The declining price anomaly for sequential sales of identical commodities challenges auction theory which predicts constant prices within a day. Among hypotheses explaining the phenomenon stands the dual value of goods including a risk premium in early transactions. We consider that asymmetric bidder groups and shortage periods may also affect...
The aim of this paper is to specify the arising preferences within a theory of demand for seafood products through a socio-economic quantitative analysis. The relevance of standard economic variables is discussed by introducing additional socio-demographical variables in a multivariate statistical analysis. The position of seafood among other food products...
A recent study in agricultural products has brought out evidence of asymmetrical transmission of price changes according to the sign (positive or negative) of past variation. Interestingly, asymmetry was more commonplace for products with a lower elasticity of supply due to the perishable nature of products. A similar study based...
It has been recently reported that the major canned fish found in international trade –tuna- was first canned in 1903 in southern California. This US-centric view regrettably omits the important foreign trade of canned fish products borne as far back as the late 1820s in Europe, birth place of this...
Game and experimental theorists have specified the conditions under which different auction systems may lead to distinct price levels. By changing the sales organisation, the introduction of electronic auction systems on first-hand fish markets is expected to have modified bidders' habits, hence affecting the price levels. A demand model based...
When dealing with time, a fishery manager faces a major difficulty. On an N-period time horizon, should he follow
several short-run objectives for every n sub-period, or should he consider only the long-run objective? If a European
manager trying to implement a stock recovery plan prefers to achieve the long-run...
Methodological difficulties, particularly when multifleet-multispecies fisheries are active, explain pro parte a weak research effort on the socio-economic impact of fishery activities after the implementation of a marine protected area. Two components of the socio-economic impact have been prioritized: the fishing unit profitability and the fishery household income distribution by...
Over the past century, the tuna canning industry has been dominated by a few big companies, some of
them having changed of ownership or merged: these oligopolistic firms are the “big three” in the USA,
Van Camp, Star Kist, and Bumble Bee, the French Saupiquet, the Italian Trinity Alimentari and...
Fresh fish trade in Kribi, Cameroon is characterized by high uncertainty in a context of specific assets. Facing this uncertainty, actors have developed hybrid coordination mechanisms centered on contractual arrangements and networks. These implicit contractual arrangements involve price negotiation, delivery agreements between fishermen and buyers, as well as transactions including...
Some recent studies have shown the outstanding price linkages at the global scale between the cannery-grade
tuna markets over the last decade. When it comes to price transmission along the European value chains, opposite results between the two major species (skipjack and yellowfin) are found: the market for final goods...
As compared to other countries, France has been involved very lately in the discussion about fisheries ecolabelling. Reluctant to adopt the existing ecolabels, the professional organisations, the Ministry of
food, agriculture and fisheries and the European Commission itself tend to create their own label guidelines to take into consideration other...
Since January 2008, the fishing agreements between the European Union and ACP (African, Caribbean, Pacific) countries have changed to comply with WTO rules and improve the management of the fisheries. However, the poor countries depend perhaps too heavily on foreign aids to impose any management system to the distant water...
Vertical mergers are mostly perceived in the literature as a way of reducing production and transaction costs.
However, vertical restrictions or raising rivals’ costs (RRC) are taken into great consideration by the antitrust authorities as
potential consequences of vertical integration. The case of the French tuna industry seems of particular...
