Introduction

We've been using the Equally - AD model to understand the macroeconomy. The vertical axis measures the Toll LEVEL which is the average level of prices in an economy. The horizontal axis measures REAL DOMESTIC OUTPUT which is all the goods and services produced in an economic system.

But WHAT NUMBERS exercise we put on the axes? How do we measure out the cost level and real domestic output?

We measure real domestic output with Existent Gdp and we measure the cost level with a Price INDEX.

In this lesson nosotros'll learn how to calculate real Gross domestic product and a cost index.

Measuring Existent Domestic Output: real GDP

We will use "existent GDP" to measure existent domestic output - the total corporeality of output produced in an economy . The table beneath lists the GDP for a few countries.

Annotation: 2007 data

Populations: US: 303 one thousand thousand Japan: 128 one thousand thousand Germany: 82 meg Mainland china: one,324 million Great britain: threescore million France: 61 million Italian republic: 59 million Canada: 32 meg Brazil: 192 one thousand thousand India: i,158 million S. Korea: 48 one thousand thousand Mexico: 112 million Commonwealth of australia: xx million

Note, that if you wish to COMPARE countries you should use GDP PER CAPITA which is Gross domestic product divided by the country's population (Gross domestic product per person). Fifty-fifty though the United States has the world'due south largest Gdp, it is not the highest GDP per capita. For a table of Gross domestic product per capita see: http://www.nationmaster.com/graph/eco_gdp_percap-economic system-gdp-per-capita

Definition: GDP

Gross Domestic Product is the full market value of all terminal goods and service due south that are produced in the economic system in one year.

This is 1 definition that should exist memorized. As you tin can run into information technology has three components.

(1) " total market value "

How tin can nosotros add the number of buildings produced to the number of candy bars produced to the number of cars produced, etc.? To practise this we need a common unit of mensurate. The unit of measurement of measure out for existent domestic output or real GDP is the market value or money

To get the "full" market value then one would think that you would add up the price times the quantity of everything produced:

GDP = SUM P x Q

Gdp = P this year ten Q this year

Gross domestic product equals the sum of the prices times quantities of everything produced in a twelvemonth

This, then, would give you the total market value of everything produced.

(2) " final appurtenances and services "

Only final goods and services are included to avert double counting

Final appurtenances are bought and used by the final consumer. When you buy a hamburger from McDonald'southward the value of the hamburger should exist included in GDP considering it is a terminal good.

Intermediate goods are bought so that they can be resold or further processed. When McDonald's buys buns, basis beefiness, and ketchup, the value of these purchases of intermediate goods are Non added to Gdp since they volition be added when a consumer buys the hamburger (a final good).

If we included the price of the hamburger AND the value of the bun, ground beef, and ketchup so these would exist counted twice.

Some other way to avoid double counting is to use the value-added method and only add what McDonald's spends on buns, ground beefiness, and ketchup, but and then NOT include what consumers spend on the hamburger.

The signal is nosotros want to go a measure of the market value of the final goods that an economy produces.

(3) " produced in ane twelvemonth "

Gross domestic product is a measure of what is produced or made in ane yr, therefore:

a. secondhand sales are not included because nothing new is produced, and
b. financial transactions not included because nothing is produced

A auto produced in 1999 is included in 1999'due south Gross domestic product. Therefore, if a used 1999 vehicle is sold in the year 2001 we would NOT once again include its cost in the Gross domestic product for 2001 since it was not produced then. We WOULD include the profits earned by the used car salesperson in 2001 since he or she did clean, advertise, and sell the used car in that year, but we would not include the value of the 1999 car itself.

Also, a lot of the "business news" that y'all hear concerning the billions of dollars spent on stocks and bonds each day does non affect the GDP directly.

