| Stochastic kernels are used in this paper to investigate intra-distribution dynamics in the world per capita intakes of proteins and fats. The analysis of actual transitions over the last 40 years indicates that lagging countries improved their position relative to the leading. Long-run (steady-state) distributions have been obtained using estimated intake change models. These distributions have been compared to “virtual” ones revealing that the income elasticity of demand or equivalently the rate of growth in per capita income does have a strong influence on the dispersion of intakes at the steady-state. |

| Indonesia is an emerging market for beef and cattle exports so estimates of income and price elasticities may help analysts predict future demands. In contrast to developed countries, where meat demand studies often use aggregate data, Indonesian studies rely on household surveys, with unit values (ratios of expenditures to quantities) used instead of market prices. Elasticities estimated from unit values can be subject to various quality and measurement error biases. In this paper, data from 29,000 households on Java are used to estimate a demand system for beef, chicken and other meat groups, and the extent of bias from commonly used estimation strategies is evaluated. |

| Livestock industries are significantly affected by changes in consumer behaviour. In order to add value to meat and livestock production, many firms and farms are supporting the development of new products – these products can differ by credence attribute, by degree of processing and by marketing strategies. The literature suggests that one of the most important determinants of success in product innovation is an understanding of the market the product is introduced into. In this report consumer preferences for meat products, by animal species including minor meats, and by type of processing are examined. Responses to economic variables such as price, advertising and income are identified as are responses to food safety and meat related health issues.... |

| 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... |

| When using household-level data in examining consumer's 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 in the estimation can lead to biased parameter estimates. In this paper we investigate the household's demand for six types of whole grain and non-whole grain breakfast cereals and products using a censored Almost Ideal Demand System (AIDS) and estimate the parameters of the demand system via Bayesian methods. Using 2006 ACNielsen Homescan data we find that demand for whole grain and non-whole grain ready-to-eat cereals is less responsive to changes in prices; demand for whole-grain bars and non-whole grain hot... |

| The development of innovative functional food products is a major trend in today's food industry. The growth of this industry is driven by increased consumer awareness of their own health deficiencies, increased understanding of the possible health benefits of functional foods, development in formulation technologies, a positive regulatory environment and changing consumer demographics and lifestyles. While there has been a proliferation of omega-3 products such as milk, eggs, yogurt, and margarine in the Canadian food market, very little is known about consumers of omega-3 products. In our study we use ACNielsen HomescanTM data combined with ACNielsen Panel TrackTM survey data to develop profiles of omega-3 consumers in Canada. The focus of the study is... |

| People with low incomes tend to make less healthy consumption choices than do high income people. In the case of food, agricultural economists have investigated whether this is due to the cost of a healthy diet. Studies of various aspects of the nutrition-income nexus have generally been inconclusive. We investigate a different possibility, motivated by the fact that low income individuals are most likely to be smokers, which cannot be due to limited budgets. Drawing on a body of related literature, we develop a model in which income serves not only as a budget constraint but also as a source of future utility. We test the model by estimating logistic models of beginning and quitting smoking. We find support for the idea that low income consumers make less... |

| A censored Almost Ideal Demand System (AIDS) and a Quadratic Almost Ideal Demand System (QUAIDS) were estimated in modeling non-alcoholic beverages. Five estimation techniques were used, including the conventional Iterated Seemingly Unrelated Regression (ITSUR), two-stage methods such as the Heien and Wessells (1990) and the Shonkwiler and Yen (1999) approaches, the generalized maximum entropy method and the Amemiya-Tobin framework of Dong, Gould and Kaiser (2004). Our results based on various specifications and estimation techniques are quantitatively similar and indicate that price elasticity estimates have a greater variability in more highly censored non-alcoholic beverage items such as tea, coffee and bottled water as opposed to less censored... |
