We model the interactions between management regimes (municipal vs. delegated) and operating costs of water supply services in order to compare their performance and pricing. We estimate the models from panel data in France. We show that the choice between management regimes at the local...

We analyze duopolistic competition between horizontally differentiated firms selling durable goods or services subject to congestion. At each point of time, new customers buy one unit of the commodity from one of the firms, by comparing present prices and future congestion rates. We study the...

We propose methods for testing hypothesis of non-causality at various horizons, as defined in Dufour and Renault (1998, Econometrica). We study in detail the case of VAR models and we propose linear methods based on running vector autoregressions at different horizons. While the hypotheses...

We model capacity-building investments in a homogeneous product duopoly facing uncertain demand growth. Capacity building is achieved through the addition of production units that are durable and lumpy and whose cost is irreversible. While building their capacity over time, firms compete à la...

The purpose of this paper is to offer a glimpse into the potential industrial organization of the property casualty insurance (P&C) market if banks continue to penetrate it at current rates. To do so, we study an insurance market where banks are already integral in distribution: Title insurance....

We analyse the effects of a price floor on price wars in the retail market for gasoline. Our theoretical model assumes a Bertrand oligopoly supergame in which firms initially collude by charging the monopolistic price. Once firms detect a deviation from this strategy, they switch to a lower...

We study the interactions between the capital structure and the technological flexibility choices of firms in a duopoly. When there are bankruptcy costs, a leveraged firm may modify its strategic choices in order to decrease its probability of bankruptcy. We show that, when the capacity level of...

A model of location choice by Cournot oligopolists is presented, under the assumption that R&D spillovers depend on the distance between firms. We show that a variety of patterns emerge. Agglomeration is optimal under certain assumptions. Geographical dispersion in a two-dimensional plane is...
