To examine whether four pre-selected front-of-pack nutrition labels improve food purchases in real-life grocery shopping settings, we put 1.9 million labels on 1,266 food products in four categories in 60 supermarkets and analyzed the nutritional quality of 1,668,301 purchases using the FSA nutrient profiling score. Effect sizes were 17 times smaller on average than those found in comparable laboratory studies. The most effective nutrition label, Nutri-Score, increased the purchases of foods in the top third of their category nutrition-wise by 14%, but had no impact on the purchases of foods with medium, low, or unlabeled nutrition quality. Therefore, Nutri-Score only improved the nutritional quality of the basket of labeled foods purchased by 2.5% (-0.142 FSA points). Nutri-Score’s performance improved with the variance (but not the mean) of the nutritional quality of the category. In-store surveys suggest that Nutri-Score’s ability to attract attention and help shoppers rank products by nutritional quality may explain its performance.

Projet EuroCod; International audience; We investigated consumer preferences for wild and farmed fish in an experiment with 276 participants in France. The experiment consisted of three rounds each round included a survey, sensory trials, and bidding. The survey results indicate consumers (1) perceive wild fish best for safety and health and farmed fish best for environmental sustainability and fish welfare; (2) rank salmon the highest on many attributes; and (3) prefer wild fish originating from the North Atlantic to farmed fish from France and northern Europe, and they rank farmed fish originating from developing countries lowest. In the sensory trials, salmon received the highest hedonic scores, followed by monkfish and cod, while pangasius scored significantly lower. Willingness to pay for salmon was almost as high as for monkfish and higher than for cod, while WTP for pangasius was substantially lower.

Driven by economic development and urbanisation, animal-based protein (ABP) consumption has surged worldwide over the last 50 years, rising from 61 g per person per day in 1961 to 80 g per person per day in 2011. This contribution analyses the apparent convergence of dietary models worldwide with respect to the proportion of ABP and especially meat in intake. By using FAO data for 183 countries over the period 1961–2011, the authors show the connection between annual per capita GDP and the level of ABP (R2 = 0.62) and meat consumption (R2 = 0.62). They emphasise the surge in ABP intake in emerging countries (China, Brazil) which has partly replaced plant protein. However, for similar degrees of economic development, the composition of ABPs and the position of meat within this category vary significantly among countries, suggesting that historical, geographical, cultural and religious factors may be involved.

Code JEL : C91, D12, Q01, Q13; International audience; Using experimental auctions carried out on apples in different European countries, this paper contributes to the assessment of consumer willingness to pay for the reduction of pesticides. We study several systems of good agricultural practices, possibly signalled to consumers, ranging from Integrated Pest Management certifications to organic production methods. The results show a relatively homogeneous behaviour of European consumers and reveal that improving the information on pesticide reduction may have unintended consequences. Results also suggest that taste characteristics and reference to a Protected Denomination of Origin should not be overlooked.

Resume Ce chapitre presente quelques exemples des actions conduites au plan national pour ameliorer l’offre alimentaire et favoriser une evolution vers une plus grande adequation aux recommandations nutritionnelles et alimentaires du PNNS. Ces actions concernent l’offre alimentaire originelle (allaitement) jusqu’a l’offre alimentaire proposee par les operateurs economiques (a travers les chartes d’engagements de progres nutritionnels) et certains aspects de sa regulation (messages sanitaires accompagnant les publicites), en passant par l’offre alimentaire en restauration collective publique, qui inclut notamment l’offre alimentaire a l’ecole. Les efforts deployes au cours du PNNS2 vers les populations defavorisees sont egalement presentes, illustrant les liens qui peuvent se creer avec d’autres programmes de sante publique, comme le programme Alimentation et insertion (presente ici) ou le programme Bien vieillir. Enfin, les Pouvoirs Publics ont recemment mis en place un outil unique et original pour permettre de suivre et quantifier ces evolutions, l’Observatoire de la qualite de l’alimentation, dont les methodes et les premiers resultats sont resumes, soulignant leur interet pour l’evaluation du PNNS.

Resume A partir de l’analyse des crises de subsistance, qui illustre la question cle de l’equilibre entre la consommation et les ressources, les travaux des economistes ont mis en evidence les effets determinants de l’augmentation de la productivite agricole sur le niveau, puis sur la composition de la ration alimentaire. La baisse continue des prix des aliments a permis l’amelioration du statut nutritionnel du plus grand nombre mais elle a egalement des effets paradoxaux : surconsommation dans les pays developpes et malnutrition dans les pays pauvres ou en transition. Les economistes s’efforcent de proposer des actions pour resoudre ces problemes. Favoriser le developpement agricole local apparait de plus en plus comme une voie a privilegier pour remedier a l’eviction des petits producteurs, premieres victimes de la sous-alimentation. Pour enrayer la progression du surpoids et de l’obesite, des interventions sur l’environnement des choix alimentaires, inspirees de l’economie comportementale, sont proposees pour completer les actions economiques classiques par le biais de l’information et des prix.

