A censored system of household fat and oil demand equations is estimated with a two-step procedure, using cross-sectional data from the 1987-1988 US Nationwide Food Consumption Survey. Own price and total expenditure elasticities are close to unity and there is no evidence of gross...

Many previous studies of US cigarette and alcohol consumption have focused on single equations. However, the addictive nature of consumption suggests that it is more appropriate to model these products as a system. We propose a two-step estimation procedure and apply the procedure to a system of...

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...

Data used in recreation demand modeling are characterized by the facts that trip frequencies are non-negative integers and that consumers are often faced with alternative destinations. This paper considers these features by estimating a multivariate recreation demand model that accounts for trip...

A nonnormal and heteroscedastic double-hurdle model is used to study household expenditures on breakfast, lunch and dinner away from home in the United States. In the 1992ï¾–93 period, nearly 40% of households purchased breakfast, and about three quarters of households purchased lunch or...