When people buy stocks and bonds from whom do they buy them? If I buy $100 of stock in IBM, from whom do I buy information technology? I may buy it through a stock banker, but whose stock do I buy? I probably didn't purchase information technology from IBM (unless it was an IPO - Initial Public Offering), but rather I bought it from somebody who had bought information technology earlier. In other words, I bought "used" stock. Simply the principal signal is, when I buy $100 on IBM stock, goose egg is being produced so the $100 is not added to Gross domestic product.

Circular Menstruum Model

The round flow model can aid u.s. to understand the two approaches used to measure Gross domestic product.

i. expenditures approach
2. income approach

Arrow # 3 is real GDP (goods and services produced). This is output produced by business and sold in the production markets to consumers (households). This is what we want to measure. This is real domestic output. This is GDP.

To measure out this level of produced output we tin mensurate arrow #4 which are the expenditures spent on this output. This is the EXPENDITURES Approach. If something is produced and sold the amount sold should equal the amount produced. The only problem with this is what happens if something is produced one year but not sold in the next yr? If we merely added up the marketplace values of goods and services that were sold these items would be included in the incorrect year. To handle this problem we include items produced one yr and sold the next as changes in business inventories which ARE included the twelvemonth that they are produced.

We can besides measure out pointer #1 which is the income earned by households when they sell their resources (arrow #two) to businesses. The value of output produced (GDP) is equal to the value of ALL the income earned by anybody who had annihilation to do with producing the output. If a $twenty,000 machine is sold, then $20,000 was earned past everyone who was involved in producing and selling the car. So to mensurate Gdp ( the value of the products produced) we tin sum up all the income earned in producing that level of GDP. This is the INCOME APPROACH to calculating Gross domestic product.

Expenditures Approach

KNOW THIS !

GDP = C + Ig + Grand + Xn

ane. personal consumption expenditures (C) includes durable goods (lasting 3 years or more), nondurable goods and services.

2. gross private domestic investment (Ig)

Remember that we defined investment every bit the "accumulation of capital" and nosotros defined capital letter equally "manufactured resources" so investment occurs when businesses purchase capital. If a carpenter buys a hammer it is an investment. (Note: if an economist buys 100 shares of stock in Microsoft, it is NOT an economic investment.)

[Noninvestment transactions - despite how the term "investment" is used by the general public, investment does not include transfers of buying of newspaper assets (stocks and bonds) or real assets (houses, jewelry, art). Simply newly created capital is counted as investment.]

Economic Investment includes:

i) all final purchases of machinery, equipment, and tools by businesses
ii) all construction (including homes)
3) changes in inventories (To include items produced i year only sold the adjacent. If businesses are able to sell more they currently produce, this entry will be a negative number. )

gross vs. net domestic investment (In)

Gross investment is ALL NEW INVESTMENT and includes the 3 items listed above.

Net investment includes but the CHANGES to the nation's capital letter stock

Each year as new appurtenances and services are beingness produced, some of the existing capital equipment is wearing out and buildings are deteriorating. This is called "depreciation" or "consumption of fixed capital". Whereas gross investment adds to a country's stock of capital, depreciation reduces a country's stock of majuscule.

Net investment = Gross Investment - depreciation

In = Ig - depreciation

Internet investment is related to economic growth.

If net investment is positive so the country ends up with more majuscule at the end of the year than it stated with. Since we know that economic growth is caused by getting "more resources", if cyberspace investment is positive then the economy is growing, ("expanding economy").

What type of economic growth is this (1) increasing our potential from the 5Es or, (2) achieving our potential (or achieving full employment)?

It would be "increasing our potential" which is caused by getting more resources, meliorate resources, and better applied science.

If internet investment is negative this means that depreciation is greater than gross investment, or more than capital wears out than is produced so we would accept a "declining economy".

If gross investment (all new capital that is produced) EQUALS depreciation (capital that wears out) and so net investment will equal zero. there will exist no changes to amount of capital letter that a country has, and there will exist a "static economy".

3. regime purchases (Chiliad)

This includes purchases by all levels of regime (federal, land and local). Whenever the government buys something or pays somebody information technology is included in government purchases.

