Empirical studies show that agents often violate Bayes' rule in updating probability expectations. This paper deals with errors in combining observations with prior knowledge. Such errors neccessarily occur when agents have limited information-processing capacities. It is shown that rational...

The paper presents a simple model of banking behavior where portfolio, liquidity, and liability management determine simultaneously the demand and supply of borrowed reserves on the interbank market. As the central bank is one player in this market due to its refinancing policy, it is able to...

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,...

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...

In standard market theory demand and cost functions have to be known to compute optimal price or quantity responses. In case of risk or uncertainty the decisions depend on expectations, i.e. estimated parameters. Even in case of rational inference these expectations itself are uncertain, at...

Es wird gezeigt, daß unter plausiblen Annahmen im Rahmen der bekannten technologischen Möglichkeiten (``technologisches Regime'') keine dauerhafte Entkopplung des Wachstums vom Umweltverbrauch, d.h. kein nachhaltiges Wachstum möglich ist. Das zentrale Argument ist, daß im Zuge des...

Empirical studies show that decisions deviate from the predictions of expected utility theory and violate the axiomatic foundations. Hence, many generalizations to non-expected utility theory have been developped. But empirically they did not provide an improvement over the standard approach. In...

One of Keynes' core issues in his liquidity preference theory is how fundamental uncertainty affects the propensity to hold money as a liquid asset. The paper critically assesses various formal representations of fundamental uncertainty and provides an argument for a more boundedly rational...
