This paper provides several definitions of efficiency measures in the price space. Economic and scale aspects of inefficiency are considered to give empirical content to the measurement of efficiency when the production technology is described by cost functions models. It shows, in the...

This paper discusses the effect of the minimum wage level on the decision to join the informal job sector. We estimate a pseudo panel of the engagement in the informal sector using an IV-probit. The findings show that an increase in the minimum wage level leads to a substitution effect between...

We use information gathered from 122 studies on the effects of high school degrees on wages in different countries worldwide to carry out a meta-analysis that shows high school degrees have a statistically significant effect on wages of nearly 8%. This effect varies either when the review is...

As a result of the duality of cost and distance functions the efficiency of cost-minimizing behaviour can be compared to shadow-prizing behaviour, and conversely. In this framework we outline the form that dual efficiency measures, Muro (1982), Muro and Vera (1983), adopt for homothetic and...

The development in the tourist industry linked with the rapid growth in e-commerce has put in evidence the existence of a new customer. We empirically investigate the microeconomic determinants of the internet purchased tourist goods. We adopt a reduced form demand for online goods model,...

We outline a fairly simple method to obtain in Stata Murphy-Topel corrected variances for a twostep estimation of a heckprobit model with endogeneity in the main equation. The procedure utilizes the score option and the powerful matrix tool accum in Stata and builds on previous works by Hardin...

This paper discusses the existence of diploma earnings differences by gender in Colombia with a model of sheepskin effects based on pseudo panel data for the period 1996-2000. Our results show a significant and distinctive effect of high school and university degrees among men and women. Thus,...
