Generally speaking, a lottery is any competition that involves paying a fee and winning prizes based on a process that depends solely on chance. It may be as simple as purchasing a ticket and hoping to win the top prize, or it could involve multiple stages of competition with increasing levels of skill required. However, it is important to note that lottery purchases cannot be explained by decision models based on expected value maximization.

The casting of lots for ownership and other rights has a long history, and several instances are recorded in the Bible. In the seventeenth century, lottery games became a popular form of raising funds for a wide range of public usages in the Netherlands. These lotteries were hailed as a painless form of taxation, with players voluntarily spending their money to benefit the public good.

In the United States, state governments have been granted exclusive rights to organize lotteries. As of August 2004, forty-one states and the District of Columbia operate lotteries. Most of the profits are used to fund state programs. In addition, there are several private lotteries that raise funds for a variety of causes.

The popularity of lottery games seems to have a direct correlation with a state’s perceived fiscal health, and has been cited as an effective way to raise revenue without raising taxes. Nonetheless, studies have found that state-run lotteries are still popular even in periods of fiscal prosperity. Clotfelter and Cook report that it is likely that this popularity is due to the fact that lottery proceeds are viewed as an alternative to more direct taxes.
