Our study shows that the technological development of a firm can be subject to an endogenous acceleration mechanism. The more advanced a firm is in using a particular set of technologies, the more likely will it adopt additional, related technologies. This acceleration mechanism implies that...

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...

Tree-based methods have become one of the most flexible, intuitive, and powerful data analytic tools for exploring complex data structures. The applicationsof these methods are far reaching. They include financial firms (credit cards: Altman, 2002; Frydman et al., 2002, and investments: Pace, 1995;...

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...

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...

We formally represent the effects of prior gains and losses in a simple dynamic preference calculus based on prospect theorys value function and thoughts adapted from aspiration level theories. We investigate our predictions in questionnaire experiments. Since we document a strong effect of...
