Nationwide wages at public universities in Venezuela are established by government based on a five-category system, whose requirements include research and tenure. Generally, professors show delay in promotion, probably due to neglecting research, prevalence of lecturing and lack of monetary...

Fish demand patterns in nine Asian countries were investigated using a multistage budgeting framework allowing a disaggregated approach to analysing fish consumption. This paper highlights the heterogeneity of fisheries products in terms of species, sources and cultural responses of consumers,...

In this paper, we propose a flexible, parametric class of switching regime models allowing for both skewed and fat-tailed outcome and selection errors. Specifically, we model the joint distribution of each outcome error and the selection error via a newly constructed class of multivariate...

The dhreg command implements maximum likelihood estimation of the double-hurdle model for continuously distributed outcomes. The command includes the option to fit a p-tobit model, that is, a model that estimates only an intercept for the hurdle equation. The bootdhreg command (the bootstrap...

The present paper proposes a strategy for estimating panel data models in the presence of sample selection and endogeneity arising from endogenous explanatory variables and unobserved heterogeneity. We propose three alternative tests for selection bias and estimation strategies to correct for...
