Career Concerns and Ambiguity Aversion

2010, Economics Letters

Eric Bennett Rasmusen


Why do people have ambiguity aversion, preferring, a gamble with a 50% chance of success to one whose expected probability of success is 50% but where that 50% is an unbiased estimate? The answer modelled here, in the spirit of the career concerns literature, is learning: a risk-averse person does not wish observers to learn whether he is good or bad at estimating probabilities. He therefore prefers a gamble with objective probabilities.
