Cooperation norms often emerge in situations, where the long term collective benefits help to overcome short run individual interests, for instance in repeated Prisoner´s Dilemma (PD) situations. Often, however, there are different paths to cooperation, benefiting different kinds of actors to...

The European Union´s (EU) Renewable Energy Directive (RED) continues to be the focus of much debate over the validity of biofuel sustainability. The debate is driven in part by ongoing concerns of transparency and regional variations of emissions from feedstock cultivation and processing. In a...

We investigate whether people become more willingly self-employed during boom periods or in recessions and to what extent it is the business cycle or the employment status influencing entry rates into entrepreneurship. Our analysis for Germany reveals that start-up activities are positively...

We develop a model in which novelty and conformity motivate fashion behavior. Fashion cycles occur if conformity is not too high. The duration of fashion cycles depends on individual-specific conformity, novelty, and the number of available styles. The use of individual-specific novelty and...

Based on detailed information about the regional knowledge base, particularly about universities, we find that regional public research and education have a strong positive impact on new business formation in innovative industries but not in industries classified as non-innovative. Measures for...

This paper examines the consequences of introducing a normally distributed effect into a system where the dependent variable is ordered and the explanatory variable is ordered and endogenous. Using simulation techniques we show that a naive bivariate ordered probit estimator which fails to take...

Behavioural economics attracted attention from environmental economists: it should help to understand why people do not respond to environmental policy measures, based on neoclassical assumptions, as predicted by theory. Moreover, understanding motives and driving forces behind pro-social,...

A group of actors, individuals or firms, can engage in collectively providing projects which may be costly or generating revenues and which may benefit some and harm others. Based on requirements of procedural fairness (Güth and Kliemt, 2013), we derive a bidding mechanism determining...

In this paper, I discuss the difference between accommodated evidence (i.e. when evidence is known first and a hypothesis is the proposed to explain and fit the observations) and predicted evidence (i.e., when evidence verifies the prediction of a hypothesis formulated before observing the...
