D. Why Business Cycles? (Causation at First Glance)
- From Chapter 6:
- fluctuations are caused by "shocks"; unexpected events that people and firms may have trouble adjusting to
- and price stickiness in the short run prvents markets form adjusting quickly resulting in changes in output and employment
- Why are there shocks? (20th: pp. 197-198; 19th: pp. 172-173; "Causation: A First Glance")
- irregular innovations
- unexpected productivity changes
- monetary factors
- political events
- financial instability (rapid asset price increases and decreases)
- Recession of 2007-2009
- housing prices
- Most agree that the level of aggregate spending is important, especially changes on capital goods and consumer durables.
II. Unemployment
A. The Unemployment Rate
- US:
- International: http://www.cbs.nl/en/figures/keyfigures/sip_600z.htm
B. What is Unemployment?
1. DefinitionThe percentage of the labor force unemployed at any time.
2. What is the labor force?
Persons 16 years of age and older who are not in institutions and who are employed or are unemployed (and seeking work)
a. who is included in the labor forceb. who is not in the labor force
c. part-time = employed
d. discouraged workers = not in labor force
Employees who have left the labor force because they have been unable to find employment.optional: How the government measures Unemployment - http://stats.bls.gov/cps/cps_htgm.htm

C. What Is "Full Employment"?
1. Definitions:(1) Use of all available resources to produce want-satisfying goods and services.(2) The situation when the unemployment rate is equal to the full-employment unemployment rate and there is frictional and structural but no cyclical unemployment (and the real output of the economy equals its potential real output).
2. Full employment is using all available resource to achieve the potential output

2) AD - AS Model (graph1, graph2)
3) LRAS Model
3. Full employment is about 5% unemployment, called
- the full employment rate of unemployment, or
- the natural rate of unemployment
- to understand how 5% unemployment is fullemployments we must know the three types of unemployment
4. Types of Unemployment
a. frictional unemploymentA type of unemployment caused by workers voluntarily changing jobs and by temporary layoffs; unemployed workers between jobs.
b. structural unemployment
Unemployment of workers whose skills are not demanded by employers, they lack sufficient skill to obtain employment, or they cannot easily move to locations where jobs are available.
c. cyclical unemployment -- business cycle
A type of unemployment caused by insufficient total spending (or by insufficient aggregate demand).
5. "full employment rate of unemployment" includes:
a. frictional unemployment PLUS
b. structural unemploymentc. also called the natural rate of unemployment
- The full-employment unemployment rate;
- the unemployment rate occurring when there is no cyclical unemployment and the economy is achieving its potential output;
- the unemployment rate at which actual inflation equals expected inflation.
6. why?: potential output is still achieved
potential output (ppc: graph / AS-AD:graph1, graph2)The real output (GDP) an economy can produce when it fully employs its available resources.

3) LRAS Model
7. Changes in the full employment rate of unemployment
- 1960's: 4%
- 1970's: 5%
- 1980's: 6%
- 1990's: 5%
- now: mayb 6% (or more)

D. Costs of unemployment
1. Lost Output
(not achieveing the POTENTIAL output, see graphs above)called the GDP gap
The amount by which actual gross domestic product falls below potential gross domestic product.GDP gap = actual GDP - potential GDP
negative GDP gap: potential > actual:
- economy is not producing as much as posible
positive GDP gap: actual > potential
2. unequal burdens
a. occupation
b. age
c. race
d. gender
e. duration
3. non economic costs

III. What is Inflation?
A. The Meaning of Inflation
A rise in the general level of prices in an economy.
The rate of increase in the price level
Inflation in the US:

a. GDP Price Index (GDP deflator)
b. CPI -- consumer price index
All Things Considered "Shopping for the Consumer Price Index" http://www.npr.org/templates/story/story.php?storyId=5568606 All Things Considered, July 19, 2006 · The Bureau
of Labor Statistics today released the monthly Consumer
Price Index, a key economic indicator that tracks
inflation. To track prices, the Labor Department sends
out hundreds of people around the country to monitor
prices for everything Americans buy -- from tires to food
and college tuitions. Robert Siegel went shopping with Caren Gaffney to find
out how the Consumer Price Index is compiled. On the
outing, Gaffney, a former telecommunications executive,
checked prices in two grocery stores in the Washington,
D.C., area. Siegel discusses the index with economists

Reserve's Michael Bryan and the University of Rochester's

2. calculating inflation
IN this year = (PI this year - PI last year) / PI last year
April of 2005: $2:30; CPI = 192
February of 2012: $3.63; CPI = 227
When did gasoline cost more?
This calculator uses the Consumer Price Index (1982-84=100) and the following simple formula to convert dollar amounts between two different years. Converted$ = (StartYear$ / StartYearCPI) * ConvertYearCPI Any time you compare dollar amounts over time, the amounts should be adjusted for price inflation. With this calculator, you can compare the real buying power of any dollar amount you enter in the box. For example, $100 in 1913 had the same buying power as $1,584.85 in 1996. |
Historical CPI:
3. rule of 70
Example: To determine the number of years it will take for the price level to double; divide 70 by the annual rate of inflation.
C. Causes: Theories of Inflation
Increases in the price level (inflation) resulting from an excess of demand over output at the existing price level, caused by an increase in aggregate demand.
2. cost-push (supply-side) inflation
Increases in the price level (inflation) resulting from an increase in resource costs like higher wage rates and raw material prices) and hence in per-unit production costs;
inflation caused by reductions in aggregate supply.
D. Complexities:
E. Effects of Inflation
b. savers
c. debtors and creditors
d. anticipated and unanticipated inflation
unanticipated: Increases in the price level (inflation) at a rate greater than expected.
2. output effects
results in LESS OUTPUT because:
