Estimation of a hedonic price equation for Burgundy wine

Pierre Combris; Sébastien Lecocq; Michael Visser

A hedonic price equation and two jury grade equations are estimated for Burgundy wine. The approach is the same as in an earlier Bordeaux wine paper (Combris et al., 1997). The data come from an experimental study that is very similar to the study on Bordeaux wines. The results for the two wine-growing regions are compared and discussed.

Expected versus experienced quality: trade-off with price

Christine Lange; Sylvie Issanchou; Pierre Combris

This study was conducted in order to compare the behaviour of consumers who had to choose products under economic constraint in two conditions: when perceived quality was based on expectation generated by packaging images, versus when perceived quality was based on sensory experience in presence of packaging images. Randomly selected participants were endowed with a real budget and placed in five different price/budget situations. They stated their choice among six orange juices in each price/budget situation. This task was performed for the two different information conditions. Results demonstrate that participants who chose products without tasting made their choices more rapidly, chose a larger number of variants and their choices tended to be less influenced by liking scores, as compared to participants who chose products after tasting. The comparison between these two conditions permitted us to understand behaviour differences when consumers were in a total or restricted information situation.

World meat consumption patterns: An overview of the last fifty years (1961-2011).

Pierre Sans; Pierre Combris

Driven by economic development and urbanisation, protein consumption has surged worldwide over the last 50years, rising from 61g per person per day in 1961 to 80g per person per day in 2011 [Corrected]. 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.

Assessing the Effect of Information on the Reservation Price for Champagne: What are Consumers Actually Paying for?

Pierre Combris; Christine Lange; Sylvie Issanchou

Two series of Vickrey auctions have been performed to assess the effect of packaging information (bottle and label) on the reservation prices of ordinary consumers for five brut non-vintage Champagnes. As in other studies on wine tasting, packaging information is found to explain much more of the variation in willingness to pay than sensory information. Participants are unable, or unwilling, to put different values on the Champagnes after blind tasting, but significant differences in reservation prices appear when labels are disclosed. Detailed analysis of choices reveals a large heterogeneity in individual behaviors and valuations of the Champagnes included in this study. (JEL Classification: C91, D12)

Le poids des contraintes économiques dans les choix alimentaires

Pierre Combris

Resume L’evolution a long terme de la consommation met en evidence l’impact des facteurs economiques sur les choix alimentaires. En France, comme dans les autres pays industrialises, apres une phase de subsistance ou la ration calorique etait proche du minimum vital, le regime alimentaire a evolue d’abord quantitativement grâce a un accroissement de la consommation des aliments les moins chers, puis qualitativement, avec, en particulier, un accroissement de la part des produits d’origine animale, des graisses et du sucre. Cette transition nutritionnelle debouche maintenant sur une phase de stabilite de la structure des apports en macronutriments. La baisse des prix des aliments, et en particulier des aliments de base, a joue un role cle dans cette evolution. Ces changements ont eu de nombreux effets positifs, mais ils laissent subsister des inegalites nutritionnelles, dont le developpement de l’obesite et des maladies chroniques d’origine alimentaire sont les manifestations les plus visibles.

French Consumers’ Attitudes and Preferences toward Wild and Farmed Fish

Kyrre Rickertsen; Frode Alfnes; Pierre Combris; Géraldine Enderli; Sylvie Issanchou; Jason F. Shogren

ABSTRACT 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. JEL Codes: C91, D12, Q22.

Impact of information and in-home sensory exposure on liking and willingness to pay: The beginning of Fairtrade labeled coffee in France

Christine Lange; Pierre Combris; Sylvie Issanchou; Pascal Schlich

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 coffees and/or exposure to ethical information. In the 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 sessions 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.

Bootstrap généralisé d'un sondage

Patrice Bertail; Pierre Combris

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.

Product Information, Hedonic Evaluation, and Purchase Decision: an Experimental Study of Orange Juice

Pierre Combris; Christine Lange; Sylvie Issanchou

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)

Ambroise Martin; Michel Chauliac; Pierre Combris; Corinne Delamaire; Landy Razanamahefa; Louis-Georges Soler; Laure Souliac; Marianne Storogenko; Dominique Turck; Jean-Luc Volatier

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.
