Viele Umfragen deuten auf eine massive Abwanderung des deutschen Mittelstands in die neuen EU-Beitrittsl?nder hin. Inwieweit kann dieser Exodus empirisch untermauert werden? In welchen Aktivit?ten engagieren sich die deutschen mittelst?ndischen Unternehmen in den Beitrittsl?ndern? Welche Chancen und Risiken erwarten sie von der Osterweiterung?  相似文献

A Network-based Approach on Opportunity Recognition   总被引:4,自引:1,他引:4  
This paper argues that individuals differ in terms of their perception of opportunities because of the differences between the networks they are embedded in. We focus on two aspects of individuals embeddedness in networks, that is, (1) individuals belonging to residential areas that are more or less likely to be characterized by network cohesion, and (2) individuals differential access to network contacts based on the level of human capital they hold. Our analyses show that the nature of ones residential area influences the perception of entrepreneurial opportunities. Further, we find a positive effect for education, i.e., people with a higher educational level are more likely to perceive entrepreneurial opportunities compared to those with a lower educational level.  相似文献

Aufwendungen für Forschung und Entwicklung werden im Hinblick auf die internationale Wettbewerbsf?higkeit eines Wirtschafts- und Technologiestandorts als besonders bedeutsam eingesch?tzt. Wie l?sst sich der Zusammenhang zwischen Forschung und wirtschaftlicher Entwicklung empirisch nachweisen? Welchen Rang nimmt Deutschland im internationalen Vergleich der Forschungs- und Innovationsaktivit?ten ein? Welche Handlungsoptionen ergeben sich für die Wirtschaftspolitik?  相似文献

This article seeks to extend research on small to medium-sized enterprises (SMEs) and ambidexterity by investigating contingency factors that influence the relationship between contextual ambidexterity and SME performance. Acknowledging the importance of internal knowledge flows in leveraging ambidexterity, it offers unique insights into how internal and external rivalry conditions influence performance outcomes related to an ambidextrous posture. Using a sample of Canadian-based SMEs, the study shows that the contextual ambidexterity–performance relationship is suppressed at higher levels of internal rivalry and amplified at higher levels of external rivalry. The findings suggest that developing an ambidextrous posture should not be an end by itself, and they point to the need for SMEs to understand how the features of their internal and external environments affect the performance consequences of such posture.  相似文献

Marketing managers commonly employ complex price plans. Surprisingly, limited and conflicting evidence reports how customers perceive and react to complex prices. This study examines perceptions about price complexity and shows that customers tend to prefer simple prices. Two experimental studies show that perceived price complexity negatively affects customer perceptions of price fairness and influences product choice because customers negatively evaluate the transparency of the firm's pricing practices and infer higher total prices. Customers comparing alternate offerings may therefore prefer simple over complex prices, even when the latter are less expensive. Study results suggest limiting price plan variations positively affects customer inferences about transparency and fairness, and thus customer choice.  相似文献

The authors detail an urban economics experiment that is easily run in the classroom. The experiment has a flexible design that allows the instructor to explore how congestion, zoning, public transportation, and taxation levels determine the bid–rent function. Heterogeneous agents in the experiment compete for land use using a simple auction mechanism. Using the data that is collected, a bid–rent function is derived, and the experimental treatment is altered over the course of three sessions to uncover core concepts in urban economics. Moreover, this provides a tangible experience that can be used to help undergraduates relate to urban issues such as the steep rent gradient found around many larger colleges and universities.  相似文献

We consider a robust version of the classic problem of optimal monopoly pricing with incomplete information. In the robust version, the seller faces model uncertainty and only knows that the true demand distribution is in the neighborhood of a given model distribution. We characterize the pricing policies under two distinct decision criteria with multiple priors: (i) maximin utility and (ii) minimax regret. The equilibrium price under either criterion is lower then in the absence of uncertainty. The concern for robustness leads the seller to concede a larger information rent to all buyers with values below the optimal price without uncertainty.  相似文献

At the turn of 20th century social scientists have built up a large stock of cross-sectional data-sets to study social change. However, scholars more and more collect event history data containing the exact timing of events. Comparing the (dis)advantages event history data are to be preferred. However, for research on value change the event history approach is inapplicable, since it is not possible to ask the timing of a value change retrospectively. I will illustrate that value change (i.e. cohort differences) can be studied adequately with cross-sectional data, if information about the historical context is added. For this purpose I test Inglehart's value change thesis.Interestingly, there are also topics in which cross-sectional data-sets are unnecessarily being used. Using research on secularization as an example, I show that the event-history approach can be used to answer the question whether the decreasing number of religious people concerns a cohort-effect. However, whatever data-set is being used, to study cohort differences, one should always give a theoretical answer to the key-question: what exactly makes cohorts different  相似文献
