The relationship between innovation and firm survival is analyzed for the population of German laser source producers from the beginning of the industry until 2005. Innovation effort is approximated by the generation of high quality patents in laser sources technology (IPC H01S) and by having...

We examine the role of universities in knowledge production and industrial change using historical evidence. Political shocks led to a profound pro-science shift in German universities around 1800. To study the consequences, we construct novel microdata. We find that invention and manufacturing...

Employing a quantitative, data-driven tool - the Triple Helix Indicator - to microdata of firms in Germany, we develop an evidence base for innovation-policy strategies. We aim to answer the question which level of government (local, regional, national) might be most effective for strategic...

The paper tests empirically the role of knowledge stocks to explain the regional distribution of Germany's biotechnology founders. We present an unique approach to highlight the role of knowledge spillovers as we differentiate according the local embeddedness and research affinity of founders....

We examine the role of universities in knowledge production and industrial change using historical evidence. Political shocks led to a profound pro-science shift in German universities around 1800. To study the consequences, we construct novel microdata. We find that invention and manufacturing...

This paper studies the effect of regional spillovers on the rate of firm formation in two major West German industries for the time period from 1989 to 1993. I exploit regional variations in firm formation at the county level to identify the effects of historically given industry structure and...
