| A growing trend in demand analysis during the last two decades is the use of household survey data. Detailed demographic information collected in these surveys allows treatment of heterogeneous preference and the typically large sample also allows estimation of large demand system that are otherwise not possible with aggregate time series. However, the use of household-level data is complicated by the censoring of the dependent variable especially for systems with disaggregated commodity definitions. To overcome the numerical problem of evaluating truncated multi-dimensional error term distributions, a Quasi-maximum likelihood method is used to estimate a censored 9-commodity demand system for a sample of urban Mexican households. The impacts of... |

| A two-step model with sample selection is applied to panel data of U.S. households to estimate at-home demand for fluid milk and cheese, incorporating advertising expenditures. The model consistently accounts for sample-selection bias, unobserved household heterogeneity, and temporal correlation. Generic advertising programs for fluid milk and cheese were effective at increasing conditional purchase quantities, with very little effect on the probability of purchase. In contrast to aggregate studies, the long-run generic advertising elasticities for cheese were larger than for those of fluid milk. Advertising response varied considerably across sub-product classes, while branded advertising expenditures were largely insignificant. |

| An endogenous switching regression model is used to examine how meal planner health knowledge affects dietary fat intake. Ethnicity, income, meal planner age, being on a low-fat diet, and other health awareness behaviors had significant effects on health knowledge. After controlling for differences in household and meal planner characteristics, intake of total and saturated fat was found to depend on health knowledge status. |

| U.S. fluid milk consumption has changed dramatically since the early 1970s. Whole milk accounted for over 81% of commercial fluid milk disappearance in 1970. By 1993, this percentage was less than 39%. A three-equation fluid milk demand system is estimated for fluid milks that vary by fat content. The household panel data set used includes over 4,300 households who recorded fluid milk purchased for at-home consumption over a 12-month period. Given that many of these households did not consume one or more of the three milk types, the econometric model explicitly incorporates the censored nature of these commodity demands. Own and cross-price and substitution elasticities are estimated along with effects of household demographic characteristics. |

| This analysis examines the determinants of organic food purchase behavior of a random sample of U.S. food shoppers. We analyze food expenditures conditional upon whether a household purchases organic foods. The results from our econometric modeling effort identify shopping venue, awareness of the organic label, positive beliefs toward organic foods, a positive attitude toward cooking, and a lack of religious affiliation as being important determinants of organic food purchases. Income was not found to significantly affect the decision to buy organic foods. Our results suggest that the limiting factors of the organic food market are search cost, dietary patterns, and awareness of the organic food label. Given the recent “Wal-Mart” effect on the organic food... |

| Increased availability of scanner-based panel data has enabled researchers to better understand nondurable commodity purchase dynamics. In this study, we focus on one component of the purchase process--when to buy. The relationship between the discrete purchase decision and a set of household and purchase characteristics is quantified using a simulated maximum-likelihood procedure. Given the longitudinal nature of our data, unobserved heterogeneity is addressed by adopting an auto-correlated error structure. Our empirical application is household purchases of cheese. We find evidence of significant persistent unobservable household heterogeneity, which is not eliminated by the inclusion of lagged exogenous variables. |

| The dynamics of cheese purchases is analyzed by estimating a series of econometric models of duration based on a 170 week household panel. Besides purchase quantity and price data, information with respect to coupon use and household demographic characteristics are used in a variety of models which build upon each other in terms of assumed distribution of interpurchase time, effect of previous purchases, role of demographic characteristics and effect of unobserved interpurchase time heterogeneity. Likelihood ratio tests clearly reject the null hypothesis that coupon use has no impact on cheese purchase timing. |
