A model of duopoly competition in nonlinear pricing when firms are imperfectly informed about consumer locations is analyzed. A continuum of consumers purchase a variable amount of a product from one of two firms located at the endpoints of the market.

This paper presents an amenity-based theory of location by income. The theory shows that the relative location of different income groups depends on the spatial pattern of amenities in a city.

Few oligopoly models address the problem of tacit collusion when there is the possibility of entry. One model that does so is the well-known Loschian model of spatial competition. The purpose of this paper is to present a reexamination of this model within the context of game theory. The authors...

Since many important firms operate several plants, the problem of the choice of an optimal pattern of locations for these plants is of interest. In this paper, multiplant location without interaction is studied. It is shown that it is sufficient to consider a finite number of particular sites to...

The critical role of free entry to correct inherent deviance behavior has been stressed by Vanek (1970), Meade (1972) amongst others. The equivalence theorem (Dreze 1976) defines that labour and entrepreneurial management both lead to the same Pareto optimal equilibrium provided that there is...

This paper studies a strategic market game where agents fragment their bids on different markets. Simple conditions for existence of an interior equilibrium point are provided. In equilibrium, all agents are active on the same markets and prices are identical across markets, so that all...

The paper proposes an original class of conditionally heteroskedastic models aimed to capture a new concept of asymmetry. Not only past up and down moves of stock market returns have different impacts on the conditional variance, but also, positive and negative changes are governed by different...
