Résumé
(trad auto)The thesis aims to compare the effectiveness of economic instruments (fixed or flexible taxes) for the management of coastal aquifers in a context of information asymmetry. It is divided into four chapters. The first chapter is an essentially introductory and methodological chapter that presents the field of study that motivated the thesis and justifies the use of experimental economics to judge the effectiveness of the proposed management instruments. Chapter two proposes a theoretical model for regulating groundwater withdrawals. The objective is to take into account the characteristics of the Roussillon plain in order to develop laboratory tests. Chapter three proposes an experimental study of the effectiveness of selected economic instruments in groundwater regulation. The first part of this chapter specifies the expected theoretical results concerning the samples taken following the use of a particular instrument. The next two parts present the experimental design and the results respectively. Chapter four discusses the external validity of the experimental method using econometric methods to extend the use of experimental data to more general contexts.
