Because China has become one of the largest applicants of PCT patents, it is of interest to compare the quality of Chinese and non-Chinese applications. We extend a quality index based on internationally comparable citation data from international search reports (ISR) to consider foreign,...

Multiple institutional affiliations occur when an academic belongs to more than one organisation. Recent research shows an increase in multiple affiliations, but evidence on roles and motivations is mainly anecdotal. We develop in this study a typology of co-affiliations which identifies four...

In the transition to decarbonized energy systems, Power-to-Gas (PtG) processes have the potential to connect the existing markets for electricity and hydrogen. Specifically, reversible PtG systems can convert electricity to hydrogen at times of ample power supply, yet they can also operate in...

Employment responses to the COVID-19 crisis differed widely across German local labour markets at the beginning of the pandemic, with differences in short-time work rates of up to 20 percentage points. We show that digital capital, and to a lesser extent working-from-home, were essential for the...

Because judges exercise discretion in how they handle and decide cases, heterogeneity across judges can affect case outcomes and, thus, preferences among litigants for particular judges. However, selection obscures the causal mechanisms that drive these preferences. We overcome this challenge by...

This paper analyses the relationship between past innovation output, competition, and future innovation input in a dynamic econometric setting. We distinguish two dimensions of competition that correspond to the concepts of product substitutability and entry barriers due to fixed costs. Based on...

The paper aims at testing Florida's concept of the Creative Class using panel data for 323 West German regions for the time period 1975 2004. Applying a dynamic system approach based on GMM, we find that the local concentration of the Creative Class has predictive power for the economic...

Although there seems to be consensus in the literature that venture capital investors increase the innovation output of their portfolio companies, there is little evidence about how investor type (governmental vs. private) and transaction structure (syndicated vs. non-syndicated) moderate this...

The viability of modern open science norms and practices depend on public disclosure of new knowledge, methods, and materials. Aggregate data from the OECD show a broad shift in the institutional financing structure that supports academic research from public to private sponsorship. This paper...

Inter-departmental innovation collaboration facilitates innovation performance. At the same time, it has been identified as source of increased coordination costs. Using organizational information processing theory, this paper builds and tests hypotheses on the costs and benefits of...
