We experimentally explore individual and interactive decision making ina sequential search task and test whether generally accepted principles ofbounded rationality (aspiration formation, satisficing, and aspiration adjustment)adequately explain the observed search behavior. Subjects can, at...

Can one define and test the hypothesis of (un)bounded rationality instochastic 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 cannot...
