Many important decisions are made without precise information about the probabilities of the outcomes. In such situations, individual ambiguity attitudes influence decision making. The present study identifies affective states as a transient cause of ambiguity attitudes. We conducted two...

We model entrepreneurship and the emergence of firms as a result of simultaneous bidding for labor services among heterogeneousagents. Unique to our approach is that occupational choices, jobmatching and organizational forms are determined simultaneously, sothat the opportunity costs of...

This paper studies the diffusion of multiple, related technologies among firms. The results suggest an endogenous acceleration mechanism of technology adoption: The more advanced a firm is in using a particular set of technologies, the more likely it is to adopt additional, related technologies....

We develop a new perspective on the boundary of the firm that is consistent with the empirical observation that the share of entrepreneurs first decreases and then increases in the course of economic development. Existing theory based on transaction costs is difficult to relate to these...

We study a unique sample of 1,547 nascent entrepreneurs in Germany and analyze which factors are associated with their self-reported satisfaction regarding their start-up. Our study identifies a new facet of procedural utility and offers new insights about the motivations and goals of nascent...

Across countries, women own significantly fewer businesses than do men. We show that this is due, in large part, to the fact that the propensity to start businesses of women is significantly lower than that of men. The lower propensity of women, in turn, appears to be highly correlated to...

A large literature establishes that cognitive and non-cognitive skills are strongly correlated with educational attainment and professional achievement. Isolating the causal effects of these traits on career outcomes is made difficult by reverse causality and selection issues. We suggest a...

We develop a new perspective on the boundary of the firm that is consistent with the empirical observation that the share of entrepreneurs first decreases and then increases in the course of economic development. Existing theory based on transaction costs is difficult to relate to these...

We develop a polygenic index for individual income and examine random differences in this index with lifetime outcomes in a sample of ~35,000 biological siblings. We find that genetic fortune for higher income causes greater socio-economic status and better health, partly via intervenable...

We study the cyclical pattern of entrepreneurial activity. Results across 22 OECD countries for the period 1972-2007 show that entrepreneurial activity is a leading indicator of the business cycle in a Granger-causality sense. This contradicts existing theoretical hypotheses which predict that...
