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.

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.

The urgent need to improve livestock productivity in sub-Saharan Africa in order to keep pace with expected increases in demand for meat and milk is very topical. Breed improvement provides key entry points for increasing productivity in cattle populations. However, there are tendencies for breed improvement programs to focus on single, market driven traits such as milk or meat production in isolation of environmental constraints and broader livestock system functions which cattle assume in developing countries. This potentially leads to genotypes that are not well adapted to the environment and not capable of performing the multiple roles that cattle assume in cattle production systems of developing countries. In developing countries, many important...

Scientific evidence clearly indicates that consumption of raw milk carries substantial disease-inducing health risks. While federal U.S. policy mandates that milk moving in interstate commerce be pasteurized; within 41 of 50 states, raw milk can be obtained for consumption. Warning labels notwithstanding, a segment of U.S. consumers pays higher prices for higher-risk raw milk than for either organic or conventional milk. The behavioral factors leading to raw milk consumption are explored. The paternalistic regulatory options for reducing the risk associated with drinking raw milk are identified. Implications for fresh produce sold directly from farms to consumers or through farmers markets are drawn.

Residential consumers remain reluctant to choose new electricity suppliers. Even the most successful jurisdictions, four U.S. states and other countries, have had to adopt extensive consumer education procedures that serve largely to confirm that choosing electricity suppliers is daunting. Electricity is not unique in this respect; numerous studies find that consumers are generally reluctant to switch brands, even when they are well-informed about product characteristics. If consumers prefer not to choose, opening regulated markets can reduce welfare, even for some consumers who do switch, as the incumbent can exploit this preference by raising price above the formerly regulated level. Policies to open markets might be successful even if limited to...

Early GM traits were obtained by transferring genes across species, largely from soil bacteria. Part of the consumer resistance to them has been their transgenic nature. Recently, breakthroughs have occurred using intragenic bioengineering where genes are moved long distances within a specie, for example in potato, and without antibiotic markers. The objective of this research is to assess consumers’ acceptance and willingness to pay (WTP) for new intragenic fresh potato, tomato, and broccoli with higher levels of antioxidants and vitamin C, which are consumer traits. To elicit consumer valuations, a new series of experimental auctions were conducted in 2007 that built upon methodology developed in our earlier research. WTP was assessed in a multi-round...

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...

With this study, we investigate the effects of changes in economic factors on body weight by constructing a utility theoretic model. The model is empirically estimated by combining data on individuals’ body weight, demographic and physical activity information, and statelevel measures pertaining to the prices of food away from home, food at home, and wages. By combining these data sources, we aim to estimate directly the weight effects of price and income changes. The empirical analysis suggests that decreasing the price of food at home could decrease body weight, a finding which has important public policy implications.

This paper considers a setting in which the acquisition of human capital entails a change of location in social space that causes individuals to revise their comparison groups. Skill levels are viewed as occupational groups, and moving up the skill ladder by acquiring additional human capital, which in itself is rewarding, leads to a shift in the individual’s inclination to compare himself with a different, and on average better-paid, comparison group, which in itself is penalizing. The paper sheds new light on the dynamics of human capital formation, and suggests novel policy interventions to encourage human capital formation in the aggregate and, at the same time, reduce inter-group income inequality.

We explore whether environmental motivation affects environmental behavior by focusing on volunteering. The paper first introduces a theoretical model of volunteering in environmental organizations. In a next step, it tests the hypothesis working with a large micro data set covering 32 countries from both Western and Eastern Europe using several different proxies to measure environmental motivation. Our results indicate that environmental motivation has a strong impact on individuals’ voluntary engagement in environmental organizations. A higher level of environmental motivation due to higher environmental moral standards may lead to a stronger voluntary involvement in environmental organizations.

The purpose of this study is to analyze the demand responses of Indonesian households to food prices, income changes and other socioeconomic factors. The underlying assumption here is that inadequate information on household food expenditure patterns which vary across income groups and regions may have its contribution to the persistence of food insecurity. We use the Indonesian Family Life Survey data and methodologically we employ an extended form of the Quadratic Almost Ideal Demand System model which includes demographic and regional factors. Results reveal the well known pattern that food demand behavior varies significantly between urban and rural households as well as income groups. The poorest households consume relatively more staple food as well...

Unlike in developing countries, there tends to be no problem of access to water, electricity, and heating for private households in transition countries. However, transition countries have a considerable amount of low-income households, and the problem of affordability of these environmental-related utility services remains urgent. Welfare economics literature suggests to neglect affordability aspects by separating allocative from distributive impacts of pricing. In practice, this separation runs the risk of rendering impossible any sustainability-oriented price reform. An Institutional Economics approach takes competing objectives into account. From this viewpoint it appears to be worth investigating the affordability-concept. Although the...

Some food markets are dominated by high quality and standard quality segments, whereas medium quality products are almost absent. A modeling framework with asymmetric information regarding true quality of the products and the resulting lack of consumer confidence is presented. Uncertainty regarding the quality of alleged medium quality products provides certain consumer groups to divert consumptions away from medium quality to either standard or high quality products. These countervailing incentives explain the missing medium quality products. Empirical examples are given to motivate the model.

The aim of this paper is to analyse patterns of private individual giving to Cultural Heritage institutions in Italy. Based on the emerging economic literature on pro-social behavior, we carried out a Contingent Valuation survey to assess individuals’ willingness to donate to museums and heritage organizations according to different conditions and set of incentives. Our findings reveal that intrinsic motivations and accountability of the recipient institutions may be more effective drivers for eliciting charitable giving than the usually proposed fiscal incentives. The results provide avenues for future empirical research and policy suggestions for fund raising cultural institutions.
