The paradigm of bounded rationality considers the limited ability of individuals to make consistent and rational choices. Due to the scarcity of research on this phenomenon in information systems, we conducted an experimental study investigating decision-making regarding risk preferences and...

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...

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...

Can one define and test the hypothesis of (un)bounded rationality in stochastic choice tasks without endorsing Bayesianism? Similar to the state specificity of assets, we rely on state-specific goal formation. In a given choice task, the list of state-specific goal levels is optimal if one...

Similar to welfare economics where with(out) interpersonal comparisons one defines unique (set-valued) welfare (Pareto) optima, we present a framework for one-person decision making where with(out) a prior probability distribution individual optimality prescribes usually a unique (set of)...

During the last three decades the ascent of behavioral economics clearly helped to bring down artificial disciplinary boundaries between psychology and economics. Noting that behavioral economics seems still under the spell of the rational choice tradition - and, indirectly, of behaviorism - we...

We study the nature of dominance violations in three minimalist dominance-solvable guessing games, featuring two or three players choosing among two or three strategies. We examine how subjects' reported reasoning translates into their choices and beliefs about others' choices, and how reasoning...

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...
