a recession

In the above figure, point A represents

a recessionary gap.

Suppose that in a particular economy, the multiplier is equal to 5. In terms of aggregate demand and aggregate supply, this value for the multiplier means that after an increase in investment

at each price level, the aggregate demand curve shifts rightward by an amount equal to 5 times the change in investment.

Business cycle turning points are

brought about by changes in autonomous expenditures that are then subject to the multiplier effect.

The intertemporal substitution effect of a change in the price level results from a

change in the price of current goods relative to future goods

Imports

decrease the size of the multiplier because spending on imports does not increase real GDP in the domestic nation.

decrease; increase

If the price level rises, the purchasing power of wealth

decreases

The size of the multiplier

decreases in the long run.

induced expenditure.

The data in the above table indicate that when the price level is 120

inventories rise and the price level falls

The long-run aggregate supply (LAS) curve

is vertical

In the long run, the multiplier

is zero

The multiplier effect exists because a change in autonomous expenditure

leads to changes in income, which generate further spending.

none of the answers provided are correct

The short-run multiplier is equal to 3, real GDP equals potential GDP of $8,000, and the price level is equal to 100. Suppose that government expenditure decreases by $200. The LONG-RUN effect of the decrease in government expenditure changes real GDP by

nothing; that is, in the long run real GDP equals $8,000

point G.

In the above figure, at the point where AD equals SAS

"Dissaving" occurs whenever

saving is negative

A decrease in autonomous consumption will

shift the aggregate expenditure function downward

In the above figure, B is the current long-run aggregate supply curve and E is the current short-run aggregate supply curve. Technological advances mean the long-run aggregate supply curve and the short-run aggregate supply curve

shift to C and F, respectively.

With an increase in the capital stock, the short-run aggregate supply curve

shifts rightward

In a short-run macroeconomic equilibrium, real GDP exceeds potential GDP. If aggregate demand does not change, then the

short-run aggregate supply curve will shift leftward as the money wage rate rises.

In a short-run macroeconomic equilibrium, potential GDP exceeds real GDP. If aggregate demand does not change, then the

short-run aggregate supply curve will shift rightward as the money wage rate falls.

The data in the above table show that when the price level is 120, if aggregate demand does not change then the

short-run aggregate supply curve will shift rightward.

The larger the multiplier, the ________ the AE curve and the ________ the AD curve from an increase in investment.

steeper; larger the shift in

taxes decrease

In the figure above, if income taxes increase,

the AE curve becomes flatter.

When autonomous expenditure decreases,

the AE curve shifts downward.

In the above figure the economy is initially at point A on the aggregate expenditure curve AE0. Suppose firms expect profits to increase and decide to increase investment. As a result

the AE curve shifts upward to a curve such as AE2.

Moving along which curve does the money wage rate and the price level change in the same proportions?

the LAS curve

In the above figure, the inflationary gap when AD2 is the aggregate demand curve equals

the difference between $18.5 trillion and $18.0 trillion.

A monetarist economist believes that

the economy is self-regulating and will normally, though not always, operate at full employment if monetary policy is not erratic.

The aggregate demand curve illustrates that, as the price level rises

the quantity of real GDP demanded decreases

Other things constant, the economy's aggregate demand curve shows that

the quantity of real GDP demanded decreases when the price level rises

The smaller the slope of the AE curve,

the smaller is the value of the multiplier.

Intertemporal substitution means changes in purchases

through time.

The aggregate demand curve slopes downward because of

wealth and substitution effects.
