Grappling with Inflation, Unemployment, and Growth
  • Costs of Inflation
  • Redistribution of Income
  • Informational and Uncertainty Costs
  • Institutional and Constitutional Costs
  • Menu and Shoe Leather Costs
  • Why Some Unemployment is Necessary
  • Flows In and Out of the Labor Market
  • Vacancies
  • Labor Market as a Matchmaker

  • Natural Rate of Unemployment
  • Cyclical Unemployment
  • The Phillips Curve

4
Policy Priorities
  • Since low inflation and low unemployment may
    conflict in the short run, policy makers must
    give one top priority
  • The Federal Reserve believes that
  • monetary policy does not affect the natural rate
    of unemployment
  • therefore, preventing inflation must be the
    primary goal of monetary policy

5
Legislative Basis of Policy
  • Employment Act of 1946
  • Required the government to use all of its powers
    to promote maximum employment, production, and
    purchasing power.
  • Full Employment and Balanced Growth Act of 1978
  • Requires the Fed chairman to present economic
    forecasts and targets for money supply growth to
    Congress twice a year

6
Effects of Inflation
  • Inflation makes buyers poorer because they must
    pay higher prices
  • Inflation makes sellers richer because they are
    paid higher prices
  • Since most people are both buyers (as consumers)
    and sellers (as owners of factors of production),
    the average persons income and wealth arent
    changed by inflation

7
Inflation Redistributes Income
  • Inflation redistributes income from those who do
    not, or cannot, raise their prices to those who
    can, and do, raise their prices.
  • People do not raise prices if inflation is
    unanticipated.
  • People can not raise their prices if they are
    fixed by a contract.

8
Inflation Redistributes Income from Lenders to
Borrowers
  • Suppose that you had planned to buy a pair of
    shoes for 100, but instead you lend the 100 to
    a friend for a year at 3 interest.
  • At the end of the year your friend repays you
    103.
  • During the year, inflation was 5, so now the
    shoes cost 105.
  • Your real rate of return was -2.

9
Real and Nominal Interest Rates
Nominal interest rate Real interest rate
Anticipated inflation
If lenders anticipate inflation, they add the
amount of expected inflation to the real
interest rate that they require to maintain their
purchasing power.
10
Costs of Inflation
  • Informational Costs
  • Prices are used to make comparisons between
    goods, but inflation distorts that information.
  • Uncertainty Costs
  • Inflation may distort and delay expenditures
    because it makes predicting future prices more
    difficult.

11
Costs of Inflation
  • Institutional Costs
  • Inflation undermines institutions and
    conventions, such as rules of thumb and
    contracts, which are based on relatively fixed
    prices.
  • Constitutional Costs
  • Inflation undermines the convention of money that
    forms the basis of exchange in the economy.

12
Costs of Inflation
  • Menu Costs
  • Inflation requires firms to spend time and money
    posting current prices in catalogues, menus, and
    on ticketed merchandise.
  • Shoe Leather Costs
  • Inflation increases the cost of managing cash
    balances.

Why Some Unemployment is Necessary
  • Flows In and Out of the Labor Market
  • About 10 million people change their job status
    every month.
  • Vacancies
  • Vacancies arise when workers leave their jobs
    and/or new jobs are created.
  • Labor Market as a Matchmaker
  • The labor market is not an instant matchmaker
    between unemployed workers and job vacancies

18
Why are Wages Above Equilibrium?
  • Unions may exert pressure for higher wages.
  • The government may impose a minimum wage that is
    above the equilibrium wage.
  • Efficiency wages are above equilibrium wages paid
    to attract and retain the best workers.

19
Strategies to Lower European Unemployment
  • Improve labor force skills with education and
    training
  • Reform employment security laws
  • Reduce regulation of work time and temporary jobs
  • Reform the level and duration of unemployment
    benefits

20
The Natural Rate of Unemployment
  • The natural rate of unemployment is the sum of
    frictional and insider-outsider unemployment.
  • The natural rate of unemployment has decreased
    0.6 to 1.1 percentage points from the mid 1980s
    to the late 1990s.

21
Causes of the Decline in the Natural Rate
22
Cyclical Unemployment
  • Cyclical unemployment occurs when real output is
    below potential output.
  • Cyclical unemployment exists because of
    coordination failures.
  • Problems that develop in an economy because
    decisions by individuals feed back into the
    economy, augmenting the effect of the initial
    decision.

Cost of Cyclical Unemployment
  • The cost of cyclical unemployment is the
    difference between actual output and potential
    output.
  • Okuns Rule of Thumb describes the relationship
    between unemployment and growth in GDP.

?Q is the percent change in real GDP ?U is the
change in the unemployment rate
28
Equity Costs of Unemployment
  • For individuals the costs of unemployment include
    lost income, a decline in skills, and loss of
    self-worth.
  • Unemployment is not shared equally among
    demographic groups
  • Teenage unemployment is higher than the overall
    unemployment rate.
  • The unemployment rate for blacks and Hispanics is
    higher than for whites.

30
The Phillips Curve
The Phillips curve represents a short-run trade
off between inflation and unemployment. If
policy makers choose to reduce unemployment from
8 (B) to 4 (A) the cost may be an increase in
inflation from 3 to 7.

Inflation and Unemployment 1954-2000
  • The Phillips curve which shows the historical
    relationship between inflation and unemployment
    has not remained stable over time.
  • Between 1958 and 1969, an inverse relationship
    between unemployment and inflation did exist.

32
Inflation and Unemployment 1954-2000
33
Inflation and Unemployment 1954-2000
  • Between 1970 and 1984, the inverse relationship
    broke down. Both inflation and unemployment were
    high in those years.
  • The inverse relationship between inflation and
    unemployment reappeared between 1985 and 1992,
    but disappeared again in 1992 when inflation and
    unemployment both decreased.

34
Short-Run and Long-Run Phillips Curves
There are two Phillips curves
A long-run Phillips curve which is vertical at
the natural rate of unemployment.
Long-Run Phillips Curve
Inflation
A short-run Phillips curve that shifts along the
long-run curve.
Short-Run Phillips Curve
Natural rate of Unemployment

35
Short-Run and Long-Run Phillips Curves
  • The long-run Phillips curve shows that
    policymakers cannot reduce unemployment below the
    natural rate by accepting more inflation.
  • The short-run Phillips curve represents a
    tradeoff between inflation and unemployment that
    changes as the curve shifts.

36
Sacrifice Ratio
  • The sacrifice ratio is the annual percentage
    point loss of output for every percentage point
    decline in the annual inflation rate.
  • The sacrifice ratio during the early 1980s was
    2.3.
