AP MACRO STUDY GUIDE
TEST 1
Scarcity is a condition that comes from human wants exceeding resources able to satisfy them
Forces us to make choices among alternatives based on our incentives
Economics is the social science that studies the choices individuals, businesses, and governments make to cope with scarcity and what influences those choices
Micro: Choices of individuals and businesses and how they are affected by governments
Macro: Total effect of choices made by businesses, individuals, and governments on the economy
Goods and services are objects and actions that people value and produce to satisfy human wants
We think about what goods and services are produced, how are they produced, and who are they produced for
Self-interest: Choices best for the individual who makes them
Social interest: Choices that are the best for society
Choice is a tradeoff
We choose from alternatives, but whatever is chosen we could have chosen something else
A tradeoff is an exchange; giving up one thing for another
Cost is what you must give up to get something
Opportunity cost is the highest value thing that you have to give up to get something
Benefit is what you gain from something
Benefit is a gain/pleasure from something, measured by what you are willing to give up
People make rational choices by comparing benefits and costs
Rational choice is a choice that uses the best available resources to best achieve the objective of who is making the choice
Compare costs and benefits
Marginal benefit > marginal cost
Most choices are how much choices made at the margin
Marginal cost is opportunity cost for one unit increase in an activity; Marginal benefit is what you gain for one more unit of something
Choices respond to incentives
An incentive is something that encourages or discourages an action
Consumption goods and services are g&s bought by individuals for personal enjoyment or to improve qol
Capital goods are bought by businesses to increase productivity
Consumption goods and services make up almost 80 percent of the economy
Manufacturing is about 13%; others add up to about 9%
We produce with the factors of production; Land, Labor, Capital, and Entrepreneurship
Land is natural resources such as minerals, water, air, plants, animals, farmland, and forests
Labor is the time and effort devoted to producing goods and services; human capital is the knowledge and skills obtained from education, training, and experience
Capital is tools, instruments, machines, buildings, and items that are used by businesses to produce goods and services(Not stocks and bonds)
Entrepreneurship is the human resource that organizes labor, land, capital
Incomes come from the sale of services of factors of production
Land gets rent, labor gets wages, capital gets interest, entrepreneurship gets profit/loss
Country production structures are similar, but differences in human capital and physical capital and how large food production make the difference between countries
Advanced economies are richest
Emerging is in the middle
Developing is the lowest
OC: What must be given up to get something else
PPF: a boundary between combinations of goods and services that can and can’t be produced
PPC illustrates ppf
Considers attainable and unattainable combinations, efficient and inefficient production, and tradeoffs/free lunches
Can produce inside the frontier, but not outside
Producing on the points on the PPF is efficient(every point except G)
When we are on the PPF we have to make a tradeoff: give to get
Inside the ppf we can move anywhere we want without tradeoffs
***
Steeper the PPF the higher the opportunity cost is
When the resources of an economy increase PPF moves outwards
Absolute advantage is when a person or nation is more productive than another; takes less time to produce more goods or uses fewer inputs
Comparative advantage is the ability of someone to perform an activity or produce a good/service at a lower opportunity cost than others
You can have absolute advantage in both, but not comparative advantage
Liz should produce smoothies, Joe should produce salads due to comparative advantages
A market is an arrangement that brings buyers and sellers together
Demand is the buyers, supply is the sellers
Anything can be traded
Quantity Demanded is amount of a good/service/resource people are willing and able to buy
Law of Demand states that when other things stay the same, if the price of a good falls, quantity demanded increases, and if the price of a good rises, quantity demanded decreases
Demand is the relationship between quantity demanded and the price of a good
Law of Demand explains downward slope
Change in demand causes curve to change
TRIBE shifts demand
Tastes: Due to information or new goods, people will avoid/gravitate toward a good or buy a different good
Related Goods: Substitutes and Complements
Substitutes move in the same direction: When the price of a substitute rises, demand for a good increases, and vice versa
Complements move in opposite directions: When the price of a complement decreases, demand for the good increases, and vice versa
Income: Income moves in the same direction as demand
However for Inferior goods when income increases demand decreases
Buyers: More buyers higher demand
Expectations:
Expected Future Prices: A rise in the expected FUTURE price of a good increases current demand, and a fall leads to a decrease
Expected Income: Expected increase in future income means increase in the demand of goods
When the quantity demanded changes, there is movement along the curve
Quantity supplied is the amount of a good/serice people are willing and able to sell at a certain period at a certain price
Law of supply states if price rises, quantity supplied rises
Leads to Upward Sloping
ROTTEN shifters
Related Goods: When price of substitute goods increase, supply decreases: sub decrease, supply increase
When price of complement increases, supply of base good increases, vice versa
Other Inputs: Wages, oil, steel etc.; when their price increases supply decreases because it costs more to produce
Taxes: Taxes make it more expensive to produce and decrease supply; subsidies make it less expensive and increase production
Technology: Better technology leads to more supply
Expectations: Expecting higher future prices = more supply
Number of Firms: More sellers means more supply
Equilibrium is when the quantity supplied = quantity demanded
Price is the regulator of a market
A shortage is when quantity demanded > quantity supplied: price rises to make up for it
A surplus is when quantity supplied > quantity demanded: price falls to make up for it
Questions to consider: Does the event change demand or supply? Does it increase demand or supply? What are the new equilibrium price and quantity
TEST 2
Market price; how much something is worth, what is paid for it
GDP(Gross Domestic Product) is the market value of the final goods and services produced within a country in a given time period
It is calculated quarterly(every 3 months) and is the scorecard of a given country’s economic health
Final goods and services are goods produced for a user and not as a part of another good or service
Intermediate goods are bought by a firm to use as part of their good or service
For a good to count as part of a country’s GDP, it has to be produced in that country
Households, firms, governments, and the rest of the world buy goods and services
Consumption, investment, government spending, and net exports
Expenditure approach = Y= C + I + G + NX(X-M)
Consumption is household expenditure, investment is new capital bought by firms(NOT STOCKS AND BONDS), government spending is self-explanatory, net exports consists of goods and services sold to foreign nations, households, and firms, and imports consist of goods and services bought from foreign governments
Consumption makes up most of the expenditure
The income approach shows how households receive and save their income and pay some in taxes
Uses and Limitations of GDP
Real GDP shows the standard of living over time, tracks the course of the business cycle, and compares the standard of living among countries
Real GDP removes inflation and accurately compares different times
Potential GDP is the value of real GDP when the factors of production(land,labor capital, and entrepreneurship) are fully employed
Real GDP fluctuates around potential GDP.
