  46. An

  47. Any

  50. Event: Stock market crash
    • 1.   Affects C, AD
    • curve

    • 2.   C
    • falls, so AD
    • shifts left

    • 3.   SR eq’m at
    • B.
    • P and Y  lower,
    • unemp
    • higher

    • 4.   Over time, PE falls,
    • SRAS
    • shifts right,
    • until LR eq’m at
    • C.
    • and unemp back

    at initial levels.
  51. Event:  Oil prices rise
    • 1.   Increases costs,
    • shifts SRAS
    • (assume
    • LRAS constant)

    • 2.   SRAS
    • shifts left

    • 3.   SR eq’m at
    • point B.
    • P higher, Y 
    • lower,
    • unemp
    • higher

    •   From A to B, stagflation,
    • a period of
    • falling output
    • and rising prices.
  52. The variables that influence money demand
    Y, r, and P
  53. A.  Suppose r rises, but Y and P are
    unchanged.  What happens to money demand?

    B.  Suppose P rises, but Y and r are
    unchanged. What happens to money demand?
    • A) Decreases
    • B)Increases
  54. MS
    curve is vertical: Changes in r do not affect MS,
    which is fixed by the Fed.

    curve is
    downward sloping: 

    A fall in r increases money demand.
  55. How the Interest-Rate Effect Works
    • A fall in P reduces money demand, which lowers r.
    • A fall in r increases I and
    • the quantity of g&s demanded
  56. federal funds rate
    • which banks charge each other on
    • short-term loans
  57. §To
    change the interest rate and
    shift the AD
    the Fed conducts open market operations
    to change MS.
  58. The Effects of Reducing the Money Supply
    • The
    • Fed can raise r by reducing the money supplyAn
    • increase in r reduces the quantity of g&s
    • demanded.
  59. Liquidity traps
    • §Monetary
    • policy stimulates aggregate demand by reducing the interest rate. 

    • §Liquidity trap: 
    • when the interest rate is zero

    • §In a
    • liquidity trap, mon. policy may not work, since nominal
    • interest rates cannot be reduced further. 

    • §However,
    • central bank can make real interest rates negative by raising inflation
    • expectations.
  60. §Expansionary fiscal policy

    increase in G and/or decrease in T

    §Contractionary fiscal policy

    • §a
    • decrease in G and/or increase in T

    • §shifts
    • AD left
  61. Multiplier effect
    the additional shifts in AD

    • that result when fiscal policy increases income and thereby increases consumer
    • spending
  62. The Multiplier
  63. The Crowding-Out Effect
    • §Fiscal
    • policy has another effect on AD

    that works in the opposite direction. 

    • §A
    • fiscal expansion raises r,

      which reduces investment,

      which reduces the net increase in agg demand
  64. Changes in Taxes
    • §A tax
    • cut increases households’ take-home pay.

    • §Households
    • respond by spending a portion of this extra income, shifting AD to
    • the right.

    • §The
    • size of the shift is affected by the multiplier and crowding-out effects. 

    • §Another
    • factor:  whether households perceive the
    • tax cut to be temporary or permanent.

    • §A
    • permanent tax cut causes a bigger increase in C—and
    • a bigger shift in the AD
    • curve—than a temporary tax cut.
  65. Natural-rate hypothesis
    • §the
    • claim that unemployment eventually returns to its normal or “natural” rate,
    • regardless of the inflation rate
  66. u-rate
    natural rate of unemp-(a(actual inflation -expected inflation))
  67. How an Adverse Supply Shock Shifts the PC
    • SRAS shifts left, prices rise, output &
    • employment fall.Inflation
    • & u-rate both increase as the PC shifts upward.
  68. Disinflation
    • §a
    • reduction in the inflation rate

    • §To
    • reduce inflation,
    • Fed must slow the rate of money growth,
    • which reduces agg demand.

    • §Short
    • run: 
    • Output falls and unemployment rises. 

    • §Long
    • run: 
    • Output & unemployment return to their natural rates.
