The study focuses on various types of food safety risks: biological (zoonoses), chemical (chemical treatment of the meat) and technological (use of genetically modified feed). The emphasis was on how the perceived risks affect the purchase intentions in the case of broiler meat. In the case of each risk products the attitude-level variables had importance in explaining the buying intentions. The heterogeneity of the respondents regarding the purchase intentions of risk products was analysed by latent class logistic regression that included all three risk products. About 60% of the respondents belonged to the group of risk avoiders in which the purchase intention of risk food was significantly lower than in the second group of risk neutrals in which 64% of...

We designed a commitment savings product for a Philippine bank and implemented it using a randomized control methodology. The savings product was intended for individuals who want to commit now to restrict access to their savings, and who were sophisticated enough to engage in such a mechanism. We conducted a baseline survey on 1777 existing or former clients of a bank. One month later, we offered the commitment product to a randomly chosen subset of 710 clients; 202 (28.4 percent) accepted the offer and opened the account. In the baseline survey, we asked hypothetical time discounting questions. Women who exhibited a lower discount rate for future relative to current tradeoffs, and hence potentially have a preference for commitment, were indeed...

A Comparative Analysis of US and Canadian Consumers' Perceptions Towards BSE Testing and the use of GM Organisms in Beef Production: Evidence from a Choice Experiment

Gibson, John.

Rapid urbanization is a major cause of structural change in food demand. In West Africa, urbanization is associated with a switch from coarse grains to rice and wheat, in Melanesia the switch is from root crops to rice and wheat, while in much of Asia the switch is away from cereals (and within cereals to wheat). Although reasons why urban diets differ from traditional rural diets are well known, the rate at which recent arrivals from the countryside switch their diet has not been estimated. Evidence on the speed of this dietary change can help to show whether studies of urban food demand need to control for cohort effects and may also help producers forecast the size of their future urban markets. This paper uses cross-sectional household survey data from...

One source of phosphorous pollution in areas of high chicken production is runoff from fields using fertilizer from these operations. A potential solution is to feed chicken high available phosphorus (HAP) corn, reducing phosphorus in manure. This study examined consumer purchase likelihood of chickens fed HAP, created traditionally or through genetic modification, and other genetically modified (GM) corn including Bt and Roundup-ready. Survey results from the Delmarva Peninsula found considerable interest in non-GM HAP corn, although GM HAP corn was not typically viewed as more acceptable than other GM varieties. Overall, the marketplace appears open to products geared toward environmental benefits.

Economic techniques to estimate the demand for sustainable products: a case study for fair trade and organic coffee in the United Kingdom

Galarraga, Ibon; Markandya, Anil.

The hedonic approach is used in this paper to estimate how much is paid for the fair trade/organic characteristic of the coffee in the British market. This information is later combined with the Quantity Based Demand System (QBDS) model -developed by the authors- and the Almost Ideal Demand System (AIDS) (Deaton and Muellbauer, 1980) to completely determine the demand function for different coffees. The QBDS model is easier to handle and less data demanding than the AIDS model in this study. Resumen El presente artículo se basa en la utilización del método hedónico para la estimación de la cantidad que se paga por la característica de "Orgánico/Comercio Justo" del café en el mercado británico. La información obtenida se combina después con el modelo...

Expert opinion and cuisine reputation in the market for restaurant meals

Fogarty, James Joseph.

As food is an experience good, the market for restaurant meals is a market where the cost of acquiring information regarding quality is relatively high. In such markets consumers often turn to reputation measures to guide purchase decisions. As Australia does not have a longstanding cuisine style of its own, and given Australia has been open to substantial immigration inflows since federation, it represents an especially appropriate market to study regarding the impact of individual restaurant reputation and collective cuisine reputation on meal prices. The following study uses the hedonic price approach to investigate the implicit price of individual reputation indicators, cuisine type reputation indicators, and other objective indicators in the market...

Flat user fees in payment for environmental services (PES) schemes promote administrative ease, and are sometimes perceived as egalitarian. However, when environmental service (ES) buyers are heterogeneous in their income and water consumption levels, this may not be optimal, as total payments become too low and services are under-supplied. This paper identifies ES buyer preferences and estimates their willingness to pay (WTP) differentiated fees in an ongoing PES initiative in an Andean watershed in Colombia. Small, flat user payments have recently been introduced to implement incipient watershed protection upstream. Environmental service users fall into two highly heterogeneous categories: smallholder peasants and owners of recreational houses. We...

Household at-home consumption of different types and cuts of meat and fish products is investigated by estimating a large censored demand system with a two-step procedure using ACNielsen's Homescan data. We find different price and expenditure elasticities between low-income and high-income households. High income households are less responsive to price changes, and the substitution patterns also differ between the low- and high-income households. Whereas the uncompensated elasticities suggest a mixture of gross substitutes and complements among the products for both low- and high-income households, the compensated elasticities suggest net substitution is the obvious pattern for the low-income households.

Consumer acceptance and willingness to pay for three nonconventional attributes associated with six processed blueberry products was examined through an in-store conjoint experiment survey. Both credence and experience attributes were considered, including whether the products were produced locally, and whether they were organic or sugar-free. The results indicate heterogeneity in consumer preference and willingness to pay for different attributes across product categories. Local products and organic formulations generally received positive willingness to pay across all products. This information has implications for blueberry growers and retailers who are trying to create and position value-added products for maximum revenue.

“Pick the Tick” The Impact of Health Endorsements on Consumers’ Food Choices

Mueller, Simone C.; Umberger, Wendy J..

