Health Benefits and Uncertainty: An Experimental Analysis of the Effects of Risk Presentation on Auction Bids for a Healthful Product AgEcon
Shaw, W. Douglass; Nayga, Rodolfo M., Jr.; Silva, Andres.
Experimental subjects receive a different presentation of a food product's potential health risk reductions if people habitually eat it, and then asked to bid for the product. Results suggest that the bids vary across the groups that receive differing risk information.

THE EFFECT OF FOOD LABEL USE ON NUTRIENT INTAKES: AN ENDOGENOUS SWITCHING REGRESSION ANALYSIS AgEcon
Kim, Sung-Yong; Nayga, Rodolfo M., Jr.; Capps, Oral, Jr..
This study examines the impact of consumers'’ use of food labels on selected nutrient intakes of Americans. Endogenous switching regression techniques are employed to control for heterogeneity in the label use decision. When the nutrient intakes of label users and the expected nutrient intakes of label users in the absence of labels are compared, food label use decreases individuals'’ average daily intakes of calories from total fat and saturated fat, cholesterol, and sodium by 6.90%, 2.10%, 67.60 milligrams, and 29.58 milligrams, respectively. In addition, consumer nutrition label use increases average daily fiber intake by 7.51 grains.

Socio-economic Profiles of Nutrition Label Users AgEcon
Zhang, Ge; You, Wen; Nayga, Rodolfo M., Jr..
This paper aims to explore the socio-economic profiles of the nutrition label users and focuses on seven key nutrients: calories, calories from fat, total fat, trans fat, saturated fat, cholesterol, and sodium. The data are from National Health and Nutrition Examination Survey (NHANES) 2005-2006 and Continuing Survey of Food Intakes by Individuals (CSFII) 1994-96. Similar conclusions are drawn from both data sets: those consumers who are older, better educated, higher income, female, and have higher nutrition knowledge will have higher probability to use nutrition labels; those consumers who are in larger size families and being either Hispanic or black have lower probability of using nutrition labels.

Food involvement and food purchasing behaviour AgEcon
Drichoutis, Andreas C.; Lazaridis, Panagiotis; Nayga, Rodolfo M., Jr..
This paper investigates the factors affecting product class involvement for food. Factors affecting specific aspects of involvement are also explored. The aim is to determine the factors that affect involvement with food and sketch the profile of consumers more likely to be involved or not involved with food. Building on the literature a conceptual model is developed and empirically tested using survey data collected from supermarkets in Athens. Data were analyzed using probit and ordered probit analysis and marginal effects were calculated which show how much the level of involvement or importance is affected when a variable is changed. Results show that younger consumers, those with higher education and income that engage in nutritional label use...

The Effect of Risk Presentation on Product Valuation: An Experimental Analysis AgEcon
Nayga, Rodolfo M., Jr.; Shaw, W. Douglass; Silva, Andres.
We examine how people might evaluate a product with novel attribute, given various kinds of risk information. Using a product with healthful benefits, we assess subjects'’ willingness to pay given various kinds of health risk information conveying reduced health risks, life tradeoffs, and ambiguity. Four treatments in separate non-hypothetical experimental auctions are used to elicit willingness to pay values. Results suggest that willingness to pay vary across the groups that receive differing risk information. Specifically, willingness to pay was higher for the group that was given clear risk information and questions related to life tradeoffs than for the group given ambiguous risk information. Willingness to pay was lowest for the group that was...

CONSUMER CHARACTERISTICS ASSOCIATED WITH LOW FAT, LOW CHOLESTEROL FOODS AgEcon
Nayga, Rodolfo M., Jr..
This study identifies several characteristics and factors of individuals who are more likely to try low-fat, low-cholesterol foods. The analysis was performed using logit analysis. The results imply that the following individuals are more likely to try low-fat, low-cholesterol foods: those with high incomes, whites compared to blacks, females, those with smaller households, those with high body mass index, those who have a better perception of their own health, those who are aware of the link between diet and disease, nonsmokers, and those who do not agree that people are born fat or thin and that there is nothing one can do about it.

