may be as harmful as a secondmover disadvantage.
