A quasi-maximum-likelihood estimator is proposed and applied to a censored Translog demand system for foods, using a sample of food stamp recipients in the United States. The procedure produces remarkably close parameter and elasticity estimates to those of the simulated-maximum-likelihood...

The relationship between Food Stamp Program (FSP) participation and household food insecurity (FI) is investigated using data from the 1996–1997 National Food Stamp Program Survey. Endogeneity of FSP participation is accommodated with an instrumental variables approach. In contrast to other...

Heckman's sample-selection model is generalized to the multivariate case and used to estimate demands for cigarettes, beer, and wine by individuals in the United States. The specification allows correlations between the error terms of multiple selection and level equations, and nests the popular...

The dependent double-hurdle model is generalized by an inverse hyperbolic sine transformation of the dependent variable. The resulting specification features a flexible parameterization, accommodates heteroskedastic errors, and nests a range of common limited dependent variable models. Results...

A consistent two-step estimation procedure is proposed for a system of equations with limited dependent variables. Monte Carlo simulation results suggest the procedure outperforms an existing two-step method. Copyright 1999, Oxford University Press.

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...

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...

We investigate the effect of physical activity on bodyweight and the gender differences in such effects, following the copula approach to endogenous switching regression. Using data from the 2006 Behavioral Risk Factor Surveillance System (BRFSS), we find differentiated effects of...

This paper investigates the extent to which off-farm employment by the farm couples affects food expenditures at home and away from home, by developing and estimating a dual treatment effect model. Off-farm employment by a farm operator is found to increase food expenditure away from home, but...
