[fre] Bien que la France ait écarté jusqu’ici l’idée de recourir à des instruments incitatifs pour réduire la pollution diffuse aux nitrates, cet article revient sur le potentiel de ces instruments tels qu’ils ont été employés par certains de nos voisins européens ou, à défaut,...

In nonpoint source pollution problems, the regulator does not observe each polluter’s individual emission, which prevents him from using the conventional policy instruments. Therefore, new instruments have been designed to regulate this type of pollution. In an experiment, we compare the...

When information on farmers’ farming methods is incomplete, it isnot optimal to fight water pollution due to their activities exclusively through a tax policy. Symmetrically, subsidies alone are not appropriate for some cereals which are already widely subsidized in the European Union. In this...

Recent surveys report the increasing number of muddy flows in many areas, and point out the fact that agricultural practices (among others) influence significantly the risk and severity of muddy flows. In this paper, we investigate the economic incentives that can be given to the farmer to adopt...

We provide a new experimental investigation of the neutrality theorem of Warr (1983), according to which “when a single public good is provided at positive levels by private individuals, its provision is unaffected by a redistribution of income". Our experimental design differs from Chan...

In a laboratory experiment, we investigate behavior in a principal–agent situation with moral hazard. We evaluate the predictive success of two theories. One is the standard agency theory, which assumes that the agent will accept any contract offer that satisfies his participation...
