True or False. Lenders are helped by unanticipated inflation.
False
True or False? As a percentage of GDP, the total U.S. public debt is the highest such debt among the world's advanced industrial nations.
False
How does the purchasing power of money relate to the price level?
It is inversely related to the price level
True or false: "Unemployment can be caused by a decrease of aggregate demand or a decrease of aggregate supply."
True, but the magnitude of the effect on unemployment depends on the economic situation.
During the recession of 2007-2009, the U.S. federal government's tax collections fell from about $2.6 trillion down to about $2.1 trillion while GDP declined by about 4 percent. Does the U.S. tax system appear to have built-in stabilizers?
Yes
inflation
reduces the purchasing power of the dollar.
The long-run aggregate supply curve is vertical because the economy's potential output is determined by
the availability and productivity of real resources, not by the price level.
The short-run aggregate supply curve is relatively flat to the left of the full-employment output because
there are large amounts of unused capacity and idle human resources
What effects would each of the following have on aggregate demand or aggregate supply, other things equal? A 12 percent increase in nominal wages (with no change in productivity).
Aggregate supply will decrease .
What effects would each of the following have on aggregate demand or aggregate supply, other things equal? A new national tax on producers based on the value added between the costs of the inputs and the revenue received from their output.

Recognition Lag
Even though the United States has an unemployment compensation program that provides income for those out of work, should we still worry about unemployment?
Yes, because the unemployment compensation program merely gives the unemployed enough funds for basic needs. Correct
Match the following descriptions with the correct aggregate supply curve. Long run
output is fixed; a vertical line
In sequential order, the four phases of the business cycle are
peak, recession, trough, and expansion.
Rapid inflation can undermine money's ability to perform its functions. During periods of runaway inflation
people often revert to barter because money fails as a medium of exchange.
A political business cycle is the idea that
politicians are more interested in reelection than in stabilizing the economy.
Government's fiscal policy options for ending severe demand-pull inflation include
reducing government spending, increasing taxes, or both
What type of tax system would have the most built-in stability?
Progressive tax system, because it increases at an increasing rate as incomes rise, thus having more of a dampening effect on rising (or falling) incomes
Label each of the following scenarios as an example of a recognition lag, administrative lag, or operational lag. Politicians recognize a sudden recession, but it takes many months of political deal making before they finally approve a stimulus bill.
Administrative Lag

cost-push
The type of inflation that is more likely to be associated with a negative GDP gap is
cost-push inflation
If there is an increase in the unemployment rate, the size of the labor force
could increase or decrease.
Label each of the following scenarios as either frictional unemployment, structural unemployment, or cyclical unemployment. A recession causes a local factory to lay off 30 workers.

fixed incomes in nominal terms.
Label each of the following scenarios as either frictional unemployment, structural unemployment, or cyclical unemployment. Tim just graduated from college and is looking for a job.

Other things equal, how will each of the following affect the equilibrium price level and equilibrium level of real output in the short run? A decrease in aggregate demand.
The price level does not change, but real output declines
Assume that (a) the price level is flexible upward but not downward and (b) the economy is currently operating at its full-employment output.

The price level does not change, but real output increases.
What "backs" the money supply in the United States?
There is no concrete backing to the money supply in the United States.
The explanation for a downsloping aggregate demand curve differs from the explanation for the downsloping demand curve for a single product because
a downsloping, single-product demand curve assumes constant prices such that changes in income cause a substitution of a now relatively cheaper product for those whose prices have not changed.
The economy is in a recession. A congresswoman suggests increasing spending to stimulate aggregate demand and raising taxes simultaneously to pay for the increased spending. Her suggestion to combine higher government expenditures with higher taxes is:
a mediocre and contradictory combination of tax and expenditure changes
The crowding-out effect is
a reduction in investment spending caused by an increase in interest rates arising from an increase in government spending
Match the following descriptions with the correct aggregate supply curve. Short run
an upsloping curve; output prices are flexible, but input prices are fixed
Which of the following will shift the aggregate supply curve to the right?
business taxes fall; a new networking technology increases productivity all over the economy
The multiplier
causes an initial change in spending to generate an even larger change in the aggregate demand curve.
Expectations of a near-term policy reversal weaken fiscal policy because
consumers may hesitate to increase their spending because they believe that tax rates will rise again

The three basic functions of money are
medium of exchange, unit of account, and store of value
The nominal interest rate
minus the inflation rate is the real interest rate
Some politicians have suggested that the United States enact a constitutional amendment requiring that the federal government balance its budget annually. Such an amendment, if strictly enforced, would force the government to enact a contractionary fiscal policy whenever the economy experienced a severe recession because
net tax revenue falls and transfer payments rise during a recession, so balancing the budget would require lowering transfer payments and raising taxes.
Seasonal variations and long-run trends complicate the measurement of the business cycle because
normal seasonal variations do not signal boom or recession.

the government raises corporate profit taxes; interest rates rise
If the annual interest payments on the U.S. public debt sharply increased as a percentage of GDP, then
the government would have to use tax revenues or go deeper into debt.
The downsloping aggregate demand curve can be explained by
the interest-rate effect, the real-balances effect, and the foreign purchases effect.
The unemployment rate that is consistent with full employment is __________.
the natural rate of unemployment
The unemployment rate is defined as
the number of unemployed persons divided by the labor force. Correct
The business cycle affects output and employment in capital goods industries and consumer durable goods industries more severely than in industries producing consumer nondurables because
these goods last, so that purchases can be postponed.
A positive unemployment rate—more than zero percent—is fully compatible with full employment because at full employment,
unemployment includes frictional unemployment, which is always positive because people are transitioning to new jobs Correct
The shape of the short-run aggregate supply curve is
upsloping, because wages adjust more slowly than the price level.
The length of a complete business cycle
varies greatly in duration and intensity.

Noncheckable savings deposits, money market deposit accounts, small time deposits, and money market mutual fund balances
Label each of the following scenarios as an example of a recognition lag, administrative lag, or operational lag. To fight a recession, Congress has passed a bill to increase infrastructure spending—but the legally required environmental-impact statement for each new project will take at least two years to complete before any building can begin.
Operational Lag
Label each of the following scenarios as an example of a recognition lag, administrative lag, or operational lag. To fight a recession, the president orders federal agencies to get rid of petty regulations that burden private businesses—but the federal agencies begin by spending a year developing a set of regulations on how to remove petty regulations.

People would sell it for its intrinsic value
