Money to burn

SLOWLY but surely the cost of America’s public-sector pension promises is becoming clear. Last year the best estimate of the shortfall was more than $4 trillion. To deal with its deficit, a giant Californian pension fund, CalPERS, recently announced plans that will increase contributions by employers (in effect, taxpayers) by up to a half, starting in 2015-16.

Final-salary pension costs have risen for decades because workers are living longer and the retirement age has barely budged. The bill was disguised in the 1980s and 1990s by good asset returns. But dismal equity markets have since forced many private providers to close final-salary schemes to new members and switch to less lavish defined-contribution plans.
