Scanner data for breakfast cereals are used to estimate demand elasticities for six supermarket stores in two distinct socio-economic areas. Three stores are in low-income locations and three are in high-income locations. A time series cross-section model is estimated for five product categories across six cross sections over forty-two weeks. Results show lower-income shoppers to have more elastic demands for four of the five product categories: private label cold cereals, the top ten brands of cold cereals, all other brands of cold cereals, and hot cereals. Price is not statistically significant for a fifth product category, snack cereals. |

This paper reports results from a pilot U.S. national telephone survey on genetically modified foods (vegetable oil, cornflake cereal, and salmon). The survey featured contingent valuation in which respondents chose between the GM and non-GM alternatives. The binary and multinomial logit models yield estimated willingness to pay to avoid the GM alternatives. Perceived risk of GM food is an important determinant of GM choice along with the price. Respondents are willing to pay 41.2%, 31.4%, 40.9%, and 52.5% of the base prices to avoid GM vegetable oil, GM cornflakes, GM-fed salmon, and GM salmon, respectively. |

In 2001, Taiwan enacted a law for genetically modified food (GM foods) labeling. Beginning January 1st 2003, food containing more than 5% of GM ingredients must be labeled. Taiwan imports most of its soybeans from the United States. In order to assess the effects of the new policy, a telephone survey was conducted in 2002. A total of 257 interviews were completed. A typology of consumers' attitudes towards GM foods is constructed from the use of a multiple correspondence analysis and a classification method. Four profiles are identified: proponents, 52%, moderate opponents, 32.5%, extreme opponents, 12.5%, and those with no opinion, 5.5%. |

Currently over 30% of American adults are obese, more than twice the percentage prevalent in 1980 (American Obesity Association). At the same time, almost 65% adult Americans are said to be overweight. Such high prevalence levels are a major public health concern. Both overweight and obesity are associated with increased health risk for chronic diseases such as heart disease, type 2 diabetes, high blood pressure, stroke, fatty liver disease and some forms of cancer. In this paper we explore the factors that contribute to increasing rates of obesity and overweight, and study the differences in years 1996 and 2002. We use a multilevel econometric approach to model the four classifications of body mass index (BMI) obese, overweight, healthy and underweight... |

We present in this study an agricultural household model that describes the joint production-consumption decision making of Chinese rural households under imperfect market. We conclude that the marginal value of a food product consumed is the sale price if there is a net sale for this food item; it is the purchase price if there is a net purchase; and it is the shadow price if there is no purchase or sale. A preliminary empirical food estimation analysis confirms that it provides superior demand estimates to use these "effective prices" rather than traditionally used purchase prices or weighted average of sale and purchase prices in rural food demand analysis in less developed countries (LDCs). |

Since its economic reform, China has changed significantly as it makes its transition from a centrally-planned to a consumer-oriented economy and thus has gradually increased household income and changed consumption patterns in urban China. This study attempts to provide an in-depth understanding of heterogeneous consumer patterns in urban China by developing a multi-stage censored demand system using household data. Specifically, this study develops an economic model considering heterogeneous consumption patterns across households and commodity groupings and estimates econometric models of a Quadratic Almost Ideal Demand System (QAIDS) using household data. Three methodologies are integrated including constructing a multi-stage demand system,... |
