Traditional approaches to measurement conditional probabilities of leaving welfare do not deal with unemployment benefits data in a proper way leading thus to biased estimates of unemployment-employment transition probabilities. In fact, these approaches overestimate hazard rates and hence...

In the presence of selection bias the traditional estimators for pseudo panel data models are inconsistent. This paper discusses a method to achieve consistency in static linear pseudo panels in the presence of selection bias and a testing procedure for sample selection bias. The authors'...

The authors use information gathered from 122 studies on the effects of high school diplomas on wages in different countries worldwide to carry out a meta-analysis that shows high school diplomas have a statistically significant effect on wages of nearly 8 percent. This effect varies whether the...

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,...

In the presence of selection bias, traditional estimators of pseudo panel data are inconsistent. In this paper, the authors derive the conditions under which consistence is achieved in pseudo-panel estimation and propose a simple test of selection bias. Specifically, they propose a Wald test for...
