摘要：As illustrated by the famous Ellsberg paradox, many subjects preferto bet on events with known rather than with unknown probabilities,i.e., they are ambiguity averse. In an experiment, we examine subjects'choices when there is an additional source of ambiguity, namely, whenthey do not know how much money they can win. Using a standardindependence assumption, we show that ambiguity averse subjectsshould continue to strictly prefer the urn with known probabilities.In contrast, our results show that many subjects no longer exhibitsuch a strict preference. This should have important ramifications formodeling ambiguity aversion
