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...

This paper examines a characteristic of common property problems unmodeled in the published literature: Extracted common reserves are aften stored privately rather than immediately. We examine the positive and normative effects of such storage.

This paper generalizes Hotelling's (1931) theory of nonrenewable resources to situations where resource pools and their users are distributed spacially. Extraction and transport costs are assumed to be linear in the rate of extraction, but utilization of each deposit may require a setup cost.

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...
