In this study, survey data were used to develop a model to measure the relationship between a set of socio-economic characteristics of consumers and their risk perception of feed additives and growth hormones use in livestock production. Perceptions were measured indirectly by constructs based...

This study investigates alcohol consumption by women in the United States,using alternative specifications of the double-hurdle models which accommodate non-normal errors. The IHS double-hurdle model performs marginally better than the Box-Cox double-hurdle model but both models suggest very...

Impact of cholesterol information and demographic variables on egg consumption is examined using data from a consumer survey conducted by the United States Department of Agriculture (USDA). Estimation results of a double-hurdle model suggest that information and health concerns about cholesterol...

This study investigates philanthropy, an American tradition. A censored system of donation equations is estimated by full-information maximum likelihood, using data from the 1995 Consumer Expenditure Survey. Results suggest that the censored system estimates are more appropriate than the...

A nonparticipation-censored model is estimated to re-examine the determinants of extramarital affairs considered by Fair (Journal of Political Economy, 86, 1978) and Wang (Applied Economics Letters, 4, 1997). Derived from a mixed utility maximization framework, the proposed model features a...

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.

We investigate the socio-economic determinants of alcohol consumption in the United States with a Sample Selection Model (SSM). The dependent variable is log-transformed that facilitates the estimation of the model. In addition, marginal effects of explanatory variables are calculated in both...
