Are Pension Fund Managers Overconfident?

Empirical studies show that people tend to be overconfident about the precision of their knowledge, leading to miscalibration. Consistent with this, we found that on overage the decision makers of Swiss pension plans provide too narrow confidence intervals when asked to estimate the past return of various assets. Their confidence intervals are also systematically too narrow in their forecast of future returns, in comparison with the historical volatility. They are less miscalibrated, however, than our laymen sample. Individual differences between the participants' degree of overconfidence are large and stable across those two different tasks. In a linear regression model we present evi-dence that miscalibration is linked to individual characteristics. In our sample younger people with an education from university and with more experience in finance or pension plans are less over-confident than older people without such an education and with less experience.