THE SINGLE INDEX MARKET MODEL IN AGRICULTURE AgEcon
Gempesaw, Conrado M., II; Tambe, A.M.; Nayga, Rodolfo M., Jr.; Toensmeyer, Ulrich C..
This study illustrates the differences in empirical results due to data measurements and estimating procedures when applying the single index market model in agriculture. Gross and net return betas along with systematic and unsystematic risk proportions are estimated and found to be different. The stochastic coefficients model is used to show the difference in beta-risk estimates compared with the traditional fixed coefficients OLS procedure. A third estimating technique, weighted least squares/Prais Winsten method, is also proposed.

BUSINESS CLIMATE OF FOOD FIRMS: A COMPARATIVE ANALYSIS OF PROBLEMS FACED BY FOOD MANUFACTURERS, WHOLESALERS, RETAILERS AND SERVICE INSTITUTIONS IN NEW JERSEY AgEcon
Adelaja, Adesoji O.; Nayga, Rodolfo M., Jr.; Tank, Karen Rose; Schilling, Brian J..
This paper presents the problems facing food firms using information from focus groups of industry executives from New Jersey. The leading problems for food manufacturers are related to regulation, taxation, economic development, and high business costs. For food wholesalers the leading problems are transportation, regulation, labor quality, training and education, and public relations. Food retailers cite litigation and liability, high business costs, regulation, and insurance costs as leading problems. For food service firms, regulation, licensing and permits, labor quality and costs, and high business costs are the most pressing problems. Policy recommendations for improving the business climate are provided.

Initial Endowment Effects in Multi-Unit Vickrey Auctions AgEcon
Akaichi, Faiçal; Nayga, Rodolfo M., Jr.; Gil, Jose Maria.
We report the result of experiments designed to assess the effect of initial endowments on willingness to pay values elicited from multi-unit Vickrey auctions. Comparing bids from an “endow and upgrade” approach with the “full bidding” approach, we find that the direction of the endowment effect generally depends on the number of endowed units of the conventional product that subjects are willing to give up in exchange for units of the upgraded product. The endowment effect is “reverse” when the number of units that participants are willing to give up is lower or equal to the number of remaining endowed units. However, we generally find an endowment effect when the number of units a participant is willing to give up is higher than the number of remaining...

Consumer Acceptance of Nutritionally Enhanced Genetically Modified Food: Relevance of Gene Transfer Technology AgEcon
Onyango, Benjamin M.; Nayga, Rodolfo M., Jr..
This study examines consumer's willingness to consume different types of a nutritionally enhanced food product (i.e., breakfast cereal with calcium, omega fatty acids, or anti-oxidants) derived from grains genetically modified using two types of technologies: plant-to-plant gene transfer technology and animal-to plant gene transfer technology. Findings indicate a majority of the respondents are willing or somewhat willing to consume the three types of nutritionally enhanced genetically modified breakfast cereal, but are less willing if the genetically modified product is derived from animal-to-plant gene transfer technology than from plant-to-plant gene transfer technology. However, the results of the ordered probit models suggest there are groups of...

FOOD NUTRITIONAL QUALITY: A PILOT STUDY ON CONSUMER AWARENESS AgEcon
Schmitz, John D.; Nayga, Rodolfo M., Jr..
Retail food demand studies are becoming increasingly concerned with the role of nutrition and health, yet consumer perceptions and attitudes are often ignored. The purpose of this pilot study is to determine consumer perceptions involving nutrition levels for selected foods. The influence of demographics and information about nutrition and health on perceptions toward meat items are determined. Results generally indicate that consumer perceptions toward fat and cholesterol levels in meats are based on the comparison of animal sources, not the comparison of individual cuts or preparation techniques. Recent efforts in the study of retail food demand have moved toward the role of nutrition and health. Several attempts have been made to measure the role that...

ANALYSIS OF ALCOHOL CONSUMPTION IN THE UNITED STATES: PROBABILITY AND LEVEL OF INTAKE AgEcon
Nayga, Rodolfo M., Jr.; Capps, Oral, Jr..
This article examines the impact of socio-demographic factors on individual consumption of alcohol in the United States using the Heckman procedure and logit analysis. Factors considered are urbanization, race, ethnicity, region, weight, height, sex, food stamp participation, employment status, diet status, day of consumption, household size, age, and income. All the variables, with the exception of ethnicity and food stamp participation, significantly influence the decision to consume alcohol. Results also indicate that urbanization, region, sex, food stamp participation, and household size significantly affect the level of alcohol consumption.

