Collective Voluntary Approaches to Food Safety with Heterogeneous Firms: Monitoring and Design? AgEcon
Bignebat, Celine; Rouviere, Elodie.
Collective quality management systems are well known instruments to manage the quality and/or the safety of foodstuffs. They can be considered as voluntary approaches to food safety. In environmental economics some empirical studies emphasize that firms entering into a collective voluntary program behave differently because their motivations differ. To the best of our knowledge, there is no formal discussion on the effectiveness of a collective voluntary program in which firms adopt different behaviour once they entered the program. Starting from this two strand of literature, we extend the analytical framework of collective voluntary approaches considering heterogeneous firms and applying it to food safety issues. We show that according to firm’s...

Demand for seasonal wage labour in agriculture: what does family farming hide? AgEcon
Darpeix, Aurelie; Bignebat, Celine; Perrier-Cornet, Philippe.
Seasonal wage labour was rarely distinguished from the permanent one in farm-household models although it has sharply increased in developed countries. Therefore, we propose to endogenize the demand for this peculiar labour type and highlight the trade-offs for the various labour combinations on farms. We use data on fruit and vegetables farms drawn from the 2000 French agricultural census. We show that seasonal wage labour is a substitute for permanent wage employment, and doesn't entirely follow the seasonality of the agricultural activity: competition on the labour and product markets play a significant role in the employment of labour types.

Joint evolution of spatial integration and product segmentation on agricultural markets: the case of cereals in Mali AgEcon
Aubert, Magali; Bignebat, Celine; Egg, Johny.
Within the context of liberalisation experienced by the Malian economy since the beginning of the 1990s, spatial integration of cereal markets has been considered as a major tool as to avoid localised shortages due to production shortfalls. However, market dynamic reveals since then new patterns: the diversification of urban consumer demand towards "modern cereals", in particular rice and maize, drives the segmentation of the cereal market. As consumer s are likely to substitute traditional cereals, like millet and sorghum, for other cereal types, new market segments emerge. We account for this evolution with a theoretical model à la Hotelling : the good is considered according to two characteristics, the spatial localisation (local market) and the cereal...

Linking small producers to supermarkets? The role of intermediaries on the fresh fruit and vegetable market in Turkey. AgEcon
Bignebat, Celine; Koc, A. Ali; Lemeilleur, Sylvaine.
A wide range of the empirical studies shows to what extend the rise of supermarkets in developing countries deeply transform domestic marketing channels. In particular, the exclusion of small producers from the so-called dynamic marketing channels (that is remunerative ones) is at stake. Based on original data collected in Turkey in 2007 at the producer and the wholesale market levels, we show that the intermediaries are decisive in order to understand the impact of downstream restructuring (supermarkets) on upstream decisions (producers). The results show first that producers are not aware of the final buyer of their produce, as intermediaries hinder the visibility of the marketing channel, their choice is restricted to that of the first intermediary....

Local diversification of income sources versus migration: Complements or Substitutes? Evidence from rural families of the Senegalese Groundnut Basin AgEcon
Sakho-Jimbira, Maam Suwadu; Bignebat, Celine.
Much has been written to show the importance of diversification for rural African households because of the considerable share of non-farm revenues in total income (Reardon, 1997; Reardon et al., 1998). The literature points out push and pull factors explaining that risk and adverse shocks which characterize farm activities urge rural population to diversify into more profitable non-farm activities. But less attention has been paid to the distinction between two diversification patterns, namely local diversification and migration, and their relationship. Drawing on the theoretical and empirical literature, we identify the advantages and drawbacks of local diversification versus migration decision in terms of expected pay-offs for the family and the...

Marketing Cooperative vs Producer's Agent: The Turkish Dilemma in Modern FFV Market AgEcon
Lemeilleur, Sylvaine; Bignebat, Celine; Cordon, J.M..
Since the rapid expansion of modern retailers in Turkish agro-food market, competent intermediary's forms are required to match up their exigent demand in fresh fruit and vegetables (thereafter FFV) procurement - namely, volume, regularity or quality- with a very fragmented national supply provided by small family farms. In this context, the aim of this paper is twofold: it first develops a unified theoretical framework that compares the costs incurred by producers when deciding to market their produce through a private agent or through a marketing cooperative. Drawing on marketing cooperatives theories and transaction cost arguments, we put forward that these systems do not prove the same ability to allow for quality upgrading, above all at the producer's...