Regime purchases does Non include transfer payments. Transfer payments, by definition, are payments for which cipher is expected in return. Government transfer payments include welfare and social security payments, transfers from the federal regime to state government and from country to local governments. These are not included in GDP as government purchases considering when the regime transfers money, Zero IS PRODUCED and GDP only includes production. Of course, when people on welfare spend their regime check on food and hire so this does enter GDP as consumption (C).

four. net exports (Xn)

Net exports (Xn) included the value of all exports from a country minus the value of all imports.

Xn = X - M

If a state has a merchandise deficit then the value of imports is greater than the value of a country's exports and internet exports (Xn) is negative.

It should be obvious why exports is included in Gross domestic product and it should be obvious why imports should NOT be added to GDP. But why do we have to SUBTRACT imports from GDP. Subtracting is a lot dissimilar than not calculation.

Imports are subtracted from GDP because they were incorrectly included in consumption expenditures (C). Since imports are produced in another country they should not exist added to our Gross domestic product, simply they are added as art of of consumption so therefore they have to exist removed.

Practice Problem

Given the data below, utilise the EXPENDITURES APPROACH to summate Gross domestic product.

Use the information beneath to calculate the GDP of this economy using the expenditures approach. All figures are in billions. Personal consumption expenditures $400 Government purchases 128 Gross private domestic investment 88 Internet exports 7 Net foreign factor income earned in the U.S. 0 Consumption of fixed capital 43 Indirect business taxes 50 Compensation of employees 369 Rents 12 Interest 15 Proprietors' income 52 Corporate income taxes 36 Dividends 24 Undistributed corporate profits 22

ANSWER: Before scrolling downward, pick up some paper and a pencil and actually summate Gdp. DOING it yourself is better than reading it.

From the tabular array nosotros get:

Gdp	=	C	+	I	+	1000	+	Xn
GDP	=	400	+	128	+	88	+	vii

Gross domestic product = C + I + Yard + Xn = 400 + 128 + 88 + 7 = $ 623

The Real Earth - the 2007 United states Gross domestic product:

Income Approach --calculating national income (NI)

A second way to calculate GDP is by calculation up all INCOME - period #1 in the circular flow diagram below is the income received when resource are sold to businesses.

In that location are four types of resources (four factors of production):

1. labor
2. country
3. uppercase
4. entrepreneurial ability

Each of these resources types receives what economist phone call INCOME when they are sold:

1. labor receives wages
2. state receives rent
3. capital receives interest
4. entrepreneurial ability receives profits

So if we add up:

wages + rent + interest + profits

we should get Gdp -- well almost. Actually we become something called National Income (NI), or the income EARNED past the resource. the textbook goes through the calculation on how to get from NI to GDP - but we won't have to practise that in this class. What we will do is divide the profits earned by entrepreneurs into ii types: proprietor'southward income and corporate profits. Then:

NI = Wages + Rents + Interest + Corp. Profits + Prop. Income

[The new edition of our textbook now as well adds Taxes on product and imports including general sales taxes, excise taxes, business concern property taxes, license fees, and customs duties to the above to get NI -- we will not practice this either.]

Definitions:

national income: all income earned by American supplied resource, whether here or abroad, plus taxes on production and imports.

Compensation of employees includes wages, salaries, fringe benefits, salary and supplements, and payments made on behalf of workers like social security and other health and pension plans.

Rents: payments for supplying property resource (adjusted for depreciation it is net rent).

Interest: payments from private concern to suppliers of money uppercase.

Proprietors' income: income of incorporated businesses, sole proprietorships, partnerships, and cooperatives.

Corporate profits: After corporate income taxes are paid to regime, dividends are distributed to the shareholders, and the balance is left as undistributed corporate profits (also referred to as retained earnings).

Do Problem

Given the information below, use the INCOME Arroyo to calculate National Income (NI).

