No effect on investment or interest rates All increases in deficits are offset by increased saving (decreased consumption).,Generational Effects of Fiscal Policy,Generational accounting is an accounting system that compares the present value of lifetime tax burden with the benefits

16、of each generation. Is the budget deficit a burden on future generations? Is the deficit in the Social Security fund a burden? Does it matter who owns the bonds that the government sells to finance its deficit?,Generational Effects of Fiscal Policy,Generational Accounting and Present Value Taxes are

17、 paid by people with jobs. Social security benefits are paid to people after they retire. To compare the value of an amount of money at one date (working years) with that at a later date (retirement years), we use the concept of present value.,Generational Effects of Fiscal Policy,The Social Securit

18、y Time Bomb Using generational accounting and present values, economists have found that the federal government is facing a Social Security time bomb! In 2008, the first of the baby boomers will start collecting Social Security pensions and in 2011, they will become eligible for Medicare benefits. B

19、y 2030, all the baby boomers will have retired and, compared to 2006, the population supported by Social Security will have doubled.,Generational Effects of Fiscal Policy,Under the existing Social Security laws, the federal government has an obligation to pay pensions and Medicare benefits on an alr

The multiplier process decreases aggregate demand further.,Stabilizing the Business Cycle,Limitations of Discretionary Fiscal Policy Recognition lag time it takes to figure out that fisc

When real GDP decreases in a recession wages and profits fall, so taxes fall Needs-tested spending rises Budget deficit grows (surplus shrinks),The Budget an
