Costs and Benefits of Lottery

A lottery is an arrangement whereby something that is in limited supply and in high demand is allocated by a process that relies on chance. The process may be used to dish out cash prizes, fill vacancies in a sports team among equally competing players, place students in a school or university, and so on.

Lottery is widely used for public service, and its popularity with the public suggests that it is perceived as a painless way to raise revenue. However, it is important to examine the costs and benefits of this activity.

The most obvious benefit is that people who win the lottery can change their lives dramatically. The winnings they receive can be used to help their families, give them freedom, or just make life a little bit easier. But there are other ways that lottery profits benefit society, too.

In the US, a portion of lottery proceeds is often earmarked for education. This is a noble goal, but the fact is that lottery proceeds are not likely to increase education budgets significantly. The reason is that states are required to run much tighter fiscal ships than the federal government, and lottery money can be used to plug holes elsewhere in the state budget.

It is also possible that the purchase of lottery tickets reflects risk-seeking behavior. This is not necessarily a problem, but it does mean that the purchase of lottery tickets cannot be accounted for by decision models based on expected value maximization. More general models based on utility functions that are defined on things other than lottery outcomes can, however, account for lottery purchases.