Fluctuations in the expansion of real GDP is part of the business cycle; movement of total production and economic activity
Contains expansions, peaks, recessions, and troughs
A recession is when real GDP is negative for six months or more
To compare different living standards across countries, we convert real GDP into a common currency/set of prices known as purchasing power parity
Compares country currencies with a basket of goods approach
Things excluded from GDP
Household production; cooking, cleaning, housework
Underground production; economic activity hidden from government to avoid taxes and regulations or production that is illegal
Leisure time
Environmental quality; GDP does not reflect pollution and other similar factors
Health and life expectancy and political freedom are not reflected
Income Approach
Different to expenditure
Wage income and net operating surplus
Wage income is the payment for labor services; net wages and salary + benefits such as health care, social security, and pension fund contributions
Interest rent and profit together are known as the net operating surplus
Interest is the income households receive on loans minus the interest they pay for borrowing
Rent is the payment for the use of land and other things
Profit is the profits of corporations and small businesses
Income approach is calculated with the net domestic product at factor cost; sum of wages, interest, rent, and profit
We also need to adjust from factor cost to marke prices and from net product to gross product
To convert from the value at factor costs, we add indirect taxes and subtract subsidies
Income measures net product, expenditure measures gross
To get to gross we must add depreciation(decrease in value of capital from use & obsolescence)
There is also a statistical discrepancy between expenditure and income approaches, and we subtract GDP income total from the expenditure total
GNP(Gross National Product)- market value of all the final goods and services produced anywhere in the world by the factors of production supplied by a country
GNP = GDP + Net Factor Income from abroad
Real GDP- value of final goods and services produced in a given year expressed in the prices of the base year(adjusted for inflation)
Nominal GDP- value of final goods and services produced in a given year expressed in the prices of that same year
CPI
CPI is a measure of the average of the prices paid by urban consumers for a fixed market basket of consumer goods and services
Calculated monthly
Reference base period is 100 from 1982-1984
Three stages: selected basket, conducting monthly price survey, calculating the CPI
Basket is in the budget of an average urban household; not updated monthly and influenced by Consumer Expenditure Survey
Monthly price survey is when BLS employees check the prices of 80,000 goods and services in the basket in 30 metropolitan areas
Measures price changes, so the prices recorded must refer to the same terms
(Current period cost/over base period ) * 100
Inflation rate is the percent change in the price level from one year to the next
((Current CPI- Previous CPI)/Previous CPI)*100
Other Price Level Measures
CPI does not measure the cost of living because it does not measure all the components of living cost and some of the components are not measured exactly
CPI has potential biases
New goods; they do better than old goods they replace and cause an upwards bias
Better goods cost more than what they replace; a price rise that is a payment for improved quality is not inflation but still might be counted as that
Substitution: When the price of one good rises faster than another, more of the cheaper good will be bought
CPI does not account for this
When prices rise, discount stores are used more; CPI also doesn’t account for this
CPI is estimated to be 1.1% per year
CPI biases leads to the distortion of private contracts; wage contracts are linked to it and bias can lead to unexpected outcomes
Also causes increase in government outlays and decreases in taxes; ⅓ of outlays are tied to cpi, affected things like social security, food stamps, school lunches, etc.
Nominal vs Real
To compare dollar amounts at different dates we need to know the CPI at these dates
These adjectives apply to GDP, wage rate, and interest rate
Real GDp is nominal GDP multiplied by the ratio of a price index in a different year
GDP price index is an average of the current prices of all the goods and services included in GDP expressed as a percentage of the base years
GDP Price Index/Deflator = (Nominal GDP/Real GDP) * 100
Real GDP is calculated by multiplying the quantity of output in one year by the prices in a base year.
Wage rate is the hourly wage rate measured in current dollars
Real wage rate is average hourly wage rate compared to another reference base year
Real interest rate is just nominal interest rate- inflation rate
Unemployment
Working-age population is the total number of people aged 16+ who are not in jail, hospital, military, or another kind of institutional care
Divided into labor force and not in labor force
Most of those not in are in school or retired
Labor force = employed + unemployed
Employed: worked an hour in a paid job or 15 hours unpaid or not working but had jobs where they had a temporary absence the week before the survey
Unemployed: had no employment and were available for work the week before the survey
Both had made efforts to find employment in the precious four weeks or wanted to be recalled to a job from which they had been fired
We need to focus on the unemployment rate, employment-population ratio, and labor force participation rate
Unemployment omits the following types of labor
Marginally attached workers do not have a job, are willing/available to work, but have not made efforts to find a job in the past for weeks and have looked for work sometime in the recent past
Discouraged workers are marginally attached workers who don’t make efforts to find a job because their previous attempts were discouraging
Part time workers who want full-time work are also omitted
Full time = >=35 hours a week
Part time = <35 hours a week
Unemployment rate increases in recessions and decreases in expansions
Participation rate increased between 1960 and 1999; women participated more, men less
Measures of unemployment
U-3 is main and official, percentages of labor force
Unemployment and full unemployment
There is unemployment because the labor market is always churning
New jobs are recreated and old jobs die
Three types of unemployment: Frictional, Structural, and Cyclical
