We propose a technique derived from Heckman (1976) to accurately measure the expected increase in water use due to access to tap water while controlling for differences in characteristics between connected and non-connected households. Illustration is made on a cross section of 246 households from Dakar, Senegal. We show that getting a tap connection induces an expected increase in water use of 26 L per capita per day.

The simultaneous presence of two natural assets (the Seine river and the Vernier marshland) makes this analysis more complex. Our results show that the presence of Seveso-classified industries near dwellings strongly depreciates selling prices, yet this effect was not accentuated by the September 2001 explosion of the AZF factory in Toulouse. We also show that the proximity of natural assets, far from offsetting the negative presence of the petrochemical parks, steepens the price decline.

A partir d'un modèle simple, dans lequel la fonction de probabilité individuelle dépend de la quantité consommée, nous démontrons que l'endogénéisation du risque déforme les préférences du consommateur et conduit à une non-convexité des préférences. Les équilibres de consommation et les fonctions de demandes qui en résultent en sont singulièrement affectées, notamment selon le degré de sévérité perçu et selon la forme de la fonction subjective Quantité-Probabilité utilisée par le consommateur. Ce modèle cible en particulier les comportements face à des risques se réalisant à brève échéance après la consommation comme par exemple les risques de toxi-infections d'origine alimentaire.

This paper addresses the drivers of investment in the French commercial fishing fleets operating along the Atlantic coast, and the role of public policies have had on investment. First, we examine the changes in the capital value of the fleet, which was strongly impacted by decommissioning schemes during the nineties. We then examine drivers of investment using an unbalanced panel data set describing the investment decisions of a sample of firms over the period 1994-2004. In addition to economic variables, the estimated models account for other factors that may have an impact on investment behaviour, including the different career phases of the skipper-owners. The study concludes with a discussion of the results, and in particular of the role of fiscal policy on observed investment strategies.

For a vessel exiting a fishery, there may be several reasons including decommissioning, selling or operating elsewhere. Entry may be related to new vessels, or to vessels transferring from other fisheries. Modelling the behaviour of fishers with respect to their entering and exiting strategy can inform as to the impact of a proposed management policy and other external factors (e.g. changes in market, fuel costs and stock size), which can have major impact on the structure of fishing fleets. Three European cases studies are considered to understand the determinants of the observed changes in fleet size relating to such factors. In each case, a multinomial (unordered) logit model is used as the basis for analysis. Case studies considered include the Basque trawl fleet operating in the Bay of Biscay, the French 16-20m trawler fleet based in ports of Southern Brittany, and the English beam trawl fleet operating in the North Sea. Results confirm that in addition to individual vessel characteristics, both expected revenues and the additional incentives provided by decommissioning schemes have a bearing on a vessels' participation in a fishery.
