We investigate whether older people correctly perceive their cognitive decline and the potential financial consequences of misperception. First, we show that older people tend to underestimate their cognitive decline. We then show that those experiencing a severe decline but unaware of it are more likely to suffer wealth losses. These losses largely reflect decreases in financial wealth and are mainly experienced by wealthier people who were previously active on the stock market. Our findings support the view that financial losses among older people unaware of their cognitive decline are the result of bad financial decisions, not of rational disinvestment strategies.
That is from a newly published JPE paper by Fabrizio Mazzonna and Franco Peracchi. Here are some less gated versions of the paper.
