Die Internetnutzung in Deutschland hat in den letzten acht Jahren einen rasanten Anstieg erlebt. Während es im Frühjahr 1995 in Deutschland gerade einmal 250 000 Internetnutzer gab, waren es im Mai 2003 bereits knapp 39 Millionen. Dies bedeutet, dass aktuell etwa 47 % der gesamten Bevölkerung...

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...

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...

In this paper, we propose that researchers might analyze key questions in entrepreneurship as problems of decision making. We believe that this allows for new insights. Experiments are especially suited to empirically test hypotheses derived within such a framework. In this paper, we thus...

We experimentally investigate gender- and occupation-specific differences in market entry behavior and test whether female entrepreneurs are more willing to take strategic risk and engage in competition than other women. To facilitate strategic thinking, we induce asymmetric gain and loss...

This article investigates whether decision makers intuitively optimize close to the normative prediction in entrepreneurial decision situations where their time must be allocated between a wage job and a newly formed venture. We offer an analytical model based on maximizing expected utility, and...

On the basis of a real high stakes insurance experiment with small probabilities of losses, we demonstrate that concern is a more important driver of WTP for insurance than subjective probability estimates when there is ambiguity surrounding the estimate. Concern is still important when...

We analyze the impact of an individual's tendency to worry on willingness to pay (WTP) for a protective measure. We report on the results of a controlled experiment with real objects at stake. Worry was measured with the Worry Domains Questionnaire, an instrument determining an individual's...
