| The double-hurdle and infrequency-of-purchase models are applied to pork and cheese consumption using the 1987-88 Nationwide Food Consumption Survey data. The models are generalized with the inverse hyperbolic sine transformation in the dependent variable, and this transformation results in a more flexible parameterization and error distribution than the untransformed models. Nonnested LR tests suggest that the IHS double-hurdle model provides better characterization of the data-generating process in household pork consumption than the IHS infrequency-of-purchase model but the elasticities derived from these models are similar. For household cheese consumption, the two models fit the data equally well. The IHS double-hurdle model and the IHS... |

| 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... |

| A heteroscedastic double-hurdle model is used to investigate household butter consumption in the United States. Results suggest that failure to incorporate heteroscedastic errors may lead to unreliable elasticity estimates. Decomposition of the effects of variables leads to insightful information and makes the double-hurdle model a more useful tool in micro demand analysis. Larger and higher-income households are more likely to consume butter than others and also consume more, but income elasticity is very small. Age, region, and seasonality are among the other significant determinants of household butter consumption. |

| A body of literature has addressed off-farm work by the farm household, but little is known about the association between off-farm work and food consumption. This paper investigates the extent to which off-farm employment by the farm operator and the spouse affects food expenditures at home and away from home. A dual treatment effect model is developed to estimate a simultaneous equation system of four food categories consumed at home and aggregate food away from home, with binary endogenous off-farm employment by the operator and spouse. Off-farm employment by farm operator and spouse both increase food expenditure away from home, while operator’s off-farm employment decreases staple food consumption at home. Socio-demographic characteristics also play... |

| A nonnormal and heteroskedastic double-hurdle model is used to study household expenditure on breakfast, lunch and dinner away from home in the United States. In the 1992-93 period, nearly 40 percent of households purchased breakfast, and about 75 percent of households purchased lunch or dinner in a two-week period. Wife's employment has a positive effect on the probability and level of lunch and dinner expenditures but not on breakfast expenditures. Income effects are al statistically significant and positive. The role of household composition, other demographics and region are also important. |

| This paper examines the determinants of household alcohol expenditures by using a nonnormal and heteroscedastic double-hurdle model to accommodate zero observations in the sample. The model is a generalization of the double-hurdle model estimated in previous studies of alcohol consumption. We also examine the effects of explanatory variables by calculating and decomposing the elasticities. Findings support the use of a more generalized error distribution. Income, region, education, and household demographics are among the significant determinants of alcohol expenditures. |

| This study examines retail fluid milk products purchase data from Nielsen 2005 home scan data. The demand for seven categories of fluid milk products were estimated: whole milk, whole flavored milk, reduced fat milk, flavored reduced fat milk, buttermilk, canned milk and all other fluid milk products. Analyses of the purchases of seven fluid milk categories based on the Nielsen 2005 home scan retail data are used to determine the roles marital status, age, race, education, female employment status and location play in the empirical estimations of aggregate demand elasticities. To derive the demand elasticities, a censored translog demand system is used. The results reveal that price and income are the main determinants of demand for fluid milk products... |
