Pêche récréative et risques sanitaires : le cas des coquillages

La pêche à pied est une activité récréative importante pour les zones littorales, notamment de l'Ouest de la France, mais mal connue. L'analyse des réactions des pêcheurs à pied face aux risques encourus par des changements de qualité des eaux permet de fonder une estimation de la valeur de ce loisir et de chiffrer le préjudice qu'ils peuvent subir lors d'une dégradation du milieu. L'application de la méthode d'évaluation contingente, avec les coûts de déplacement comme véhicule de paiement, fournit une mesure pertinente de cette valeur. L'analyse permet également de s'interroger sur le comportement du public vis-à-vis de l'information sur ces risques ainsi que sur la pertinence de la politique publique en matière d'information.

The sum of all the fears: the role of attitude towards health and environmental risks in the WTP a premium for organic foods

Many empirical studies underline that the main reasons for purchasing organic foods are the protection of health and environment and that the organic price premium is one of the major barriers to their consumption. These studies also show that there is a strong heterogeneity of these organic premiums as well as the Willingness To Pay (WTP) an organic premium. However, it is clear from these studies that there is no consensus concerning the determinants of these WTP. This article focuses on the question of the formation of these WTP an organic premium when the consumer decides to commit himself in a long-lasting consumption of organic foods to protect his health and environment. Using a dynamic analysis framework, we show that there is not one but several WTP and their determinants are a synthesis combining the consumer's characteristics but also his fears on the environmental impact of conventional agriculture as well as his fears about how a regular consumption of conventional food directly affects his life expectancy. We also show that the price barrier should be analyzed dynamically: for a consumer, the same price of organic foods may initially dissuade him from consuming organic foods but not necessarily throughout his life

Recreational shellfish harvesting and health risks: A pseudo-panel approach combining revealed and stated preference data with correction for on-site sampling

International audienceThis paper assesses the value of health risks related to recreational shellfish harvesting. Combining revealed and stated preferences data from an on-site survey and using a pseudo-panel approach shows that people significantly value health risks. The combination of stated and revealed preferences data is realised through the introduction of the concept of a “hypothetical twin site”. Addressing on-site sampling issues within the framework of a random-effect Poisson gamma model allows a derivation of more accurate estimates of welfare measures. Results also suggest that the demand for recreational shellfish harvesting is an inferior good

La somme de toutes les peurs : le rôle de l'attitude face aux risques sanitaires et environnementaux dans le CAP une prime pour les aliments biologiques

Impacts des enjeux environnementaux sur une politique de distanciation sociale optimale face à la pandémie de Covid-19

The 2020 Coronavirus COVID 19 pandemic has brutally confronted most national governments with a dilemma between fighting the pandemic and maintaining the economic activity. In a very short time, in the absence of effective vaccines and antivirals, they had to think about the implementation of a social distancing policy the least damaging for the economic activity by defining both its magnitude and its timeline. Depending on the priorities displayed by governments between preserving the economic activity and fighting the spread of the pandemic, social distancing policies can vary significantly. However, it was quickly observed that a social distancing policy has also had immediate positive environmental effects linked to the deep fall in the economic activity. This article models how the degree of environmental awareness in public decision-making acts on the optimal social distancing policy. The main conclusion is that higher consideration by the public authorities of the negative environmental effects generated by the economic activity can consolidate a social distancing policy against the pandemic

The sum of all the fears: the role of attitude towards health and environmental risk in the WTP a premium for organic foods

Many empirical studies underline that the main reasons for purchasing organic foods are the protection of health and environment and that the price premium associated with organic foods is one of the major barriers to consumption of these products. These studies also show that there is a very strong heterogeneity of these organic premiums as well as the Willingness To Pay (WTP) an organic premium. However, it is also clear from these studies that there is no consensus concerning the determinants of these WTP for organic foods. This article focuses on the question of the formation of these WTP a price premium for organic foods when the consumer decides to commit himself in a long-lasting consumption of organic foods in order to protect his health and environment. Using a dynamic analysis framework, we show that there is not one but potentially several WTP a price premium and their determinants are a synthesis combining the characteristics of the consumer (e.g. income, life expectancy) but also his fears on the environmental impact of conventional agriculture as well as his fears about how regular consumption of conventional food directly affects his own life expectancy. We also show that the price barrier should be analyzed dynamically: for a consumer, the same price of organic foods may initially dissuade him from consuming organic foods but not necessarily throughout his life
