Última Estimation of a Censored Demand System in Stratified Sampling: An Analysis of Mexican Meat Demand at the Table Cut Level. AgEcon Lopez, Jose Antonio; Malaga, Jaime E.. Evidence of meat trade in the form of table cuts suggests that consumer preferences and tastes vary across meat cuts. Unlike previous studies, this paper estimates demand elasticities at the table cut level from a Mexican survey of household incomes and expenditures, which is a stratified sample. The study uses the two-step estimation of a censored demand system proposed by Shonkwiler and Yen (1999) but incorporates stratification variables into the estimation procedure. Parameter estimates are reported and its standard errors are approximated by using the bootstrap procedure.

Ano: 2009 URL: http://purl.umn.edu/46294 ADULT EQUIVALENT SCALES REVISITED AgEcon Demoussis, Michael; Mihalopoulos, Vassilis. Use of the Tobit model for estimation of adult equivalent scale (AES) parameters and expenditure equations presupposes that zero observations represent exclusively corner solutions. This paper tests for the underlying causes of zero observations and estimates accordingly the AES parameters, the household size in adult equivalents and the resulting expenditure equations and consumption profiles. The empirical application concerns Greek household "soft" and "hard" cheese consumption. The statistical results indicate that for the examined cheese categories the "double hurdle participation" model adjusted for non-normality and heteroskedasticity is the appropriate model for the estimation of AES parameters and expenditure equations.
