Resumo: | General introduction: The setting up of monitoring networks for coastal water quality of the REPHY type by IFREMER was taken from a public health standpoint and fits broadly in with a principle of precaution regarding eating shellfish meant for human consumption. The benefits to be compared with the costs of managing the REPHY network (estimated at FF7.4 million in 1995) are therefore first and foremost the reduction of the risk of poisoning and can be captured by subtracting the sanitation costs that are associated with them. Evaluating these direct benefits is, however, no easy task. The network leads in fact to the reduction of occurrences of poisoning such that the epidemiological data on which such a calculation should be founded diminishes over time. The presence of the network generates, in addition, indirect benefits in terms of derived use from the consumption of safer products. Nonetheless, consumers not being the explicit recipients of the information produced, it is therefore difficult to measure their approval of paying for increased security and therefore a network that many do not yet know exists. The assessment of the benefits presented in the first part focus, for this reason, on the direct benefits, with an appeal to dose-response functions that came out of international epidemiological data concerning mortality and morbidity linked to poisonings by phycotoxins.  However, beyond these direct benefits, the existence of such networks affects many players through the temporary sale restrictions to which they may lead. The intermediate report made it possible to discover these effects in as broad a manner as possible from producers, distributors and tourism professionals, while arguing for finishing in favour of an analysis targeting the players most directly affected, to wit, the producers.  For all that, an impact analysis limited to the measurement of sanitary benefits made possible by the network and the costs imposed on producers during sale restrictions would not exhaust the wealth of material of this subject. Just as important, indeed, this network, beyond the guarantee of non-toxicity, produces information on production conditions. This information is essentially intended for regulatory authorities in order for them to make decisions concerning consumer protection. But they lead, beyond that, to a change in the very functioning of the market of the products concerned. The decrease in sanitary risks can thus make possible a greater efficiency in exchanges by reducing the uncertainty attached to the consumption of such products. The guarantee of quality can translate into an increase in sale prices and a development of customer loyalty for the producers. The information produced by such monitoring networks therefore generates behaviour modifications and decisions that have great economic effects that are worth documenting. Measuring the economic impact of setting up such monitoring networks must therefore necessarily incorporate these various elements. The first part will make it possible to assess the direct benefits expected from the reduction of sanitary costs associated with poisoning, the second will make it possible to assess the costs associated with sale restrictions and the changes of operating conditions of the market analysed.
