A Boon for H&R Block
15.1 Define fiscal policy.
15.2 Explain how fiscal policy affects aggregate demand and how the government can use fiscal policy to stabilize the economy.
15.3 Explain how the government purchases and tax multipliers work.
15.4 Discuss the difficulties that can arise in implementing fiscal policy.
15.5 Define federal budget deficit and federal government debt and explain how the federal budget can serve as an automatic stabilizer.
15.6 Discuss the effects of fiscal policy in the long run.
APPENDIX Apply the multiplier formula.
Learning Objectives
The tax laws have become increasingly complicated. …It is not surprising that millions of Americans have given up filling out their own income tax forms, or have to rely on software such as Intuit’s TurboTax or H&R Block’s TaxCut.

Learning Objective 15.3
The Effect of Changes in Tax Rates
The Government Purchases and Tax Multipliers
A cut in tax rates affects equilibrium real GDP through two channels:
(1) A cut in tax rates increases the disposable income of households, which leads them to increase their consumption spending, and
(2) a cut in tax rates increases the size of the multiplier effect.

Learning Objective 15.3
The Multipliers Work in Both Directions
The Government Purchases and Tax Multipliers
Increases in government purchases and cuts in taxes have a positive multiplier effect on equilibrium real GDP.
Decreases in government purchases and increases in taxes also have a multiplier effect on equilibrium real GDP, only in this case, the effect is negative.

Solved Problem 15-3Fiscal Policy Multipliers
Learning Objective 15.3
Briefly explain whether you agree or disagree with the following statement: “Real GDP is currently $12.2 trillion, and potential real GDP is $12.5 trillion. If Congress and the president would increase government purchases by $300 billion or cut taxes by $300 billion, the economy could be brought to equilibrium at potential GDP.”

Solved Problem 15-5The Effect of Economic Fluctuations on the Budget Deficit
Learning Objective 15.5
The federal government’s budget deficit was $207.8 billion in 1983 and $185.4 billion in 1984. A student comments, “The government must have acted during 1984 to raise taxes or cut spending or both.” Do you agree? Briefly explain.

Although many economists believe that it is a good idea for the federal government to have a balanced budget when the economy is at potential GDP, few economists believe that the federal government should attempt to balance its budget every year.

The Long-Run Effects of Tax Policy
• Individual income tax.
• Corporate income tax.
• Taxes on dividends and capital gains.
We can look briefly at the effects on aggregate supply of cutting each of the following taxes:
In addition to the potential gains from cutting individual taxes, there are also gains from tax simplification.

Most economists would agree that there are supply-side effects to reducing taxes: Decreasing marginal income tax rates will increase the quantity of labor supplied, cutting the corporate income tax will increase investment spending, and so on.
The magnitude of the effects is subject to considerable debate, however.

Appendix
We can define the marginal propensity to import (MPI) as the fraction of an increase in income that is spent on imports. So, our expression for imports is:
Imports = MPI x Y
We can substitute our expressions for exports and imports into the expression we derived earlier for equilibrium real GDP:
(1 )Y C MPC t Y I G Exports MPI Y
Exports MPI Y where the expression represents net exports. We can now find an expression for the government purchases multiplier by using the same method as we did previously:
