La Participation des Adhérents Dans Leurs Coopératives Agricoles: Une Étude Exploratoire du Secteur Céréalier Français

When a farmer joins an agricultural cooperative, he or she undertakes to participate in the cooperative economically, as a co‐operator, and also in its administration, as an associate. Yet, today, researchers and directors of cooperatives are observing a drop in member participation in both spheres. The goal of this paper is to build a typology of the members of grain farmer agricultural co‐operatives in France, based on the members’ participation, and then use a multinomial probit model to identify the factors that come into play and result in a member belonging to a given category in the typology. We make the hypothesis that attitudes with respect to organizational involvement and the member's confidence in his or her co‐operative can explain these differences in behavior, along with individual variables tied to the member and his or her farm business, and variables associated with the co‐operative to which the member belongs. Following the analysis of the participation behavior of the 290 members in the sample, the members can be grouped into three distinct categories: “individualists,” “good soldiers,” and “engaged.” The results of the multinomial probit model on these three categories show, in particular, that attitude toward organizational involvement has a significant effect, as do the presence of storage on the farm and the size of the cooperative on the probability of being an “individualist” rather than a “good soldier” or “engaged.”     

L’Évaluation économique de l'investissement dans la conservation des sols: Le cas des aménagements antiérosifs dans le bassin versant du lac Lagdo au Cameroun

This article presents an analysis of the economic impact of erosion control facilities on farm operations in the watershed of Lake Lagdo in Cameroon. Over the past several decades, erosion control facilities, which are erosion control techniques, have been introduced in Cameroon. No assessment of the impacts of these on farm operations had yet been made. Drawing on data from a survey carried out in 2007 and 2008 and a switching regression model, the study concentrates on the effectiveness of the production factors of parcels of land with and without erosion control facilities. The comparison of the average crop yields of the operations in our sample that either adopted or did not adopt such facilities shows a significant difference, representing up to 10% of the value of the farm production. Proof of a positive selection bias is also found, indicating that the farms with above‐average crop yields are more likely to adopt erosion control facilities. Such facilities on the parcels of land also provide an advantage in terms of increasing the productivity of inputs. The analytical approach developed and the positive conclusion of the selection bias can be pertinent to assessing other soil conservation technologies promoted in the area.     

Quel prix pour la sécurite alimentaire? Une évaluation contingente suite à la crise européenne de la ≪ vache folle ≫

L'hypothèse d'une éventuelle contamination humaine par la maladie de Creutzfeldt‐Jakob, par le biais du prion de I'encéphalite spongiforme bovine (ESB), faite en 1996 par le ministre de la santé anglais a étéè l'origine d'une perte de confiance des consommateurs dans la viande de b?uf. Lew comportement en France a étéétudié a partir d'une enquête menée en 1997, auprés d'un échantillon représentatif de 700 personnes résidant dans l'agglomération de Rennes en Bretagne. L'enquête présente aux personnes interrogées un scénario contingent visant èévaluer leur consentement è payer (CAP) afin de disposer d'une viande pour laquelle tout risque de contamination par l'ESB est écarté. Un processus original de révélation des CAP a été utilisé, combinant la méthode du référendum et un système d'enchères. Le CAP moyen obtenu est relativement élevé puisqu'il atteint 22 % du prix initial de la viande. Un modéle micro‐économique visant è expliquer la valeur du CAP du consommateur pour une sécurité alimentaire totale par rapport è l'ESB est alors présenté. De cette formalisation micro‐economique découle une spécification économétrique correspondant au modele multinomial logit ordonnéè seuils connus. Parmi les variables ayant un role determinant dans le choix du CAP des consommateurs figurent notamment la confiance dans les indications géographiques et les labels. After the British Minister of Health admitted a possible link between the BSE prion and the Creutzfeldt‐Jakob disease in 1996, consumers lost confidence in the beef sector. This paper analyses consumers behavior after the BSE crisis in France in 1997, based on a survey using a random sample of 700 people located in the area of Rennes (Bretagne). Particularly, a contingent scenario was proposed to the respondents to elicit their willingness to pay (WTP) to have beef which would not transmit CJD using a mix of the referendum method and the bidding process. The mean WTP reaches 22% and is consistent with results obtained in other studies. A microeconomic model is proposed and an econometric approach based on an ordered logit model is developed. Among the significant variables, it is interesting to note the role of stamps of quality to explains consumers'behavior. Such variables prove the interest of a transparency and tracability policy to restore the consumers confidence.     

Institutional Market Power in Comté: Insights from a ‘Double Marginalisation’ Model

This article explores the economic efficiency of a horizontally and vertically coordinated industry where upstream producers are atomised, but downstream processors are few, explicitly considering participation incentives and allowing the coordinated industry to exert market power towards buyers. The model offers insight into the probable social impacts of the government‐sanctioned supply control scheme in place in the French Comté cheese market, suggesting it falls short of constituting a Pareto‐improvement compared with a laissez‐faire situation. More generally, our theoretical model provides guidance to identify instances where encouraging industry coordination may be socially desirable. We formally introduce the concept of ‘seller‐equivalent degree of overall market power’ of the separated industry, a market characteristic comprised of measurable or inferable parameters, the value of which is shown to determine the potential for Pareto improvements through industry integration.     

Efficacitè technique et coûts de production dans les secteurs laitiers du Québec et de l'Ontario

This study aims to estimate the level of technical efficiency in milk production and to analyze the relationship between the costs of production, the level of technical efficiency and farm size. Furthermore, the socio-economic variables that characterize the most efficient farms and those producing at lower cost are identified. The results indicate that in Quebec, the level of technical efficiency increases with herd size, but this increase is very small. In Ontario, herd size is not significant to explain technical efficiency. The level of education, the participation in milk recording programs, expenditures per cow fort are and artificial insemination, the quality of hay and the number of years as member of a management club are a11 variables that characterize efficient farms.
