When total tax revenue exceeds total government spending in any year, the government runs a
budget surplus in that year. When the reverse occurs, and total government spending is greater
than total tax revenue, the government runs a budget deficit. The national debt is the total
amount that the federal government owes at a given point in $me. The national debt is the total
value of government bonds held by the public. Deficits add to the national debt, while surpluses
subtract from the national debt. Since the cumula$ve total of the government’s deficits has
been greater than its surpluses, the national debt has grown in recent decades.
Cau$on must be exercised when looking at the size of the deficit and national debt. Just looking
at the raw numbers does not paint an accurate picture of the true size of the figures. As a
consequence, economists usually look at budget related information in relation to a na$on’s
total income—as percentages of GDP.
Given the size of the national debt, should we be concerned about it? Although budget deficits
and growing debt may have nega$ve e”ects on resource allocation and growth, most
economists agree that we are not headed for a debt disaster. This is because the debt never has
to be paid back (the government can always issue new bonds to pay back the old ones) and
because the government has kept its deficit within the range where the debt to GDP ratio
remains stable.
There are three scenarios that should cause concern about the national debt: a national debt
that rises faster than nominal GDP; a debt approaching the national credit limit; and failing to
account for future obligation.
Lastly, a Using the Theory section is included that discusses the fiscal policy response during the
recession of 2008-2009.
In order presented in chapter.
Countercyclical scal policy: A change in government purchases or ne taxes designed to
reverse or prevent a recession or a boom.
Net tax multiplier: The amount by which real GDP changes for each one-dollar change in
net taxes.
Balanced budget multiplier: The multiplier for a change in government purchases that is
matched by an equal change in taxes.
National Debt: The total amount the federal government still owes to the general public
from past borrowing.
Government outlays: Total disbursements by the government for purchases, transfer
payments, and interest on the debt.
Debt ratio: Publicly held national debt as a percentage of GDP.
