Q

Final goods or services in GDP definition

A

Good or service purchased by a final user. Used to calculate GDP.
Don’t include intermediate goods because we would double count
Ex. In 2016–> 50 tires at $10 each and 5 cars at $500. Of the 50 tires, 20 are used for the 5 cars (don’t include tires in GDP, just car (5005)). 20 are sold directly to consumer (count (2010)) and 10 are not sold (still produced, do count (10*10)).
If it is produced this year, include it. Doesn’t matter if sol or not.

Q

In a given year part of GDP definition

A

If you buy a newly constructed home in 2015 for $450K and sell it in 2016 for $600K, then it only counts the $450K in 2015 and nothing in 2016. Since the GDP measures production, and the house isn’t produced in 2016, don’t include.
But if we hire a real estate broker in 2016, then you include that salary.
Only counts new goods and services, not resold.

Q

Net exports

A

The value of exports - value of imports.
Inputs are American expenditure on foreign goods.

We want domestic production (production in US), so we add up value of goods sold to foreigners and subtract value of goods sold to Americans by foreigners.
Has been negative for us recently

Q

Nominal and real GDP general relation

A

After 2009, prices have gone up. So using today’s prices are larger, meaning nominal is bigger post 2009.
In 2009 they were equal
Before 2009, real was bigger.

Q

What is gdp of us

A

$18.5 trillion w base year of 2009
Since prices usually go up over time, if we used base year of 1980, GDP would be lower.
Need to be aware of the base year when we compare countries.

Q

Interpret the GDP deflator

A

Say we get the GDP deflator in 2012 is 116 (nominal/real in 2012)
This means that prices have gone up by 16% since the base year (2009)

Q

Inflation

A

The percent change in deflator from the previous year.

100 * (GDP Def 2012- DEF 2011) / DEF 2011
(NEW-OLD)/OLD
Interpret–> say we get 1.5%. This means the price level rose by 1.5% over this year.
We can also do this with the consumer price index.

Q

How unemployment is measured in the US

A

Household survey (~60,000 households and asks questions)
1. Have you worked for 1 hour in the past week?
If yes, you’re employed. If no, then a second question
Have you looked for a job in past 4 weeks?
Yes means unemployed.
No means not in labor force.

Q

How population is divided into different employment caterogires

A

Only look at people aged 16+
Of these people, some are not in the labor force (retired, students). Most of these people are not available for work
But some of them are available for work but haven’t looked for work. And even small portion are discouraged, stopped looking for job. In a prolonged recession, this number increases, but unemployment rate doesn’t account for this, so rate actually goes down
Labor force are rest of the working age population
Of these, either unemployed or employed. Rate = unemployed / labor force.

Q

Employement-population ratio

A

Employment / working age population * 100

The percentage of the working age population that is employed.

30
Q

Problems with unemployment ratio

A

Could underestimate unemployment
Because the distinguishing between people who are unemployed and not in labor force is tough (discouraged workers)
Only measures employment, not intensity of employment (full vs part time –> some are underemployed, not unemployed)

May overestimate:
May falsely claim to actively be looking for work
May claim to not be working to evade taxes or keep criminal activity unnoticed.

31
Q

Types of unemployment

A

Frictional, structural, cyclical

32
Q

Frictional unemployment

A

Short term unemployment that arises from the process of matching workers with jobs
Matching issues
For example, right after graduation, I get a job but haven’t started yet. Or I reject an offer from a company. Looking for good company. Not a problem, but rather, we encourage employee choice.

Job search, entering or re entering labor force or between jobs.

33
Q

Seasonal unemployment

A

Part of frictional
Some jobs fluctuate in avlaiability due to seasonal demand, like ski instructor or farm work
Releases raw and seasonally adjusted employment figures

34
Q

Structural unemployment

A

Economics change. We went from farming to manufacture to services to tech.
Say you were a farmer, need to learn how to manufacture and so on.
Not a bad thing, as the economy is moving forward

Unemployment that arises from a persistent mismatch between skills and attributes of workers and the requirements of jobs.

