We enrich the choice task of responders in ultimatum games by allowing them to independently decide whether to collect what is offered to them and whether to destroy what the proposer demanded. Such a multidimensional response format intends to cast further light on the motives guiding responder...

We report the results of an original experiment that was designed to test the strength and robustness of the attraction effect. Rather than the usual simple tests for this effect, we consider a conceptually simple consumer purchasing task where alternatives are however difficult to evaluate. For...

In this paper, we analyse the implications of labour market integration in a two-region model with local human capital externalities and congestion effects. We show that integration can be a double-edged sword. Integration and the ensuing agglomeration of skilled labour can reduce "real" income...

We investigate experimentally whether collective choice matters for individual attitudes to ambiguity. We consider a two-urn Ellsberg experiment: one urn offers a 45% chance of winning a fixed monetary prize, the other an ambiguous chance. Participants choose either individually or in groups of...

In the hybrid game, one proposer confronts two responders with veto power: one responder can condition his decisions on his own offer but the other cannot. We vary what the informed responder knows about the offers as well as the uninformed responderś conflict payoff. Neither variation affects...

This paper analyzes whether firms conducting internal R&D and acquiring external high-tech equipment experience a complementarity effect. For German CIS data we conduct a complete set of indirect and direct complementarity tests refining the analysis by looking at various types of innovations...

We investigate the role of industry and region-specific conditions for the survival of new businesses in innovative and in other manufacturing industries. The data comprises all German manufacturing start-ups of the 1992 to 2005 period. In contrast to studies for some other countries, we find...

While previous studies highlight the importance of the manufacturing sector in the economy, we argue that rather backbone services play a key role for economic growth. We perform an Input-Output analysis to determine the linkages between backbone services and manufacturing in South Africa. We...

We report on an experiment designed to explore whether a written expression of disapproval affects future levels of cooperation. In between two identical public goods games, participants play a mini dictator game that, depending on the treatment, either gives or does not give the recipient the...

We use the historical self-employment rate as an indicator of a regional culture of entrepreneurship and link this measure to economic growth in recent periods. The results indicate that German regions with a high level of entrepreneurship in the mid- 1920s have higher start-up rates about 80...
