Responding to mounting evidence of the association between whole-grain consumption and a reduced risk of heart problems and other diseases, as well as an increased probability of body weight maintenance, the US Government has strongly encouraged its citizens to increase consumption of whole...

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...

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...

Heien and Wessells' two-step estimator for the multivariate sample-selection model has been used extensively during the past 15 years. A modified version of it, with slightly different selectivity regressors, has also appeared in the empirical literature. Both estimators are unfounded and...

Cigarette consumption by US women is investigated. The dependent variable is discrete and censored at zero. The Gaussian hurdle model and negative binomial hurdle model are used to accommodate zero observations in the sample. Elasticities derived from the two models are extremely close.

In 2002, the US Environmental Protection Agency (USEPA) established a voluntary environmental program called the Climate Leaders (CL) Program. Participating firms developed greenhouse gas emissions inventories, set emissions reductions goals, and annually reported progress toward those goals....

The roles of Supplemental Nutrition Assistance Program (SNAP) and parental resources in household food insecurity are investigated with a endogenous ordered probability model. Data for husband-wife families with children from the 2010 and 2011 Current Population Survey are used. SNAP...
