We examine the effect of the introduction of uniform water-charging for aquifer management and provide evidence using a survey-based choice experiment of agricultural water users in rural Tunisia. Theoretically, we show that the implementation of the proposed second-best regulation would result...

We show how the need to model new empirical phenomena has induced the literature to rethink model specifications and to address new questions...

La multifuncionalidad agraria es el reconocimiento del ejercicio conjunto por parte de este sector de funciones económicas, ambientales y sociales. Sin embargo, no todas estas aportaciones al conjunto de sociedad son valoradas en los mercados, sino que buena parte de ellas son bienes públicos....
