Firms may voluntary abate pollution using one of two options: internalizing its own external effects and incuring abatement costs ("making") or delegating environmental protection by purchasing offsets ("buying"). We aim to elicit consumers' WTP for producers' use of the "making" option as...

Crop rotations are known to have two main kinds of economic effects: direct effects on potential yields and on the productivity of different inputs, and indirect effects on economically optimal input levels, especially pesticides and fertilizers. The main objective of this article is to uncover...

The concept of multifunctionality of fishing activities is emerging, as fishery activities do not only provide commodity goods but have others functions (environmental, social, territorial, etc.). We choose to focus on the provision of amenities, such as the presence of fishing boats or direct...

One way to reconcile the issues of productivity and environmental protection for field crops farmers is the implementation of systemic agroecological innovations. These innovations are complex combining traditional agricultural tools, such as the lengthening of rotations, with innovative...

[Paper in French] Open-access is probably the main cause of crowding on recreational sites, especially when they are attractive and close to urban areas. In this case, theory predicts equilibrium and optimum differ due to externality of congestion. Whereas Fisher and Krutilla, 1972, caracterized...

A usual explanation to low levels of contribution to public goods is the fear of getting the sucker’s payoff (cooperation by the participant and defection by the other players). In order to disentangle the effect of this fear from other motives, we design a public good game where people have...

The well-known increase in the geographical concentration of hog production suggests the presence of agglomeration economies related to spatial spillovers and inter-dependencies among industries. In this paper, we examine whether the restrictions on land application of manure may weaken...

The 2008 food crisis has challenged the political legitimacy and economic efficiency of the liberalization of international agricultural trade. An alternative vision defended by the food sovereignty movement is that long-term food security cannot rely on dependency on food imports, but must be...

This article provides an analysis of the European Commission’s proposals (18 Novembre 2010) regarding the next CAP reform. It proposes a reflection centered on the volatility of agricultural prices, the market regulation mechanisms and the risk management tools (the important question of...
