In the last decades, innovation activity has been defined by an increasing complexity and a faster pace of the underlying technological change. Accordingly, several studies have shown that competitive systems of innovation benefit from being able to build upon a wide but integrated spectrum of...

In 2010 China was the world's fourth largest filer of patent applications. This followed a decade of unprecedented increases in investment in skills and Research and Development. If current trends continue China could rank first in the very near future. We provide evidence that the growth in...

Deutsche Konzerne wie Volkswagen, Daimler, Bosch und Siemens gehören zu den forschungsstärksten der Welt. Trotz gestiegener Aufwendungen für Forschung und Entwicklung im Ausland verliert der Heimatstandort für diese Unternehmen nicht an Bedeutung. Ausländische Unternehmen tragen in...

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...

Our data from 351 innovating firms for the years 2001–2012 generally suggest that patentable ideas are strongly linked to the mobility of individual inventors, or that the knowledge flows transmitted are sticky inventor-specific. In other words, the larger the knowledge pool of an inventor...

In this work, we develop and apply a methodology to estimate technology-specific R&D investments at firm level and then use these to test some arguments that have become central in the innovation literature. In particular, we first combine R&D investments with patent data of the world top R&D...

A temporary change in pay to employed inventors around the time of patent application has been observed in a number of countries. A theoretical model is here developed to provide an explanation to said findings based on the idea that inventors may be able to use the knowledge previously...

We study the relationship between patents and actual product innovation in the market, and how this relationship varies with firms' market share. We use textual analysis to create a new data set that links patents to products of firms in the consumer goods sector. We find that patent filings are...
