Sorting Out the Annuity Puzzle

Annuities, usually thought of as deadly dull, have been hot in the press lately – the topic of an early June New York Times piece by economist Richard Thaler and the lead article of the June 18 Barron's.  Both confront the "the annuity puzzle," which can be succinctly stated as, "Why do so few people buy annuities?" Economic theory would predict robust demand for this financial product, especially as the workforce ages, but the reality is quite the reverse.

Economists have wrestled with the annuity puzzle for at least 45 years, beginning with Menahem Yaari who demonstrated that it is rational for people to turn their wealth into guaranteed lifetime income — that is, annuitize. Ever since, economists have tried to reconcile Yaari's sensible analysis with the real-world lack of annuitization by developing more nuanced models of rational behavior. These efforts have produced an abundance of equations but not much insight. More recently, the newer field of behavioral economics has tackled the puzzle by applying concepts like loss aversion and status quo bias. These efforts have proved more fruitful.

But something is still missing. All of this economic analysis has focused on buyer behavior, treating individuals who buy or don't buy annuities the same as consumers who buy televisions or automobiles. But unlike as with most consumer goods, the initiative to purchase most financial products, including annuities, comes from financial salespeople – insurance agents, stockbrokers, bank representatives and other advisors. Most financial purchases involve what economists refer to as information asymmetry – in which the seller possesses an information advantage over the buyer. To better understand the annuity puzzle, we need to study the sellers.