Frictional arises from people entering and leaing the labor force; it is permanent and healthy
Structural arises from changes in technology or internationall competition; changes in skills needed to perform jobs
Cyclical is essentially bad; fluctuating unemployment over the business cycle; increases during a recession, decreases during an expansion
Natural unemployment arises from frictional and structural unemployment; NOT CYCLICAL
Natural unemployment rate = 4.5-5.5%
Full employment occurs when the unemployment rate = natural unemployment rate
Age distribution of populace(young = new job seekers), pace of structural change(tech changes), real wage rate(rise = surplus of labor), unemployment benefits(increase NRU because less opportunity cost for the job search)
At full employment there is no cyclical unemployment
At the trough of the business cycle, cyclical unemployment is positive
At the peak, cyclical unemployment is negative
POTENTIAL GDP
VALUE OF REAL GDP WHEN THE ECONOMY IS AT FULL EMPLOYMENT
THEORETICAL: WORLD WHERE EVERYTHING IS PERFECT
WE PRODUCE THE GOODS THAT MAKE UP REAL GDP USING FACTORS OF PRODUCTION: LABOR, PHYSICAL CAPITAL, LAND, AND ENTREPRENEURSHIP
QUANTITY OF LABOR IS NOT FIXED; DEPENDS ON CHOICES OF PEOPLE AND BUSINESSES
REAL GDP DEPENDS ON QUANTITY OF LABOR EMPLOYED
UNEMPLOYMENT RATE FLUCTUATES AROUND THE NATURAL UNEMPLOYMENT RATE; REAL GDP FLUCTUATES AROUND POTENTIAL GDP
WHEN UNEMPLOYMENT RATE > NATURAL UNEMPLOYMENT RATE, REAL GDP < POTENTIAL GDP
WHEN UNEMPLOYMENT RATE< NATURAL UNEMPLOYMENT RATE, REAL GDP > POTENTIAL GDP
UNEMPLOYMENT RATE FLUCTUATES AROUND THE NATURAL UNEMPLOYMENT RATE; FALLS BELOW THE NATURAL RATE WHEN CYCLICAL UNEMPLOYMENT IS NEGATIVE, RISES ABOVE WHEN CYCLICAL UNEMPLOYMENT IS POSITIVE
PRODUCTION FUNCTION SHOWS THE RELATIONSHIP BETWEEN QUANTITY OF REAL GDP AND QUANTITY OF LABOR EMPLOYED WHEN OTHER INFLUENCES ON PRODUCTION REMAIN THE SAME
BOUNDARY BETWEEN ATTAINABLE AND UNATTAINABLE
DIMINISHING RETURNS; TENDENCY FOR EACH ADDITIONAL HOUR TO PRODUCE SMALLER AMOUNTS OF REAL GDP
LABOR MARKET CONSISTS OF DEMAND AND SUPPLY FOR LABOR
QUANTITY OF LABOR DEMANDED IS THE TOTAL LABORS ALL FIRMS PLAN TO HIRE IN A GIVEN TIME PERIOD AT A REAL WAGE RATE
DEMAND FOR LABOR IS THE RELATIONSHIP BETWEEN THE QUANTITY FOR LABOR DEMANDED AND REAL WAGE RATE; LOWER REAL WAGE RATE= GREATER QUANTITY OF LABOR DEMANDED; HIGHER RWR = LOWER QOL DEMANDED
FIRMS HAVE TO COMPARE THE EXTRA OUTPUT FROM AN HOUR OF LABOR W/ REAL WAGE RATE
EACH ADDITIONAL HOUR PRODUCES LESS OUTPUT
SUPPLY FOR LABOR IS THE NUMBER OF LABOR HOURS HOUSEHOLDS IN THE ECONOMY PLAN ON WORKING
QUANTITY OF LABOR SUPPLIED IS THE NUMBER OF LABOR HOURS THAT ALL HOUSEHOLDS IN THE ECONOMY PLAN TO WORK DURING A GIVEN TIME PERIOD AT A GIVEN REAL WAGE RATE
SUPPLY OF LABOR IS THE RELATIONSHIP BETWEEN THE QUANTITY OF LABOR SUPPLIED
LOWER RWR = LOWER SOL PROVIDED; INCREASE IN RWR = INCREASE IN SOL
QUANTITY OF LABOR SUPPLIED INCREASES BECAUSE HOURS PER PERSON INCREASES AS RWR INCREASES(higher opportunity cost for leisure), HIGHER LABOR FORCE PARTICIPATION RATE(people work when rwr exceeds value of other productivie activities), AND OTHER INFLUENCES(Work-leisure depends on after-tax wage rate (wage actually received by household).Income tax rates lower supply or labor. Unemployment benefits lower the OC of job search.)
A RISE IN THE RWR ELIMINATES A SHORTAGE OF LABOR BY DECREASING THE QUANTITY DEMANDED AND INCREASING THE QUANTITY SUPPLIED
A FALL IN THE RWR ELIMINATES A SURPLUS OF LABOR BY INCREASING THE QUANTITY DEMANDED AND DECREASING THE QUANTITY SUPPLIED
WHEN THERE IS NO SHORTAGE OR SURPLUS, THE MARKET IS IN EQUILIBRIUM
FULL EMPLOYMENT IS WHEN THE QOL DEMANDED = QOL SUPPLIED
IN THIS GRAPH, RWR IS 50 AND FULL EMPLOYMENT QUANTITY OF LABOR IS 200 BILLION
EQUILIBRIUM = FULL EMPLOYMENT
IN THIS SCENARIO REAL GDP = POTENTIAL GDP
Natural Rate of Unemployment
NRU is the unemployment rate that a healthy economy will have
4.5-5.5, 4-5%
Fiscal and monetary policies are used to reach full employment
To understand the amount of frictional and structural unemployment that exists at the natural NRU, we look at job search and job rationing, causes of unemployment
Job search is looking for an acceptable vacant job; depends on demographic change, unemployment benefits, and structural change
Demographic Change: Increase in the proportion of population that’s working age and increase in the entry rate into the labor force increases the unemployment rate
Unemployment Benefits: Higher unemployment benefits = lower OC of not having a job and you get to search longer; vice versa works too
Structural change: Technological changes influence labor market flow and unemployment
Job rationing occurs when the rwr is above the full-employment equilibrium level; real wage rate might be set above the full-employment equilibrium level for three reasons
Efficiency Wage: Firm paying over market wage(full unemployment equilibrium wage rate) to induce a higher work effort
Minimum Wage: Government sets a minimum wage above the equilibrium wage rate, leading to unemployment results
Union Wage: Labor unions operate in some labor markets and agree a wage rate with employers/firms
Classical macroeconomics
Market economy gives best macroeconomic performance
Aggregate fluctuations are a natural consequence of an expanding economy with rising living standards
Government intervention hinders the ability of the market to allocate resources efficiently
Fell off in 1930s because of Great Depression and high unemployment
Suggested that Great Depression would end but provided no method
Bastiat;Ricardo;Smith;Hume
Keynesian macroeconomics
Market economy is unstable and active government intervention is needed to achieve full employment and economic growth
John Maynard Keynes
Limited consumer spending led to the GD; suggested that his policy would cure short term unemployment but increase it in the future
Came true in 1960s-1970; inflation exploded, growth slowed, unemployment increased
Recession of 2008 revived interest in Keynes ideas; juggernaut of 1900s macroeconomics
Monetarist macroeconomics
Classical view of the world is correct, but we need to account for fluctuations in the quantity of money that generate the business cycle
A slowdown in the growth rate of money causes recession;a decrease in the quantity of money aused the GD
Milton Friedman
Quantity of money plays a huge part in fluctuations

Economists measure the health of the economy by looking at key economic indicators like GDP, the unemployment rate, the the inflation-measuring CPI.
