Is a Lottery a Wise Financial Decision?

A lottery is a game in which people buy numbered tickets for a chance to win a prize. The prize may be money or goods. Lotteries are sometimes used to raise funds for public purposes, such as building roads or schools. People may also play for fun, or in the hope of becoming rich. People spend billions of dollars on lottery tickets each year. But is it a wise financial decision?

A key element of any lottery is the procedure by which winners are selected. Tickets are thoroughly mixed, either mechanically (shaken or tossed) or by computer (as shown in the illustration). Then each ticket is selected according to a randomizing rule. The result is that some number of the tickets will be chosen as winners—and only those tickets. Lottery laws typically specify the rules governing the selection of winners and the amount of the prizes. The costs of organizing and promoting the lottery, and a percentage of the prizes, must be deducted from the pool, leaving the remaining sum available for the winning tickets.

Historically, governments have been reluctant to endorse lotteries for moral reasons. But in the 1960s, advocates of legalized gambling began to argue that governments could not ethically refuse to profit from something that people were going to do anyway. This logic, Cohen writes, gave the go-ahead to many state lotteries, and it dispelled longstanding ethical objections to gambling.

Lotteries can be very profitable, as the prizes they offer are very attractive to potential bettors. Moreover, they provide an alternative source of revenue to taxes. In fact, in early America, lotteries played a major role in funding public projects, including canals, roads, churches, schools, colleges, and even the Continental Congress’s attempt to raise money for the Revolutionary War.

The purchase of lottery tickets cannot be accounted for by decision models based on expected value maximization, since the odds of winning are much lower than the cost of purchasing a ticket. However, more general utility functions defined on things other than lottery outcomes can account for this risk-seeking behavior.

Lotteries have long been a popular form of entertainment. They were common in the Roman Empire—Nero was a big fan—and are attested to in the Bible, where the casting of lots is used for everything from dividing land to deciding who gets Jesus’s clothes after his Crucifixion. In modern times, lotteries have become a very popular form of entertainment and an important way to raise money for public projects. However, they should be considered a form of gambling and not an investment. In addition to the high risk, there is no guarantee that you will win. If you do win, be sure to consider taking a lump sum payment rather than annuity payments. This will give you more control over the cash and enable you to invest it in higher-return assets. In addition, a lump sum is taxed at a lower rate. So, be sure to consult your tax advisor before choosing whether or not to participate in the lottery.
