We consider a model with two energy sources, a non-renewable one, cheap but polluting, and a renewable one, expensive but clean, let’s say coal and solar. The aim of environmental policy is to maintain atmospheric carbon concentration under a given ceiling, chosen to prevent an excessive rise...

In this paper we consider the problem of compatibility between networks when the consumers of a network service value the capacity of the network itself rather than the number of users. Compatibility decisions are modelled as the outcome of a three stages game where strategies include...

The present issue of Annals of Economics and Statistics attests the vitality of the research in environmental and natural resource economics in France, after the special issues of Revue d’Économie Politique in 2008 and Économie et Prévision in 2009, to cite the more recent evidence only....

We consider a Stackelberg like duopoly in which the strategy space of the firms are price-quantity pairs, meaning that, at this price, a firm is willing to sell at most the supplied quantity. It is shown that, at the equilibrium, the leader will quote a price lower than the price quoted by the...

Sand and gravel mining is one of the main extractive industries in France. Extraction implies generally a loss of some agricultural potential, i.e. the destruction of some agricultural asset. Such a problem has recently arisen in the Bordeaux area, well known for its wine. In this paper, we show...

Fossil fuel use causes the atmospheric accumulation of carbon. The society, endowed with an alternative clean renewable energy, aims at keeping this pollution stock below a prescribed target. The use of an abundant and costly backstop shall follow the exhaustion of the polluting resource; in case...

Now widespread in many french wine market places, the so-called "en primeur" sales policy, that is selling part of the production before wine is bottled, appears to be a form of intertemporal price discrimination. Surprisingly enough, wine is actually sold at a lower price "en primeur" than...

It is generally expected that profit maximisation leads a firm to choose a more flexible plant the more uncertain its demand function is and/or the more variable is the sequence of quantities to produce. In this paper we make explicit the precise conditions under which this intuitive argument is...

This paper is an attempt to give a precise content to the notion of potential competition in a natural monopoly market. Competition is described as a two stage game in which a set of firms announce first a price, then a level of output. Contingent demands for each firm are obtained from a...

A partial equilibrium analysis shows that a pool of natural resources with constant unit costs of extraction has to be exploited in strict increasing cost order. Kemp and Long [1980] have shown that it is not necessarily the case in a general equilibrium framework. In a consumption-leisure...
