[paper in French] This article aims at identifying and analyzing coordination and contracting schemes in food supply chains. We provide a literature review related to the contracts between farmers and processing firms. We examine how the development of contracts can be used as an alternative to...

We consider different models that assess eco-efficiency in the perspective of production frontier estimation. These models span from the ones that consider bad outputs as inputs, or as outputs under the weak disposability assumption, or under the weak G-disposability and the materials balance...

[paper in French] The growing concern of the selection of bacteria resistant to antimicrobials and their possible transmissions to humans lead French Authorities to implement several legislative measures to decrease antimicrobial use in livestock production. This context leads to question...

[paper in French] Compensation measures require a developer to offset the negative effects of the project. Two types of approaches are possible. The first one is based on the compensation claim: in this case the developer looks for surfaces on which he can offset its grip. The second focuses on...

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...

The financial development of agricultural markets is not recent. But, starting early 2000, a large amount of investments on commodity markets, including agriculture, have been realized using innovative instruments. And in 2007-08, the continuous increase of investment was simultaneous with...

We investigate the role played by both production and market risks on farmers’ decision to adopt long rotations considered as innovative cropping systems. We build a multi-period dynamic farm model which arbitrates each year between conventional and innovative rotations. With discrete...

Qualitative change is widely recognized as a defining feature of evolution. Schumpeter and Georgescu-Roegen put it at the center of their methodological reasoning. I revisit important contributions of these two authors, paying attention to the immediate relationship of the major traits and...

The travel cost method is widely used to estimate the value of recreational sites and to simulate the impact of public policies on welfare. Congestion is likely to be a determinant of recreational demand (Jakus and Shaw, 1997) and has to be given special attention. Ignoring this variable leads...
