ECON Ch 19-22 Flashcards
Gross domestic product
The market value of all final goods and services produced in an economy in a given year.
Macroeconomics
The study of the economy as a whole, including topics such as inflation, unemployment, and economic growth.
Market value in GDP
Value each good and service in monetary terms. Price each good or service is sold for.
1 car valued at $50k –> GDP = $50k
Final goods or services in GDP definition
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.
In a given year part of GDP definition
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.
What do we include in the GDP?
GDP (Y) = consumption (C) + investment (I) + government purchases (G) + (exports (X) - imports (M)).
Exports - imports is considered net exports (NX).
Consumption
Spending by households on goods and services, not including spending on new houses (counted in investment).
What you buy.
Investment
Spending by firms on new factories, office buildings, and additions to inventories, plus spending by households and firms on new houses.
Firms expedentures on goods (unsold)
Government purchases
Spending by federal, state, and local governments on goods and services, such as teachers’ salaries, highways, and aircraft carriers.
Doesn’t include transfer payments, since those don’t result in immediate production of new goods and services.
Net exports
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
Do we include following in GDP?
- Tires ford buys to put on a car
- A used tire you buy for personal car
- A new tire you buy for personal car
- Value of car produced in us and exported to England
- Profit earned in 2004 fof a house you bought in 2001
- Commission earned by an employment counselor when she locates a job for a client.
- No because intermediate good
- No because used
- Yes
- Yes
- No because not this year
- Yes.
Why do we separate real and nominal GDP
Suppose the GDP rises. Is it because of production increasing or prices increasing?
Nominal GDP
The value of final goods and services at current year prices
Q 2011 * P2011
Real GDP
Value of final goods and services at base- year prices (typically 2009)
Q2017 * P2009
Nominal and real GDP general relation
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.
Price level
A measure of the average prices of goods and services in the economy.
Stable prices are desirable because they allow households and firms to plan for the future appropriately.
GDP deflator
Used to measure the price level
(NOM GDP / real GDP) * 100
Since the same in the base year, GDP def is 100 in base year.
What is gdp of us
$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.
GDP of Iceland and china?
$20 billion (smaller than us but larger per- capita (per person))
$11 trillion in China.
Interpret the GDP deflator
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)
Inflation
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.
Indexing
Name the base variable and then be consistent. Care about the difference between years, not the values themselves.
Other measures of total production and total income
Gross national product (production performed by citizens of a nation, including overseas production (larger than GDP)
National income: GDP - consumption of fixed capital (GDP-depreciation)
Personal income: income received by households; includes transfer payments but excludes firms retained earnings
Disposable personal income: personal income - personal tax payments. This measures amount households are able to spend or save.
How unemployment is measured in the US
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.