Combris@ivry.inra.fr; International audience; Purpose – To survey consumers living in Paris, France, to determine the extent to which they use nutrition labels, and to determine the percentage of French consumers who use nutrition labels, how often they use nutrition labels, and how they would like to see current nutrition labels improved. The researchers also wanted to determine the reasons why consumers do not use nutrition labels, and to try and assess users' and non-users' perceptions about mandatory nutrition labelling. Design/methodology/approach – French consumers (n = 355) were surveyed in supermarkets in Paris and its suburbs, using a 21-item questionnaire in May 2004. Interviewers used questionnaires to assess the frequency of respondents' nutrition label use, to investigate the specific nutrient information most commonly consulted on nutrition labels, the types of products on which consumers most often tend to consult nutrition labels, and to collect demographic information. Findings – Only 45.1 per cent of the sample reported reading nutrition labels, with the majority of consumers reading labels only occasionally. Non-label readers cited lack of interest as the primary reason why they do not read labels, but 95 per cent of the sample, when asked about mandatory nutrition labeling, felt that nutrition labeling should be required of food manufacturers. Research limitations/implications The sample size was small, participation was voluntary and was limited to the city of Paris and its suburbs, and therefore cannot be generalized to the French population. Originality/value – This is the first study to collect data in a point-of-purchase setting in order to examine whether or not French consumers use nutrition labels.

This study was conducted to assess how the Fairtrade label interacts with the perception of intrinsic product characteristics on liking and purchase decisions and to estimate the evolution of this interaction after exposure to the coffees and/or exposure to ethical information. In a first session, 119 consumers gave liking scores for 2 regular and 2 Fairtrade coffees under a blind tasting condition. Then, they were asked to indicate the maximum price they would pay for each product in 2 auctions taking place under different information conditions. In the first auction, participants saw the packaging but did not taste the coffee; in the second auction, they could both taste the coffee and see the packaging. After the first session, the consumers were randomly split into 4 groups, and these groups were exposed for one month to different conditions before returning to the lab for exactly the same measurements as in the first session. The first of the 4 groups was not exposed to sensory characteristics or ethical information. Each consumer of the second group was only exposed to sensory characteristics of the coffees (one packet of his/her least liked regular and ethical coffees delivered in blind packaging for home consumption). The third group was exposed to sensory characteristics and ethical information (the same as the second group but using the original coffee packaging showing fair trade information). The final group was only exposed to ethical information. Results showed that the hedonic scores of the least liked ethical and regular products increased from session 1 to 2, but not significantly more when consumers were exposed to these products between the sessions. However, while consumers offered lower prices for ethical products at the first session, those who were exposed to ethical information increased their willingness to pay for ethical products. This effect became statistically significant when consumers could taste the products before making their bid. The effect of exposure to ethical information was also transferred to the willingness to pay for the ethical product to which the consumers were not exposed. This study highlights the interest of a design, which makes it possible to assess the impact over time of sensory and external information on the willingness to pay.

hal-00950490, version 1; International audience; Consumer preferences for different variants of a given food product can be directly obtained with hedonic measurements or revealed with willingness-to-pay measurements. The aim of this paper is to present a comparison of the data collected using these two types of measurements on four data sets collected in our laboratory for different food products (bread, cooked ham, cheese and orange juice). This comparison was conducted at two levels (global and individual) and was based on two criteria: discrimination between variants and consistency in variant ranking. For the four data sets, hedonic measurements and willingness-to-pay measurements were collected for each participant in a 'full information' condition, i.e. in a condition where participants tasted each variant associated with extrinsic information. To reveal consumer willingness-to-pay, the BDM mechanism was used (Becker, DeGroot, & Marschak, 1964), which consists in real sales at a random price. Aggregate results were similar for the two measurements. In addition, in two out of four studies, willingness-to-pay measurements led to slightly higher discrimination between variants than hedonic measurements. At the individual level, more inconsistencies were found. This result is in line with previous studies. Nevertheless, participants were more consistent concerning the most-liked variant than concerning the least-liked variant. Our results also showed that hedonic score distributions did not reveal any cut-off point below which consumers chose the no-purchase option; this cut-off point largely depended on individuals and products.

International audience; Cet article rend compte d'une étude menée afin de comparer le comportement des consommateurs qui doivent choisir des produits sous contrainte économique, selon deux conditions différentes : quand la qualité perçue est basée sur une attente générée par des images fabriquées et, à l'inverse, quand la qualité perçue est basée sur l'expérience sensorielle en présence d'images fabriquées. Les participants de l'expérience ont été choisis au hasard, dotés d'un budget réel et placés dans cinq situations différentes de prix/budget. Ils ont formulé leurs choix parmi six jus d'orange dans chaque situation prix/budget. Ce travail a été réalisé pour les deux conditions différentes d'information. Les résultats montrent que les participants qui choisissent les produits sans les goûter font leur choix plus rapidement, ils choisissent un grand nombre de variables et leurs choix tendent à être moins influencés par les critères de goût, comme c'est le cas pour les participants qui choisissent les produits après les avoir goûtés. La comparaison entre ces deux conditions permet de comprendre les différences de comportement des consommateurs selon qu'ils étaient en situation d'information totale ou restreinte.

The aim of this study was to compare consumer choices observed in a real choice experiment and their reservation prices elicited with the BDM mechanism in order to assess the rationality of participant behaviors. One hundred and seventy-seven participants tested four French baguettes in each task. For the real choice experiment, participants were faced with 17 scenarios (17 × 4 baguette-price combinations). In each method, participants could select a “no purchase” option. Comparing choices and reservation prices made it possible to assess the rationality of participant behaviors. From a strict economic standpoint, 50% of observed choices were fully rational. When one baguette was actually chosen, the main choice strategy was preference maximization (42.2%), followed by price minimization (26.2%), and then by the combination of both (10.5%); the remaining choices (21.1%), for which no clear strategy could be found, were considered puzzling.