Italian Consumer Acceptance of Nutritionally Enhanced GM Food AgEcon
Canavari, Maurizio; Tisselli, Farid; Nayga, Rodolfo M., Jr.; Scarpa, Riccardo.
The aim of this article is to evaluate Italian consumers’ acceptance and willingness to purchase GM foods based on the type of benefit (input vs output trait) and product (plant based vs animal based). Two surveys were administered in two consecutive years (2004 and 2005) and the data used to test for possible changes in consumer acceptance. The results of a multinomial logit analysis suggest that on average consumer acceptance for plant-based GM food was higher in 2005. This study confirmed the key role of information strategies to consumers, with the most relevant results being the role distorted information play in raising the consumer’s level of fear and perceived risk. Respondents also place a higher level of confidence on scientists who are generally...

DETERMINANTS OF FARMER-TO-CONSUMER DIRECT MARKET VISITS BY TYPE OF FACILITY: A LOGIT ANALYSIS AgEcon
Govindasamy, Ramu; Nayga, Rodolfo M., Jr..
This study identifies several socioeconomic and demographic characteristics of individuals who visited farmer-to-consumer direct markets in New Jersey. The analysis was performed for each type of direct marketing facility: pick-your-own farms, roadside stands, farmers' markets, and direct farm markets. Logit analysis results indicate that various factors affect visitation to each type of facility. Factors examined include consumers' consumption and variety of fruits and vegetables, price expectation, purpose of buying, age, sex, education, race, income, urbanization, and presence of home garden.

RESEARCH REPORTS: THE ECONOMIC FEASIBILITY OF A NEW JERSEY FRESH TOMATO PACKING FACILITY: A STOCHASTIC SIMULATION APPROACH AgEcon
Peacock, Kristin M.; Nayga, Rodolfo M., Jr.; Brumfield, Robin G.; Bacon, J. Richard; Thatch, Daymon W..
This study evaluates the economic feasibility of establishing a packing house for the New Jersey Tomato Council Cooperative Association. Several scenarios were evaluated using a comprehensive firm-level, dynamic, stochastic, multiple-year, capital-budgeting computer model. Results indicate that the packing house would have difficulty sustaining itself if it packed tomatoes only during the three months a year that local tomatoes are produced. Economic performance of the packing house improved, however, when additional tomatoes were repacked from another supplier during the months that tomatoes are not produced in New Jersey.

Household Fast Food Expenditures and Children's Television Viewing: Can They Really Significantly Influence Children's Dietary Quality? AgEcon
You, Wen; Nayga, Rodolfo M., Jr..
Previous studies have found a strong relationship between food-away-from-home expenditures and television viewing, and children's diet. This study revisits this issue by examining the impact of household fast food expenditures and children's television viewing on children's dietary quality. Results indicate that both factors have statistically significant and negative effects. However, the elasticities of children's diet quality with respect to both factors are quite inelastic. Results also suggest that the effects of these two factors differ between children younger than 11 years old and children at least 11 years old. Relevant policy implications are discussed.

PEER-EFFECTS IN OBESITY AMONG PUBLIC SCHOOL CHILDREN: A GRADE-LEVEL ANALYSIS AgEcon
Asirvatham, Jebaraj; Nayga, Rodolfo M., Jr.; Thomsen, Michael R..
We examine the role of peer effects in childhood obesity outcomes by investigating whether obesity rates among the highest graders in a public school has an effect on obesity rates among younger grades. We use a panel dataset with obesity prevalence measured at the grade level. Our data are from Arkansas public schools. Results provide evidence that changes in the obesity prevalence at the highest grade are associated with changes in obesity prevalence at younger grades. The magnitude of the peer effect depends on the type of school, and we find statistically significant peer effects in both elementary and high schools but not in middle schools. These effects are also larger in high schools than in elementary schools. We use falsification tests to provide...