The circular flow model shows how households, businesses, and the government interact
GDP is the dollar value of all final goods and services produced within a country in one year
There are three types of unemployment: frictional, structural, and cyclical; the economy is at full employment when there is no cyclical unemployment
Real GDP is adjusted for inflation and expressed in constant/unchanging dollars. Nominal GDP is not adjusted for inflation.
AGGREGATE DEMAND
Demand for every good and service
Quantity of real GDP demanded
Total amount of FINAL goods and services produced in a country that people, businesses, and governments and foreigners plan to buy
Expenditure approach; Y= C+I+G+Nx
Aggregate demand is the relationship between the quantity of real GDP demanded and the price level when all other influences on expenditure plans remain the same
When price rises, quantity of Real GDP demanded decreases
When the price falls, quantity of real GDP demanded increases
Sloped down because more is bought when price level falls
Also when prices increase in one country less people buy from that country
Price level changes affect the buying power of money, real interest rate, and the real price of exports and imports
When price goes up, buying power of money decreases, and quantity of real GDP demanded decreases
When prices falls money buys more and real GDP demanded increases
When price level rises, real interest rate rises
Price rise increases the amount of money people want to hold and increases demand for money
When demand increase, NIR increases
Rise in nominal interest rate = rise in real interest rate
Lower the interest rate the likely you are to buy something
Quantity of real GDP demanded decreases as real interest rate rises
Real prices of net exports
When US prices rise and other things are consistent, prices in other countries do not change
Rise in price level makes US goods more expensive than foreign goods
People spend less on US goods and more on foreign goods
When price level changes more in one country than other, exchange rate changes to neutralize the price change
Factors that shift aggregate demand: expectations about the future, state of the world economy, fiscal and monetary policy
Expectations
Increases in expected future income increases the amount of consumption goods people buy now
Increases in expected future inflation increases aggregate demand because people buy goods now before the prices rise
Increase in expected future profit increases firms investing now and increases aggregate demand
World Economy
The foreign exchange rate and foreign income influence aggregate demand.
The foreign exchange rate is the amount of foreign currency you can buy with a U.S. dollar.
Other things remaining the same, a rise in the foreign exchange rate decreases aggregate demand.
Example: $1 to 100¥ exchange rate. $125 Motorola or 12,500¥ Fujitsu phone? Depends on PL!
An increase in foreign income increases U.S. exports and increases U.S. aggregate demand.
A decrease in foreign income decreases U.S. exports and decreases U.S. aggregate demand.
Fiscal and Monetary Policy
Fiscal- Actions of Congress and President
Changing taxes, transfer payments, government spending
Monetary Policy- Actions of the Fed and Central Bank
Federal Reserve influences aggregate demand; stimulus increases demand, taxes decrease
Changing quantity of money and interest rate
Aggregate demand multiplier is an effect that magnifies change in expenditure plans and brings potential large fluctuations in aggregate demand
Increase in investment increases AD and income
Increase in income leads to an increase in consumption spending
AD increases by more than the initial increase
Quantity of real GDP supplied is the total amount of final goods and services that firms in the U.S. plan to produce
All goods and services
This depends on labor employed, capital, land, and entrepreneurship
At full employment real GDP = potential GDP; the quantity of labor demanded and the quantity of labor supplied at the equilibrium real wage rate
Quantity of labor employed fluctuates around the full employment level
Aggregate supply is the relationship between the quantity of real GDP supplied and the price level when all other influences on production plans remain the same
When the price level rises, the quantity of real GDP supplied increases(people want to sell)
Vice versa(when prices are lower, you don’t wanna sell)
Rising price indicate that businesses should expand production to meet aggregate demand
Only influence on production plans is the price level
Money wage rate and money prices of other resources
Shifters of the AS curve
Key resources/costs(oil steel labor, cost/availability of key resources)
Productivity(machinery, capital, new tech)
Size and Quality of Labor(Immigration, skilled workers, human capital)
Change in Expected price level(different from price level, wages are negotiated in response to the increase
Gov’t Action(taxes, regulations, subsidies)
AS changes when influences on production plans other than the price level changes
AS changes when potential GDP changes
Watch the money wage rates, money prices, and anything that changes potential GDP
A change in the money prices of other resources changes aggregate supply because it changes firms’ costs
Higher prices of other resources, the higher firms costs and firms want to supply less at each price level
Decreases AS
Economic Trends and Fluctuations
AS-AD Model
Basis of macroeconomics
Used to explain business cycle fluctuations in real GDP and price level with Aggregate Supply and Demand
Movements of the curve predict the effect on events on rGDP and PL
Equilibrium occurs when the quantity of real GDP supplied equals the quantity of real GDP demanded
When firms cannot meet demand, production needs to be increased and prices need to be raised
When firms can’t sell their production, they lower production and prices
Different types of equilibrium to consider
Full-Employment Equilibrium- when equilibrium real GDP = potential GDP when AD intersects AS
Recessionary gap exists when potential GDP exceeds real GDP, causing the price level to fall
Inflationary gap exists when real GDP exceeds potential GDP, causing a rising price level
When real GDP is not at potential GDP, the money wage rate gradually increases or decreases to bring full employment
In a recessionary gap, there is a surplus of labor, and firms higher new workers a a lower wage rate
Price levels fall, real GDP increase
In an inflationary gap, there is a shortage of labor, and firms raise the wage rate to attract more workers
Price level rises, real GDP decreases
Economic growth results from a growing labor force and more productivity, increasing potential GDP
Inflation results from a growing quantity of money that outpaces the growth of potential GDP
Economic growth comes to increase potential GDP(rightward shift in the vertical line)
Inflation arises from aggregate demand increasing faster than potential GDP
Real Business Cycle results from fluctuations in AS and AD
AS fluctuates because of labor productivity, changing the growth rate of potential GDP
AD fluctuations are the main source of the business cycle, because it fluctuates more than AS
Inflation also has cycles; Demand Pull and Cost-Push
Inflation that starts because of AD increasing is demand-pull inflation
Factors that increase aggregate demand lead to inflation(C+I+G+Nx), but what sustains it is a growth in the quantity of money
When quantity of money increases, AD moves to the right
When GDPr exceeds potential GDP,the money wage rate has to rises and AS move lefts
Inflation that is a result of AS increasing is cost-push inflation(or stagflation)
Factors that shift AS(productivity, input prices, expectations of inflation, government regulation)
