The Effect of Communication Media on Cooperation

Abstract. We examine how communication affects cooperation with the help of seven standard public goods experiments that only differ with respect to the medium of pre‐play communication. Our treatments include bidirectional and unidirectional communication via (mostly electronic) auditory and/or visual channels. The results suggest that successful cooperation is attributable to the opportunity of ‘coordinating’ behavior in the communication phase. Furthermore, both the level and the stability of cooperation significantly interact with the communication medium, even though the content of communication is remarkably similar across the communication treatments.     

Experiments in Environmental Economics and Some Close Relatives

Abstract.  It is not only the great number of papers written on environment economics that make it worth dealing with this special branch of experimental research, but the environmental problem in all its facets seems to serve as a catalyst for identifying some methodological problems of the experimental method. For this reason, we will not only try to give an overview of recent experiments in environmental economics but also add some thoughts on the methodological implications of this work. We identify three direct connecting factors for the experimental method and environmental economics. First, social dilemmas are, in many cases, at the core of environmental problems. Experiments are able to test theoretical hypotheses for individual behavior in such social dilemma situations. The second connecting factor comes from the field of applied experimental work and can be characterized as the testbedding of institutional arrangements for the solution of environmental problems. The last direct application of experimental methods to environmental economics concerns the individual evaluation of environmental resources.     

Old flames never die – the role of binding social ties for corporate entrepreneurship in family firms

This paper investigates the role of social ties and family embeddedness for corporate entrepreneurship in family firms. Family firms are mostly characterized by close and often inseparable ties between the dominant family coalition and the firm and offer specific resources within a context of both rational as well as non-rational factors that influence entrepreneurial strategies. We empirically test (n =?181) the relationship between binding social ties and innovation, strategic renewal, and corporate venturing. Our findings indicate a strong significance for networks and close and stable relationships both to inside the firm and the outside in decision making for corporate venturing and innovation. In contrast, the results for strategic renewal show no relevance of strong social ties. We link up with the debate on the role of owners as an important stakeholder group.

     

AN ALTERNATIVE APPROACH TO EXPLAINING BARGAINING BEHAVIOUR IN SIMPLE SEQUENTIAL GAMES

Abstract.  For simple sequential games, the payoff structure has certain bargaining power implication. Intuitively, certain actions may have the effect of the carrot and the stick as sanctioning means. Fair outcomes can be alternatively viewed as the consequence of their presence. Experimental data on various games are used to test the hypothesis of carrot and stick behaviour. We show that our stick and carrot heuristic neatly captures puzzling phenomena in a wide class of simple sequential games. The results support the view that punishing subjects are not worse off than myopic pay-off maximizers as long as subjects are involved in a repeated strangers scheme.     

The Hot Versus Cold Effect in a Simple Bargaining Experiment

In this paper, the strategy method's impact on behavior in sequential bargaining games is investigated. Besides the decision procedure (hot versus cold), we varied the second mover punishment costs (high versus low). Significant impacts of both treatment variables were observed. For example, second movers punished significantly more often in the hot version of the low cost game. Furthermore, first mover behavior was significantly different in the hot and cold versions of both games. In the hot games, first mover behavior suggests an expectation of decreased rewards and/or punishments from second movers. We observed, however, no decrease in reward and an increase in punishment. The hot cold variable only informs first movers that the decision procedure used by second movers has changed. Therefore, first mover behavior must be shaped by their perceived assessment concerning how second movers make decisions. We argue that first mover behavior can be explained by the interaction of two well-known psychological effects: the consensus and positive self-image effects.     

The subjective well-being of workfare participants: insights from a day reconstruction survey

In this article, we shed more light on the subjective well-being of workfare participants and compare it to the well-being of unemployed and employed workers. We use data from a self-conducted survey among participants in workfare schemes in Germany. We examine two subdimensions of subjective well-being – life satisfaction and emotional well-being – separately to obtain a more comprehensive view of the subjective well-being of workfare participants. Our results show that the life satisfaction of people in this group is between that of employed and unemployed people. In contrast, their emotional well-being is the highest of these three groups.