Ce document de travail a pour objet l'application de la technique des prix hédoniques au vin de Bordeaux. Les auteurs considèrent, dans la fonction de prix hédoniques, non seulement les principales caractéristiques "objectives" (classement, millésime, appellation), mais également de nombreuses caractéristiques sensorielles. Les données sont issues d'une étude expérimentale au cours de laquelle trois jurys, composés d'oenologues et de sommeliers, ont évalué et noté un échantillon de vins de Bordeaux. Les vins sont dégustés à l'aveugle, de façon à ce que les membres des jurys ne soient pas influencés par les informations données par l'étiquette de la bouteille, l'aspect visuel du vin ou par le prix de la bouteille. L'estimation de la fonction de prix hédoniques montre que le prix de marché est essentiellement déterminé par les caractéristiques objectives, et en particulier par le classement du vin. Les auteurs régressent par ailleurs la note des experts sur les caractéristiques du vin, la note attribuée par un jury pouvant être considérée comme un indicateur de la qualité d'ensemble d'un vin. Il en ressort que la note des experts, à la différence du prix du marché, est essentiellement déterminée par les caractéristiques sensorielles. Les implications possibles de ces résultats pour la structure du marché de vins de Bordeaux sont discutées.

Patrice BERTAIL and Pierre COMBRIS
- Abstract
The generalized bootstrap, introduced by Lo [1991] and further by Mason and Newton [1992] is applied to survey sampling. The idea is to choose adequate random weights (or resampling plans) so as to imitate the initial fluctuations of the probability sampling, maybe taking into account the priorities of the survey statistician, to obtain an estimator of the distribution of the statistics. The method is applied to the construction of confidence intervals for means, ratios and fractiles of food consumption data from the household panel surveys of Secodip.

Analysis of the medium- and long-term evolution of global food consumption highlights sorne striking regularities. This chapter addresses the potential consequences of a generalisation of the se trends, before focusing on their determinants and in particular the factors that might alter current trends to promo te grea ter sustainability. Six main areas are covered: the characteristics of long-term changes to diet, the international convergence of food models and evolution of the situation in Southern countries, the bio-physiological determinants of changes to consumption, the role of agricultural policies, the identification of factors that may change trends and, finally, the heterogeneity of consumption and nutritional inequalities. One of the major issues addressed by this working group was to determine whether dietary trends and their underlying major determinants were the same in all countries, or whether on the contrary it was possible to identify differences that might indicate alternative pathways for change. The same concern led the group to look at break points in past consomption trends, concerning meat in particular, insofar as they might le ad to a clearer understanding of the mechanisms underlying the alteration of long-term trends and the emergence of new dietary standards.

Ever-increasing international competition in the wine sector has sharpened the controversy among economists who are in charge of analysing the agricultural sector and regional development. The growth of exports from the so-called New World countries (Australia, South Africa, Chile, Argentina, United States) questions rural concepts of wine-growing economy and makes it necessary to reconsider consumers’ expectations and the whole economic organisation and marketing strategies of the wine sector.

Le groupe de travail « SHS et santé » de l’alliance Athéna est chargé d’une mission anticipatrice portant sur les thématiques de Sciences Humaines et Sociales concernant la santé afin de stimuler et faire évoluer la recherche de SHS sur ce domaine, et d’en assurer l’ouverture internationale. Ce travail de prospective vise tout à la fois à énoncer des recommandations de l’alliance Athéna en direction de l’ANR et à doter l’alliance d’orientations et d’actions dans ce domaine pour sa propre stratégie scientifique et pour a nourrir les échanges avec ses partenaires, notamment l’alliance Aviesan.Selon une approche de type matriciel, le groupe a identifié 4 lignes de questionnement sur des thèmes qu’il a définis comme prioritaires et décidé de privilégier 3 axes problématiques transversaux, susceptibles de s’appliquer à chacun de ces 4 thèmes. Ces 4 lignes de questionnement portent sur :1 - La question des risques, au travers de l’analyse des interactions et tensions entre risquesindividuels et collectifs ou sociaux.2 – La question des handicaps et plus généralement des restrictions de l’activité et de laparticipation sociale au cours de la vie et leurs réponses biologiques, médicales et sociales.3 - Les interrogations ouvertes par les biotechnologies autour de l’innovation et de latransformation des savoirs, des pratiques et des métiers.4 – Les enjeux portés par les transformations des formes d’organisation du système de santéet de la sphère médico-sociale.Dans une perspective de problématisation plus transversale visant à identifier des concepts,des procédures ou des mécanismes comparables, transférables ou similaires, il s’agira pourchaque thème de regarder plus spécifiquement : 1) les formes d’interaction entre acteurs quiles structurent ; 2) les dispositifs et modalités d’évaluation et de régulation qui sont mobilisésainsi que les systèmes de règles et de normes produites ; 3) et enfin les enjeux en termed’égalité ou d’inégalité individuelle, collective, internationale.Ont participé à ce rapport : Sophie Béjean, Martine Bungener, Madeleine Akrich, Simone Bateman, Juliette Bloch, Christian Bonah, Philippe Casella, Chantal Cases, Maurice Cassier, Jean-Pierre Poulain, Didier Torny, Isabelle Ville, Laurent Vidal, Pierre Combris, Pierre Demeulenaere et Archana Singh-Manoux.