Sustained by growth in the quantity of money
Higher input costs decrease AS, while AD doesn’t change
When costs increase, AS curve shifts left
When GDPr is below potential GDP, the Fed increases Q of M and AD goes right
Marginal Propensity(behavior) to Consume
Can only save or spend a dollar
Aggregate expenditure is C+I+G+NX
Aggregate planned expenditure is the planned expenditure for each sector
Equal to autonomous expenditure + induced expenditure
The sum of spending plans for households, firms, governments
Autonomous expenditure is the components of aggregate expenditure that don’t change when real GDP changes
(I+G+X)(unimportant)
Investment + government expenditure + exports + components of consumption expenditure and imports not influenced by real GDP
Induced expenditure is the parts of aggregate expenditure that change when real GDP changes
(consumption-imports)(unimportant)
Consumption function is the relationship between consumption expenditure and disposable income
Disposable income = aggregate income(GDP)- net taxes
Net taxes are taxes paid to the government - transfer payments
SAVE OR SPEND
Graph on slides to look at
Marginal propensity to consume is the fraction of a change in disposable income spent on consumption
Richer people have a lower mpc to consume since they have more money to save
***
Must be less than or equal to 1
Helps us find the effect of spending
MPS is marginal propensity to save
Real Interest Rate and Wealth/Expected Future Income influence consumption plans(fall and rise together)
Equilibrium Expenditure
The multiplier is the amount by which a change in any component of autonomous expenditure is magnified or multiplied to determine the change that it generates equilibrium expenditure and real GDP
Aggregate Expenditure Multiplier
Increase in investment increases aggregate expenditure because it causes an increase in consumption expenditure
Multiplier determines how much aggregate expenditure increases because of another component of autonomous expenditure
Determines change in equilibrium expenditure
Multiplier = Change in equilibrium expenditure/Change in autonomous expenditure
Multiplier size depends on MPC
Higher MPC = Higher Multiplier
1/1-MPC is the mpc multiplier; also 1/MPS
Taxes decrease the multiplier, along with imports(only US expenditure affects real GDP)
Tax Multiplier = MPC Multiplier - 1
Multiplier gives momentum to the economy’s new direction
Expansion caused by increase in autonomous expenditure
Firm inventory decreases so they produce more and increase Real GDP
Test 4
Financial capital- funds firms use to buy and operate physical capital
Gross investment- total amount spent on new capital
Net investment- gross investment minus depreciation
Wealth- the value of all the things that a person owns(not earning)
Saving- the amount of income that is not paid in taxes or spent on consumption; added to wealth
Saving is the source of funds that finance investments
Loan Market:
Businesses use loans to buy things and give credit to their customers
Households purchase more expensive items with loans
Bond Market:
Bond- promise to pay a certain amount of money at a certain date; used by governments to raise money
Stock Market:
Stock- ownership to profits that firm makes
A financial institution is a firm that operates on both sides of the market for financial capital; borrows and lends
Investment banks- sell and give bonds to raise money for firms and governments
Commercial banks
Government sponsored mortgage lenders- government related that buys from banks
Pension funds- used to buy stocks and bonds
Insurance companies- firms that provide compensation in accidents
Net worth is the total market value of lent-minus
A positive net worth means the institution is solvent and can keep trading
Institutions lend and borrow
Negative means the institution is insolvent and has to stop trading
The owners of an insolvent institution suffer
A firm is illiquid if it makes long term loans with borrowed funds and needs to repay more of what was borrowed than what they have available
Can save themselves by borrowing from others
Stocks, bonds, and loans are financial assets
An interest rate is a percentage of the price of the asset
When asset price rises, interest rate falls, and vice versa
Markets and institutions allow us to
Invest in capital
Smooth Consumption Expenditures
Trade Risk
Loanable Funds
Interest rates are the price of borrowing and using money
Nominal is regular; real is adjusted for inflation
Nominal interest rate = real interest rate + expected inflation
Real interest rate = nominal interest rate- expected inflation
For loanable funds we use real interest rates
Loanable funds are funds available for borrowing or lending come from the federal reserve
Commercial banks go to fed banks to get loanable funds
Savings->deposits->loans-> lent out
Qlf = Quantity of loanable funds
Households and business demand loanable funds for consumption/investment
Although banks hold money technically we are supplying loanable funds
The demand for loanable funds is the quantity of credit wanted and needed at every real interest rate by borrowers in an economy to finance investment
High interest rates restrict how much you can borrow
We use one average interest rate called THE interest rate
Loanable funds are used for investment by businesses, private loans, government budges, and international investment/lending
Investment depends on interest rate and expected profit
Firms only invest when they expect to earn a rate of profit that exceeds the real interest rate
When interest rate rises, less profit; when IR falls, more profit
Higher IR = smaller QLF; Smaller IR = higher QLF
Different influences on expected profit can be categorized into objective(business cycle, tech change, population growth), subjective(Keynes animal spirits), and the Contagion effect
Influences of demand for loanable funds
Decrease in expected profits shifts demand curve to the left
Supply of loanable funds; quantity of credit provided at every real IR by lenders in an economy
The quantity of loanable funds supplied is the total funds available from private saving, the gov’t budget surplus, and international borrowing during a given period
Saving is the main of supply of loanable funds
Depends on:
Real Interest Rate
Disposable Income (higher DI greater the MPS)
Wealth (greater the wealth the less it will save) ***
Expected Future Income (higher EFI the less it saves today)
Default Risk (greater risk = higher IR = smaller supply of LF)
More saving = More supply of loanable funds
Higher RIR, greater QLF; lower RIR, smaller QLF
Supply is shifted by
Decrease is disposable income, moves left
Wealth, expected future income, default risk increases
When demand for loanable funds increases, IR rises
When supply of loanable funds increases, IR falls
When govt increases deficit spending, it increases demand OR decreases supply
Real IR increases either way
Government in Loanable Funds Market
Actions that change the gov’ts budget balance influences loanable funds and real interest rate
A government budget surplus increase supply of loanable funds
Government budget surplus is added to private saving supply
An increase in the supply of loanable funds brings a lower RIR which decreases the quantity of private saving and increases the quantity of investment and quantity of loanable funds demanded
Government budget deficit increase the demand for loanable funds
Increase of demand raises RIR, increases the quantity of private saving
Higher interest rate decreases investment and the quantity of loanable funds demanded
A budget deficit causes investment to crowd out; can’t profit anymore
The tendency for a government budget deficit to raise the RIR and decrease investment is the crowding-out effect.
