Experiments have revealed that humans often suffer from overconfidence in the accuracy of their information, or ‘miscalibration’. This column uses data from surveys of CFOs to assess their ability to make financial predictions. The results suggest not only that CFOs are miscalibrated, but also that firms with miscalibrated executives appear to be more aggressive in their corporate policies. In other words, the overconfidence of the executive shows up in the company’s policies.

Regret can shape preferences and thus is an important part of the decision-making process. This column presents new findings on the theoretical and behavioural implications of regret. Anticipated regret can act like a surrogate for risk aversion and could deter investment. However, once people have invested, they become attached to their investment. This commitment is higher with better past performance.