Consumers’ food decisions are based on the information they receive and on their own individual characteristics. This paper is based on an experiment using experimental economics and sensory evaluation to measure individual characteristics of participants and to analyze the impact of nutritional information relative to orange juice. The aim is to explore the potential link between specific characteristics (risk aversion, time preference) and the reactions of consumers to nutritional information. The results show that participants react significantly to this information supplied, positively for the pure orange juice and a negatively for orange nectars. In addition, “risk averse” individuals appear more sensitive to information that “risk neutral” ones. Similarly, individuals with a preference for the future show sharper and more stable responses to information about the products than those who prefer the present., Les consommateurs prennent leurs décisions alimentaires en fonction des informations qu’ils reçoivent et de leurs caractéristiques individuelles. Dans le cadre d’une expérience associant économie expérimentale et évaluation sensorielle, nous mettons en parallèle l’évaluation d’informations nutritionnelles relatives aux jus d’orange et la mesure de caractéristiques individuelles des participants. L’objectif est d’explorer le lien potentiel entre des caractéristiques rarement mesurées (aversion au risque, préférence pour le présent) et les réactions des consommateurs aux informations nutritionnelles. Les résultats montrent que les participants réagissent significativement aux informations nutritionnelles qui leur sont fournies, de façon positive pour les purs jus d’orange et de façon négative pour les nectars d’orange. Par ailleurs, les individus « averse au risque » réagissent plus à l’information que les individus « neutre au risque ». De même les individus ayant une préférence pour le futur réagissent de façon plus nette et plus stable à l’information sur les produits que ceux préférant le présent.

Période 2000-2012. http://prodinra.inra.fr/record/256699; International audience; The aim of this study was to explore the effectiveness of a food-labeling strategy to introduce new versions of foods to children's diets, in natural lunch settings (school canteens). The proposed food involved two different types of vegetables: carrots (very familiar) and broccoli (less familiar), both being prepared and presented for choice in a 'familiar' (known) versus a 'new' (unknown) version. We assessed whether adding a label (either basic or model-related) to new versions of vegetable dishes would increase the likelihood that 8- to 11-year-old children would select the new dishes rather than the familiar versions. In the first condition (no label/control condition), both the familiar and the new versions of the vegetable dishes were presented with absence of any information. In the second condition (basic label condition), the new dish was presented accompanied by a basic label: "new carrot/broccoli recipe". In the third condition (model-related label condition), the new version of the dish was presented with a model-related label: "new carrot/broccoli recipe, Special Mix for Super Heroes". Results showed that children chose significantly more often the familiar version of the dish when no information was given (control condition). The addition of a descriptive label (whether basic or model-related) led to an increased frequency of choice for the new vegetable dish for carrots only, and not for broccoli. This study suggests that adding a label with the vegetable's name can be used to increase children's willingness to select a new version of a vegetable dish instead of a familiar one, at least when the vegetable is familiar to the children (i.e. carrots).

Période 2000-2012. http://prodinra.inra.fr/record/256699; The present study investigated the visual and lexical knowledge of vegetables in children. The purpose of this was to identify both liked and disliked familiar vegetables which will be used in a further study. We explored children's lexical knowledge with a free listing test and their visual knowledge with a picture's sorting test. 145 children between the ages of 8 and 11 years from various living environments of the Rhône-Alpes Region, France, completed both tests. Overall, 54 vegetables were cited, 16 of which were cited by more than 9% of the sample. Carrots, tomatoes and lettuce were the most named vegetables and the best visually recognized by children. Lexical knowledge increased gradually with age. Children from rural areas named significantly more vegetables than those from urban areas. However, visual recognition of vegetables did not change as a function of age or living environment. This suggests that visual categorization allows easier accessing to semantic knowledge than verbal questioning. Finally, the data showed a relation between visual familiarity and liking: the majority of raw vegetables recognized visually were also classified as “liked vegetables”. In addition, children declared that they did not want to try most of the unknown vegetables. We explore the vegetable category in 8-to-11-year old children. We analyse the category with lexical and visual accesses. Children's vegetables naming increase with age but not according to age or gender. Visual recognition does not change as a function of age or living environment. Data show a relation between visual familiarity and liking.

International audience; Background/Objectives:To assess developments in the nutritional quality of food products in various food groups in France, an Observatory of Food Quality (Oqali) was created in 2008. To achieve its aims, Oqali built up a new database to describe each specific food item at the most detailed level, and also included economic parameters (market share and mean prices). The objective of this paper is to give a detailed analysis of the monitoring of the ready-to-eat breakfast cereals (RTEBCs) sector in order to show the benefits of the Oqali database. Subjects/Methods: Analysis was limited to products with nutritional information on labels. Packaging was provided by manufacturers or retailers, or obtained by buying products in regular stores. Economic parameters were obtained from surveys on French food consumption and data from consumer purchase panels. The breakfast cereal sector was divided into 10 categories and 5 types of brand. Oqali has developed anonymous indicators to describe product characteristics for each category of RTEBC and each type of brand by cross-referencing nutritional values with economic data. Packaging-related data were also analysed. The major nutritional parameters studied were energy, protein, fat, saturated fat, carbohydrates, sugars, fibre and sodium. Analysis was performed on the basis of descriptive statistics, multivariate statistics and a Kruskal–Wallis test. Results: For the RTEBC, there is large variability in nutrient content throughout the sector, both within and between product categories. There is no systematic relation between brand type and nutritional quality within each product category, and the proportion of brand type within each product category is different. Nutritional labels, claims and pictograms are widespread on packages but vary according to the type of brand.Conclusions:These findings form the basis for monitoring developments in the nutritional composition and packaging-related data for breakfast cereals in the future. The final objective is to expand the approach illustrated here to all food sectors progressively.

