In modern societies it seems that the pleasures of taste often encourage the consumption of fatty, salty and sweet foods, whereas growing health awareness discourages consumption of the same foods. Numerous studies find that education and diet healthiness are highly correlated and one possible explanation is that consumers with a longer education are better at understanding and appreciating the health implication of their diet than are consumers with a short education. In this study we estimate a hedonic model of consumer’s valuation of food characteristics that allows nutrients to influence utility both through their perceived effects on health and their effects on the taste of food. The model is estimated using purchase data from a consumer panel with...

VOLUNTARY RESTRICTIONS ON TELEVISION ADVERTISING FOR CARBONATED SOFT DRINKS: THE IMPACT ON CONSUMER DEMAND

Berning, Joshua P..

The health implications and costs associated with increasing levels of obesity are a widespread global issue. In the United States, there is a growing interest in identifying methods to reduce obesity levels. Particular focus has been given to advertisements for unhealthy foods, especially advertisements directed at young children as a number of studies conclude that advertising influences the perceptions, requests and short-term consumption behavior of young children. Recently, several of the largest global food producers began voluntary selfregulation of their advertisements to children under the age of 12. The group of participants includes the two largest carbonated soft drink (CSD) manufacturers. We estimate the demand for CSDs in the US over 15...

For over the last thirty years the multinomial logit model has been the standard in choice modeling. Development in econometrics and computational algorithms has led to the increasing tendency to opt for more flexible models able to depict more realistically choice behavior. This study compares three discrete choice models, the standard multinomial logit, the error components logit, and the random parameters logit. Data were obtained from two choice experiments conducted to investigate consumers’ preferences for fresh pears receiving several postharvest treatments. Model comparisons consisted of in-sample and holdout sample evaluations. Results show that product characteristics hence, datasets, influence model performance. We also found that the...

We propose a detailed analysis of heterogeneity in households’ responses to water conservation programs (price increase, voluntary and mandatory conservation) during periods of water shortage. Using a unique dataset covering water consumption of all residential users in Los Angeles (California) during the drought (1988-1992), we show that households generally were responsive to the conservation measures but that the magnitude of households’ responses varies depending on the instrument and on households’ characteristics, in particular the size of their lot. Price elasticity is estimated between –0.29 and –0.47 in the high season (June-October), and between 0 and –0.19 in the low season (November-May). Results suggest that the voluntary conservation program...

We report results of an analysis of the attribution of relative responsibility across the stages of the food chain for ensuring food safety. Specifically, we identify perceptions of the share of the overall responsibility that each stage in the food chain has to ensure that the meat people cook and eat at home does not cause them to become ill. Results are reported for two groups of stakeholders: consumers and farmers, and for two types of meat: chicken and beef. The stakeholders’ opinions regarding the relative degrees of responsibility of the sequential food chain stages (feed supplier, farmer, livestock transportation, abattoir,… consumer) are elicited via surveys using the Maximum Difference technique (best-worst scaling). The data are analyzed using...

Los debates académicos y de políticas acerca de la actividad microempresarial se centran frecuentemente en las restricciones crediticias, asumiendo que los negocios se manejan de manera óptima dadas esas y otras restricciones. Los microempresarios, sin embargo, raramente tienen capacitación formal en gestión empresarial. Por su parte, un número creciente de instituciones de microfinanzas (IMF), en el Perú y el mundo, procura construir el capital humano de estos microempresarios para mejorar sus niveles de vida, contribuyendo a su misión de reducir la pobreza. Con ayuda de un diseño experimental, en este estudio medimos el impacto marginal de agregar un componente de capacitación en gestión empresarial a un programa de servicios financieros que atiende a...

The proper design of price interventions requires consideration of equity and efficiency effects. In this paper, budget survey data from 29,000 Indonesian households are used to estimate a demand system for five energy sources, which is identified by the spatial variation in unit values (expenditures divided by quantities). We correct for the various quality and measurement error biases that result when unit values are used as proxies for market prices. The price elasticities are combined with tax and subsidy rates to calculate the marginal social cost of price changes for each item. The results suggest that even at high levels of inequality aversion there is a strong case for reducing the large subsidies on gasoline and kerosene, supporting the reforms...

