There’s been an interesting idea floating around for a while that seems to finally be coming to fruition here in the United States: savings account lotteries. You may also hear them called “prize-linked savings accounts”.
I first heard mention of the idea from Freakonomics a few years back. Apparently this idea has been around and in practice for over 50 years now in various other countries and has had a profound impact on increasing the number of people who save. The idea is pretty simple: instead of buying lottery tickets and hoping for a big win, people deposit money into savings accounts or CDs and occasional lottery winners are drawn from the depositors. It offers a sort of no-lose proposition.
