Verhaltensökonomik als Gegenprogramm zur Standardökonomik?

Zusammenfassung Die Moderne Verhaltensökonomik ist die natürliche Weiterentwicklung der neoklassischen Standardökonomik der 1980er Jahre. Sie nutzt Erkenntnisse aus benachbarten Sozial- und Verhaltenswissenschaften, um bessere Prognosen zu den Verhaltensänderungen zu erzielen und identifiziert vermeintlich irrelevante Faktoren, deren Berücksichtigung zu besseren Politikmaßnahmen führt. Sie wird in der gesamten Breite der ökonomischen Forschung, in der Wissenschaft und Praxis angewandt. Ihr Erfolg spricht für eine Konvergenz von Verhaltensökonomik und derzeitige Standardökonomik. Schlüsselwörter Verhaltensökonomik, Beschränkte Rationalität, Empirische Wende, Neoklassische Reparatur, Experiment, Pragmatisches Modellieren Abstract Modern behavioral economics is a natural progression of the neoclassical standard economics of the 1980.

Dynamic Repeated Random Dictatorship and Gender Discrimination

To reduce the cognitive experimenter demand effect we embed a dictator game in a more complex decision environment, a dynamic household savings decision problem, thus rendering the dictator decision to share some endowment less salient. We then use this game in a laboratory experiment to investigate gender specific allocation behavior and discrimination. We observe that dictators treat females nicer than males independent of their own gender. Participants are not aware of their discriminating behavior.

Loss Aversion and Learning to Bid

Bidding challenges learning theories. Even with the same bid, experiences vary stochastically: the same choice can result in either a gain or a loss. In such an environment, the question arises of how the nearly universally documented phenomenon of loss aversion affects the adaptive dynamics. We analyse the impact of loss aversion in a simple auction using the experienced-weighted attraction model of learning. Our experimental results suggest that individual learning dynamics are highly heterogeneous and affected by loss aversion to different degrees.

Individual and collective choice and voting in common pool resource problem with heterogeneous actors

In this paper we investigate the effects of heterogeneity in common pool resource (CPR) problems. We examine whether heterogeneity impedes or facilitates coordination on an efficient use of a CPR by proposing and voting on allocation schemes. In a full information design we compare extractions and voting behavior in heterogeneous and homogeneous groups. If the CPR is extracted individually, we find no difference in efficiency between heterogeneous and homogeneous groups. However, when groups can vote on allocation schemes, homogeneous groups are more likely to reach an efficient agreement than heterogeneous groups.
