1. Assignment:
1. Figure 12-9 on page 272 displays real investment spending as
a percentage of global real GDP since the mid-1990s for
developed versus emerging nations. The figure shows that in
recent years, decreases in planned investment expenditures as a
percentage of global real GDP have occurred in highly
developed countries. In contrast, planned investment spending
as a percentage of global real GDP has been rising for nations
with emerging economies.
Global real GDP has increased every year except for a brief dip
during 2009. Consequently, planned real investment has risen in
all nations in most years. What Figure 4 depicts, therefore, is a
shift toward relatively greater increases in planned investment
in emerging nations compared with developed countries.
Within any nation’s economy, variations in planned real
investment spending operate through the multiplier to bring
about changes in equilibrium real GDP. Thus, a country that
experiences a larger upward shift in its planned investment
function than another nation will, if both countries’ multipliers
have close to the same values, observe a greater increase in its
equilibrium real GDP
This relatively larger increase in investment spending helps to
explain why countries such as China, India, South Korea, and
Singapore are emerging from a status of less developed toward
eventual classification among developed nations. Relatively
higher planned real investment expenditures in these nations
are, through multiplier effects, boosting real GDP per year .
Thus, flows of real GDP are expanding faster in these emerging-
economy countries than in developed ones.

2. a. If interest rates, or opportunity costs of investment, happened
to be the same in both developed countries and emerging
economy nations, what could account for faster upward shifts in
the latter group’s planned investment functions?
b. Are stocks of productive capital currently growing at a faster
pace in developed countries or in emerging-economy nations?
Explain.

Paying off State Debts instead of Boosting Expenditures
Figure 13-7 on page 292 of your textbook displays two sets of
data. One is the cumulative quantity of grants of discretionary
funds transmitted from the federal government to state
governments since late 2008. The other is the net amount of
borrowing by state governments.
As grants of federal funds to state governments accumulated
after 2008, the net borrowing of state governments declined.
Many state governments were heavily in debt at the end of
2008, with borrowings in excess of $160 billion. For these
states, the receipt of discretionary federal grants beginning in
2009 was a godsend, because it allowed them to start paying off

3. a number of existing debts.
Debt Repayments are not Immediate Flows of Spending
The funds intended by the federal government to enter the
nation’s flow of income and expenditures did not reach that
flow. States sent them to creditors.
Rather than direct the federal funds to additional spending,
therefore, the state governments used the bulk of ARRA federal
grants to pay off part of debts generated by spending projects
completed in prior years. Most estimates indicate that of the
federal “stimulus” funds given to state governments, less than 5
percent were directed toward new spending within the nation’s
flow of income and expenditures. Thus, a 95 percent direct
fiscal offset resulted. Instead of providing an immediate boost
in state infrastructure spending on roads, bridges, and the like,
nearly all of the federal funds transmitted to state governments
for spending instead were saved.
a. Why might federal spending on roads, waterways, or national
security be less subject to direct expenditure offsets than
spending on health care or education?
b. What might account for the fact that estimates of effect time
lags for fiscal policy often differ considerably across different
types of government expenditures?

3. The U.S. government is in the midst of spending more than
$1 billion on seven buildings containing more than 100,000
square feet of space to be used for study of infectious diseases.
Prior to the government’s decision to construct these buildings,
a few universities had been planning to build essentially the
same facilities using privately obtained funds. After
construction on the government buildings began, however, the
universities dropped their plans. Evaluate whether the
government’s $1 billion expenditure is actually likely to push
U.S. real GDP above the level it would have reached in the
absence of the government’s construction spree.

The Share of Tax Revenue Going To Discretionary Spending
Figure 14-6 on page 312 of your textbook shows the share of
total federal spending on entitlements has increased during the
past 20 years. How has this trend affected the government’s
ability to fund its discretionary spending?
Figure 14-7 on page 314 of your textbook displays the
percentage of tax revenues available to apply toward
discretionary spending—that is, after paying for entitlement
expenditures—since the early 1990s. During the late 1990s, this
percentage rose above 100 percent, meaning that the federal
government officially operated with surpluses and paid down
some of its outstanding debts.
After the late 1990s, however, the percentage of tax revenues
available to cover discretionary spending after paying
entitlements steadily declined. Since the late 2000s, this

5. percentage has dropped substantially.
Indeed, during periods in which the percentage of tax revenues
available to allocate to discretionary spending has been zero or
negative, the federal government’s tax revenues have been
insufficient to pay for any of its discretionary spending. During
these intervals, all discretionary spending has been financed
with borrowed funds.
Borrowing in Part to Cover Entitlement Spending
When the share of federal tax revenues allocated to
discretionary spending is below zero, the government borrows
more than the amount of its discretionary spending. During
these intervals, the government borrows funds to help pay some
of its non-controllable expenditures on entitlements as well as
to cover its discretionary spending.
a. What would be true of entitlement spending if the percentage
of taxes allocated to discretionary spending rose to 100 percent
and the federal budget was balanced? (Hint: Under a balanced
budget, tax revenues equal the sum of discretionary and
nondiscretionary expenditures.)
b. How would entitlement spending be funded if tax revenues
just covered discretionary spending and there was a government
budget deficit?
