HW Chap 12

Refer to the diagrams, in which AD1 and AS1 are the "before" curves and AD2 and AS2 are the "after" curves. Other things equal, a decline in net exports caused by a change in incomes abroad is depicted by

A

The real-balances effect on aggregate demand suggests that a

lower price level will increase the real value of many financial assets and therefore cause an increase in spending.

Refer to the diagrams, in which AD1 and AS1 are the "before" curves and AD2 and AS2 are the "after" curves. A recession is depicted by

A and B

Refer to the diagrams, in which AD1 and AS1 are the "before" curves and AD2 and AS2 are the "after" curves. Other things equal, inflation is absent in

A and C

In which of the following sets of circumstances can we confidently expect inflation?

Aggregate supply decreases and aggregate demand increases.

Which of the diagrams for the U.S. economy best portrays the effects of an increase in foreign spending on U.S. products?

C

Deflation refers to a situation where

Price level falls, and could be caused by a shift of AD to the left

Refer to the graph. When output increases from Q1 and the price level decreases from P1, this change will

be caused by a shift in the aggregate supply curve from AS1 to AS3

A change in which one of the following factors would shift the aggregate supply curve?

government regulation

An increase in expected future income will:

increase aggregate demand

Which of the following is not a reason why the stimulus package that the government implemented during the Great Recession of 2007-09 did not have as strong an impact on GDP and unemployment as expected?

The stimulus package caused prices to fall in many sectors.

An increase in aggregate demand is most likely to be caused by which of the following?

a decrease in the tax rates on household income

Government actions that were taken in order to stimulate the economy during the Great Recession of 2007-09 included the following, except

a sharp increase in the natural rate of unemployment.

If the dollar appreciates in value relative to foreign currencies,

aggregate demand decreases because net exports decrease.

Refer to the diagram. If the aggregate supply curve shifted from AS0 to AS1 and the aggregate demand curve remains at AD0, we could say that

aggregate supply has decreased, equilibrium output has decreased, and the price level has increased.

Which of the following would not shift the aggregate supply curve?

an increase in the price level

The real-balance effect pertains to the effect of

Price-changes on aggregate demand, while the wealth effect refers to the impact of changes in wealth on aggregate demand

Refer to the figure. If the aggregate demand curve shifts from AD2 to AD1, the multiplier effect on real GDP will be a decrease from

Q2 to Q4

Other things equal, an improvement in productivity will

shift the aggregate supply curve to the right.

The aggregate supply curve (short run)

slopes upward and to the right.

Suppose that nominal wages fall and productivity rises in a particular economy. Other things equal, the aggregate

supply curve will shift right

An economy is employing 2 units of capital, 5 units of raw materials, and 8 units of labor to produce its total output of 640 units. Each unit of capital costs $10; each unit of raw materials, $4; and each unit of labor, $3. If the per-unit price of raw materials rises from $4 to $8 and all else remains constant, the aggregate

supply curve would shift to the left

Suppose that an economy produces 2,400 units of output, employing 60 units of input, and the price of the input is $30 per unit. If productivity increased such that 3,000 units are now produced with the quantity of inputs still equal to 60, then per-unit production costs would

decrease and aggregate supply would increase.

The interest rate effect on aggregate demand indicates that a(n)

decrease in the price level will decrease the demand for money, decrease interest rates, and increase consumption and investment spending.
