Q

Bureau of Economic Analysis (BEA) counts GDP in terms of:

A
  1. expenditures (any money spent on a final good)
  2. incomes (everyone’s net income at each stage of production)

both approaches will result in the same number in accordance with Say’s Law

A

“Inherent in supply is the where-with-all for its own consumption” -Jean Baptisle Say

A

short run ups and downs of the economy

33
Q

Great Recession

A
  • the last recession
  • began December 2007
  • started to grow June 2009
  • GDP fell by 4%
  • unemployment rate high of 10% (started at 5%)
34
Q

Unemployment Rate

A

percent of the labor force without jobs

35
Q

Labor Force

A

the sum of people who are employed or are actively looking for work

36
Q

Labor Force Excludes

A
  • minors
  • stay at home moms (house partners)
  • full time students
  • military
  • discouraged workers
  • anyone in prison
37
Q

discouraged workers

A

people who have given up looking for a job because they believe there are no jobs available for them

38
Q

Labor force and unemployment rate calculated by

A

US Bureau of Labor Statistics (BLS) calculate unemployment rate and Labor Force.

Last taken July 2015

39
Q

July 2015 Statistics

Civilian Noninstitutional Population, Labor Force, Unemployed, Discouraged Workers, Part Time For Economic Reasons

A

Civilian Noninstitutional Population = 250 million people
Labor Force = 157 million people
Unemployed = 8.3 million people
discouraged workers = .67 million people
Part time for economic reasons = 6.5 million people

40
Q

Labor force participation rate

A

Labor Force / Population

157 / 250 = 62.5%

41
Q

Unemployment rate

A

Unemployment / Labor Force

8.3 / 157 = 5.3%

42
Q

Types of unemployment

A
  1. Structural
  2. Cyclical
  3. Frictional
43
Q

Structural unemployment

A

persistent mismatch between the skills and atributes of workers and the skills and atributes sought after by employers.

ex. boybands, print based journalists

44
Q

Cyclical Unemployment

A

Caused by business cycle fluctuations.

ex. 2009 ford motor co. credit subsidiary cut 1200 jobs. (laid off)
* fear that what begins as cyclical will become structural

45
Q

Frictional Unemployment

A

short term. arises from the process of matching workers with available jobs. the workers choice. not a bad thing.

ex. you don’t agree with the requirements of your job so you quit to look for another job.

46
Q

Inflation fun facts

A
  • policy makers worry about it constantly
  • almost constantly positive rates of inflation since WW2
  • negative rate of inflation = rate of deflation
  • inflation rate was low and stable since the early 1980s
47
Q

Why do we care about inflation?

A
  1. high and/or unstable rates of inflation can harm the economy
  2. we want to know how much of nominal GDP growth is due to real growth and production verses nominal price growth
48
Q

Quantity theory of money.

Equation of Exchange

A

MV=PY

49
Q

M

A

Supply of money

50
Q

P

A

price level (average level of dollar prices)

51
Q

Y

A

real output of goods (real GDP)

52
Q

V

A

velocity (the number of times the typical dollar changes hands during a year)

53
Q

Growth rate is denoted by

A

%Δ

ex. %Δ M = growth rate of M

54
Q

MV = PY

is the same as

A

%Δ M + %Δ V = %Δ P + %Δ Y

55
Q

In General for any two variables X and Z

%Δ (XZ)

is the same as

A

%Δ X + %Δ Z

56
Q

%Δ (X/Z)

A

%Δ X - %Δ Z

57
Q

EXAMPLE
Per capita GDP = GDP / Population
Assume GDP grows 5% annually
Assume population grows 2% annually

how much does GDP per capita change?

A

GDP per capita grows at 3% annually

5% - 2%

58
Q

%Δ V

A

approximately 0

59
Q

purchasing power of money

A

if nominal prices increase, then the given dollar can purchase fewer goods.

when the price level goes up, inflation rate > 0, purchasing power of money goes down

60
Q

how does the bureau of labor statistics (BLS) measure the US price level

A

Price index = (Nominal cost of a “market basket” in a given year) / (nominal cost of that “market basket” in some base year) * 100

61
Q

In general, having low and stable rates of inflation is preferable to high and unstable rates of inflation because…

A
  1. Inflation can distort financial markets by transferring wealth from creditors to debtors (i.e., lenders to borrowers)
  2. if prices are “sticky” inflation can disrupt the efficiency of the price system
  3. Inflation can impose “shoe-leather” costs
  4. Hyperinflation can cause people to abandon use of their nation’s currency
