In this paper, human capital investments are evaluated by assuming heterogeneous returns to schooling. We use the potential outcome approach to measure the causal effect of human capital investments on earnings as a continuous treatment effect. Empirical evidence is based on a sample of West...

This paper aims at investigating the determinants of self- employment within a structural model of discrete choice under uncertainty. The basic idea of our approach centres around Knight's (1921) famous view of entrepreneurs receiving risk-adjusted income that has to exceed the income of...

In this paper, the efficiency of human capital investments is evaluated in the light of inadequate educational careers and skill obsolescence. Assuming heterogeneous returns to schooling and overeducation we use the potential outcome approach to measure the causal effect of human capital...

In Germany, the skill structure of wages remained stable in the last two decades while employment of the low skilled deteriorated considerably relative to employment of the high skilled. This paper analyses the impact of technical progress on the skill structure of employment and wages by means...

This paper analyzes the interday stability of the price process using transaction data. While the vast majority of empirical studies on the microstructure of financial markets rests on the tacit assumption that observed prices are generated by a time-invariant price process, we question this...
