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...

This paper postulates that the effect of unemployment benefits on the hazard rates changes considerably using a traditional duration model that uses only unemployment insurance (UI) data, or deals with unemployment assistance (UA) as a mere extension of UI, instead of an extra time duration...

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...

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...

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...
