Lottery is a game where participants buy tickets for the chance to win a prize based on a random selection of numbers. In a lottery, the prize money can be cash, goods, or services. When there is high demand for something that is limited or scarce, a lottery may be run to make the process fair for everyone. Examples include a lottery for units in a subsidized housing block or kindergarten placements at a reputable public school. The term “lottery” is also used to refer to a general game of chance. For example, the stock market is often described as a lottery because its outcome depends on luck or chance.
People spend upwards of $100 billion on lottery tickets annually in the US. State governments promote these games as a way to raise revenue for a social safety net that would otherwise be very expensive. Yet this message obscures the regressivity of lottery play, and it deceives people about how much they are really spending.
Many people who play the lottery do not understand what they are doing. I have talked to people who have been playing for years, spending $50, $100 a week on tickets. They tell me that they enjoy the entertainment value of buying a ticket. They also get a small amount of utility from the hope that they will win. Ultimately, though, the winnings are much smaller than advertised because of the time value of money and income taxes.
