The paper analyzes factors that influence the adoption of e-learning and gives an example of how to forecast technology adoption based on a post-hoc predictive segmentation using a classification and regression tree (CART). We find strong evidence for the existence of technological...

We use a sample of 18 countries to study what variables have a significant impact on an indi-vidual?s decision to start a new business and classification and regression trees for an accurate interpretation of the data. Our results support existing literature suggesting the existence of strong...

The paper analyzes the adoption of various e-business technologies. Strong empirical evidence is found for the existence of increasing returns to adoption due to indirect network externalities between related technologies. If a company is close to the technological frontier, its probability of...

Im vorliegenden Bericht wird die Frage untersucht, warum die Bevölkerung in einigen Ländern hinsichtlich Unternehmensgründungen aktiver ist als in anderen. So gründen z. B. in den USA jedes Jahr relativ mehr Menschen ein Unternehmen als in Deutschland. Analysiert wird hier der Einfluss von...

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...

Die Investitionsentscheidungen von Unternehmen für E-Business-Technologien werden von verschiedenen Faktoren beeinflusst. Als wichtigster Faktor für die Investition in eine zusätzliche E-Business-Technologie stellt sich die Zahl der im Unternehmen bereits genutzten E-Business-Technologien...

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...

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

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...
