5. Chapter 14: Deficit Spending and the
Public Debt

6. Learning Objectives:
Explain how federal government budget deficits occur
Define the public debt and understand alternative measures of the public debt
Evaluate circumstances under which the public debt could be a burden to future generations
Discuss why the federal budget deficit might be measured incorrectly
Analyze the macroeconomic effects of government budget deficits
Describe possible ways to reduce the government budget deficit

7. Did You Know That...
The U.S. federal government spends a total of more than $3 billion per day on Social Security, Medicare, and Medicaid.
Each of these guaranteed spending programs is individually nearly as large as the entire discretionary portion of the federal government’s budget.

8. Public Deficits and Debts: Flows versus Stocks
Government Budget Deficit: situation in which the government spends more than it receives in taxes during a given period of time
Is financed by the selling of government securities (bonds)

9. Public Deficits and Debts: Flows versus Stocks (cont'd)
The federal deficit is a flow variable, one defined for a specific period of time, usually one year.
If spending equals receipts, the budget is balanced.
If receipts exceed spending, the government is running a budget surplus.

10. Public Deficits and Debts: Flows versus Stocks (cont'd)
Balanced Budget: situation in which the government’s spending is exactly equal to the total taxes and revenues it collects during a given period of time
Government Budget Surplus: excess of government revenues over government spending during a given period of time

11. Public Deficits and Debts: Flows versus Stocks (cont'd)
Public Debt: total value of all outstanding government securities
A stock variable

12. Government Finance: Spending More than Tax Collections
Since 1940, the U.S. federal government has operated with a budget surplus in 13 years.
In all other years, the shortfall of tax revenues below expenditures has been financed with borrowing.

13. Figure 14-1 Federal Budget Deficits and Surpluses Since 1940

14. Figure 14-2 The Federal Budget Deficit Expressed as a Percentage of GDP

15. Policy Example: Explaining a $109 Billion Deficit Projection Turnaround
Why was the government’s 2005 deficit projection off by $109 billion?
Federal tax revenues turned out to be more than 15% higher in 2005.
Economic growth caused taxable incomes, hence revenues, to be much higher than anticipated.

16. Evaluating the Rising Public Debt
Gross Public Debt: All federal government debt irrespective of who owns it
Net Public Debt: Gross public debt minus all government interagency borrowing

17. Evaluating the Rising Public Debt (cont'd)
Some government bonds are held by government agencies.
In this case, the funds are owed from one branch of the federal government to another.
To arrive at the net public debt, we subtract interagency borrowings from the gross public debt.

18. Evaluating the Rising Public Debt (cont'd)
Tax revenues tend to be stagnant during times of slow economic growth.
Tax revenues grow more quickly when overall growth enhances incomes.
As long as spending exceeds revenues, the budget deficit will persist.

19. Table 14-1 The Federal Deficit, Our Public Debt, and the Interest We Pay on It

20. Figure 14-3 Net U.S. Public Debt as a Percentage of GDP

21. Net U.S. Public Debt as a Percentage of GDP
During World War II, the net public debt grew dramatically.
After the war
It fell until the 1970s
Started rising in the 1980s
Declined once more in the 1990s
And recently has been increasing again

22. Evaluating the Rising Public Debt (cont'd)
The government must pay interest on the public debt outstanding.
The level of these payments depends on the market interest rate.
Interest payments as a percentage of GDP are likely to rise in the future.

23. Evaluating the Rising Public Debt (cont'd)
As more of the public debt is held by foreigners, the amount of interest to be paid outside the United States increases.
Foreign residents, businesses and governments hold nearly 50% of the net public debt.
Thus, we do not owe the debt just to ourselves.

24. Evaluating the Rising Public Debt (cont'd)
If deficits lead to slower growth rates future generations will be poorer.
Both present and future generations will be economically better off if…
Government expenditures are really investments
The rate of return on such public investments exceeds the interest rate paid on the bonds

25. Evaluating the Rising Public Debt (cont'd)
If the economy is already at full employment, then further provision of government goods will crowd out some private goods.
Deficit spending may raise interest rates, which in turn will discourage capital formation in the private sector.

26. Evaluating the Rising Public Debt (cont'd)
Crowding-out may place a burden on future generations.
Increased present consumption may crowd out investment and reduce the growth of capital goods, which could reduce a future generation’s wealth.
Taxes may have to be increased, imposing higher taxes on future generations in order to retire the debt.

27. Evaluating the Rising Public Debt (cont'd)
Paying off the public debt in the future
If the debt becomes larger, each person’s share would increase.
Taxes would be levied, and may not be assessed equally.
A special tax could be levied based on a person’s ability to pay.

28. Evaluating the Rising Public Debt (cont'd)
Our debt to foreign residents
We do not owe all the debt to ourselves.
Future U.S. residents will be taxed to repay principal and interest.
Portions of U.S. incomes will be transferred abroad.

29. Evaluating the Rising Public Debt (cont'd)
If deficits lead to slower growth rates future generations will be poorer.
Both present and future generations will be economically better off if…
Government expenditures are really investments
The rate of return on such public investments exceeds the interest rate paid on the bonds

30. International Example: Where Are Most Treasury Securities Held Abroad?
More than $2 trillion in U.S. Treasury securities of the $5 trillion in net outstanding debt is held outside the United States.
Japan accounts for more than one-third of all foreign holdings of the U.S. net public debt.