The Ricardo Barro Effect suggests that a government budget deficit has no effect on the RIR or investment
Works when private saving and supply of loanable funds increases to offset government budget deficit
Supply of loanable funds increases by an amount equal to the government budget deficit
Essentially stops crowding out
Basically anything can be used as money
Money is a commodity or token used as a means of payment for goods and services
Can be recognized and divided into smaller parts
Used to buy anything
Means of payment is a way to settle a debt
MONEY IS NOT A LOAN. MONEY IS USED TO PAYOFF A LOAN
Money acts as a medium of exchange, a unit of account, or a store of value
A medium of exchange is an object that is accepted in return for goods/services
Before money goods and services were directly traded for other goods and services; this is known as bartering
Bartering needs a double coincidence of wants. Money allows specialization in comparative advantage
A unit of account is an agreed upon measure for stating the prices of goods and services; opportunity costs of purchases
Store of value is any commodity or token that can be held and exchanged for goods or services
The more stable the value of a commodity/token, the better it is as a store of value or money
Values increase over time
Inflation decreases the money’s store of value
Money in the world today is called fiat money
Fiat money is objects that are money because the law makes them money
This group includes currency, deposits at bank
CURRENCY INSIDE BANKS IS NOT MONEY; would be like double counting it
M0 = Currency and bank reserves
M1 is currency by individuals and businesses, traveler’s checks, checkable deposits owned by individuals and businesses
M2 is M1 plus all types of deposits and money market funds
Something is considered money if it accepted as a means of payment
M1 is money, but some deposits aren’t a means a payment
Some of the deposits in M2 are payment
Checks, credit cards(loans), debit cards, mobile wallets are NOT money
E-Currency will be money at some point
E-cash is the electronic version of paper notes and coins; electric currency and a form of money
Money tends to lose value over time
Money today > money tomorrow
Future value of money = X * (1+r)
Federal Reserve is at the top of the banking system
Banks and other institutions are under it that take deposits and provide services that enable people and businesses to make payments
Reserves regulate how commercial banks and other institutions work
A commercial bank is a firm licensed by the comptroller of currency in U.S. Treasury to accept deposits and make loans
Mergers decrease amount of banks
A commercial bank accepts checkable deposits, savings deposits, and time deposits
Banks want to maximize the long-term wealth of stockholders
Banks borrow from depositors and others and lend for long-term at high interest rates
Lending is risky, banks have to be prudent in how they use their depositor’s funds and balance security of returns
When banks make losses, a bank run(everyone trying to get their money) will cause a crisis
A bank divides its assets into reserves, liquid assets, securities, and loans
A bank’s reserves consist of currency in bank vaults + the balance on its reserve account
Currency in vault for depositors
The required reserve ratio is the minimum percentage that the fed requires banks to hold as reserves; 10% in this class
Reserve is like bank deposit to fed; fed is bank for a bank
Desired reserves can > required reserves when cost of borrowing reserves is high
Banks create money by making loans
Liquid assets are short term treasury bills and overnight loans to other banks
When banks have excess reserves they can lend them to other banks
The interbank loans market is called federal funds market and the interest rate on those loans is the federal funds rate
Fed policies attempt to target the federal funds rate
Securities are bonds issued by the U.S. government to banks
A bank earns an interest rate on securities but sell them quickly if it needs cash
Loans are the funds that banks provide to businesses and individuals and include outstanding credit card balances
Loans earn the bank a high interest rate, but they are risky and cannot be called in before the agreed date
Three types of thrift institutions are savings/loans associations, saving banks, and credit union
S&L is a financial institution that accepts checkable and savings deposits and makes personal, commercial, ad home purchase loans
A savings bank is financial institution that accepts saving deposits and mainly makes consumer and home-purchase loans
A credit union is a financial institution owned by a social/economic group such as a firm’s employees, that accepts saving deposits and makes mostly consumer loans
Thrift institutions hold reserves and must meet minimum reserve ratios
A money market fund is a financial institution that obtains funds by selling shares and uses these funds to buy assets such as U.S. Treasury Bills
Money market fund shares act like bank deposits
Shareholders write checks on money market fund accounts
Money multiplier can be applied to the reserve ratio; Multiplier = 1/reserve ratio
The initial deposit doesn't count for the new money produced however; was already in the money supply
Initial is subtracted from the new money produced
Federal Reserve System
The fed is the central bank of the U.S.
The central bank is a public authority that provides banking services to banks and regulates financial institutions/markets
The fed regulates the interest rate and the quantity of money to keep inflation low and sustained economic growth
12 Federal districts; each district has its own bank
Elements of the fed:
Chair of the Board of Governors
Chair is chief executive, public face, and center of power/responsibility
Board of Governors
7 members appointed by the POTUS confirmed by the Senate for 14 year terms
One board member as chair for 4 years
Regional Federal Reserve Banks
Each bank has 9 directors, 3 appointed by the Board of Governors and six elected by the commercial banks
Federal Open Market Committee
Fed’s main policy-making committee
Consists of chair, member of board of governors, president of the federal reserve bank of NY, four presidents of the other Fed Reserve Banks
Meet every six weeks
Fed has 4 main policy tools
Required reserve ratios
Banks holding a minimum percentage of deposits as reserves
DIscount rate- the interest rate at which the fed is ready to lend reserves to commercial banks
A change in the discount rate begins with a proposal to the FOMC by a reserve bank
When the FOMC agrees on a change, it proposes it to the Board of Governors
An open market operation is the purchase or sale of government securities- Treasury bills and bonds, by the New York Fed in the open market
Purchase allows banks to make more loans
Sales make it harder for banks to make loans
Extraordinary crisis measure- new tools to deal with collapses(Quantitative easing, credit easing, operation twist)
Quantitative easing is the fed creating bank reserves by conducting large scale open market purchases at a low federal funds rate; can involve buying private securities
Pumping a lot of money at once into the economy
Credit easing- the fed buying private securities or makes loans to financial institutions to stimulate lending
Operation Twist- when the fed buys long term govt securities to sell short term govt securities; lowering long term interest rates to stimulate borrowing and investment
The Fed’s normal policy tools change either the demand or supply of monetary base, which change the interest rate
Monetary base is the sum of coins, fed notes, and banks’ reserves at the Fed; the larger the monetary base, the greater the quantity of money it can support(shrinks the multiplier)
Increasing the reserve ratio, the discount rate, or selling securities lead to an increase in the interest rate
Decreasing the reserve ratio, lowering the discount rate, and purchasing securities in the open market decrease the interest rate
