Abstract

In this paper the long-run effects of demand and recharge uncertainty on the socially optimal management of groundwater reserves are studied. Demand uncertainty is modeled in a dynamic framework by letting the demand function shift randomly but continuously through time according to a random shock that follows a stochastic process. Likewise, uncertainty about natural recharge is characterized by identifying that variable as a stochastic process. The results show how the effects on long-run groundwater reserves depends crucially on the properties of the demand function. Basically, the long-run groundwater reserves increase (decrease) with an increase in uncertainty if the demand function is convex (concave). These effects occur because the random changes in demand and natural recharge cause an expected increase (decrease) in price depending on the curvature of the demand function. En este artículo se estudian los efectos a largo plazo de la incertidumbre de recarga y de demanda sobre la gestión socialmente óptima de las reservas de aguas subterráneas. La incertidumbre de demanda se trata en un marco dinámico dejando que la función de demanda cambie aleatoriamente pero continuamente a lo largo del tiempo de acuerdo con un shock aleatorio que sigue un proceso estocástico. Asimismo, la incertidumbre sobre la recarga natural se caracteriza identificando esa variable con un proceso estocático. Los resultados muestran como los efectos sobre las reservas de aguas subterráneas a largo plazo dependen crucialmente de las propiedades de la función de demanda. Básicamente las reservas de aguas subterráneasa largo plazo aumentan (disminuyen) con un aumento en la incertidumbre si la función de demanda es convexa (cóncava). Estos efectos ocurren porque los cambios aleatorios en la recarga natural y en la demanda provocan un aumento (disminución) esperado en el precio dependiendo de la curvatura de la función de demanda.
