Title: Chapter 6. Economic Growth, Business Cycles, Unemployment, and Inflation


1
Chapter 6. Economic Growth, Business Cycles,
Unemployment, and Inflation
  • 6.A. Two Frameworks The Long Run and the Short
    Run
  • 6.B. Growth
  • 6.C. Business Cycles
  • 6.D. Unemployment
  • 6.E. Inflation

2
6.A. Two Frameworks The Long Run and the Short
Run
  • What lengths of time typically differentiate the
    short run from the long run?
  • Is anything assumed to be fixed or constant in
    the long run?
  • Is anything assumed to be fixed or constant in
    the short run?

3
6.B. Growth
  • Is the U.S. economy generally growing? Is the
    U.S. economy growing right now?
  • If the economy as a whole is growing, does that
    mean our income as individuals is growing too?
    What about the average income of individuals?
    What about the median income of individuals?
  • 6.B.1. Global Experiences with Growth
  • 6.B.2. The Benefits and Costs of Growth

4
6.B. Continued
  • Is growth a long run or a short run phenomenon?
  • Does growth appear to be driven by demand
    (decisions by buyers of products and services) or
    supply (decisions by makers of products and
    services)?

5
6.B.1. Global Experiences with Growth
  • Are current growth rates historically high or
    low?
  • Are average growth rates the same across
    different regions?
  • What regions generally have grown the fastest?
    The slowest?
  • When did economic growth start to be important
    (for practical purposes)?

6
6.B.2. The Benefits and Costs of Growth
  • Do all individuals benefit from growth?
  • On average, do individuals benefit from growth?
  • Does growth help elected officials face tough
    decisions?
  • Does growth help elected officials make tough
    decisions?
  • Are there costs to growth?

7
6.C. Business Cycles
  • Does the economy always grow at the same rate?
  • Can the size of the economy actually decline?
    What does the growth rate have to be for this to
    happen?
  • 6.C.1. The Phases of the Business Cycle
  • 6.C.2. Why Do Business Cycles Occur?
  • 6.C.3. Leading Indicators

8
6.C.1. The Phases of the Business Cycle
  • What names are given to the points in time when
    the size of the economy changes direction?
  • Which of those points of time is generally easier
    to notice, as it is happening?
  • What names are given to the periods of time
    between those two points?
  • Which of those periods is generally longer?

9
6.C.1. Continued
  • What are two names used to describe the economy
    doing well?
  • What are three names used to describe the economy
    doing poorly?
  • What is an additional name reserved for
    describing an extremely bad period for the
    economy?

10
6.C.2. Why Do Business Cycles Occur?
  • Does expansion and contraction in the economy
    appear to be driven by demand or supply?
  • Do those changes appear to be random?
  • Do long or strong expansions make the subsequent
    contractions worse?
  • Are expansions and/or contractions getting longer
    or shorter? More volatile or less?

11
6.C.3. Leading Indicators
  • Can peaks and troughs be predicted? How well? How
    far in advance?
  • What are some leading indicators?

12
6.D. Unemployment
  • 6.D.1. Unemployment as a Social Problem
  • 6.D.2. Unemployment as Governments Problem
  • 6.D.3. Why the Target Rate of Unemployment
    Changed
  • 6.D.4. Whose Responsibility is Unemployment
  • 6.D.5. How is Unemployment Measured?
  • 6.D.6. Unemployment and Potential Output
  • 6.D.7. Microeconomic Categories of Unemployment

13
6.D. Continued
  • How do we measure unemployment?
  • Unemployment is divided into four types - can we
    measure those?
  • What is the least serious type of unemployment?
    Why?
  • What is the third most serious type of
    unemployment? Why?
  • What is the second most serious type of
    unemployment? Why?
  • What is the most serious type of unemployment?
    Why?

14
6.D.1. Unemployment as a Social Problem
  • How long has unemployment been a social problem?
  • What does this have to do with cyclical (and
    perhaps structural) unemployment?
  • How was this related to the change from an
    agricultural to an industrial society?

