We study the role of professional networks in facilitating emigration of Jewish academics dismissed from their positions by the Nazi government. We use individual-level exogenous variation in the timing of dismissals to estimate causal effects. Academics with more ties to early émigrés...

Empirical research in organizational ecology has mainly focused on analyzing founding and mortality rates using life history data of the organizations. We try to extend this approach in our study in a number of ways. In contrast to most empirical studies in organizational ecology, we chose a...

The aim of the paper is to evaluate the role of universities in the innovation process. Against the background of theoretical considerations about the interrelation of innovation and the adaptation of external resources, the effects of university-based (knowledge) resources - together with other...
