the level of profit expectations.

Assume that the current equilibrium level of GDP (income and output) is $240 billion and the no inflation, full employment (potential/ ideal) level of GDP is $270 billion. If the MPC = 2/3, what change in aggregate spending is needed to reach full employment without inflation?

Suppose the nominal rate of interest is 7 percent and the real rate is 5 percent. If the expected rate of return on an investment is 6 percent, the firm should

nominal interest rate.
B. undertake the investment because the expected rate of return of 6 percent is greater than the

real rate of interest.

C. not undertake the investment because the expected rate of return of 6 percent is greater than the nominal plus the real interest rate.

D. undertake the investment because the expected rate of return of 6 percent is greater than thedifference between the nominal and real interest rates.

An inflationary gap measures the amount by which

A. the aggregate price level increases.

C. aggregate expenditures/demand exceed aggregate supply at any level of employment.

D. aggregate expenditures/demand exceed aggregate supply at noninflationary full employment.

E. None of the above.

Stock prices have been increasing for the past year. As a result, consumers feel

A. wealthier, and as a result will decrease consumption which will decrease the level of aggregate expenditures and the level of GDP.

B. wealthier, and as a result will increase consumption which will increase the level of aggregate expenditures and the level of GDP.

C. less wealthy, and as a result will decrease consumption which will decrease the level of aggregate expenditures and the level of GDP.

D. less wealthy, and as a result will increase consumption which will increase the level of aggregate expenditures and the level of GDP.

E. None of the above - a change in stock prices does not alter personal consumption spending.

Consumers can actually increase the level of unemployment in the economy (intensify a recessionary gap) by

C. Business confidence and profit expectations can easily change.
D. Current profits provide the necessary funds for future investment.

The multiplier effect means that

A. consumption is typically several times larger than saving.

B. a small increase in consumption will cause a large decrease in investment.

C. a small decrease in investment spending will cause a large increase in the equilibrium

level of income/output (GDP).

D. a small change in investment spending will cause the equilibrium level of income/output (GDP)

to change by a larger amount.

One of the economic costs of unemployment can be measured by

A. the excess of real GDP over nominal GDP.
B. the excess of nominal GDP over real GDP.

C. the amount by which actual GDP exceeds potential GDP.
D. the amount by which potential GDP exceeds actual GDP.

You are given the following information about aggregate demand for an economy: (1)

consumption = $700 billion; (2) investment = $60 billion; (3) government purchases = $100

billion; and (4) net export = $20 billion. If the MPC is 3/4 and the no inflation, full-employment

(ideal) level of GDP for this economy is $800 billion, then what change in aggregate demand

(spending) is needed to reach full employment without inflation?

A. increase aggregate spending by $80 billion

B. decrease aggregate spending by $80 billion

C. decrease aggregate spending by $20 billion

D. increase aggregate spending by $20 billion

Suppose the economy is currently producing $650 billion GDP and the no inflation, full

employment level of production is $610 billion and the MPC = 3/4. If businesses decrease

investment spending by $5 billion this will

A. eliminate the recessionary gap that exists and bring the economy to the no inflation, full

employment level of output.

B. lessen the size of the recessionary gap that exists, but there will still be a recessionary gap.

C. lessen the size of the inflationary gap that exists, but there will still be an inflationary gap.

D. eliminate the inflationary gap that exists and bring the economy to the no inflation, full

employment level of output.

If an increase in aggregate demand results in no increase in real output (production) or employment, we can surmise that

A. the economy is in a deep recession.

B. the MPC equals 1.

C. the price level has fallen.
