Economic theory has evolved without paying proper attention to behavioral approaches, especially to social, economic, and cognitive psychology. This has recently changed by including behavioral economics courses in many doctoral study programs. Although this new development is most welcome, the...

Economic behavior strives for efficiency. Therefore, also evolving network structures should be a result of such a goal-oriented behavior. Traditionally, networks were assumed to be only temporary phenomena, since the prevailing organizational forms that comply with the efficiency postulate are...

Costly signaling of commitment to a group has been proposed as an explanation for participation in religion and ritual. But if the signal's cost is too small, freeriders will send the signal and behave selflshly later. Effective signaling may then be prohibitively costly. If the average level of...

Institutional settings and the resulting incentive structures are crucial for economic development. The type of entrepreneurial activity and the entrepreneurial effort are especially dependent on underlying incentive structures. We argue that institutions with better incentive structures for...

This paper investigates the impact of implicit institutions on the decision to become an entrepreneur. Implicit institutions are here defined as mindsets that have developed as the result of norms and traditions and we expect they will have an influence on risk attitudes and opportunity...

The aim of this paper is to analyse the effects of knowledge management on the innovation success of firms in Germany. Using a matching procedure on data from the German Innovation Survey of 2003 ("Mannheim Innovation Panel"), we pair firms applying knowledge management with twin firms with...

Using survey data from the International Social Survey Program, we investigate how individual preferences for redistribution and public spending are affected by gender, income and expected future living standard. Applying the concept of the equivalence income, we find that some respondents...

Technological change and gains in efficiency of renewable power generation technologies are to a large extent driven by governmental support. Various policies that can broadly be categorized as technology push, demand pull or systemic constitute a policy mix for renewable energies. Our goal is...

Bubbles are omnipresent in lab experiments with asset markets. But these experiments were (mostly) conducted in environments with only human traders. Today markets are substantially determined by algorithmic traders. Here we use a laboratory experiment to measure human trading behaviour changes...

We conduct an experiment meant to explore the factors driving customers' decisions in a queueing system. Under different time allowance conditions, the experimental subjects are asked to join one of two queues that differ in their length, server speed, and entry fee. We investigate some aspects...