15
6.D.2. Unemployment as Governments Problem
  • Why are elected governments sensitive to the
    amount of unemployment? What about governments
    that are not elected?
  • What does the text call the desired rate of
    unemployment? What is another common name for it?
  • What is the approximate desired rate of
    unemployment? Has this changed? Why isnt it zero?

16
6.D.3. Why the Target Rate of Unemployment
Changed
  • Can you list four reasons why the target rate has
    changed? Which one has to do with problems with
    coordination of government policies? Changed in
    government policies? Changes in society? Changes
    in the age profile?

17
6.D.4. Whose Responsibility is Unemployment
  • If you think that unemployment is the
    responsibility of the individual, then this is
    consistent with what sort of macroeconomist?
  • If you think that unemployment is the
    responsibility of the government (or society),
    then this is consistent with what sort of
    macroeconomist?

18
6.D.5. How is Unemployment Measured?
  • Who is counted in the labor force? Who is
    excluded?
  • How is the labor force divided?
  • How is the unemployment rate formed from that
    information?

19
6.D.5. Continued
  • What do we call someone who would like to work,
    but has given up looking for a job? Are they
    counted as unemployed? Why?
  • What do we call someone who has to work less than
    they would like to? Are they counted as employed
    or unemployed? Why?
  • Why is the unemployment rate a useful measure,
    even if it could be improved?

20
6.D.6. Unemployment and Potential Output
  • Do we always fully employ the labor force? How
    about machinery?
  • What do we call the level of output we would
    produce if we (hypothetically) employed all
    available labor and machines?
  • How did Okun relate the unemployment rate to that
    level of output?

21
6.D.7. Microeconomic Categories of Unemployment
  • Who is more likely to be unemployed, men or
    women?
  • What age group is most likely to be unemployed?
  • What race is least likely to be unemployed?
  • Are spells of unemployment more likely to be long
    or short?
  • What is the most likely reason for unemployment?

22
6.E. Inflation
  • Have nominal prices always risen through time?
  • How long have nominal prices been generally
    rising?
  • 6.E.1. Measurement of Inflation
  • 6.E.2. Real and Nominal Concepts
  • 6.E.3. Expected and Unexpected Inflation
  • 6.E.4. Costs of Inflation

23
6.E.1. Measurement of Inflation
  • What do we call a number that measures changes in
    the price of more than one product?
  • Can you construct one of these from data like
    Table 6-4 on the test?

24
6.E.1. Continued
  • What are the three most widely used prices
    indices?
  • Which one is broadest?
  • Which one is most appropriate for you?
  • Which one is released most often? Least often?
  • Which one might help us tell what prices are
    going to do in the future?

25
6.E.1. Continued
  • Price indices can be biased for four reasons. Can
    you identify those below?
  • Do people shift from expensive to cheap products?
  • Do manufacturers improve products without
    increasing their price?
  • Are new products counted in price indices? Why
    not?
  • Does Wal-Mart sell (only) junk?

26
6.E.2. Real and Nominal Concepts
  • If a value is measured in pieces of paper called
    dollars (or pounds, francs, yen, marks, or pesos)
    it is called what?
  • What is the problem with comparing nominal
    values? How is the severity of this problem
    related to the passage of time?
  • When we correct for this problem with a price
    index, what do we call the resulting value?

27
6.E.3. Expected and Unexpected Inflation
  • Do you expect prices to change through time?
  • Are your expectations of price changes accurate?

28
6.E.4. Costs of Inflation
  • Does a price increase make demanders or suppliers
    better or worse off? So, how is society affected
    by this?
  • If prices on most goods are rising, who is
    generally hurt people who also raise prices, or
    people who are stuck at the old prices?

29
6.E.4. Continued
  • Which is easier to deal with, expected or
    unexpected inflation? How is this related to
    borrowing and lending?
  • Does inflation make it easier or harder to plan
    your future purchases?
  • If there is inflation, would you shop-around more
    or less? Is this good for society?

30
6.E.4. Continued
  • Are governments and societies comfortable with
    certain rates of inflation?
  • If you get comfortable with current inflation,
    what happens to your expectations of future
    inflation?
  • If so, what do you do now?
  • What do we call those sorts of expectations?
  • What may this lead to?
