We assess the relevance of formal education for the productivity of the self-employed and distinguish between opportunity entrepreneurs, who voluntarily pursue a business opportunity, and necessity entrepreneurs, who lack alternative employment options. We expect differences in the returns to...

We analyze the effect of education on wages using German Socio-Economic Panel data and regional variation in mandatory years of schooling and the supply of schools. This allows us to estimate more than one local average treatment effect and heterogeneous effects for different groups of...

We assess the relevance of formal education for the productivity of the self-employed and distinguish between opportunity entrepreneurs, who voluntarily pursue a business opportunity, and necessity entrepreneurs, who lack alternative employment options. We expect differences in the returns to...

A pseudo-panel approach is used to estimate the returns to schooling (RTS) in Costa Rica. Thisapproach ameliorates the “ability†bias due to the correlation between the level of education and nonobservablecharacteristics of the individual.We found that RTS are higher for older...

This discussion paper describes the extent of social inequalities both within and between the countries of the European Union. In the first three chapters we address the micro level of individual life courses: education, employment and income. The following chapters analyse the societal...

This paper examines the effect of measurement error in the dependent variable on quantile regression, because unlike OLS regression, even classical measurement error can generate bias. I examine the pattern and size of the bias using both simulation and an empirical example. The simulations...

This paper studies the causal effects of graduating from university with an honors degree on subsequent earnings. While a rich body of literature has focused on estimating returns to human capital, few studies have analyzed returns at the very top of the education distribution. We highlight the...

This paper studies the effect of firm entry deregulation on the returns to skill and education. We use matched employer-employee data for the universe of workers and firms in Portugal and exploit a comprehensive episode of entry deregulation, unique in the industrialized world, as a...

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'...