Apply the data below to calculate the Gross domestic product of this economy using the income approach. All figures are in billions. Personal consumption expenditures $400 Regime purchases 128 Gross private domestic investment 88 Net exports seven Internet foreign gene income earned in the U.Southward. 0 Consumption of fixed capital 43 Indirect business concern taxes l Bounty of employees 369 Rents 12 Interest 15 Proprietors' income 52 Corporate income taxes 36 Dividends 24 Undistributed corporate profits 22

Reply: Before scrolling down, pick up some newspaper and a pencil and actually calculate GDP. DOING it yourself is better than reading it.

.

NI = Wages + Rents + Interest + Corp. Profits + Prop. Income

.

.

From the tabular array we get:

NI	=	Wages	+	Rents	+	Interest	+	Corp. Profits	+	Proprietor'due south Income
NI	=	369	+	12	+	15	+	82	+	52

NI = Wages + Rents + Interest + Corp. Profits + Prop. Income

Corporate profits are used for three different purposes:

1. Corporate income taxes = 36
2. Dividends = 24
3. Undistributed corporate profits = 22

Corporate profits then equal 36 + 24 + 22 = 82 . On the exams I will give you "corporate profits".

NI = 369 + 12 + 15 + 82 + 52 = $ 530

GDP = C + I + Yard + Xn = 400 + 128 + 88 + 7 = $ 623

Every bit you can run across, National income does not equal Gdp. There are some expenditures (that are included in the expenditures approach) that are non income (therefore not included in the income approach). They are indirect concern taxes ( l), depreciation (43), and net foreign income factor ( 0 ), Merely, again, you won't have to do this in this course.

Other Social Accounts

Cyberspace Domestic Product (NDP)

National Income (NI)

NI = Wages + Rents + Interest + Corporate Profits + Proprietor's Income

NI is income EARNED by the factors of product (resource).

Personal Income (PI)

PI is the income RECEIVED by the factors of product (resources). To summate, take NI minus payroll taxes (social security contributions), minus corporate profits taxes, minus undistributed corporate profits, and add transfer payments.

Disposable Income (DI) is your SPENDABLE income. DI is personal income minus personal taxes.

ANSWERS:

a. Using the above information, determine GDP and NDP past the expenditure method.

GDP = $388
GDP = C + Igross + G + Xn
Igross = Inet + depreciation = 33 + 27 = 60
Gdp = 245 + 60 + 72 + xi = 388

NDP = $361
NDP + C + Inet + G + Xn
NDP = 245 + 33 + 72 + 11 = 361

or

NDP = Gdp - depreciation
NDP = 388 - 27 = 361

b. Summate National Income (NI) past the income method.

NI = $339
NI = wages + rents + interest + profits

Gross domestic product and Economic Well-Beingness

GDP per capita is often used to mensurate a country'southward well beingness or standard of living. The higher the Gross domestic product per capita for a country the amend off the country is. Merely there are some problems with using GDP per capita to measure a country's standard of living.

Problems with using Gdp to Measure the Standard of Living:

i. non-market place transactions are not included in GDP
two. leisure increases the standard of living simply information technology isn't counted
3. improved production quality often isn't accounted for in GDP
iv. Gdp does non business relationship for the limerick output
5. GDP does not account for the distribution of output
6. increases in GDP may impairment the environs and decrease the standard of living
7. the underground economy produces goods and services only they are not included in GDP
8. GDP does non account for a possible time to come turn down in output due to resources depletion.
ix. Noneconomic Sources of Well-Being like courtesy, criminal offence reduction, etc., are not covered in Gross domestic product.
10. We must utilize per capita GDP to compare the living standards of different countries.

