A CHOICE-EXPERIMENT BASED ANALYSIS OF PROTECTION MOTIVATION THEORY: HEALTH RELATED BEHAVIOR OF CONSUMERS WITH CELIAC DISEASE AgEcon
Zhang, Jing; Steiner, Bodo E..
The underlying components of protection motivation theory (PMT; Rogers 1983) are explored through choice experiment-based analysis within a random utility framework, to account for some of the motivational, cognitive, and affective processes that likely affect celiacs’ propensity to use a novel health-risk reducing product. Those four groups of variables that are aimed to capture threat appraisal and coping appraisal processes as part of the standard PMT (Rogers 1975, 1983; Floyd et al. 2000) are found to contribute significantly to explaining the adaptive response of celiacs. Self-assessed vulnerability and perceived product efficacy form a most significant part of respondents’ threat appraisal process. Standard socio-demographic and lifestyle...

A double-hurdle model of Irish households' foodservice expenditure patterns AgEcon
Keelan, Conor D.; Henchion, Maeve M.; Newman, Carol F..
The aim of this paper is to analyse the various factors fuelling demand for Food- Away - From- Home (FAFH) in Ireland. The two largest components of this industry, the quick- service sector (fast food and takeaway) and the full- service sector (hotel and restaurant meals), are analysed using the most recently available Household Budget Survey data for Ireland. The results from a Box- Cox double hurdle model indicate that different variables affect expenditure in the different sectors in different ways. Income has a greater effect on full- service expenditure than on quick- service. Similarly households that are healthconscious indicate a greater preference for full- service meals while households with higher time values indicate a greater preference for...

A Flexible Multistage Demand System Based on Indirect Separability AgEcon
Moschini, GianCarlo.
The notion of indirect separability is exploited to derive a new multistage demand system. The model allows a consistent parameterization of demand relations at various budgeting stages and it fulfills the requirement of flexibility while satisfying separability globally. Two propositions are derived to characterize flexible and separable functional forms, which lead to the specification of a flexible and separable translog (FAST) demand system. The model is particularly attractive for modeling large complete demand systems, and is illustrated with an application to Canadian food demand.

A Latent-Variable Approach to Modelling Multiple and Resurgent Meat Scares in Italy AgEcon
Mazzocchi, Mario; Lobb, Alexandra E..
This paper aims to measure the time pattern of multiple and resurgent food scares and their direct and cross-product impacts on consumer response. The Almost Ideal Demand System (AIDS) is augmented by a flexible stochastic framework which has no need for additional explanatory variables such as a media index. Italian aggregate household data on meat demand is used to assess the time-varying impact of a resurgent BSE crisis (1996 and 2000) and the 1999 Dioxin crisis. The impact of the first BSE crisis on preferences seems to be reabsorbed after a few months. The second wave of the scare at the end of 2000 had a much stronger effect on preferences and the positive shift in chicken demand continued to persist after the onset of the crisis. Empirical results...

A meta-analysis of the response of calorie demand to income changes AgEcon
Ogundari, Kolawole; Abdulai, Awudu.
Over the past three decades, several studies have analyzed the response of calorie intake to income with varying and inconclusive results. This paper review these studies and employs meta-analysis to examine the potential bias in the calorie-income elasticity, as well as the impact of specific study attributes on these elasticities reported in the empirical literature. A total of 40 studies which yielded 99 estimated elasticities were considered. The results show the presence of publication (reporting) selection bias in the reported elasticities. Besides, the estimates revealed evidence of positive and significant empirical effect of income on calorie intake from all the studies that goes beyond publication bias. Study attributes such as ranking of the...

A MODEL OF HOUSEHOLD TYPE SPECIFIC FOOD DEMAND BEHAVIOUR IN HUNGARY AgEcon
Brosig, Stephan.
The paper describes a two stage model of Hungarian households'’ food demand. Demand for the food aggregate is represented by a Working-Leser type single equation model while demand for seven distinct food types is modelled in a complete demand system using the LA/AIDS functional form. Estimation is based on household budget survey data for 1996. Demand elasticities are estimated for average households as well as for specific groups defined by sociodemographic characteristics. Fruit and vegetables are found to be the food types with most elastic demand but in general, differences between elasticities for different products as well as between different sociodemographic groups are relatively small.

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...

A Non-Hypothetical and Incentive Compatible Method for Estimating Consumer Willingness-to-Pay for a Novel Functional Food: The Case of Pomegranates AgEcon
McAdams, Callie P.; Palma, Marco A.; Ishdorj, Ariun; Hall, Charles R..
A preference and valuation mechanism that compared results of an experimental auction and nonhypothetical preference rankings was developed and used to elicit preferences for pomegranate products from a representative sample of shoppers in Texas. Familiarity with pomegranate products increased willingness-to-pay (WTP) for pomegranates, as did tasting and providing additional information on the health benefits of the products. Ready-to-eat and juice products were preferred to whole fruit products. Subjects did not indicate an increased WTP for Texas varieties over California Wonderful pomegranate based on auction bids but indicated a preference for one Texas variety in the nonhypothetical ranking procedure; thus, the auction results and nonhypothetical...

Adult Obesity and Food Stores’ Density – Evidence from State-Level Panel Data AgEcon
Bonanno, Alessandro; Goetz, Stephan J..
The association between types of food access and rising adult obesity rates is increasingly recognized, as a complement to the effects of declining physical activity. Previous studies have examined the effects on obesity of only a limited set of store types, such as grocery stores, fast food restaurants and big-box retailers, and they have ignored that certain behavioral factors, such as could play a role in the relationship between food access and obesity. This analysis includes a comprehensive array of food-providing establishments, including limited- and full-service restaurants controlling for fruit-and-vegetables (F&V) consumption (lagged temporally) using a panel data set for the continental U.S. states covering the period 1997-2005. The...

