The development of inventor networks is characterized by the addition of a significant number of new inventors, while a considerable number of incumbent inventors discontinue. We estimate the persistence of knowledge in regional inventor networks using alternative assumptions about knowledge...

We investigate the stability of cooperative relationships between inventors and consequences for the characteristics and patent productivity of the respective regional innovation systems (RIS). The empirical analysis is for nine German regions over a period of 15 years. We find a rather high...

This paper explores entrepreneurship in biotech through the in depth analysis of four new ventures located in the Upper-Rhine Biovalley. One of the strengths of this paper is the presence of both successful cases of entrepreneurship and of cases of failures. This gives the opportunity to discuss...

How does patent examination influence access to finance for innovative firms? We exploit a reform to the UK's patent system that introduced substantive examination to the patent application process, improving the information available to potential investors on the value of firms' patents. Using...

The costs of low-carbon energy fell dramatically over the past decade, leading to rapid growth in its deployment. However, many challenges remain to deploy low-carbon energy at a scale necessary to meet net zero carbon emission targets. We argue that developing complementary technologies and...

We study how business taxes affect establishments' R&D activities. Relying on geocoded panel data targeting the universe of R&D-active establishments in Germany, we exploit around 7,300 changes in the local business tax rate over the period 1987-2013 for identification. Using event study...

In this paper we replicate most of the stylized facts characterizing the decline in business dynamism in the USA highlighted by Akcigit and Ates (2021) and provide an explanation of their emergence by means of a macroeconomic agent-based model populated by two types of firms: innovators who...