Study design: The French Observatory of Food Quality was created by the Government for the quantification and follow-up of food reformulation by the food industry. This nutritional composition database on branded products was matched with two consumption databases: TNS Kantar Worldpanel, which provides details on quantities bought and food expenditures; and INCA 2, an individuals’ food consumption survey completed by the French Food Safety Agency. Three food groups were considered: breakfast cereals (355 items in 2008), biscuits and pastries (1805 items in 2008), and bread-based products (620 items in 2009). Methods: First, the variability in nutrient composition within food categories was determined, which made it possible to consider several food composition modification scenarios within each category. The formulation of the food items with the lowest nutritional quality was modified to three different levels to improve the overall level of quality in a given category. Second, the quantities of sugars, fat, fibre and sodium delivered to the French market through breakfast cereals, biscuits, pastries and bread-based products were calculated for each scenario. Finally, the distribution of individuals’ nutrient consumption from the three food groups among the French population was assessed. Results: These scenarios generated important improvements of 1–22% (increase in the amount of fibre or decrease in the amounts of sugars, fat and sodium delivered to the market), depending on the scenario, the food group and the nutrient considered. Improvement of the products with the lowest nutritional quality would also lead to significant variation in individuals’ nutrient consumption for the average adult and child consumers of the three groups (range 4.2–18.8%, depending on the scenario, the food group and the nutrient considered). Conclusion: Encouraging the reformulation of foods, especially for products with the lowest nutritional quality in each category of processed foods, is a worthy target for health policy makers. The methodology presented in this paper provides information for negotiations between policy makers and firms to quantify commitments in terms of their potential impacts on individuals’ nutrient intake, and to check that the firms’ commitments are actually met.

The ELPAS (Etude Longitudinale Prospective Alimentation et Santé) study was an 8-month randomized controlled dietary modification trial designed to test the hypothesis that family dietary coaching would improve nutritional intakes and weight control in 2026 free-living children and parents. It resulted in significant nutritional changes, with beneficial effects on body mass index in adults. In these ancillary analyses, we investigated dietary changes throughout the intervention.Before the study, modeling analyses were carried out on the French Association Sucre Produits Sucrés Consommation et Communication (ASPCC) food-consumption database to identify the most efficient dietary intervention strategy. During the study, all participants performed monthly three nonconsecutive 24-h dietary recalls: this allowed for measuring changes in the number of servings per day and serving size for each targeted food category throughout the intervention.Modeling analyses showed that targeting only the 10 main foods contributing to fat and carbohydrate intakes did not allow for reaching the ELPAS nutritional goals. As a result, it was decided to target more foods and to propose several types of dietary advice (such as change in serving size, change in cooking method, food substitution). This strategy led to many appropriate dietary changes during the intervention, but only a few of them reached significance. The mean number of servings per day was indeed significantly modified for only 7% of the targeted food categories in children and 17% in parents. The mean serving size was modified for only 12% of targeted food categories in children and 9% in parents.The cumulative effect of small dietary changes may induce significant nutritional improvements, with limited burden for populations.

Strukturelle Änderungen: der Fall des Lebensmittelkonsums in Frankreich zwischen 1949 und 1988, von Pierre Combris. Die Analyse der Konsumentwicklung iiber einen längeren Zeitraum hinweg wirft die Frage der Änderungen des Verbraucherverhaltens auf. In diesem Artikel wird die Stabilität der disaggregierten Funktionen der Nachfrage der Haushalte zwischen 1949 und 1988 analysiert. Der Schwerpunkt liegt hierbei auf den Lebensmitteln, insbesondere auf dem Bruch mit den Gewohnheiten beim yerbrauch von Fleisch, das in Nordamerika und in Australien immer mehr Gegenstand von Diskussionen ist. Fälle von Änderungen bei den Verbraucherpräf erenzen sind, wie es scheint, unbestreitbar., Structural Changes: The Case of Food Consumption in France from 1949 to 1988, by Pierre Combris. Analyzing changes in food consumption over a long period of time poses the problem of accounting for behavioural change. This paper analyses the stability of household demand functions estimated on an annual time series, using the French National Accounts data from 1949 to 1988. Particular attention is paid to food consumption, and to the existence of structural change in meat consumption, about which a debate is developing in North America and Australia. There is clear evidence that tastes have changed according to the findings of this report., Changements structurels : le cas des consommations alimentaires en France de 1949 à 1988, par Pierre Combris. L'analyse de l'évolution de la consommation en longue période pose le problème des changements de comportement. Ce texte analyse la stabilité des fonctions de demande des ménages, désagrégées, de 1949 à 1988. Une attention particulière est portée aux produits alimentaires, et notamment aux ruptures dans la consommation des viandes, à propos desquelles un débat se développe en Amérique du Nord et en Australie.

International audience; The purpose of this paper is to illustrate how sensory and experimental economics techniques can be combined in protocols for investigating the influence of food product characteristics and information on consumers’ preferences. Preferences are measured through willingness to pay (WTP) which is elicited by means of incentive mechanisms including real sales of the tested products. After a quick review of incentive mechanisms used in experimental economics, the protocol is described and illustrated by examples from different studies on WTP for wines.

