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,...

In New Keynesian as well as in Post Keynesian macroeconomic models, money supply is assumed to be endogenous. The reasons for the endogeneity and the role of the financial sector in the supply process, however, are seen very different. In this paper we explicitly derive the behaviour of the...

Es besteht empirische Evidenz, dass reale Spieler weitaus mehr Vertrauen und Vertrauenswürdigkeit entwickeln als es nach den Voraussagen der klassischen Spieltheorie rational ist. Das Papier skizziert den Indirekt Evolutionären Ansatz zur Erklärung der Entstehung von Vertrauen nach Güth und...

Global environmental protection is characterized as a public good. In contrast to the national level where the state is able to regulate external effects, there is a lack of supranational institutions which have enough power to force countries to reduce pollution levels. In spite of the...

The paper investigates the optimal regulation of a (software) firm which acts as a natural monopolist, who also offers a complementary good (IT services) on a competitive market. It is shown that a first-best-regulation accompanyied with an optimal taxation schedule in order to compensate the...

The paper extends the Nash equilibrium concept to account for arbitrary behavioral heuristics. Players are allowed not only to choose strategies, but also to select behavioral rules how to choose strategies. It is argued that behavioral profiles are in equilibrium if no player can benefit from...

In a static symmetric duopoly the set of behavioral rules is extended to different types of markup pricing. Using an equilibrium concept suggested in Pasche (2001), it is shown that dependend on the markup neither pure Cournot nor pure Bertrand behavior is a behavioral equilibrium profile....

Zusammenfassung: Es gibt eine wachsende Literatur zur "verhaltensorientierten" bzw. "psychologischen" Spieltheorie. Die meisten dieser Ansätze beziehen verschiedene Vorstellungen von Fairness, Ungleichheitsaversion oder andere intrinsische Motive in die Nutzenfunktion ein, um empirisch...

Das Papier charakterisiert die spezifischen Eigenschaften des Gutes Software. Als Alternative zur Bereitstellung von Software über Märkte werden die Charakteristika der "freien" Open-Source-Softwareentwicklung dargestellt, bei der die Entwickler auf eine unmittelbare kommerzielle Verwertung...

There is robust experimental evidence that in the ultimatum game real players often prefer a fair allocation which seems to be in contrast to rational decision making. In this paper rational maximizing behavior as well as norm-guided fair behavior are two possible behavioral rules. It is argued...
