1
Q

What is the interest rate effect?

A

As price level rises so will interest rates, and rising interest rates in turn cause a reduction in certain kinds of consumption and business spending. AD assumes a fixed money supply, so a higher price level will increase the demand for money, and the costs of borrowing will increase

A

Right

30
Q

A decrease in highway construction shifts AD to the?

A

Left

31
Q

Decrease in the value of dollars shifts the AD to the?

A

Right (because exports increase)

32
Q

Canada hating US products shifts AD to the?

A

Left

33
Q

What is happening in the horizontal range of the AS curve?

A

(Recession) real GDP is much less the Qf; high unemployment and unused capacity. As movement to right occurs there’s a gain in real GDP, but no price level change. Production costs usually don’t rise since resources aren’t yet scarce

34
Q

What happens in the vertical range of the AS curve?

A

Economy on PPC; real GDP can’t grow. Firms will bid resources form other firms and resource prices will rise causing some firms to exit the industry. Product prices will rise but real GDP will remain steady

35
Q

What happens in the intermediate range of the AS curve?

A

No simultaneous full-employment full-production in all forms; specific labor/resource shortages; per unit costs rise and firms must get higher prices to retain profit margins

36
Q

What shifts the AS curve?

A

-Changes in input prices
•domestic resource availability (factors of production)
•price of imported resources
•market power (OPEC, powerful labor unions)
-Changes in productivity
•effect of training programs
•technological gains
-Change in legal-institutional environments
•business taxes
•business subsidies
•gov regulation

37
Q

What are causes of downward price level inflexibility?

A

Wage contract, effort, morale, productivity, training investment, minimum wage, menu costs, fear of price wars

38
Q

How does the economy self correct with prices, wages, and interest rates?

A

If there is excess supply of labor (unemployment), workers will reduce their wage demands, causing employers to want to hire more labor and workers to offer less labor for sale, until the surplus is eliminated. Likewise, if there is excess saving, the interest rate will decline, causing people to save less and borrow more, until that surplus is eliminated. In this view, a recovery (from a period of low employment and output) involves a decrease in the price level.

39
Q

What are the 3 reasons that aggregate demand curve is downward sloping?

A
  • interest rate effect
  • wealth effect (real balance effect)
  • foreign purchases effect (foreign trade effect)
40
Q

Why does the investment demand curve have a downward slope?

A

The higher the interest rate, the less investments are made because the cost of borrowing is high

41
Q

If interest rates rise, will the investment demand curve shift to a new location?

A

No, just movement along curve

42
Q

What’s the relationship between the price level and real GDP according to an AD curve?

A

Inverse; the lower the price level, the higher the real GDP

43
Q

What shifts a product demand curve?

A
  • income effect
  • substitution effect
  • diminishing marginal utility
44
Q

What shifts the aggregate demand curve?

A
  • IR effect
  • wealth effect
  • net export effect
45
Q

If congress cuts taxes what would happen to AD curve?

A

Shifts right

Q

If autonomous investment spending decreases, what happens to AD curve?

A

Shifts left

Shifts right

48
Q

A

Shifts left

52
Q

Under what conditions would an economy have a horizontal SRAS curve?

A

Recession or depression

53
Q

When would an economy have a vertical SRAS curve?

A

Full employment; no more goods can be produced

54
Q

When would an economy have a positively sloped SRAS curve?

A

Getting close to full employment; pressure on prices

55
Q

What would be the effect on real GDP if the economy had a horizontal SRAS curve?

A
  • no effect in PL

- increase in real GDP

56
Q

What’d be the effect on real GDP and PL if the economy had a positively sloped SRAS curve?

A

-increase in both real GDP and PL

57
Q

What’d be the effect on real GDP and PL if the economy had a vertical SRAS curve?

A
  • no effect on GDP

- increase in PL

58
Q

If unions grow more aggressive, and wage rates increase, SRAS curve shifts?

A

Left

59
Q

What would happen to SRAS curve if OPEC successfully increase oil prices?

A

Shift left

60
Q

What happens to SRAS curve if labor productivity increase dramatically?

A

Shifts right

61
Q

What happens to SRAS curve if giant natural gas discovery decreases energy prices

A

Shifts right

62
Q

What happens to SRAS curve if computer technology brings new efficiency to industry?

A

Shifts right

63
Q

What happens to SRAS curve if: gov spending increases, cuts in tax rates increase incentives to save, low birth rate will decrease labor force in future?

A

Nothing (demand side issue)

64

What happens to SRAS curve if research shows that improved schools have increased the skills of American workers and managers?

A

Shifts right
