Much has been writ­ten on the (ir)rationality of pur­chas­ing lot­tery tick­ets (Eliezer Yudkowsky’s view­point is par­tic­u­larly fine), but lit­tle has been said on appli­ca­tions of these biases that could improve the finances of all of those who buy a ticket.

Now behav­ioural econ­o­mists are attempt­ing to boost the his­tor­i­cally poor house­hold sav­ings rate by using our lottery-like opti­mism as an incen­tive to save:

Psy­chol­o­gists have long known that peo­ple tend to over­es­ti­mate the odds of rare events. Apply­ing that behav­ioral insight, finance pro­fes­sor Peter Tufano of Har­vard Busi­ness School has devised a clever pro­gram called “Save to Win.” Launched ear­lier this year for mem­bers of eight credit unions in Michi­gan, it is a cross between a cer­tifi­cate of deposit and a raf­fle ticket. Mem­bers who put $25 or more into a Save to Win one-year CD* are entered into a monthly “sav­ings raf­fle” for prizes up to $400, plus one annual draw­ing for a $100,000 jackpot. […]

In 25 weeks, the pro­gram has attracted about $3.1 mil­lion in new deposits, often from peo­ple who have never been able to set money aside.
