In Ancient China, lottery slips were found dating back to around 205 BC. The Chinese used the lottery to fund important government projects, including the construction of the Great Wall of China. In the Roman Empire, the first lotteries were held as entertainment for dinner parties. Emperor Augustus was the first to make the lottery a commercial endeavor, using the profits to repair the city. Today, many nations, including the United States, hold lottery draws to raise money for public projects.
The purchase of a lottery ticket has a higher price than the expected gain, and so lottery tickets should only be purchased if the expected utility is maximized. However, this isn’t a problem, as lottery enthusiasts are often motivated by the fantasy of becoming wealthy and rich. Several utility models can explain lottery purchases, including the generalized expectation-maximizing utility model. This type of model can account for the fact that lottery tickets can be expensive, while the thrill of the jackpot can be very appealing.
Lottery winnings aren’t always paid out as a lump sum. Those who win a lottery can choose between an annuity or a one-time payment. One-time payments are often less than advertised jackpots, due to the time value of money and income tax withholdings. Some jurisdictions require players to pay a percentage of their winnings before they get paid. The same holds true if the lottery is played online.