1. non-market transactions are not included in GDP

GDP doesn't measure out some very useful output considering it is unpaid (homemakers' services, parental kid care, volunteer efforts, dwelling house improvement projects). Called non-market place transactions

2. leisure increases the standard of living only information technology isn't counted

GDP doesn't measure improved living conditions as a upshot of more leisure.

three. improved production quality often isn't deemed for in GDP

Gross domestic product doesn't measure improvements in product quality unless they are included in the price

4. Gdp does not account for the limerick of output

Gdp makes no value adjustments for changes in the composition of output. Nominal GDP simply adds the dollar value of what is produced; it makes no difference if the product is a semiautomatic rifle or a jar of baby food.

five. Gross domestic product does not account for the distribution of output

Gdp makes no value adjustments for changes in the distribution of income. Per capita GDP may give some hint as to the relative standard of living in the economy; but Gross domestic product figures do not provide information near how the income is distributed.

half-dozen. increases in GDP may harm the surroundings and subtract the standard of living

• The harmful effects of pollution are not deducted from Gdp (oil spills, increased incidence of cancer, destruction of habitat for wildlife, the loss of a clear unobstructed view).
• Gdp does include payments made for cleaning up oil spills and the cost of health care for cancer victims.

7. the underground economy produces appurtenances and services but they are not included in Gross domestic product

GDP does non include output from the Surreptitious Economic system. Illegal activities are not counted in Gdp (estimated to be around 8% of U.South. Gross domestic product). Legal economic activeness may as well be part of the "underground," usually in an endeavour to avoid tax.

Illegal activities are not counted in GDP (estimated to exist effectually eight% of U.S. Gdp).

Legal economical action may besides be office of the "cloak-and-dagger," usually in an effort to avoid taxation.

8. Gross domestic product does non account for a possible time to come pass up in output due to resource depletion.

9. Noneconomic Sources of Well-Being like courtesy, crime reduction, etc., are not covered in Gross domestic product.

10. Nosotros must use per capita Gross domestic product to compare the living standards of unlike countries.

Which country has a higher Gross domestic product, Switzerland or India? Which has a higher level of economical well-beingness:

• Switzerland:
  • GDP: $239.3 billion (2003 est.)
  • Population: seven,450,867 (July 2004 est.)
  • Gross domestic product per capita: $32,700 (2003 est.)
• India:
  • GDP: $iii.033 trillion (2003 est.)
  • Population: 1,065,070,607 (July 2004 est.)
  • GDP per capita: $ii,900 (2003 est.)

GDP per capita = GDP / population

REVIEW:

Do each of the post-obit cause Gdp to OVERSTATE the economic well-existence of a land or UNDERSTATE it?

ane. not-market place transactions (Does Gdp OVERstate or UNDERstate economic well-being?)

non included so, Gross domestic product UNDERstates well-beingness.

two. improved product quality (Does GDP OVERstate or UNDERstate economic well-beingness?)

not deemed for, and so GDP UNDERstates well-being.

3. more leisure (Does Gross domestic product Enlarge or UNDERstate economic well-being?)

not accounted for, and so GDP UNDERstates well-being.

4. the composition of output (Does GDP OVERstate or UNDERstate economic well-being?)

if "bad" things are being produced, and then GDP OVERstates well-existence.

v. the distribution of income (Does Gross domestic product Enlarge or UNDERstate economical well-being?)

an diff distribution of income would consequence in GDP OVERstating the well-beingness of most of a country'south population

half-dozen. the hugger-mugger economic system (Does Gdp Overstate or UNDERstate economical well-being?)

not deemed for, then Gdp UNDERstates well-being

vii. Gross domestic product and the environment (Does GDP Overstate or UNDERstate economic well-existence?)

harmful effects of pollution and costs of pollution reduction are not deducted from GDP, then Gdp OVERstates well-being.

8. Non-economic sources of well-being (Does GDP Overstate or UNDERstate economic well-being?)

non accounted for, so Gross domestic product UNDERstates well-being

9. Resource depletion (Does GDP Overstate or UNDERstate economic well-being?)

GDP overstates well-beingness since when we are depleting the resources our GP is loftier, only in a hereafter with fewer resources Gross domestic product will exist lower

10. per-capita income (Does Gross domestic product Overstate or UNDERstate economic well-being?)