International audience; The objective of this study was to assess the impact of nutritional information on the willingness to pay for bread. Four French baguettes were presented to 123 consumers who firstly gave liking scores in three evaluation conditions, and who then gave their maximum price (reservation price) they were ready to pay in two information steps. In the first step, the baguettes were presented without any information about their composition. Following this, half the participants received information about the potential health benefits of fibre. In the second step, two baguettes were presented with a ‘source of fibre' label. A similar product hierarchy was observed between hedonic scores and reservation prices. In addition, a significant effect was found on the reservation prices when the ‘source of fibre' label was presented, but no effect was observed when the information concerning the potential health benefits of fibre was given.

Two randomly sampled groups of subjects were endowed with real budgets and placed in 5 different budget/price situations. In each situation they had to evaluate 6 orange juices and complete a demand table. At the end of the experiment, one demand table was randomly selected and participants had to buy the corresponding products. In one group, participants choose after looking at the packaging in the other they could also taste the products. Results show that participants who chose without tasting, made quicker decisions, selected a larger number of variants and were more influenced by prices than those who could taste the products. Although choices appeared very heterogeneous, most participants exhibit coherent behaviors. (JEL classification: C91, D12)

Until recently, fresh fruits such as pears were provided to markets as generic products. However, these products are now differentiated by cultivars, origins and appearances, as well as by companies production and processing methods. Therefore, we observe a lot of denominations of origin, retailers and private labels in order to signal the differentiation to the consumers, who are often willing to pay large price premiums for products with specific attributes. Indeed the value consumers put on fruits depends on the degree of product-information that are available to them and this information derives mainly from tasting and from the label of the products. In this paper, we used an experimental auction to investigate how quality attributes information affects consumers willingness to pay for different types of pears, particularly choosing the Portuguese "Rocha" pear variety. The BDM auction mechanism was combined with sensory analyses in order to develop an integrated approach to evaluate product attributes. The main results show that information on the products characteristics related to food safety instantly influences consumers willingness to pay. However, it appears that sensory intrinsic attributes related to taste finally beats the guarantee of food safety in driving the buying behaviour.

Nutrition and Dietetics ,Medicine (miscellaneous) - Abstract
Resume L’economie et la nutrition ont une histoire commune qui remonte au milieu du xviii e siecle, lorsque debute la reflexion sur la rationalisation de l’alimentation. L’elaboration des concepts permettant de quantifier les depenses energetiques et les besoins nutritionnels commence avec Lavoisier. Les connaissances se developpent tout au long du xix e siecle et conduisent a la notion d’alimentation rationnelle, un ensemble de principes pour satisfaire les besoins nutritionnels au moindre cout economique. Cette preoccupation apparait explicitement dans les tables de composition des aliments publiees a la fin du xix e siecle et dans les travaux qui en decoulent tout au long du xx e. Si l’idee de rationalite n’apparait plus guere aujourd’hui dans les travaux des nutritionnistes, elle reste la reference pour les economistes, qu’il s’agisse d’y adherer ou de s’en demarquer. L’economie de l’obesite, la justification et l’evaluation economique des interventions reposent sur l’idee de rationalite des choix individuels, qui est ensuite elargie pour integrer les biais comportementaux que le modele standard laisse de cote. Ce faisant, l’analyse economique aboutit a une evaluation plus complete des couts et des benefices des interventions visant a modifier les comportements. Ce type d’analyse, qui rend mieux compte des effets des politiques de sante, peut etre etendu aux impacts environnementaux, une demarche indispensable pour favoriser une alimentation durable.

- Abstract
Sur des marchés très segmentés où l'information joue un rôle considérable, l'estimation des consentements à payer pour des produits ayant des caractéristiques spécifiques est une question centrale. Les méthodes de l'économie expérimentale ont pour but d'inciter les individus à révéler leurs consentements à payer dans un environnement où l'apport d'information est contrôlé. Appliquées à différents types de produits (aliments contenant des OGM, vin, Champagne, …), dont on révèle progressivement les caractéristiques, ces méthodes permettent de comprendre la contribution de chaque caractéristique à la valeur globale attribuée aux produits testés. Elles permettent aussi de mesurer l'impact sur les choix d'un apport d'information sur les propriétés nutritionnelles ou sanitaires des aliments.

International audience; L'étude a été effectuée afin de comparer deux mécanismes destinés à révéler les préférences des consommateurs : une enchère Vickrey qui mesure la disposition à payer, et un test hédonique classique. A travers ces deux méthodes, l'objectif était d'estimer les effets respectifs des caractéristiques sensorielles et de l'information externe sur l'évaluation de cinq champagnes brut non millésimés. Cent-ving-trois consommateurs ont été assignés au hasard aux deux groupes et ont utilisé l'une des méthodes. Quelle que soit la méthode, ils ont évalué les champagnes à l'aveugle, puis sur la base d'une présentation des bouteilles et, enfin, après l'observation de la bouteille en une dégustation. Les résultats ont montré que les deux méthodes étaient équivalentes pour révéler l'effet de l'information externe sur l'ensemble de l'évaluation des champagnes. Les participants étaient incapables de distinguer les champagnes après une dégustation aveugle, alors que les différences signifiantes dans les préférences pour les produits apparaissaient quand les labels étaient connus. Les préférences respectaient la hiérarchie des prix du marché. Néanmoins, des différences entre les deux méthodes ont été observées suggérant que le choix de la méthode doit être fait en fonction des objectifs spécifiques de l'étude.

