| A fixed-effects panel data demand model for five New York State markets is estimated to determine the differential impacts of generic fluid milk advertising by media type. Empirical results indicate that among the four media outlets, television advertising has the largest impact on per capita demand, followed by radio, outdoor, and print. Based on the estimated media-specific elasticities, media reallocation of advertising expenditures suggests that milk sales could increase significantly. The results indicate that cooperative media plan strategies developed between the New York regional advertising program and the national advertising programs would achieve the greatest benefits. |

| U.S. cheese consumption has grown considerably over the last three decades. Using a censored demand model and Nielsen Homescan retail data, this study identifies price and non-price factors affecting the demand for differentiated cheese products. Own-price and expenditure elasticities for all of the cheese products are statistically significant and elastic. Results also reveal that a strong substitution relationship exists among all cheese products. Although demographic influences are generally smaller than those related to prices and expenditures, empirical findings show that household size, college educated female heads of household who are age 40 and older, residing in the South, Central, and Western regions of the United States, as well as Black heads... |

| 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. |

| In this study, we develop and estimate a censored LA/AIDS model using household-level purchase data. In addition to imposing non-negativitity constraints, we account for the endogeneity of unit value. We address the non-negativity issue using an Amemiya-Tobin approach, which imposes the adding-up condition on both observed and latent shares. We address the endogeneity of unit value by estimating share equations and unit value equations simultaneously. Given the need to evaluate high-order probability integrals, we use a simulated probability method in the model estimation. This model is applied to estimate and analyze a demand system featuring six fish and three meat commodities, using Norwegian household data. |

| In this paper, a two-equation sample selection model is used to estimate a household demand function for salmon incorporating domestic generic advertising. The twoequation estimation procedure, based on purchase and unit value equations, allows us to handle heavily censored panel data for salmon purchases by Norwegian households and the quality effects simultaneously. Unit values of the aggregated salmon commodity calculated from the observed expenditures and quantities are hypothesized to represent the average quality of the purchased commodity. Advertising effects on both purchases and unit values are investigated. The model also allows us to separate the effects of conditional purchases and purchase probabilities. Results indicate that most (78%) of the... |

| In this study, a market segmentation approach is developed and applied to analyze U.S. household cheese purchases. The segmentation is based on household interpurchase time or the hazard rate of purchases. The hazard rate for a household belonging to a given segment is a function of household demographic and marketing-mix variables, and its baseline is assumed to follow a Weibull distribution. The model is flexible and is able to yield increasing, decreasing, or constant hazard rate functions. Four segments have been discovered in the U.S. household cheese purchase market. Two of the segments contain about 40% of the cheese purchase households, which are frequent buyers with an average interpurchase time of 2 weeks. These frequent cheese purchase... |

| By endogenizing unit value and coupon redemption, we estimate U.S. household cheese purchase, quality choice, and coupon redemption equations simultaneously. Zero purchases and missing values are taken into account in the model to correct for the selectivity bias. The correlations among the three equations are found to be significant. Empirical findings show that high quality choice significantly decreases cheese purchases, while cheese coupon usage significantly increases purchases. We find that higher income households select higher quality cheese, while larger households choose lower quality cheese. Frequent coupon redeemers are found to purchase lower quality cheese. For coupon redemption, we find that African American households redeem less while... |
