The Benefits and Disadvantages of Lotteries


A lottery is a form of gambling in which numbered tickets are sold and prizes are drawn for. It is also the name of a system in which a random number generator chooses winners for other contests or activities. For example, the stock market is often called a lottery because its results depend on chance rather than skill or effort.

The use of lotteries has a long history, dating back to the casting of lots in biblical times and later for municipal repairs in Rome. In modern times, state governments have promoted lotteries as a way to raise money for government programs without imposing burdensome taxes on middle-class and working-class taxpayers. State lotteries are among the fastest growing businesses in the country, generating more than $100 billion annually for their state governments.

Lotteries are extremely popular with the public, but they have several significant problems. The most obvious problem is that they produce very high levels of income for states, with correspondingly low amounts of money for the prizes and expenses of running the games. This is a major source of tension in state budgets. The result is that many people spend a large percentage of their incomes on tickets, but most of them do not win.

Another issue is that lottery revenues are volatile. They tend to grow rapidly at first but then level off or even decline. This volatility makes it difficult for state politicians to justify putting a lot of money into new games when existing revenues are not increasing.

The main argument that has been used to promote lotteries is that they are a source of “painless” revenue, in which players voluntarily spend their money on the state’s behalf. But this argument is flawed for several reasons. First, it assumes that lottery players are all alike in their preferences and tendencies. In reality, lottery players are highly heterogeneous, with a wide range of preferences and tendencies. Second, it overlooks the fact that most state governments require residents to pay a tax, and this is an implicit cost of winning the lottery.

While there are some important differences, the majority of state lotteries share the same fundamental structure. The state legislates a monopoly for itself, establishes a public agency or corporation to run it (as opposed to licensing a private firm in return for a portion of the profits), and begins operations with a modest number of relatively simple games. Eventually, under pressure for additional revenue, the lottery progressively expands its operations.

This expansion is largely driven by the desire to attract more of the middle class and working classes, which is why it has accelerated since the 1970s. However, the overall pattern is still very similar to that of the early postwar period. The difference is that in the immediate post-war period, state governments could afford to expand their social safety nets because lotteries provided them with a substantial and steady stream of income. That arrangement no longer holds true.