The amount of deposits that banks can create is limited by the monetary base, desired reserves, and desired currency holding
The monetary base is the sum of Federal Reserve notes, coins, and bank deposits at the Fed
The size of the monetary base limits the total quantity of money that the banking system can create due to desired reserves and desired currency holdings
Both depend on the quantity of money
Open market operations are used to increase the monetary base
The desired reserve ratio is the ratio of reserves to deposits that a bank wants to hold; exceeds the required reserve ratio by the amount the bank needs to be prudent
Excess reserves = actual reserves- desired reserves
When the quantity of money increases, so does the quantity of currency people want to hold
Desired currency holding increases when deposits increase; currency leaves banks when they make loans and increase deposits
The leakage of currency is called the currency drain; the ratio of currency to deposits is called the currency drain ratio
An open market operation is the purchase/sale of government securities by the Fed to influence the quantity of money
Basically printing money
When the fed buys securities in an open market operation, it pays for them with newly created bank reserves and money
When there are more reserves in banking systems, the supply on interbank loans increases, the demand for interbank loans decreases, and the federal fund rate(interest rate on loans in the interbank market) decreases
When the fed sells securities it is bought with bank reserves and money, decreasing the money supply
The Fed sets a target for the interest rate and using OMO to reach the target
When reserves increase, lending increases, increasing quantity of money
When reserves decrease, lending decreases, decreasing quantity of money
When the fed sells securities, their assets decrease by 100m, the reserves of the banking system decrease by 100m, and banks borrow in the market to meet their desired reserve ratio
An open market purchase increases bank reserves that increase the monetary base, and the increase equals the amount of the purchase
Quantity of bank reserves increases and gives banks more reserves to lend
Multiplier = 1/Reserve Ratio
Ratio of change in quantity of money to change in monetary base
Currency drain ratio: Ratio of C(Currency) to D(Deposits)
MB=(Reserves(R) + Currency(C))
Quantity of money = Deposits + Currency(D+C)
Make sure when it is a DEPOSIT you use the multiplier and subtract the initial deposit from it
Buy increases money supply, sell decrease
Real factors that are independent of the price level determine potential GDP and NRU
Investment demand and saving supply determine a RIR, population growth, human capital growth, and technological change
Money consists of currency and bank deposits
Banks create money, FEd influences QOM, determining monetary base and FFR
The effects of the Fed’s actions on the short term nominal interest rate and the long run effects of the Fed’s action are involved in the effects of money
QOM demanded is the amount of money that households and firms choose to hold
Price of money
Value of money is the value of goods and services it can buy; opportunity cost is the goods and services forgone by holding this
The benefit of holding money is the ability to make payments; more money held, the more you can buy and the higher the benefit of holding money
The opportunity cost of holding money is the interest forgone on an alternative asset; holding money instead of putting in a fund with an interest rate costs the rate multiplied by the money being held
The higher the OC of holding money, the lower the demand for money
Nominal interest is the opportunity cost of holding money; equal to RIR + expected inflation rate
RIR = Nominal IR- Inflation Rate
The higher the nominal interest rate, the smaller the quantity of money
The demand for money is the relationship between QOM demanded and the nominal interest rate
The lower the NIR, the greater the quantity of money demanded
A rise in NIR decreases quantity of real money demanded
A fall increases the quantity of money demanded
The price level- A rise in the price level brings an increase in the same amount of the quantity of money that people plan to hold because number of dollars that need to be made is proportional to price level
Real GDP; demand for money increase as real GDP increases
Increase in interest rate increases demand for money; allows people to earn more interest
Financial technology can increase the demand for money; things like transfers, ATMS, deposits, and debit cards make money easier to use
Credit cards make it easier to buy goods and services on credit
The supply of money is the relationship between the quantity of money supplied and the nominal interest rate
The quantity of money supplied is determined by what the banking system and Fed does
Money supply curve is vertical due to the quantity of money being fixed
The nominal interest rate makes the QOM demanded = QOM supplied
When bonds are bought, interest rate falls, and QOM demanded increases
When bonds are sold, interest rate rises, and QOM demanded decreases
Interest rate and bond prices move in opposite directions
When the government issues a bond, it specifies how much interest it pays each year
Bond interest rate = Dollar amount received/bond price
When IR is above equilibrium level, quantity of money supplied exceeds quantity of money demanded
People hold too much money and interest rate needs to be lowered
When IR is below, vice versa
Fed changes QOM to change the interest rate
Increase causes interest rate to fall and supply to increase; Decrease causes interest rate to rise and supply to decrease
A change in the nominal interest rate affects borrowing and lending, investment, consumption, and spending, which affects real GDP and price level
The long run refers to the economy at full employment or when we smooth out the effects of the business cycle
When real GDP = potential GDP there is full employment, and real GDP = potential in the long run
In the short run, the interest rate adjusts to make QOM demanded = QOM supplied
Price level does the adjusting
The equilibrium in the loanable funds market determines the real interest rate in the long run
An economy with no inflation has the same NIR and RIR
The interest rate is determined by real forces in the long run
The variable that adjusts in the long run is the price of money
Law of demand applies to money; lower the price/value of money, the more money people want to hold
Value of money= 1/P
P is the price level, or the GDP price index divided by 100
The value of money is the quantity of goods and services that a unit of money will buy
When the price level increases the value of money decreases
Money market equilibrium determines long run value of money
When QOM > the long run quantity demanded, excess money can be spent
Value of money falls and prices go up
When it is less, people lower spending to increase the quantity of money they hold
PL falls and the value of money rises
When supply = demand, we are at equilibrium
Long run demand for money is determined by potential GDP and equilibrium interest rate
LRMD curve shows how the quantity of money households and firms plan to hold changes depending on the value of money
MS curve shos QOM supplied, and the price level adjusts to make the value of money = 1 and achieve long term equilibrium
When the Fed increases the quantity of money by 10%, the quantity of money lowers the IR and people want to spend more
When real GDP = potential GDP, prices start to rise
A new equilibrium is reached where PL increases at the same rate as QOM
Quantity theory of money: when real Gdp = potential GDP, an increase in the quantity of money brings an increase in the price level
Money growth brings inflation
QTM = Price level and money supply are proportional
Velocity of circulation- number of times in a year that the average dollar of money gets used to buy final goods and services
Equation of exchange: equation stating the quantity of money multiplied by velocity of circulation = price level * real GDP
