A tontine is an investment plan for raising capital, devised in the 17th century and relatively widespread in the 18th and 19th centuries. It combines features of a group annuity and a lottery. Each subscriber pays an agreed sum into the fund, and thereafter receives an annuity. As members die, their shares devolve to the other participants, and so the value of each annuity increases. On the death of the last member, the scheme is wound up.
The investment plan is named after Neapolitan banker Lorenzo de Tonti, who is credited with inventing it in France in 1653, although it has been suggested that he merely modified existing Italian investment schemes. Tonti put his proposal to the French royal government, but after consideration it was rejected by the Parlement de Paris. While the historical financial literature had long credited Tonti as the inventor of the tontine concept, subsequent research discovered that concept was previously proposed by Nicolas Bourey in 1641.
Each investor pays a sum into the tontine. Each investor then receives annual dividends on the capital invested. As each investor dies, his or her share is reallocated among the surviving investors. This process continues until only one investor survives. Each subscriber receives only dividends; the capital is never paid back. In a later variation, the capital devolves upon the last survivor, thus dissolving the trust and usually making the survivor very wealthy.
Louis XIV first made use of tontines in 1689 to fund military operations when he could not otherwise raise the money. The initial subscribers each put in 300 livres and, unlike most later schemes, this one was run honestly; the last survivor, a widow named Charlotte Barbier, who died in 1726 at the age of 96, received 73,000 livres in her last payment. The English government first issued tontines in 1693 to fund a war against France, part of the Nine Years' War.
The Washington Post gives an example:
A simple modern tontine might look like this: At retirement, you and a bunch of other people each chip in $20,000 to buy a ton of mutual funds or stocks or whatever. Every year, the group withdraws a predetermined amount and divides it among the remaining survivors. You might get a bonus one year, for instance, because Frank and Denise died.
Economists have long said that the rational thing to do is to buy an annuity. At retirement age, you could pay an insurance company $100,000 in return for some $5,000-6,000 a year in guaranteed payments until you die. But most people don’t do that. For decades, economists have been trying to figure out why.
James Poterba, an economics professor at MIT who has extensively studied American retirement, says it’s still a mystery why annuities are so unpopular. A number of theories have been advanced — people might like to leave some money for their children, or they might worry about medical expenses late in life. Poterba and his colleagues have also pointed out that Social Security is already like an annuity, promising constant payments for life.
But there’s also some evidence that people just irrationally dislike annuities. As behavioral economist Richard Thaler wrote in the New York Times: “Rather than viewing an annuity as providing insurance in the event that one lives past 85 or 90, most people seem to consider buying an annuity as a gamble, in which one has to live a certain number of years just to break even.”
Here is where tontines come in. If people irrationally fear annuities because they seem like a gamble on one's own life, history suggests that they irrationally loved tontines because they see tontines as a gamble on other people's lives.
