Is the Lottery a Public Good?

Lottery is an activity in which people have the chance to win a prize based on the drawing of lots. The term can refer to a specific lottery, such as the National Lottery in the United Kingdom, or it can refer to any event where prizes are awarded by drawing lots. In the latter sense, it can be used to describe a range of activities, from the awarding of military conscription quotas to commercial promotions in which property is given away by drawing lots.

The practice of making decisions and determining fates by the casting of lots has a long history, including several instances in the Bible, where the Lord instructed Moses to take a census of Israel and divide land by lot, and Roman emperors gave away slaves and properties through this method. However, the use of lotteries to raise money for material gain is comparatively recent: public lotteries first appeared in the Low Countries in the 15th century to finance town fortifications and to aid the poor.

State-sponsored lotteries have become a major source of revenue for state governments, with their growth in the last two decades prompting expansion into new games such as video poker and keno as well as more aggressive marketing campaigns. Nevertheless, the growing popularity of these activities raises questions about whether the state should be in the business of encouraging gambling. Lotteries may generate substantial revenues for a state, but they do not necessarily produce the same level of social benefits as more traditional forms of government spending, and there are concerns about how such revenues might be used to promote gambling, which could have negative consequences for poor people and problem gamblers.

Those who argue in favor of the legitimacy of state-sponsored lotteries often stress their value as sources of “painless” revenue, with players voluntarily spending money (in exchange for the possibility of winning) for the benefit of the public good. This argument is strengthened by the fact that lottery proceeds have been used to finance such projects as the rebuilding of Faneuil Hall in Boston and a battery of cannons to defend Philadelphia against the British during the American Revolution.

Despite these arguments, there is evidence that the distribution of lottery play is unequal by socioeconomic status. The wealthiest citizens tend to play at a much higher rate than the poor, and participation rates decrease with formal education. In addition, women play less than men and blacks and Hispanics more than whites. Lottery participation also declines with age, although it increases in the over-65 group. These trends raise concern about how lottery funds might be used to promote gambling, and some states have banned the activity. Others have instituted restrictions on advertising to limit its impact. Others have reacted to public opinion by requiring voter approval before a state can sponsor a lottery.
