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...

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 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 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...

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...
