Fiscal Policy
• Fiscal policy is the manipulation of the federal budget to attain price stability, relatively full employment, and a satisfactory rate of economic growth– To attain these goals, the government must
manipulate its spending and taxes

• There was no such thing as fiscal policy until John Maynard Keynes invented it in the 1930s– He maintained that
• The only way out of the Depression was to boost aggregate demand by increasing government spending
• If we ran a big enough budget deficit, we could jump-start the economy and, in effect, spend our way out of the depression

• It’s important that the aggregate supply of goods and services equals the aggregate demand for goods and services at just the level of spending that will bring about full employment at stable prices

• Equilibrium GDP tells us the level of spending in the economy
• Full-employment GDP tells us the level of spending necessary to get the unemployment rate down to 5 percent (which we have been calling full-employment)
• Fiscal policy is used to push equilibrium GDP toward full-employment GDP

The Deflationary Gap and the Inflationary Gap
• Equilibrium GDP is the level of output at which aggregate demand equals aggregate supply– Aggregate demand is the sum of all
expenditures for goods and services (that is, C + I + G + Xn)
– Aggregate supply is the nation’s total output of final goods and services
– So at equilibrium GDP, everything produced is sold
12-7Copyright 2005 by The McGraw-Hill Companies, Inc. All rights reserved.
• Full-employment GDP is the level of spending necessary to provide full employment of our resources– If our plant and equipment is operating at
between 85 and 90 percent of capacity, that’s considered full employment
– If only 5 percent of our labor force is unemployed, that’s full employment

Equilibrium GDP
When equilibrium GDP is greater than full-employment GDP, there is an inflationary gap. How large is it?

Summary
• Equilibrium GDP is above the full-employment GDP– Spending is too high– Results in an inflationary gap
• To eliminate the inflationary gap, we cut G and/or raise taxes

The Multiplier and Its Applications
12-13
• Any change in spending (C, I, or G) will set off a chain reaction, leading to a multiplied change in GDP
GDP = C + I + G + Xn
How much the multiplied change is depends on the MPC and MPS
Copyright 2005 by The McGraw-Hill Companies, Inc. All rights reserved.
Calculating the Multiplier
• Remember– MPC + MPS = 1, therefore, MPS = 1 - MPC
Multiplier = -----------------------1
1 - MPC
Multiplier = ----------------------1
MPS

Because the multiplier (like C) deals with spending, 1/(1-MPC) is a more appropriate formula)

Applications of the Multiplier
• The Multiplier is used to calculate the effect of changes in C, I, or G on GDP
GDP = 2,500; Multiplier = 3; C rises by 10
What is the new level of GDP
12-20
GDPNew = GDPInitial + (Change in spending X Multiplier)
GDPNew = 2500 + ( 10 x 3)GDPNew = 2500 + ( 30)GDPNew = 2530

Applications of the Multiplier
• The Multiplier is used to calculate the effect of changes in C, I, or G on GDP
GDP = X; Multiplier = 3; C rises by 10
What happens to GDP
12-21
GDPNew = GDPInitial + (Change in spending X Multiplier)
GDPNew = X + ( 10 x 3)GDPNew = X + ( 30)GDP increases by 30

Applications of the Multiplier
• The Multiplier is used to calculate the effect of changes in C, I, or G on GDP
GDP = X; Multiplier = 7; G falls by 5
What happens to GDP
12-22
GDPNew = GDPInitial + (Change in spending X Multiplier)
GDPNew = X + ( -5 x 7)GDPNew = X + ( -35)GDP decreases by 35

The Automatic Stabilizers
• The automatic stabilizers protect us from the extremes of the business cycle– Personal Income and Payroll Taxes
• During recessions, tax receipts decline
• During inflations, tax receipts rise
– Personal Savings• During recessions, saving declines
• During prosperity, saving rises
12-27Copyright 2005 by The McGraw-Hill Companies, Inc. All rights reserved.
The Automatic Stabilizers
• The automatic stabilizers protect us from the extremes of the business cycle– Credit Availability
• Credit availability helps get us through recessions
– Unemployment Compensation• During recessions more people collect
unemployment benefits
12-28Copyright 2005 by The McGraw-Hill Companies, Inc. All rights reserved.
The Automatic Stabilizers
• The automatic stabilizers protect us from the extremes of the business cycle– The Corporate Profits Tax
• During recessions, corporations pay much less corporate income taxes
– Other Transfer Payments• Welfare (or public assistance) payments,
Medicaid payments, and food stamps rise during recessions
12-29Copyright 2005 by The McGraw-Hill Companies, Inc. All rights reserved.
Discretionary Fiscal Policy
• Making the Automatic Stabilizers More Effective– Public Works
• The main fiscal policy to end the Depression was public works
– Transfer Payments• The government could extend the benefit period
for unemployment compensation and increase welfare payments, Social Security, and veterans’ pensions
12-30Copyright 2005 by The McGraw-Hill Companies, Inc. All rights reserved.
Without the automatic stabilizers, real GDP would fluctuate much more widely. But you will note that, while the stabilizers do smooth out the cycle, they do not eliminate it.Copyright 2005 by The McGraw-Hill Companies, Inc. All rights reserved. 12-31
Discretionary Fiscal Policy
• Making the Automatic Stabilizers More Effective– Changes in Tax Rates
• To fight inflation, the government can raise taxes• To fight recession, the government can cut taxes• Corporate incomes taxes can be raised during periods of
inflation and lowered when recessions occur
– Using tax rate changes as a counter cyclical policy tool provides a quick fix, however, temporary tax cuts carried out during recessions should not become permanent
12-32Copyright 2005 by The McGraw-Hill Companies, Inc. All rights reserved.
Discretionary Fiscal Policy
• Making the Automatic Stabilizers More Effective– Changes in Government Spending
• The government increases spending and cuts taxes to fight recessions
• The government decreases spending and raises taxes to fight inflation
• In brief, we fight recessions with budget deficits and inflation with budget surpluses
12-33Copyright 2005 by The McGraw-Hill Companies, Inc. All rights reserved.
Who Makes Fiscal Policy?
• The President and Congress make fiscal policy– This is complicated and can be time
consuming, especially when one political party controls Congress while the president belongs to the other party
– No one seems to be in charge of making fiscal policy
12-34Copyright 2005 by The McGraw-Hill Companies, Inc. All rights reserved.
The Deficit Dilemma
• Deficits, Surpluses, and the Balanced Budget– When government spending is greater than
tax revenue, we have a federal budget deficit• The government borrows to make up the
difference
• Deficits are prescribed to fight recession
12-35Copyright 2005 by The McGraw-Hill Companies, Inc. All rights reserved.
The Deficit Dilemma
• Deficits, Surpluses, and the Balanced Budget– When the budget is in a surplus position, tax
revenue is greater than government spending
• Budget surpluses are prescribed to fight inflation
12-36Copyright 2005 by The McGraw-Hill Companies, Inc. All rights reserved.
The Deficit Dilemma
• Deficits, Surpluses, and the Balanced Budget– We have a balanced budget when
government expenditures are equal to tax revenue
• We’ve never had an exactly balanced budget• We’re dealing with a budget of nearly $4 trillion
in taxes and spending• Perhaps, if the deficit or surplus were less than
$20 billion, we’d call that a balanced budget

The Surplus or Deficit as a Percentage of GDP, Selected Countries , 2003
The Economist, May 24, 2003
Why Are Large Deficits So Bad?
• Large deficits raise interest rates• The federal government has become
increasingly dependent on foreign savers to finance the deficit
• Until, the mid-1990s the deficit sopped up more than half the personal savings in this country, making much less available to large corporate borrowers seeking funds for new plant and equipment
12-40Copyright 2005 by The McGraw-Hill Companies, Inc. All rights reserved.
Must We Balance the Budget Every Year?
• In a word, “no!” – We couldn’t , even if we tried– During recessions, the budget will automatically go
into deficit– Events beyond our control can force the federal
government to spend great sums of money• However, some believe that barring national
emergencies and possibly recessions, the government should be legally bound to balance its budget every year. – During the 1990s, several attempts were made to
pass a constitutional amendment requiring this– None were successful
12-41Copyright 2005 by The McGraw-Hill Companies, Inc. All rights reserved.
The Public Debt
• Differentiating between the Deficit and the Debt– The deficit occurs when federal government
spending is greater than tax revenue– The debt is the cumulative total of all the federal
budget deficits less any surpluses• Suppose that our deficit declined one year from $200
billion to $150 billion• The national debt would still go up by $150 billion• So every year that we have a deficit – even a declining one
– the national debt will go up

National Debt, 1980-2004
Economic Report of the President, 2003
The Public Debt
• Who holds the national debt?– Private American citizens hold a little less than half
– Foreigners hold almost one-third
– The rest is held by banks, other business firms, and U.S. government agencies (mainly the social security trust fund and the Federal Reserve)
• Is the national debt a burden that will have to borne by future generations?– As long as we owe it to ourselves, the answer is no
– If we did owe it mainly to foreigners, and if they wanted it paid off, it could be a great burden
12-44Copyright 2005 by The McGraw-Hill Companies, Inc. All rights reserved.
The Public Debt
• When do we have to pay off the debt?– We don’t. All we have to do is roll it over, or
refinance it, as it falls due
– Each year more than one trillion dollars worth of federal securities fall due
• By selling new ones, the Treasury keeps us going
– In the future, even if we never pay back one penny of the debt, our children and our grandchildren will have to pay hundreds of billions of dollars in interest
• At least to that degree, the public debt will be a burden to future generations
12-45Copyright 2005 by The McGraw-Hill Companies, Inc. All rights reserved.
The Public Debt
• Why not go ahead and just pay off the debt?– Economists predict that following this course would
have catastrophic consequences
– If we tried to pay off the debt too quickly, it might even send us into a deep depression
– When the economy is experiencing high unemployment, we need to run budget deficits
– During prosperity, particularly when inflation is a major problem, we need budget surpluses, paying off the debt
• This is the part we have ignored during the last three decades