31. Figure 14-4 The Distribution of Foreign Holdings of U. S
Figure The Distribution of Foreign Holdings of U.S. Treasury Securities

32. For critical analysis:
International Example: Where Are Most Treasury Securities Held Abroad? (cont'd)
For critical analysis:
Why might the fact that market interest rates in Japan have hovered very close to 0% during the 2000s help explain relatively large holdings of U.S. Treasury securities by residents of that country?

33. Federal Budget Deficits in an Open Economy
Question: Is there a connection between the U.S. trade deficit and the federal government budget deficit?
A trade deficit exists when the value of imports exceeds the value of exports.
Some say it appears that there is a relationship between trade and budget deficits; at least there is a statistical correlation between the two.

34. Figure 14-5 The Related U.S. Deficits
Sources: Economic Report of the President; Economic Indicators, various issues;
author’s estimates.

35. Federal Budget Deficits in an Open Economy (cont'd)
If foreigners are using the dollars they hold to buy U.S. government bonds, then they will have fewer dollars to spend on U.S. exports.
This means that a U.S. budget deficit can contribute to a trade deficit.

36. Growing U. S. Government Deficits: Implications for U. S
Growing U.S. Government Deficits: Implications for U.S. Economic Performance
Which government deficit is the true deficit?
The government may report distorted measures of its own budget.
Government has not adopted a business-like approach to tracking its expenditures and receipts.
Official government “measures” yield lowest possible deficits and highest reported surpluses.

37. Growing U. S. Government Deficits: Implications for U. S
Growing U.S. Government Deficits: Implications for U.S. Economic Performance (cont'd)
An operating budget includes current outlays for on-going expenses, such as salaries and interest payments.
A capital budget, includes expenditures on investment items, such as machines, buildings, roads and dams.

38. Growing U. S. Government Deficits: Implications for U. S
Growing U.S. Government Deficits: Implications for U.S. Economic Performance (cont'd)
Question
How do higher deficits affect the economy in the short run?
Answers:
If the economy is below full-employment, the deficit can close the recessionary gap.
If the economy is already at full-employment, the deficit can create an inflationary gap.

39. Growing U. S. Government Deficits: Implications for U. S
Growing U.S. Government Deficits: Implications for U.S. Economic Performance (cont'd)
In the long run, higher government budget deficits have no effect on equilibrium real GDP.
Ultimately, spending in excess of receipts redistributes a larger share of real GDP to government-provided goods and services.

40. Growing U. S. Government Deficits: Implications for U. S
Growing U.S. Government Deficits: Implications for U.S. Economic Performance (cont'd)
Thus, if the government operates with higher deficits over an extended period:
The ultimate result is a shrinkage in the share of privately produced goods and services
By continually spending more than it collects, the government takes up a larger portion of economic activity.

41. Growing U. S. Government Deficits: Implications for U. S
Growing U.S. Government Deficits: Implications for U.S. Economic Performance (cont'd)
How could the government reduce all its red ink?
Increasing taxes for everyone
Taxing only the rich
Reducing expenditures
Whittling away at entitlements

42. Policy Example: How Rich Taxpayers Avoid Part of a Tax-Rate Increase
Some estimates show increasing the top bracket from 35% to 39.6% would reduce total taxable income by at least 4%.
Such projections show this increase as giving the highest income taxpayers a greater incentive to incorporate and pay lower corporate-profit tax rates.
Thus, raising the income tax rate by 4.6% would result in less than a 4.6% increase in government tax collections – but an increase, not a decrease, as some suggest.

43. Growing U. S. Government Deficits: Implications for U. S
Growing U.S. Government Deficits: Implications for U.S. Economic Performance (cont'd)
In considering how expenditures might be reduced, it is important to look at entitlements, the federal government payments that are legislated obligations and cannot be reduced or eliminated.
What are some of these entitlements?

44. Growing U. S. Government Deficits: Implications for U. S
Growing U.S. Government Deficits: Implications for U.S. Economic Performance (cont'd)
Entitlements: Guaranteed benefits under a government program such as Social Security, Medicare, or Medicaid
Non-controllable Expenditures: Government spending that changes automatically without action by Congress

46. Growing U. S. Government Deficits: Implications for U. S
Growing U.S. Government Deficits: Implications for U.S. Economic Performance (cont'd)
Entitlements are the largest component of the U.S. federal budget.
To make a significant cut in expenditures, entitlement programs would have to be revised.

Question
What are the political costs of reducing entitlement payments for Social Security, Medicare, and Medicaid???

48. Summary of Learning Objectives
Federal government budget deficits
Whenever the flow of government expenditures exceeds the flow of government revenues a budget deficit occurs.
The public debt
Total value of all government bonds outstanding
The federal budget deficit is a flow, whereas accumulated deficits are a stock, called the public debt.

49. Summary of Learning Objectives(cont'd)
How the public debt might prove a burden to future generations
Higher taxes will reduce private consumption.
Crowding out might reduce economic growth.
Why the federal budget deficit might be incorrectly measured
No distinction between capital expenses and operating expenses
Each estimate is based on a set of assumptions.

50. Summary of Learning Objectives (cont'd)
The macroeconomic effects of government budget deficits
Because higher government deficits are caused by increased government spending or tax cuts, they contribute to a short-run rise in total planned expenditures and aggregate demand.
In the long run, increased deficits only redistribute resources from the private sector to the public sector.

51. Summary of Learning Objectives (cont'd)
Possible ways to reduce the government budget deficit:
Increase taxes
Reduce expenditures by revising the terms of entitlement programs