GDP OVERstates well-being in countries with big populations and UNDERstates well-being in countries with small populations

Measuring the Cost Level and real GDP

Introduction

Nosotros've been using the AS - AD model to empathize the macroeconomy. The vertical axis measures the Toll LEVEL which is the average level of prices in an economy. The horizontal axis measures REAL DOMESTIC OUTPUT which is all the goods and services produced in an economic system.

Only WHAT NUMBERS do we put on the axes? How do we measure the price level and existent domestic output?

We have seen that we measure out real domestic output with Existent Gdp and nosotros have learned how to calculate GDP. In the lecture on unemployment and inflation nosotros learned how a Toll INDEX is used to measure out the price level. At present we will learn how to use a cost alphabetize to calculate Real GDP.

Nominal Gross domestic product and real Gdp

Nominal GDP is the market place value of all final goods and services produced in a twelvemonth. Nominal GDP is a (P 10 Q) figure including the quantity of every item produced in the economy in one year times its price THAT year.

Nominal Gdp is calculated using the current prices prevailing when the output was produced simply real GDP is a figure that has been adapted for price level changes.

Nominal Gdp = SUM (this twelvemonth's prices x this yr'southward quantities) = (P this twelvemonth ten Q this year)

Therefore, if nominal GDP increases is it because we are producing more than ( Q this year ) or is it because the Price Level increased ( P this year) ?

In fact it is possible for nominal Gross domestic product to increase fifty-fifty though the quantity produced has DECREASED. How?

Nom. GDP = (P this year 10 Q this year)

IF prices increased a lot, nominal Gdp would increase fifty-fifty if the quantity produced went down.

(P this yr x Q this year ) = Nom. Gdp

And so if we know that nominal GDP has increased, we yet do not know if we are producing more (and reducing scarcity) or if the price level has just increased.

Existent GDP is a measure of how much was actually produced. That is why it is used on the Equally/Advertizement graph as a measure of real domestic output (RDO). We mensurate RDO with existent GDP, not nominal GDP.

We summate real Gross domestic product by summing the quantity produced of everything in an economy times ITS Toll IN A BASE Yr. Since nosotros e'er utilize the same base year prices if the quantity produced increases information technology will increment existent GDP.

Existent GDP = SUM (base year'south prices x this twelvemonth's quantities) = P base year x Q this twelvemonth

By using the aforementioned toll level (base twelvemonth prices) we remove the effects of a higher cost level (inflation) and if REAL Gdp increases we know that the economic system is producing more and scarcity is being reduced.

existent GDP

• real GDP = SUM P base twelvemonth x Q specific year
• specific year'southward quantities x base years prices

Existent GDP = SUM (base year's prices x this twelvemonth's quantities) = P base twelvemonth x Q this yr

By using the aforementioned price level (base yr prices) we remove the effects of a higher cost level (inflation) and if REAL GDP increases we know that the economic system is producing more and scarcity is beingness reduced.

Calculating a toll index

To measure the cost level nosotros use a price index. A toll index is a measure out of the toll level as a percent of the price level in a Base year. This is different from inflation which is the charge per unit of increase in the price level from the PREVIOUS year.

Equally yous take read, to calculate a price index a year is selected as a base year. The average level of prices for that year is assigned a value of 100. So the toll levels for all other years are calculated as a percentage of the base yr.

GDP Price Index

definition

a price alphabetize is a measure of the cost of a specified drove of goods and services, chosen a "market basket", in a given year every bit compared to the price of an identical (or highly similar) drove of goods and services in a reference year (chosen the "base of operations year")

calculating a GDP price index

price index in a given year = (toll of market basket in a specific year / price of same market place basket in base of operations year) x 100

calculating real Gross domestic product

real GDP = Nominal GDP / Price Index

Actually, you then need to multiply information technology past 100.

real GDP = (Nominal Gdp / Price Index) x 100

The following information show nominal Gdp and the appropriate price index for several years.

Compute existent Gdp for each twelvemonth. In which year(southward) was there a recession (reject in existent GDP)?. All GDP are in billions.
