Lottery and Bankruptcy:

[P]eople who win large amounts are just as likely to end up bankrupt as people who win small amounts. People who win a large amount, $50,000 to $150,000, have a lower bankruptcy rate immediately after winning but a higher bankruptcy rate a few years later so the 5-year bankruptcy rate for the big winners is no lower than for the small winners. Amazingly, by the time the big winners do go bankrupt their assets and debts are not significantly different from those of the small winners. The big winners who ended up bankrupt could have paid off all of their debts but chose not to.

N.B. the result is not that most lottery winners go bankrupt or that winning money doesn’t help people–the result, as Robin Hanson might say, is that bankruptcy isn’t about money.
