Lottery is a scheme for raising money by selling chances to share in a distribution of prizes. Tickets are purchased for a small amount of money, and the winning ticket is drawn at random from those purchased. Prizes may be cash or goods, but the largest prizes are often awarded for correctly guessing numbers in a sequence of digits. Many state governments organize lotteries. Some also offer national games, and the US has one of the world’s largest markets for lottery tickets.
In general, lottery purchases cannot be accounted for by decision models based on expected value maximization. However, the purchase of a ticket can be explained by utility functions that take into account risk-seeking behavior. In addition, the purchase of a lottery ticket allows some purchasers to experience a thrill and indulge in a fantasy of becoming wealthy.
The earliest known lotteries are from the Low Countries in the 15th century, where they raised funds to repair town fortifications and help the poor. A similar tradition has roots going back centuries, including the Old Testament’s instruction for Moses to take a census of Israel and divide land by lot, as well as the use of lots for giving away property and slaves during Saturnalian feasts.
In the modern context of a booming economy and rising inequality, the popularity of the lottery is not surprising. The promise of instant riches lures people into irrational gambling behavior, despite the fact that odds of winning are very slim and that there is a greater chance of being struck by lightning than becoming a multi-billionaire through a lottery prize.
