The validity of family background variables instrumenting education in income regressions has been much criticized. In this paper, we use data of the 2004 German Socio-Economic Panel and Bayesian analysis in order to analyze to what degree violations of the strong validity assumption affect the...

Are differences in inventor productivity due to differences in inventors’ skills or differences in the capabilities of the firms they work for? We analyze a 37-year panel that tracks the patenting of U.S. inventors and find strong evidence for serial correlation in inventors’ productivity....

Education is argued to be an important driver of the decision to start a business. The measurement of its influence, however, is difficult since it is considered to be an endogenous variable. This study accounts for this endogeneity by using an instrumental variables approachand a data set of...

Education is a well-known driver of (entrepreneurial) income. The measurement of its influence, however, suffers from endogeneity suspicion. For instance, ability and occupational choice are mentioned as driving both the level of (entrepreneurial) income and of education. Using instrumental...

We study hiring in a labor market where worker ability can only be observed on-the-job, but quickly becomes public information after labor market entry. We show that firms in these markets have a socially inefficient incentive to hire low talented, experienced workers instead of more promising...

We study how workers in production teams are affected by the temporary absence and replacement of a coworker. When a substitute coworker is absent, the remaining coworkers produce less output per working time. They compensate for this by increasing their working time at the expense of the (less...

We investigate whether national borders within Europe hinder the assortative matching of workers to firms in a high skilled labor market. We characterize worker productivity as the ability to contribute to physical output and define firm productivity as the capacity to transform physical output...
