The expansion of a given land use may affect deforestation directly if forests are cleared to free land for this use, or indirectly, via the displacement of other landuse activities from non-forest areas towards the forest frontier. Unlike direct land conversion, indirect land-use changes affecting deforestation are not immediately observable. They require the linking of changes occurring in different regions. This paper empirically estimates these indirect effects for the case of Brazil. It presents evidence of a positive relationship between sugarcane expansion in the south of the country and cattle ranching in the Amazon, suggesting that the former is indeed displacing the latter towards the forest frontier. This displacement effect is shown to be a dynamic process materializing over 10 to 15 years.

Demand for oil is very price inelastic. Facing such demand, an extractive cartel induces the highest price that does not destroy its demand, unlike the conventional Hotelling analysis: the cartel tolerates ordinary substitutes to its oil but deters high-potential ones. Limit-pricing equilibria of non-renewable-resource markets sharply differ from usual Hotelling outcomes. Terms of use: Documents in EconStor mayResource taxes have no effect on current extraction; extraction may only be reduced by supporting its ordinary substitutes. The carbon tax applies to oil and also penalizes its ordinary (carbon) substitutes, inducing the cartel to increase current oil production. The carbon tax further affects ultimately-abandoned oil reserves ambiguously.JEL-Code: Q300, L120, H210, Q420.

This paper investigates the direct and indirect impacts of ethanol production on land use, deforestation and food production. A partial equilibrium model of a national economy with two sectors and two regions, one of which includes a residual forest, is developed. It analyses how an exogenous increase in the ethanol price affcts input allocation (land and labor) between sectors (energy crop and food). Three potential effects are identified. First, the standard and well-documented effect of direct land competition between rival uses increases deforestation and decreases food production. Second, an indirect displacement of food production across regions, provoked by a shift in the price of food, increases deforestation and reduces the total output of the food sector. Finally, labor mobility between sectors and regions tends to decrease food production but also deforestation. The overall impact of ethanol production on forest conversion is ambiguous, providing a number of interesting pointers to further, empirical research.

We present a synthetic model of a non-renewable-resource sector where deposits must be costly developed before they are exploited; the analysis emphasizes the effect of resource taxation on the discouragement to the development of new reserves. We discuss the limitations of neutral profittaxation schemes and examine the distortions caused by various resource-taxation systems on the rent and its allocation: tax evasion, royalty-induced distortions, imperfect tax commitment, agency issues... We also discuss the measurement of resource rents for taxation purposes, and issues with the management of the resource tax income. JEL Classification codes: Q30; H20. Taxer la rente d'exploitation des ressources non renouvelables : une note théoriqueCette étude analyse la rente générée par l'exploitation d'une ressource non renouvelable, ainsi que la taxation de cette rente. Dans un modèle simple, nous représentons une industrie minière dont les gisements de ressource non renouvelable, pour être exploités, requièrent des efforts de développement ; l'analyse porte principalement sur les effets néfastes de la taxation sur la production de nouvelles ressources. Nous évoquons les limites à la possibilité théorique de ponctionner les profits de manière neutre, puis examinons les distorsions impliquées par les systèmes de taxation existants : évasion fiscale, capacité d'engagement limitée, rede...