35
Q

Natural rate of unemployment

A

Frictional + structural
When all unemployment is due to frictional and structural factors, economy is at full employment. Always some unemployment, not bad though. Somewhere around 4-5 percent

36
Q

Cyclical unemployment

A

During recessions. Worry about this.

As you recover from recessions, unemployment from cyclical factors falls

37
Q

Deflation

A

Prices going down across time. Bad thing. Not seen in US

38
Q

Problem with GDP for inflation

A

GDP deflator reflects movement in GDP. Problem is we are looking at cost of living for average American. Americans consume in parts, not mentioned in GDP. For example, if I buy a BMW, it’s not in the GDP. Also, if we produce an export–> if that price goes up, GDP goes up. But we may never touch it as a consumer and it would be reported as inflation
So, we look at consumer price index.

39
Q

Consumer price index

A

A measure of the average change over time in the prices a typical urban family of four pays for the goods and services they purchase.
Build an imaginary basket and fix the basket (no changes in quantity).
Compare the price of the basket in one month to the price in the next month.

40
Q

How to calculate CPI

A

Base year is 1982, CPI is 100 then
CPI = expenditures in current year / expenditures in base year * 100
Keep quantity fixed, change prices.

41
Q

How to interpret CPI

A

If CPI = 150

This means prices have increased 50% since base year.

42
Q

Inflation measured by CPI

A

(CPI new - cpi old) / cpi old
The percentage change in the CPI.
Measures how much prices have gone up in the previous yea.

43
Q

Problem with CPI

A

Overestimates inflation
Doesn’t account the increase in quality. May not be making life more expensive.
Subs bias– consumers may change their purchasing habits away from goods that have increased in price.
New product bias– basket changes only every 10 years. Delay to including new goods like cell phones
Outlet bias– uses full retail price, but people get discounts
Overestimates true CPI by .5 to 1 percent.

For example, if price of tea goes up and coffee stays same, I’m just not going to buy as much tea. But CPI doesn’t say that, overestimates.

44
Q

Price level in year x in terms of price in set year (for example 2010):
How to get value in 2014 dollars given value in 1989 dollars

A

Price level in year x in terms of price in 2010 = CPI X/CPI 2010

Real receipt = nominal receipt * (CPI 2010/CPI X)

Value in 2014 dollars = value in 1989 dollars * (CPI 2014 / CPI 1989)

45
Q

Long run vs short run

A

Long run is growth

Short run is expamsion and contractions, recessions.

46
Q

Long run economic growth

A

The process by which rising productivity increases the average standard of living.
Use real GDP per capita to look at increase. Because this accounts for increased population– the amount of production in economy, per person, adjusted form changes in price level.

47
Q

What causes long term real GDP per capita growth

A

Labor productivity– the quantity of goods and services that can be produced by one worker or by one hour of work.

Why can the average American consume eight times as many goods and services now than in 1900?
Because the average American produces 8 times as many goods and sverices in an hour now than in 1900

So, what determines labor productivity growth?
Technological change, increases in capital per hour worked, property rights, NOT SHORT TERM GOVERNMENT CHANGES
L –>labor/ education health
K –> capital
Technology / productivity

48
Q

Capital affecting long term GDP growth

A

Increases in capital per hour worked
Capital is manufactured goods that are used to produce other goods and services.
The more capital a worker has available to use (including human capital, the accumulated knowledge and skills workers process), the more productive

49
Q

Technological change influencing GDP growth

A

Improvements in capital or methods to combine inputs into outputs (new technologies) allow for workers to produce more in a given period of time.
Entrepreneurs pioneer new ways to bring together the factors of production to produce better or lower cost products.

50
Q

Property rights influencing long term GDP growth

A

Market system cannot function unless fights to private property are secure
Governments can aid growth by establishing independent court systems.

51
Q

How to graph long term and short term economic growth

A

Real GDP per capita on y axis and time on x axis

Trend line is linear, but really short term fluctuations around the line.

