What Affects Consumption Patterns of Organic and Conventional Products? AgEcon
Grebitus, Carola; Yue, Chengyan; Bruhn, Maike; Jensen, Helen H..
Consumers show an increased interest in organic food today and a willingness to pay premium for organic products. In addition to price, changing attitudes and beliefs about food quality affect food choice. This article analyses the impact of attitudes, quality characteristics and socio-demographics on consumption of organic and conventional pork, potatoes and milk. The concept of ‘perceived quality’ provides the theoretical background. The data come from a consumer survey conducted in Germany in 2004 (n=260). An ordered logit model was used for analysing the data. We observe clear differences in consumers’ use of certain quality characteristics as they perceive and evaluate conventional and organic fresh foods.

CONSUMER INTENTIONS OF BUYING POULTRY MEAT UNDER PERCEIVED BIOLOGICAL, CHEMICAL OR TECHNOLOGICAL RISK IN FINLAND AgEcon
Heikkila, Jaakko; Pouta, Eija; Forsman-Hugg, Sari; Makela, Johanna.
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...

What is it Consumers really want, and how can their preferences be influenced? The Case of fat in Milk AgEcon
Andersen, Laura M.; Smed, Sinne.
In this paper we investigate preferences for fat in milk through a structural characteristics model. The data includes information about daily purchases and social and demographic characteristics of more than 1,100 households. We find that consumers who prefer milk with a high fat content do not react to information about health effects, but can be influenced by prices, while consumers who prefer milk with a low share of fat are influenced by information, but are less price sensitive. Therefore, when attempting to decrease consumption of fat from milk, prices are more efficient than information.

Heterogeneous Responses to Water Conservation Programs: The Case of Residential Users in Los Angeles AgEcon
Hanemann, W. Michael; Nauges, Celine.
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...

An Empirical Investigation of Interproduct Relationships Between Domestic and Imported Seafood in the U.S. AgEcon
Lee, Young-Jae; Kennedy, P. Lynn.
This study seeks to identify interproduct relationships between domestic catfish and a representative selection of imported seafood. In doing so, this study uses multivariate cointegration and structural analyses. Multivariate cointegration analysis suggests that six imported seafood product groupings form a common market with domestic catfish. Structural analysis reveals that 1) domestic and imported catfish are net and gross quantity substitutes; 2) domestic catfish and imported seafood are normal goods; 3) six imported seafood products are identified as gross quantity substitutes for domestic catfish; and 4) according to the derived Allais coefficients, interaction intensities of imported seafood for domestic catfish (from greatest to least) are as...

THE INFLUENCES OF AVIAN INFLUENZA, BSE, AND H1N1 INFLUENZA ON ATTITUDINAL CHANGES IN MEAT SAFETY ISSUES AgEcon
Hsu, Jane Lu; Liu, Kang Ernest; Lee, Hwang-Jaw; Huang, Min-Hsin; Hung, Kelsey Jing-Ru.
Consumption patterns for chicken and eggs have changed since the outbreak of the H5N1 avian influenza (AI) throughout the world, but its potential impact on demand has not been thoroughly unveiled. Our study examines some important factors influencing behavioral changes and estimates their marginal effects by employing the censored regression model to survey data in Taiwan. Results showed that risk perceptions, overall knowledge and some socio-demographic characteristics were profound in determining changes in consumption of chicken and eggs. Public health education programs informing consumers about the AI threat may reduce their negative perceptions; therefore, consumption of chicken and eggs would not be decreased significantly enough to damage related...

WHO IS MOST RESPONSIBLE FOR ENSURING THE MEAT WE EAT IS SAFE? AgEcon
Erdem, Seda; Rigby, Dan; Wossink, Ada.
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...

Consumer Willingness to Pay for Fair Trade Coffee: A Chinese Case Study AgEcon
Yang, Shang-Ho; Hu, Wuyang; Mupandawana, Malvern; Liu, Yun.
Coffee consumption in China has seen a significant rise in recent years. This study seeks to explore the determinants of coffee consumption in China with a specific focus on fair trade coffee. In a survey of 564 respondents in Wuhan City, consumers’ willingness to pay (WTP)for fair trade labeled coffee was measured. This study uses an interval regression to investigate individual demographic and consumption characteristic impacts on WTP. Results show that on average, consumers were willing to pay 22% more for a medium cup of fair trade coffee compared with traditional coffee. In addition, other variables that indicated a higher WTP included female consumers, consumers who made their own coffee, and consumers who planned to consume more coffee in the...

Estimation of a Censored AIDS Model: A Simulated Amemiya-Tobin Approach AgEcon
Dong, Diansheng; Kaiser, Harry M..
Kuhn-Tucker approach and its dual have been proposed to the demand system estimation when there are non-negativity bindings. However, empirical researchers have been struggling two decades in applying this method into practice due to: (1) the difficulty in derivation of a coherent econometric model, and (2) the cumbersome evaluation of high order probability integrals needed in parameter estimation. In this paper, we avoid the above two issues by using the Amemiya-Tobin demand system approach and the simulation procedure to evaluate the probability integrals. An AIDS model is estimated and the elasticities are obtained that are impossible to achieve when using Kuhn-Tucker approach. The model is applied to an analysis of Canadian household food demand.

A non-compensatory choice modeling analysis of Japanese consumers’ preferences for beef: A choice experiment approach AgEcon
Aizaki, Hideo; Sawada, Manabu; Sato, Kazuo; Kikkawa, Toshiko.
The purpose of this paper is to examine, using choice experiments, the Japanese consumers’ valuation of domestic Wagyu beef, domestic dairy beef, Australian beef, and US beef when considering their bovine spongiform encephalopathy (BSE) test status. Some Japanese consumers give high priority to food safety while purchasing beef; this is expected to cause a non-compensatory valuation of food safety. As compared to the results derived from a compensatory utility model, a random parameters logit (RPL) with a non-compensatory utility model provides estimation results that are fitter for the respondents’ decision-making rules and also provides more valid willingness to pay (WTP) for each type of beef. The results suggest that the RPL with the non-compensatory...

The effects of food habits and socioeconomic status on overweight. Differences between the native Dutch and immigrants in the Netherlands AgEcon
Cornelisse-Vermaat, Judith R.; Maassen van den Brink, Henriette.
Overweight is a worldwide growing epidemic. The Netherlands is among the countries with the highest prevalence for overweight, together with the USA, UK, and Germany. This paper investigates differences in overweight between native Dutch and three immigrant groups in the Netherlands, and the effects of food habits and socioeconomic status on overweight. The results show that all immigrant groups have a higher prevalence for overweight than the Dutch, apart from Moroccans. Males are overweight more frequently than females. Takeaway food, eating out, and fresh vegetables decrease BMI, while convenience food, ready-to-eat meals, and delivery food (in some cases) increase BMI. In all groups, BMI increases with age. For Surinamese/Antilleans and Turks BMI...

Retail Competition in the Milk Market in a U.S. Midwestern City AgEcon
Hovhannisyan, Vardges; Gould, Brian W..
The main goal of this manuscript is to explore the retailer conduct in the milk market in a U.S. Midwestern city, based upon a structural estimation of consumer milk demand and retailer optimality conditions. To model milk demand we rely upon the Almost Ideal Demand System, while allowing the retailer optimality conditions to cover a range of competitive scenarios from perfect competition to horizontal cartel. We employ a conjectural variation approach in the spirit of Newly Empirical Industrial Organization to study the competitive environment on the retail landscape. We find that the retail market in question is far from being competitive, with the two major retailers being engaged in an oligopolistic competition. Furthermore, the private label milk...

Consumer Willingness to Pay for Breads Marketed as "Low-Carbohydrate" AgEcon
Wachenheim, Cheryl J.; Nganje, William E.; Kaitibie, Simeon; Johnston, Gretchen.
Bread producers are taking advantage of healthy feeding habits by developing new "low carbohydrate" products to entice customers. These low carbohydrate breads are generally more expensive than conventional types. This study tests the hypothesis that consumers are willing to pay higher premium for "low carbohydrate" breads at various locations and markets. We use retail data in a hedonic pricing framework to estimate the premium paid for the "low carbohydrate" attribute of bread. Results show that the implicit price of the "low carbohydrate" attribute of bread ranges from about 0.06¢ to 1.1¢ per gram, reflecting the amount consumers are willing to pay above the price of conventional bread.

DEMOGRAPHIC VARIABILITY IN U.S. CONSUMER RESPONSIVENESS TO CARBONATED SOFT-DRINK MARKETING PRACTICES AgEcon
Rhodes, Charles.
Using three years of Nielson Homescan and advertising data from 16 major metropolitan areas across the U.S. to construct a panel data set that follows weekly consumer purchasing behavior, this paper investigates the impact of marketing activities on a representative cross-section of U.S. consumers. Because many consumers do not participate in the market week-in and week-out, I apply Heckman’s econometric selection model to recover the impact of pricing, advertising, and promotion on a wide range of consumer segments. Reduced-form estimates of consumer responsiveness to these marketing activities reveal different effects across consumer segments, which have numerous implications for marketing policy.

DEMAND FOR BREAKFAST CEREALS: WHOLE GRAINS GUIDANCE AND FOOD CHOICE AgEcon
Ishdorj, Ariun; Jensen, Helen H..
When using household-level data to examine consumer demand it is common to find that consumers purchase only a subset of the available goods, setting the demand for the remaining goods to zero. Ignoring such censoring of the dependent variables can lead to estimators with poor statistical properties and estimates that lead to poor policy decisions. In this paper we investigate household demand for four types of breakfast cereals, such as whole grain ready-to-eat, non-whole grain ready-to-eat, whole grain hot and non-whole grain hot cereals, using a censored Al- most Ideal Demand System (AIDS) and estimate the parameters of the model via Bayesian methods. Using household level scanner data (ACNielsen Homescan) we find that demand for all types of breakfast...

Consumer Interest in Environmentally Beneficial Chicken Feeds: Comparing High Available Phosphorus Corn and Other Varieties AgEcon
Pesek, John D., Jr.; Bernard, John C.; Gupta, Meeta.
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.

Monte Carlo Benchmarks for Discrete Response Valuation Methods AgEcon
Huang, Ju-Chin; Smith, V. Kerry.
This paper argues that the widespread belief that discrete contingent valuation (CV) questions yield substantially larger estimates of the mean (and the median) willingness to pay (WTP) for nonmarket environmental resources in comparison to estimates from open-ended CV questions is unfounded. A set of Monte Carlo experiments estimate the factors influencing the performance of WTP estimates based on discrete response models. Most of the error in the WTP estimates arises from the specification errors that are common in most of the empirical models used in the literature. These experiments suggest models based on choices where WTP is dominated by non use (or passive use) values are likely to have smaller errors than where large use values influence these...
