Individuals and firms can improve their performance through collaboration and competition. However, it is still an open question how collaboration and competition schemes can be optimally designed and incentivized in order to exploit their full potential. Jonas Heite investigates this question by assessing efforts to stimulate R&D collaboration and by examining properties as well as underlying mechanisms (e.g., effort, risk, confidence and stress) of ability configurations in contests. Based on three large-scale economic studies covering laboratory, field and natural experiments, the author applies novel and sophisticated econometric methods to provide causal empirical evidence that yields important implications for policymakers, managers and researchers.
Working and interacting in foreign languages is widespread. While the relationship between language and behavior has been discussed for many years, empirical evidence for behavioral effects of foreign language use is surprisingly scarce. Stefan Nothelfer has conducted a series of laboratory studies to investigate and disentangle effects of language and culture on creativity and cooperation, important behavioral foundations of innovation. He draws insights from a large cross-country dataset with pairings between three languages, using a custom-built mobile laboratory. The author’s findings challenge theories of linguistic relativity, foreign language effects, and cultural accommodation, and enrich the empirical basis for fundamental research on language and behavior.
The digital transformation of the business environment and its impact on firm performance is of central interest in economics and management. However, it is still an open question how firms should optimally align their business models and strategies for the digital era. Daniel Wittenstein investigates this question by generating novel insights from hidden champions and by developing a machine learning-based approach for measuring firm-level digitalization.
Stimulating entrepreneurial activity has become a priority for government policy around the globe. This dissertation investigates efforts to promote entrepreneurship at the individual, company, and regional level in three selfcontained essays. First, at the individual level, the effectiveness of entrepreneurship education in nurturing entrepreneurial skills, attitudes, and intentions is examined among high school students. Second, at the company level, the potential of short-term support schemes to accelerate the growth of early-stage ventures is explored. Third, at the regional level, the development of entrepreneurial activity precipitated by transformational events at large corporations presents the most extensive unit of analysis. Together these studies inspire a nuanced discussion of how entrepreneurship can be encouraged at different stages of development and in various settings.
Christian P. Steinle analysiert in seiner empirischen Studie Erfinder als Individuen in kreativen Prozessen im Hinblick auf die Wechselwirkungen von Persönlichkeit, Leistung und Position im Erfindernetzwerk. Der Schwerpunkt der Untersuchung liegt dabei auf einer möglichen Verbindung zwischen kreativer Leistung und Netzwerkposition. Hierzu werden Befragungsdaten von 1.932 Erfindern und deren 15.168 Patenten analysiert. Es erweist sich, dass bestimmte Persönlichkeitsdimensionen einen Effekt auf die Leistung von Erfindern haben, jedoch nicht auf ihre Position im Erfindernetzwerk. Außerdem zeigt die Analyse reziproke, positive kausale Zusammenhänge zwischen der Leistung von Erfindern und ihrer Netzwerkposition.