International audience; Comment expliquer les différences entre les prix des vins sur un marché ? Sur un marché de connaisseurs, la qualité du vin est l'élément déterminant dans l'explication des différences de prix. Dans le cas des grands vins, les grands crus de Bordeaux en particulier, les ventes aux enchères constituent un marché actif où interviennent des agents bien informés. On peut considérer que ce marché est un marché efficace. Par contre, l'inefficacité domine dès que l'on prend en compte l'ensemble des vins bénéficiant d'une appellation et pas seulement les grands crus. Il ne s'agit plus, alors, d'un marché d'experts, mais d'un marché de profanes. L'analyse des marchés d'acheteurs profanes doit donc être approfondie pour mieux comprendre les liens entre les prix et les caractéristiques des vins. C'est pourquoi, les auteurs ont entrepris de poursuivre cette recherche en appliquant aux vins de Bourgogne l'analyse réalisée antérieurement pour les vins de Bordeaux. Dans la fonction de prix hédoniques, les auteurs considèrent non seulement les caractéristiques "objectives" apparaissant sur l'étiquette de la bouteille, mais également les caractéristiques sensorielles du vin. L'estimation de la fonction de prix hédoniques montre que le classement reste la caractéristique la mieux valorisée par le marché. L'estimation de deux équations de note du jury montre que, contrairement au cas bordelais, le classement semble être un bon indicateur de qualité.

Knowledge of what determines consumer choices is essential for anyone who wants to have an idea of the foods of tomorrow. Basic determining factors include individual tastes and preferences, but because tastes, and even moreso product preferences are usually heterogeneous, and sometimes unstable, they are difficult to determine and predict. Behaviour, at least to a certain degree, is made predictable by the existence of nutritional, economic, temporal, social and other constraints.

- Abstract
Purpose ? To survey consumers living in Paris, France, to determine the extent to which they use nutrition labels, and to determine the percentage of French consumers who use nutrition labels, how often they use nutrition labels, and how they would like to see current nutrition labels improved. The researchers also wanted to determine the reasons why consumers do not use nutrition labels, and to try and assess users' and non-users' perceptions about mandatory nutrition labelling. Design/methodology/approach ? French consumers (n ?=? 355) were surveyed in supermarkets in Paris and its suburbs, using a 21-item questionnaire in May 2004. Interviewers used questionnaires to assess the frequency of respondents' nutrition label use, to investigate the specific nutrient information most commonly consulted on nutrition labels, the types of products on which consumers most often tend to consult nutrition labels, and to collect demographic information. Findings ? Only 45.1 per cent of the sample reported reading nutrition labels, with the majority of consumers reading labels only occasionally. Non-label readers cited lack of interest as the primary reason why they do not read labels, but 95 per cent of the sample, when asked about mandatory nutrition labeling, felt that nutrition labeling should be required of food manufacturers. Research limitations/implications The sample size was small, participation was voluntary and was limited to the city of Paris and its suburbs, and therefore cannot be generalized to the French population. Originality/value ? This is the first study to collect data in a point-of-purchase setting in order to examine whether or not French consumers use nutrition labels. [ABSTRACT FROM AUTHOR]

- Abstract
The development of consumer associations and their impact on industrialists - The general subject of the relationship between agents in the food industry is tackled here from the particular angle of the action of consumer associations in France. After a brief outline of their history, showing that the phenomenon of « consumerism » has deep roots, the action of these associations is considered from three points of view : defence, information, representation of consumers. This action is then analysed from the point of view of its impact on earlier agents : the processing industries, professional circles and distributors. Although few studies have been carried out in this field, it is evident that modifications in the behaviour of firms are slight. The phenomenon principally affects the big firms which are able to adapt, and all the more so that marketing theorists work out new concepts that will enable the firms to take into account the consumers' long-term social aspirations., Le thème général des relations entre agents dans les filières alimentaires est abordé ici sous l'aspect particulier de l'action des associations de consommateurs en France. Après un bref rappel historique, qui montre que le phénomène du consumérisme a des racines déjà lointaines, les actions des associations sont abordées sous les trois angles : défense, information, et représentation des consommateurs. Ces actions sont ensuite analysées du point de vue de leur impact sur les agents de l'amont : les entreprises de transformation, les milieux professionnels et les distributeurs. Bien que peu d'enquêtes aient été menées dans ce domaine, on peut constater que les modifications de comportement des entreprises restent faibles. Le phénomène touche avant tout les grandes entreprises qui sont en mesure de s'adapter. Et cela d'autant mieux que les théoriciens du marketing élaborent de nouveaux conôepts qui permettront aux entreprises d'intégrer les aspirations sociales à long terme des consommateurs., Combris P., Hossenlopp J., Zitts Elise.

Fabriquer des aliments pour 54 millions de consommateurs, contribuer a l'equilibre des echanges exterieurs, proceder a d'importants processus de modernisation et de restructuration, tel est le role des industries agricoles et alimentaires. Cependant, ces industries ne se sont pas contentees de tirer parti de la hausse des revenus et de la demande croissante de produits alimentaires elabores; par leur effort de productivite, elles ont directement contribue a la diminution du cout de l'alimentation et donc a la hausse des salaires reels, jouant ainsi un role important dans le modele d'accumulation de l'apres-guerre. Ce resultat global n'empeche pas, bien evidemment, que la logique fordiste se soit developpee a des periodes differentes et surtout a des degres tres divers dans les differentes branches qui constituent les IAA.

