Generational accounting is a method of long-term fiscal analysis that has been developed over the past decade by Laurence Kotlikoff, Alan Auerbach, Jagadeesh Gokhale, and associates in this country and around the world. It is used to assess the sustainability of fiscal policy and the fiscal burdens facing past, current, and future generations. For a given set of policy assumptions, it estimates the present value of taxes that the average person of any age today will ever pay and the present value of benefits that he or she will ever receive as transfer payments; the implications of this policy for the net taxes (taxes paid less transfers received) of people born in the future; and the lifetime net tax rates of generations born in specific years in the past and born in the future.
Generational accounts are thus forward looking, based on estimates made far into the future. They are calculated in four steps:
2. The present value of goods and services that the government will purchase in the future is estimated.
3. The present value of future net taxes paid by future generations is calculated as a required amount -- the net taxes that future generations must pay if the government is to pay its bills as determined by steps #1 and #2 and is to service its debt. Since this requirement is a residual, the calculation cannot distinguish among different future generations, all of which are assumed to pay the same average net tax rate.
4. Lifetime net tax rates for all generations are estimated based on the net taxes and lifetime labor incomes of each generation.
Second, they show how much of a change is needed. This amount is sensitive to whether the increase in net tax is paid only by future generations (as the authors almost always assume) or, more realistically, also by everybody who is alive when Congress enacts the policy change. If paid only by future generations, the latest estimate is that the lifetime net tax rate would have to increase by 72 percent (from 29 percent to 49 percent). If paid both by future generations and by everybody who is alive when taxes are raised, the income tax at all levels of government would have to increase by 20 percent or all taxes by 9 percent. Both the newly born generation and future generations would have a lifetime net tax rate of 32 percent.
These increases are much smaller than calculated a few years ago, such as in early 1994, when the lifetime net tax rate of future generations was estimated as 82 percent instead of 49 percent (assuming the increase was paid only by future generations). These increases would be still smaller if the estimates were updated for the legislation enacted last summer and the recently improved budget outlook.
Third, generational accounts can be used to assess what alternative fiscal policies can achieve generational balance, which is defined as the government paying all its bills.
Fourth, generational accounts can be used to assess how tax and transfer policy can redistribute income among generations.
The creators of generational accounting have contended that the budget deficit cannot answer these questions and therefore is irrelevant and ought to be replaced by generational accounts. This has not happened.
CBO published a careful, extensive report on generational accounts, Who Pays and When?, over two years ago. After evaluating its methods, contributions, and limitations, CBO concluded that "despite the valuable insights generational accounts afford, they should not become part of the regular budget outlook. They lie in the realm of analysis, not accounting. Therefore, CBO believes that the accounts should remain as a tool to analyze policy from a conceptual perspective, rather than serve as an official statement."
