We are currently investigating genetic influences on self-employment in an international research consortium using genome-wide association studies (GWAS). By meta-analysing results from numerous independent samples we address identification issues arising from multiple testing. To our knowledge,...

This paper studies the adoption times of various e-business technologies in a large sample of firms from 10 different industry sectors and 25 European countries between 1994 and 2002. The results show that the probability of adoption increases with the number of previously adopted e-business...

Analyzing a cross-country panel of 16 OECD countries from 2002 to 2005, we find that higher unemployment benefits crowd out nascent entrepreneurial activity. Our results hold regardless of entrepreneurial motivation (necessity or opportunity) and entrepreneurial type (imitative or innovative).

We study a unique sample of 1,547 nascent entrepreneurs in Germany and analyze which factors are associated with their start-up satisfaction. Our results identify a group of nascent entrepreneurs that “cannot get satisfaction†with their start-up because they did not choose to become...

This paper studies the diffusion of multiple related technologies among firms. The results suggest an endogenous acceleration mechanism for 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 analyze the effect of peer influence on the diffusion of an innovative network good. We argue that the adopters of a network good have an incentive to convince others to purchase the same product because their utility depends on the number of other users. This peer-effect influences...

The study provides theoretical insights and empirical evidence on the emergence of different types and degrees of entrepreneurial innovativeness. The results suggest that entrepreneurial innovativeness depends both on individual factors and on the environment in which the individual lives. In...

This study examines the influence of joy on absolute and relative overconfidence in a decision experiment with monetary incentives. We used a general knowledge task of medium difficulty to measure overconfidence. Participants’ moods were measured at the beginning of the experiment using...

We investigate whether risk seeking or non-concave utility functions can help to explain the cross-sectional pattern of stock returns. For this purpose, we analyze the stochastic dominance efficiency classification of the value-weighted market portfolio relative to benchmark portfolios based on...

Most agent-based simulation models of financial markets are discrete-time in nature. In this paper, we investigate to what degree such models are extensible to continuous-time, asynchronous modelling of financial markets. We study the behaviour of a learning market maker in a market with...
