We introduce a switching model to account for the interactions between management regimes (public vs. delegated) and Wss prices. This model also allows for spatial interactions between Wss and omitted spatial explanatory variables. The results confirm that forest land cover reduces the price of drinking water and that spatial factors influence the choice of management and prices. It was also found that the organization of the Wss influences water prices.

In France, all forest owners whose forests are located in a Natura 2000 site are eligible to enroll in a biodiversity conservation program by signing a Natura 2000 contract. In this case, the forest owner benefit from financial support that covers all additional costs for conservation and restoration measures and is also exempt from certain taxes such as land tax. Natura 2000 contracts were created as incentive-based conservation tools to enhance landholders’ participation to improve some identified ecological outcomes. Since landowners are very heterogeneous in terms of their preferences and values, it is crucial to understand the determinants of participation for those who signed the proposed contracts. Our study has several objectives: first, to ascertain whether the conservation program is attractive for the private forest owners who want to conserve the biodiversity of their land; second, to investigate which types of ...

The choice concerning the energy used for heating is modeled, stressing the combination between one type of energy used as a main source and another one used as a back-up. This endogenous decision has an impact on fuelwood consumption and is taken into account to avoid biased estimates of price and income elasticities. The results show that the choice of energy mix is determined by the income and the socio-economic characteristics of households, and that fuelwood consumption is price-sensitive in the case where wood is the main source of energy.

L’objectif de nos recherches est de montrer l’interet de ce concept pour analyser la deforestation cumulee sous deux aspects : en termes de deroulement du processus de deforestation via l’etude du moment ou il prend fin dans une economie qui se developpe ; en termes quantitatifs via l’etude de la surface totale de terres deboisees dans le pays au moment ou la deforestation cesse. En outre, l’analyse empirique de la transition forestiere permet de tirer d’importantes conclusions utiles aux decideurs publics, en particulier dans le domaine des politiques de lutte contre la deforestation. Le resultat de ces recherches montre que le developpement economique des pays et l’amelioration de la qualite des institutions jouent un role crucial dans la deforestation a long terme. Nos resultats suggerent egalement que, selon leur valeur, les...

Contrary to the agency, which is an expert in resource management, public authorities usually do not know the sustainable harvest level. In this paper, we model the contractual relationship between a principal, who owns the resource, and an agent, who holds private information on its sustainable harvest level, and look for the Pareto-optimal allocations. The agent can strategically use his private information to harvest outside the sustainability interval. We consider the case where the agent simultaneously interacts with several principals. From a simple dynamic spatial game, we show how the existence of multiple interacting principals with diverse qualities on information can help the least wellinformed principals to reduce the information rent and lead to the Pareto-optimal allocation.

Les recherches du LEF sur la periode 2005-2008 s'inscrivent dans un objectif general qui est de contribuer a developper un secteur integre de la ressource "foret" au produit "bois". En amont, cet objectif signifie la valorisation de toutes les fonctions de la foret en tenant compte des risques. En aval, il s'agit d'organiser la filiere et de promouvoir la valorisation du bois pour accroitre la competitivite du secteur. Le LEF est structure autour de deux axes : l'economie de la multifonctionnalite en foret ; les industries et marches du bois.

Agents of the community first choose to invest in their private project and in the CPR; second, they choose how much to extract from their private project and the commons. The model compares two types of risk management tool: CPR as risk-coping and risk-diversification mechanisms. It also compares two types of risk: risk on a private project and risk on CPR investment by other community members. The theoretical predictions are empirically tested with experimental economics. In this view, we propose an original CPR game composed of two periods, an investment one and an extraction one. Our result clearly shows that risk reduction in the private project unambiguously decreases investment in the CPR, while it does not impact CPR extraction. We also show that a risk-coping strategy is well understood as more flexible and influenced by the outcome in terms of private project yield.

From data on the procedures of delegation of water utilities, we estimate a price equation, taking into account the unobserved strategies of private operators and geographical effects. We show that the local strategy of the operator has a significant impact on the water price level and that neglecting it would lead to bias the effects of other factors.

L'analyse econometrique est realisee sur un ensemble de proprietaires aquitains ayant participe a une etude experimentale. Elle permet d'identifier separement les determinants de la participation a l'assurance et ceux expliquant les differences de consentements a payer (CAP). Cette etude s'interesse plus particulierement a l'impact de differentes formes de compensation publique : aide forfaitaire, aide forfaitaire contingente a l'assurance et subvention a l'assurance. Nous analysons aussi le role joue par l'esperance de perte, l'autoassurance, l'incertitude caracterisant la probabilite d'occurrence de l'alea (ambiguite sur le risque) et les caracteristiques reelles du proprietaire forestier et de sa propriete. Les resultats d'estimation montrent que le systeme d'aide publique forfaitaire francais a un impact negatif sur la decision d'assurance des proprietaires, tandis qu'une aide publique contingente a l'assurance est incitative. D'autres facteurs permettent d'expliquer la participation a l'assurance (ambiguite, caracteristiques individuelles...), et la demande d'assurance (esperance de perte, perception d'une aide publique dans le passe).