M*V = P* Y
P*Y is equal to nominal GDP
With this formula, we can also rearrange to get P = (M*V)/Y
Money supply, velocity and real GDP influence the price level
If M increase P also increases
Money growth + velocity growth = inflation rate + Real GDP growth
Inflation rate = Money growth + velocity growth - real GDP growth
Inflation rate increases slowly and temporarily increases the real GDP growth rate
Velocity speeds up as IR increases
Faster inflation rate reduces potential GDP and slows real GDP growth
Money growth rate works in the opposite way
In the long run and other things remaining the same, a change in the growth rate of the quantity of money brings an equal change in the inflation rate
Hyperinflation is when the inflation rate exceeds 50% a month; happens when money grows massively
Inflation is costly
Tax costs- government gets revenue from inflation, and inflation is a tax
The income tax of nominal interest rates separates before tax interest and after tax interest rate
Fall in after tax rate weakens incentive to save and lend
RIse in before tax rate weakens incentive to borrow and invest
Inflation increases the nominal interest rate, and because income taxes are paid, the true income tax rate rises with inflation
Higher inflation rate = higher true income tax rate
Higher tax rate = higher interest rate paid by borrowers
With a fall in saving and investment, GDP growth slows
Shoe leather costs arise from an increase in the velocity of circulation of money and an increase in the amount of running around that people do to try avoiding losses
When money loses value at a rapid anticipated rate it is not a good store of value
Incomes are paid and spent immediately
Money is our measure of value; we make decisions based on the marginal benefits and costs
Borrowers and lenders agree on the terms of money
Inflation make the value of money changes and messes up the measure of value
Leads to confusion
A high inflation rate leads to uncertainty about the long-term inflation rate
Uncertainty makes it difficult to plan for the long-term and reduces investment and slows economic growth
People want to avoid the losses from inflation
Gains and losses happen because of unpredictable changes in the value of money
No specialization
Cost of inflation depends on the rate and predictability
Higher inflation and more unpredictable = greater cost
Reserve market
Banks dont actually hold reserves
After 2008 they started holding more reserves; ample reserves given to the fed for earning interest
Weird graph
Federal budget is annual statement of the tax revenues, outlays, and the surplus/deficit of the U.S. government
Finances the activities of the federal government and achieves macroeconomic objectives
Fiscal policy is the use of the federal budget to acheive the macroecnomic objectives of high and sustained economic growth and full employment
President and Congrss decide budget and develop fiscal policy annually
Fiscal year begins on October 1 and ends September 30
Budget balance = tax revenues- outlays(or revenue- spending)
Balanced budget is 0
Surplus is positive, deficit is negative
Government borrows to finance a deficit and repays debt for a surplus
The outstanding debt that rises from past budget deficits is national debt
Debt at end of year = Debt at end of previous year + Budget deficit of current yar
Tax revenues consists of personal income taxes(big)(taxes paid on wages, salaries, and interest), Social Security taxes(taxes paid by workers and employers to fund SS benefits), corporate income taxes(small)(paid by corporations on their profits), and indirect taxes; sales, customs, excises
Us has been piling debt for past 40 years and will continue to
Age distribution is a big part
Social Security obligations are adding up to the debt
Fiscal imbalance; the present value of the government’s commitments to pay future benefits minus the present value of its future tax revenues
A present value is an amount of money that will earn interest to grow and equal a required future amount
Basically true debt of gov’t
To meet these obligations, the government can choose any combination of raising income taxes, raising social security taxes, cutting social security benefits, and cutting other federal government spending
A fiscal imbalance has to be corrected at some point
Generational imbalance is the division of the fiscal imbalance between the current and future generations
Current generation is before 1988; future is after
Classical, keynesian, monetarist macroeconomic
The theories of these people have had flaws exposed
Problems in Keynesian economics
Fiscal policy changes outlays or tax revenues due to government spending
A change in any item in gov’t budget changes aggregate demand
Reponse to the state of the economy or a result of new spending/tax decisions by Congress
Automatic fiscal policy- fiscal policy action initiated by the economy
Discretionary fiscal policy- fiscal policy action initiated by an act of Congress
Automatic fiscal policy is a consequence of tax revenues and outlays fluctuating with real GDP
Automatic stabilizers stablize real GDP
Induced taxes; taxes that vary with real GDP; more real Gdp = more tax revenue
Needs-tested spending is spending on programs that entitle suitably qualified people and businesses to receive benefits; benefits that vary with need and with the state of the economy(like unemployment)
Both of these decrease the multiplier effects of change in autonomous expenditure and moderate both expansions and recessions make real GDP more stable
An automatic stimulus happens when government tax revenues fall and outlays increase in a recession; budget provides automatic stimulus that shrinks the gap
And vice versa
Fluctuations in the government budget balance over the business cycle create a need to distinguish between cyclical and structural balance
Recession: Revenue down, spending up
Peak: Revenue up, spending down
A structural surplus/deficit is the budget balance occurring if the economy was at full employment
A cyclical surplus/deficit is the budget balance that arises because tax revenues and outlays are not at full employment levels
Structure balance + cyclical balance = budget balance
Discretionary fiscal policy can take the form of a change in outlays or tax revenue
A change in any items in the government budget changes aggregate demand with a multiplier effect
Gov’t expenditure multiplier is the effect of a change in government expenditure on g&s on aggregate demand
Increase in aggregate expenditure increases aggregate demand and increases real GDp and increases consumption expenditure, increasing aggregate demand more
The tax multiplier is the effect of a change in taxes on aggregate demand
Decrease in taxes increases disposable income increases c and aggregate demand, making employment and real GDP increase; consumption continues to decrease
Spending multiplier - 1
Both increase aggregate demand with a multiplier effect
The transfer payment multiplier is the effect of a change in transfer payments on aggregate demand
Multiplier is like tax multiplier opposite direction
An increase in transfer payments increases disposable income, increases consumption expenditure
Employment and real GDP increase and consumption increases more
Balanced budget multiplier is the effect on aggregate demand of a simultaneous change in government expenditure and taxes that leave the budget balance unchanged
Budget is positive
The government can pursue a fiscal stimulus by increasing government expenditure on goods and services(buying new equipment, building roads, bombing the midle east), increasng transfer payments(more robust social services or welfare), cutting taxes(lowering taxes, eliminated taxes, reducing income generators)
Combining all 3
Fiscal stimulus is limited by the amount of time it takes Congress to pass laws
Most of the federal budget can’t be used for discretional fiscal policy
Estimating potential GDP is difficult
Econoic forecasting; some policies need time to be effective
Contractionary is for inflation, expansionary is for recession
