Irrigation water demand for the decision maker

摘要: This paper deals with the problems of estimating irrigation water demand. We propose an original method estimation in two steps. First, we develop a dynamic programming model order to explain optimal management plan. Based on microeconomic approach describing farmer's behavior, this economic model, introducing agronomic and algorithm solution search, is used compute realistic database. Second, these data are estimate profit functions by non-parametric method. The demand function estimated using derivation procedure.An application proposed southwestern area France where conflicts appear frequently. same results for different climates: small quantities available, seems be quite inelastic. If one increases total quantity shape curve changes appears more elastic. threshold price at which price-responsiveness appears, depends weather conditions range from 0.30 F/m3 wet year 1.60 dry year. These crucial information regulator analyze effects regulation policy, based prices. impact increase will depend not only climate but also location initial final prices function.JEL classification: C14, C16, Q15
