La gestion du sanglier : modèle bioéconomique, dégâts agricoles et prix des chasses en forêt domaniale

[paper in French] Wild-boar can be considered both as a resource and as a pest. It causes collective damages and is also valued resource for recreative activity as hunting. The paper treats the economy of controlling a hunting game. A bio-economic model is presented and used for the analysis. The optimal population of big game is the one minimizing the present value of the hunter willingness to pay less agricultural damages with an infinite time horizon. We take into consideration the loss of the hunter welfare from a decrease in game population. For the empirical analysis, we used data on agricultural damages caused by wild-boar in order to reconstruct their population dynamics. Hunter marginal implicit prices for game hunting were estimated using the hedonic price method on a sample of hunting lease prices in eastern French forests. The long term equilibrium solutions can provide elements for optimal control strategies of wild-boar
