ABSTRACT We develop a bilateral oligopoly framework with manufacturer‐retailer bargaining to analyze the impact of retail mergers on market outcomes. show that surplus division between manufacturers and retailers depends three forces can be interpreted in terms an “equilibrium fear”. estimate our French soft drink industry find have greater power than manufacturers. Using counterfactual simulations, we highlight increase retailers' fear disagreement relative manufacturers, which weakens...

The paper determines how the value‐added created by an organic label is shared in a vertical chain among manufacturers and retailers. Using purchase data on French fluid milk sector, we develop structural econometric model of demand supply that takes into account bargaining power between Our results suggest segment more profitable, as it permits existence higher margins. Moreover, allows to achieve relative retailers, hence obtain share total then used assess impact environmental policy...

Abstract This paper investigates empirically the determinants of agro‐food firms’ adoption Protected Designation Origin (PDO) label. A unique dataset containing firm‐level cost and production information on French Brie cheese is used, covering period 1980–2000. The data are especially relevant as PDO producers have coexisted with other non‐PDO since 1981. To evaluate producers’ incentive to opt for certification, we use a structural switching regression model which incorporates structure...

European Union regulation on quality food products (protected designations of origin (PDO) labelling) is expected to sustain competitiveness within the agricultural sector. This paper examines impact this policy survival cheese firms over period 1990–2006 in France. We show that such a (Appellation d'Origine Controlée) reduces exiting risk for smaller firms. However, still have lower rate compared with larger ones cannot be compensated by label effect.

This paper explores the impacts of Protected Designation Origin (PDO) certification on costs and profits firms as well consumers’ total welfare. The argues that PDO labels are different from other common labeling schemes, they involve technological capacity constraints influence their economic efficiency. Using a theoretical model endogenous quality choice, which incorporates vertical differentiation with linked to label, we explore way producers can signal either by certifying product...

There is a renewed interest in collective action agriculture, both at the policy and research level. Groups of agricultural producers, small large, form to make joint investments processing marketing facilities, share reputation, bargain with supplying, retailing firms, gain access distant and/or foreign markets, spread costs extension services, name few examples. These groups are common many countries, even though they known different names, such as cooperatives, producer organisations...

Collective labels are widespread in food markets, and either separated or nested with private brands—the latter known as “nested names”. We propose a model to explain the rationale of names, collective being effective reaching unaware consumers, while individual brands help firms reach aware consumers. also incorporate decision‐making within group producers joining labels, taking into account their heterogeneity providing quality. show that names emerge when consumers become more information...

Abstract This article provides a new explanation for the positive role of cooperatives in quality provision along agri‐food chain. We study economic rationale cooperative acting as an intermediary between producers and downstream (DS) firm when DS cannot observe individual but only average quality. derive optimal contract to elicit quantity incentives producers, depending on whether directly deals with or indirectly them through producer‐owned cooperative. find that via secret contracts,...
