An increase in the demand for agricultural goods leads to the use of more intensive cultivation methods. Though Ricardo sees no difficulties in the intensification process, their existence is revealed by the possible occurrence of multiple equilibria. A general theory of intensive rent is based...

This article proposes a theory of banking of emission permits under conditions of regulatory uncertainty. Based on a two-period partial equilibrium framework, we examine the effects of increasing risk - in the sense of a mean-preserving spread - regarding a future permits allocation at the...

This article investigates firms’ banking and pooling behaviors in the context of the EU Emissions Trading Scheme (EU ETS) during Phase I (2005-2007). It provides an overview of the questions raised at the firm-level by the introduction and implementation of the EU trading system in terms of...

Nous proposons d'étudier dans un modèle à deux secteurs de production, les effets d'une incertitude portant sur la qualité de l'environnement sur les comportements de choix de portefeuille et d'épargne des agents. Nous supposons que les individus investissent dans les firmes par...

The well known economic advantage of tradable permits over command and control obviously vanish if firms do not trade because of policy uncertainty. In fact, uncertainty about changes in the permits program could make firms reluctant to invest in tradable permits. This article proposes to give...

This article study the impact of risk perception on environmental policy. The environmental quality is uncertain and can be improved by voluntary contributions. We introduce then an heterogeneity in individuals' risk perceptions. In this context, the social optimum can be decentralized by tax...

This paper investigates the economic consequences of permits allocation rules. Following the rapid development of the Kyoto Protocol and the EU Emission Trading Scheme, it appears critical to better understand the procedure of allocation of permits between countries/firms and its distributive...

In this article, we consider illiquid life annuity contracts and show that they may be preferred to Yaari (1965)’s liquid contracts. In an overlapping-generation economy, liquid life annuities are demanded only if the equilibrium is dynamically inefficient. Alternatively, an equilibrium...

In this article, we study the optimal level of prevention in the face of an uncertainty on the health status. We analyze the individual choices of primary prevention and secondary prevention when the probability of appearance of the disease is not perfectly known. In order to distinguish the...