Aggregation Theory for Incomplete Systems AgEcon
LaFrance, Jeffrey T.; Beatty, Timothy K.M.; Pope, Rulon D..
Gorman's theory of demand is extended comprehensively to incomplete systems. The incomplete systems approach dramatically increases this class of models. The separate roles of symmetry and adding up are identified in the rank and the functional form of this class of models. We show that symmetry determines rank and the maximum rank is three. We show that adding up and 0o homogeneity determines the functional form and there is no functional form restriction for an incomplete system. We prove that every full rank system and reduced rank systems with a minimal level of degeneracy can be written as a polynomial in a single function of income. A complete set of closed form solutions for the indirect objective functions of this class of models is derived. A...

Agricultural Price Seasonality and Market Failure: Examining the Net Seller Household and the Net Benefit Ratio Definition AgEcon
Vergez, Antonin.
On the basis of a household typology distinguishing between net sellers, net buyers and self sufficient, the Net Benefit Ratio (NBR), defined by Deaton (1989), is used to approximate households' first order welfare variations when price change. In this paper, we discuss both the typology's criteria and the classic formula of NBR, since they are based a) on produced and consumed quantities rather than real marketed volumes and b) on a unique selling and buying price for all surveyed households. We propose another definition of a net seller and a new NBR expression allowing the analyst to take into account market failures (MF) and price seasonality (PS), which are two constancies in developing countries. We use two sets of data (from Mexico and Mali), to...

An Analysis of Demand Elasticities for Fluid Milk Products in the U.S. AgEcon
Davis, Christopher G.; Blayney, Donald P.; Cooper, Joseph C.; Yen, Steven T..
This study examines retail fluid milk products purchase data from Nielsen 2005 home scan data. The demand for seven categories of fluid milk products were estimated: whole milk, whole flavored milk, reduced fat milk, flavored reduced fat milk, buttermilk, canned milk and all other fluid milk products. Analyses of the purchases of seven fluid milk categories based on the Nielsen 2005 home scan retail data are used to determine the roles marital status, age, race, education, female employment status and location play in the empirical estimations of aggregate demand elasticities. To derive the demand elasticities, a censored translog demand system is used. The results reveal that price and income are the main determinants of demand for fluid milk products...

An Analysis of Food Grain Consumption in Urban Jiangsu Province of China AgEcon
Zheng, Zhihao; Henneberry, Shida Rastegari.
The impacts of economic and demographic variables on the demand for food grain commodities in urban Jiangsu province of China are estimated, using both the QUAIDS and the AIDS models. Results show that the demands for wheat flour and coarse grains are price-elastic while the demands for rice and grain products are price-inelastic. Certain demographic variables show as having a significant impact on food grain demand. Finally, a decomposition of causes of changes in rice consumption over the period of 1995–2007 is performed.

An Economic-Psychological Model of Sustainable Food Consumption AgEcon
Lombardini, Chiara; Lankoski, Leena.
This paper proposes a novel economic-psychological model of individual food consumption and food waste that recognizes individuals as social and moral beings who are boundedly rational and have limited capacity for self-control. The model identifies five components of individuals’ utility that correspond to five modes of being or selves: the hedonic agent, the social agent, the moral agent, the health-conscious agent and the habits-driven agent. In the model, individuals maximize this composite utility given their budget and effort constraints. We apply the model to analyze policies that can support the adoption of sustainable food consumption practices.

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...

An Improved Method for Calibrating Purchase Intentions in Stated Preference Demand Models AgEcon
Davies, Stephen P.; Loomis, John B..
The Orbit demand model allows the magnitude of the calibration to stated purchase intentions to vary based on the magnitude of the stated quantities. Using an empirical example of stated trips, we find that the extent of calibration varies substantially with less correction needed at small stated trips (–25%) but larger corrections at higher quantities of stated visits (–48%). We extend the Orbit model to calculate consumer surplus per stated trip of $26. Combining the calibrations in stated trips and value per trip, the Orbit model provides estimates of annual benefits from 60% to 111% less than the count data model.

Análisis de la demanda de alimentos en España considerando el impacto de la dieta sobre la salud AgEcon
Angulo, Ana Maria; Mtimet, Nadhem; Gil, Jose Maria.
RESUMEN: En este trabajo se analiza la demanda de alimentos en España considerando la relación existente entre salud y dieta. Se plantea la maximización de una función de utilidad que depende de las cantidades demandadas de los distintos alimentos y del nivel de salud alcanzado, sujeto a dos restricciones: la presupuestaria y la relativa a la función de producción de salud. La solución al problema conduce a la estimación conjunta de un sistema de ecuaciones con dos componentes, una ecuación referida a la calidad de la dieta y un sistema de demanda de alimentos. Los resultados obtenidos indican, por un lado, que la introducción de la calidad de la dieta en un sistema de demanda (frente a un modelo que incluya únicamente renta y precios) modifica las...

Analysis of Import Demand for Wooden Beds in the U.S. AgEcon
Wan, Yang; Sun, Changyou; Grebner, Donald L..
The market of wooden beds in the U.S. has been flooded with imports from China and Vietnam in recent years. Static and dynamic Almost Ideal Demand System models are used to assess the import demand for wooden beds from the top seven supplying countries. The analyses reveal that the antidumping investigation on China has some temporary trade depression effect on China, but trade diversion occur to Vietnam, Indonesia, Canada, and Brazil. The formal implementation of antidumping duties since 2005 has not shown any significant effect on the trade pattern. U.S. consumers spend more on beds from newly industrialized countries and there are moderate degrees of substitution among wooden beds from most countries.