- Abstract
This paper discusses the usefulness of the concept of agribusiness for economic research on food industry. In the mid-fifties in the USA, and in the mid-sixties in France, the concept of agribusiness was introduced to cope with problems relating to the evolution of agriculture. This concept turned out to be relevant to research on three different problems : insertion of agriculture in highly industrialized economies, industrialization of food, and development of capitalist relations of production in agriculture. To carry out the analysis of the accumulation of capital in industry, the concept of agribusiness seems to provide a good framework, especially explaining the specific characteristics of this sector (dominating agriculture, constraints on food prices). Actually, the use of the concept raises more theorical questions than answers., Ce texte étudie l'intérêt de l'utilisation du concept d'agro-alimentaire pour l'analyse économique des industries agricoles et alimentaires. Dès le milieu des années cinquante aux Etat-Unis, des années soixante en France, le recours au concept d'agro-alimentaire s'est progressivement imposé pour traiter des questions relatives à l'évolution de l'agriculture. Ce concept s'est avéré utile aux recherches dans le cadre de trois problématiques bien distinctes : celle de l'insertion de l'agriculture dans les économies industrielles développées, celle de l'industrialisation de l'alimentation, et enfin celle de la pénétration des rapports de production capitalistes dans l'agriculture. Dans le cas de l'analyse des modalités de l'accumulation des capitaux dans les industries agricoles et alimentaires bien que l'utilisation du concept d'agro-alimentaire paraisse aller de soi pour rendre compte des particularités de ce secteur (domination de l'agriculture et contrainte alimentaire), elle pose en fait, sur le plan théorique, plus de problèmes qu'elle n'en résout., Combris P., Nefussi Marc. Le concept d'agro-alimentaire : intérêt et limites. In: Économie rurale. N°160, 1984. pp. 22-27.

This PhD project aims at understanding better choice, liking and consumption of vegetables in 8- to -11-years children in natural situation of a school meal. In a first step, we focused on subjects (i.e. children) and studied their visual and perceptual knowledge of vegetables. We showed that carrots, tomatoes and lettuce were the three most familiar vegetables in children. Lexical knowledge of vegetables increases with age and is more important in rural children than urban ones. We did not observe a link between perceptual knowledge and children’s characteristics (i.e. age, gender, living environment or the possession of a vegetable garden at home). In a second step, we manipulated the shape and the duration of cooking for two objects (i.e. vegetables) selected at the end of the first step (i.e. a well-known and appreciated vegetable: carrots; a less known and less appreciated vegetable: broccoli). We studied the influence of these factors on children’s food behavior. Results showed that arrows are more frequently chosen, appreciated and consumed with a familiar shape and when less cooked. Visually, children preferred the broccoli presented in small florets rather than the big ones. The duration of cooking did not influence choices, liking and consumption of broccoli. The third step dealt with the influence of a situational variable: food labels. Firstly, we examined children’s preferences for several food labels, and secondly we studied the influence of these labels on children’s choice and consumption of two new recipes of carrots and broccoli. Adding a food label referring to the name of the vegetable was an effective mean to increase the probability that children would choose a new vegetable dish provided that no other more appreciated alternative was presented simultaneously. This research underlined the importance of children’s familiarity with the vegetable and its culinary form in their acceptance: children choose, appreciate and consume much more a familiar vegetable with a familiar culinary form. Also, the results showed that the food label participate to children food choice and underlined the importance of situational factors in food behavior., Ce travail de thèse porte sur le choix, l’appréciation et la consommation des légumes chez les enfants de 8 à 11 ans en situation naturelle de repas scolaire. Dans une première étape, nous nous sommes focalisés sur les sujets (i.e. enfants) en étudiant leurs connaissances lexicales et perceptives des légumes. Ainsi, nous avons mis en évidence que la carotte, la tomate et la salade sont les trois légumes les plus familiers chez l’enfant. Les connaissances lexicales des légumes évoluent avec l’âge et sont plus importantes chez les enfants ruraux que chez les urbains. Nous n’avons pas observé de lien entre les connaissances perceptives des enfants et leur âge, leur genre, leur lieu de vie ou encore leur possession d’un potager à la maison. Deux objets ont été sélectionnés à l’issue de la première étape : un légume très connu et apprécié -la carotte ; un légume moins connu et moins apprécié -le brocoli. Dans une seconde étape, nous avons étudié l’influence de la forme et du temps de cuisson de ces deux légumes sur le comportement alimentaire des enfants. Les résultats indiquent que la carotte est plus choisie, appréciée et consommée sous une forme familière et peu cuite. Les enfants préfèrent visuellement les fleurettes de brocoli de petite taille aux fleurettes de grosse taille. Le temps de cuisson n’a pas modifié l’appréciation et la consommation des brocolis. La troisième étape a porté sur une variable situationnelle : les intitulés de plats. Nous avons, d’une part, analysé les préférences des enfants pour des intitulés de plats, et d’autre part, étudié l’influence de deux types d’intitulés sur le choix et la consommation de nouvelles recettes de carotte et de brocoli. L’ajout d’un intitulé de plat précisant le nom du légume s’est révélé être un moyen efficace pour augmenter la probabilité de choix d’une nouvelle recette de légumes présentée conjointement à une recette familière. L’intitulé n’a pas eu d’influence, lorsque la nouvelle recette a été présentée conjointement à une alternative plus appréciée (i.e. le riz). Ces travaux soulignent l’importance de la familiarité de l’enfant avec le légume et avec sa forme culinaire : les enfants choisissent, apprécient et consomment plus un légume familier et sous une forme culinaire familière. De plus, les résultats ont montré que l’intitulé du plat participe au choix des enfants et soulignent l’importance des facteurs situationnels dans le comportement alimentaire.
