Many health policy analysts argue that demographic pressures, the infl
ationary nature of fee-for-service payment, and the uncontrollable nat
ure of defined-benefit insurance make Medicare unsustainable in its cu
rrent form. They assert that Medicare can remain fiscally viable in th
e next century only by embracing a voucher system and exposing benefic
iaries to the economic consequences of their medical care decisions. W
e argue here, however, that Medicare need not rely on vouchers or on p
lacing financial incentives on individual beneficiaries to control cos
ts. Instead, we contend that Medicare can control expenditures the way
most other industrial democracies do: through budgetary caps and cent
ralized regulation of provider payments.