To determine the efficiency of health-related endorsements in influencing consumer choice we report findings from two separate, unique discrete choice experiments (DCEs) involving fresh packaged beef steaks and seafood. In addition to quality and production-related attributes, the beef and seafood products also displayed a health endorsement: the Australian National Heart Foundation “Pick the Tick” certification. Another, more recently introduced health claim, “2 Serves a Week” was also included in the seafood experiment. Consumer awareness of the “Pick the Tick” certification was higher than any other extrinsic claim considered in the experiments. Furthermore, in both experiments, “Pick the Tick” had the highest impact and value relative to other...

In this study we modeled demand interrelationships of at-home nonalcoholic beverage consumption in the United States using a unique data set developed using Nielsen HomeScan panel data of household purchases of nonalcoholic beverages over the period January 1998 through December 2003. We used 72 monthly observations of expenditure shares, real prices and real per capita expenditures of 10 unique categories of nonalcoholic beverages in a full-blown AIDS model with an adjustment for seasonal (quarterly) variability in data. Compared to similar studies done in the past, our study used a rich delineation of nonalcoholic beverage categories, and in particular introduced isotonics for the first time. Furthermore, our study provided more information about...

This study analyses whether Russian households differ in their choice of food quality when they differ in their number of overweight and obese members. Using survey data from the Russia Longitudinal Monitoring Survey (RLMS) for the years 1995-2005, households are classified into three weight groups. Quality elasticities of expenditures are estimated by a fixed-effects panel model regressing unit values of several food groups on expenditures and a set of household characteristics. Coefficients for each weight group are received by including interaction terms of expenditures and weight group dummies. A set of Wald tests is applied to test for slope heterogeneity across weight groups. Descriptive statistics reveal that obese households actually purchase...

Ascertaining the Impact of the 2000 USDA Dietary Guidelines for Americans on the Intake of Calories, Caffeine, Calcium, and Vitamin C from At-Home Consumption of Nonalcoholic Beverages

Hu, Wuyang.

In this paper, Chinese consumers' preferences and their willingness to pay (WTP) for non-genetically modified (GM) vegetable oil were elicited by a payment card approach. In addition to the conventional model, spike models, which were originally developed to evaluate public goods, were adopted in this paper. These spike models recognize the possibility of zero WTP and provide opportunities to analyze two correlated decision stages: whether to pay a premium for non-GM oil and how much the premium is. Results show that consumers behaved consistently in the two decision stages and there is a premium associated with non-GM oil.

Obesity is one of the most pressing and widely emphasized health problems in America today. Beverage choices made by households have impacts on determining the intake of calories, calcium, caffeine, and vitamin C. Using data from the Nielsen Homescan Panel over the period 1998–2003, and a two-way random-effects Fuller-Battese error components procedure, we estimate econometric models to examine economic and demographic factors affecting per-capita daily intake of calories, calcium, caffeine, and vitamin C derived from the consumption of nonalcoholic beverages. Our study demonstrates the effectiveness of the USDA 2000 Dietary Guidelines in reducing caloric and nutrient intake associated with nonalcoholic beverages.

USING BEST WORST SCALING TO INVESTIGATE PERCEPTIONS OF CONTROL AND CONCERN OVER FOOD AND NON-FOOD RISKS

Erdem, Seda; Rigby, Dan.

This research locates a series of risks or hazards within a framework characterized by the level of control respondents believe they have over the risks, and the level of worry the risks prompt. It does this for a set of both food and non-food risks. The means by which this is done is novel and differs from past risk perception analyses in that it asks people directly regarding their relative assessments of the levels of control and worry regarding the risks presented. The cognitive burden associated with people ranking and scaling items in large sets is notoriously heavy and so this study uses an elicitation method designed to make the process intuitive and cognitively manageable for respondents. The substantive analysis of the risk perceptions has 4 main...

Banzhaf, H. Spencer.

This paper illustrates how public goods may be incorporated into a cost-of-living index. When public goods are weak complements to a market good, quality-adjusted prices for the market good capture all the welfare information required. They are also consistent with a Laspeyres index that maintains the bound on a true cost-of-living index. The paper recovers this information from a discrete-choice model, using a simulation routine to solve for the appropriate price adjustments. These concepts are applied to the case of housing, education, crime, and air quality in Los Angeles for 1989 to 1994. Over a period of time when they are improving, incorporating pubic goods into the index lowers the estimated change in the cost of living by 0.5 to 2.6 percentage...

Demand relationships between salmon and a number of wild-caught whitefish and shellfish species using both single equation models and linearised AIDS system framework. The system is well represented although autocorrelation were found in both approaches but this is less of a problem in the systems approach. A cautious interpretation of the results indicated that salmon had a long-run market relationship with the whitefish species of cod, monkfish, saithe, whiting and plaice and with the shellfish species of mussels, nephrops, scallops and shrimp. These groups contain the main seafood species consumed within the United Kingdom, and therefore should include most potential substitutes for salmon.

Consumers use of quality characteristics to make milk purchase decisions reveal opportunities to create successful marketing strategies. Such a strategy could concern food quality. In this case, three core areas influence consumers quality perception: the perception process, the physical product itself and the communication about it (Grunert et al., 1996). Beyond this background, this article analyzes the impact of certain quality characteristics and socio-demographics on consumption patterns regarding whole fat milk, skim milk and organic milk. These milks were chosen because of the increasing awareness of different fat contents in the meaning of lower fat contents being healthier and the increasing importance of the organic food market.

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...