52
Q

Business cycle

A

Alternating periods of expanding and contracting economic activity.
From peak to peak or trough to trough on the real GDP per capita vs time graph

53
Q

Expansion

A

When graph increases. Going from trough to a peak.

54
Q

Recession

A

When graph falls. Going from peak to trough. 2 consequence falling quarters are a recession.

55
Q

How inflation rate relates to recession and expansion

A

During expansions, demand is high relative to supply, so prices increase. High inflation
During recessions, demand is low relative to supply, prices increase more slowly or even decrease, low inflation or deflation

56
Q

Stabilization

A

Central bank and government reduce the fluctuation of output.
Makes the fluctuations closer to the trend line on the real GDP per capita vs time graph.

57
Q

Great moderation

A

Period since the mid - 1980s where fluctuations around trend line have been smaller.

Occurred because of increasing importance of services. Decreases the effect of business cycle on GDP
Also unemployment insurance. Still buy stuff during recession

58
Q

Unemployment during recession

A

Increases as GDP goes down.

59
Q

How are unemployment, GDP, and inflation affected by recessions and expansions

A

Recession:
U up, GDP down, inflation down

Expansion:
U down, gdp up, inflation up

60
Q

How severe was Great Recession

A 
GDP down 4%
Unemployment up (9-10%)
As opposed to natural rate of 4-5%
Inflation down. Desired was about 2%
61
Q

Growth across countries

A

As real gdp increases, growth rate decreases

More developed economies don’t grow as much.

62
Q

Different types of growth across type of economy

A
  1. Undeveloped / underdeveloped —> least real gdp, highest growth rate
  2. Emerging markets—> Russia, India, China. Centrally planned economy to a market economy. Growth rate of gdp is very high (>5%)
    These markets are in the middle of real gdp and have middle growth rates
  3. Industrialized. Larger economies with smaller growth rates.
63
Q

Model for long term economic growth

A

Labor productivity—> quality of goods and services that can be produced by 1 worker or by 1 hour of work.
2 main factors influence this:
1. Quantity of capital per hour worked
2 level of technology

Promote research and development
Patent law. Education/health

64
Q

Technological change

A

Change in the quantity of output a firm can produce using a given quantity of inputs.

65
Q

3 main sources of technological change

A
  1. Better machinery and equipment
    Inventions like the steam engine, machine tools, electric generators, and computers have allowed faster economic growth
  2. Increases in human capital
    Human capital is the accumulated knowledge and skills that workers acquire from education and training or from their life experiences
  3. Better means of organizing and managing production
    If managers can do a better job of organizing production, then labor productivity can increase. An example of this is the just-in-time system, first developed by Toyota. Thus involves assembling goods from parts that arrive at the factory exactly when they’re needed.
66
Q

Long run capital change

A

First units of capital most effective. Allows output per hour to increase most. Subsequent increases result in diminishing returns. Smaller incremental increases in output.

67
Q

Long run tech change

A

More effective way to increase output per hour in countries where capital is already high.

68
Q

Short term focus

A

Stabilization policies
If we are above trend line, stabilize. Lower the gdp. We don’t want a big boom and bust.
If we are below the trend line, fight for policy to move the gdp up.

69
Q

Savings

A 
Private savings (by households)
And public savings (by the government)
70
Q

Private savings

A

Household income not spent.
Household incomes includes payments for factors of production (Y) and transfer payment (TR). Households consume (C) and pay taxes (T)
So Sprivate = Y + TR - C - T

71
Q

Public savings

A

Government saves whatever it brings in but doesn’t spend. (May be negative, known as dissaving)
S public = T-G-TR

72
Q

Total saving

A

S private + S public = Y-C-G
So, savings = investment.
When S public is 0, government spends as much as it brings in. Balanced budget
Positive value is budget surplus
Negative value is budget deficit.
Funds deficits with selling treasury bonds (borrowing). Takes away from money aValiavible for investment spending

73
Q

Gross national product

A

Production performed by citizens of a nation, including overseas production (larger than GDP)
For example, ford production in Mexico is in GNP, not in GDP
Cars produced by Toyota in US is in GDP, not the GNP