Data from U.S. households for year 2008 were used in examining market competitiveness of soymilk using tobit procedure. Unconditional own- and cross-price elasticities are larger than their conditional counterparts. Income, age, employment status, education level, race, ethnicity, region and presence of children are significant drivers affecting the demand for soymilk.

Impacts of Sample Size and Quality-Adjusted Imputed Prices on Own-Price Elasticities Estimated Using Cross-Sectional Data

Why Is the Obesity Rate So Low in Japan and High in the U.S.? Some Possible Economic Explanations

Stockton, Matthew C..

Cross-sectional data sets containing expenditure and quantity information are typically used to calculate quality-adjusted imputed prices. Do sample size and quality adjustment of price statistically alter estimates for own-price elasticities? This paper employs a data set pertaining to three food categories-pork, cheese, and food away from home-with four sample sizes for each food category. Twelve sample sizes were used for both adjusted and unadjusted prices to derive elasticities. No statistical differences were found between own-price elasticities among sample sizes. However, elasticities that were based on adjusted price imputations were significantly different from those that were based on unadjusted prices.

More than one billion adults are overweight worldwide, and more than 300 million of them clinically obese, raising the risk of many serious diseases. Only 3.6 percent of Japanese have a body mass index (BMI) over 30, which is the international standard for obesity, whereas 32.0 percent of Americans do. A total of 66.5 percent of Americans have a BMI over 25, making them overweight, but only 24.7 percent of Japanese. This paper examines the reasons Japan has one of the lowest rates of obesity in the world and the United States one of the highest, giving particular attention to underlying economic factors that might be influenced by policy changes. The average person in Japan consumes over 200 fewer calories per day than the average American. Food...

Taste Changes and Demographic in Spanish Seafood Consumption

Millan, Joaquin A.; Aldaz, Natalia.

This study analyses seafood consumption at home in Spain using three different cross-sectional survey data-sets for 1980, 1990 and 1998. Households are analysed in eleven different types, according to size and composition. Price indices for seafood and meats are calculated for each household type. Discrete participation and continuous consumption decisions are studied. Socio-economic variables sometimes play an important role but not with a regular pattern. Economic fundamentals follow a common pattern for all household types. Seafood demand is inelastic in 1980 and very elastic and meat complement in 1990 and 1998. Expenditure elasticity does not decrease between 1980 and 1998.

Using a series of hurdle choice models, this study considers both nay-saying and yeah-saying to alternatives offered in a conjoint experiment. These behaviors are characterized by respondents persistently choosing the no-choice alternative or choosing at least one of the non-empty options offered in a survey. Results show that jointly consider nay-saying and yeah-saying in a two-hurdle model drastically improves model fit; welfare implications based on hurdle models are also different from those based on models without hurdle specification.

Building on the results of an initial analysis of risk ranking data collected from a representative group of some 850 Canadian respondents in early 2003, this study assesses a similar set of risk ranking questions applied to a somewhat larger representative group of some 1500 Canadians in late 2005. We also compare the 2003 and 2005 risk rankings. In both surveys, risk rankings for eight food safety issues (bacteria contamination, pesticide residuals, use of hormones in food production, use of antibiotics in food production, BSE (mad cow disease), food additives, use of genetic modification/engineering in food production, fat and cholesterol in food) and six environmental safety issues (water pollution by chemical run-offs from agriculture, soil...

This paper proposes the use of multi-unit auctions in studying consumers’ willingness to pay (WTP) for food products in a multi-unit shopping scenario. We show how this method can overcome the limitations of single-unit experimental auctions in obtaining useful information related to WTP for not just the first unit but also subsequent units of a product, the demand curve, consumer surplus, the determinants of consumers’ WTP for each auctioned unit, and the effect of potential price discount strategies.

The Impact of Labeling Practices on Perceived Quality of GM Food Products: A Revealed Preferences Approach

Scatasta, Sara; Wesseler, Justus; Hobbs, Jill E..

This article contributes to the ongoing discussion about the impact of different labeling practices on the quality of genetically modified (GM) food products as perceived by the consumer. Thus far, many studies have adopted a stated preferences approach, finding that consumers have different willingness to pay for GM and non-GM products. This article offers an empirically tractable theoretical model that can be used easily to investigate the impact of GM labeling practices on the perceived quality of GM food products, making use of market data.
