Unit 5

Disinflation: Reduction in the inflation rate from year to year which can be seen in the LRPS. this also occurs when AD declines.

Deflation: General decline in PL

Hyperinflation: when the economy experiences unusual high rise of inflation.

Adverse supply shock- SRPC intersect LRPC 

Supply side economics also known as (Reaganomics) Triple balance effect. (lower taxes and decrease regulation) (lower taxes and provide positive work incentives and thus shift the AD curv to the right)

Changes in AS, not AD. Determines the level of inflation unemployment rates and economic growth. 

The laffer curve: theoretical relationship between tax rates and government revenue. As rate increases from 0 tax revenue increases from 0 to some maximum level, then declines. 

3 criticism:
1. evidence suggests that the impact of tax rates on incentives to work, save and invest are small.
2. Tax cut also increase demand, which can fuel inflation
3. where the economy is actually located on the curve is difficult to determine.

Phillips Curve
Inverse relationship between unemployment and inflation
Long Run Phillips Curve
Misery Index- the combination of inflation and unemployment in any given year.

Single digit misery is good.

Unit 7; Balance of Payments, Foreign Exchange, Comparative and Absolute Advantage

Topic 1- Balance of Payment 

Balance Payment

  • measure of money inflows and outflows between the United States and the rest of the world. 
  • Inflows: Credits
  • Outflows: Debits
  • The Balance of Payments is divided into three accounts:
  1. Current Account
  2. Capital/Financial Account
  3. Official Reserves
  • Every transaction in the Balance of Payment is recorded twice. 
  • current account has to equal to capital account
Current Account
  • net exports 
    • known as balance of trades
    • exports - imports
  • net foreign factor payment
    • income earned by US earned foreign assets
  • net transfers
    • tend to be unilateral (one-way)
    • what do we give to other countries/what do they give to us
    • es. foreign aid 
Capital/Financial Account
  • the balance of capital ownership
  • includes the purchase of both real and financial assets 
  • direct investment in the US is a credit to the capital account
    • ex. Toyota factory in San Antonio
  • direct investment by US firms/individuals in a foreign country are debits to the capital account.
    • ex. dell computer factory in Costa Rica
  • the purchase of foreign financial assets represents a debit to the capital account
    • ex. bill gates buying stocks in petro china
  • purchase of domestic financial assets by foreigners represents a credit to the capital account.
    • ex. cuba purchases a large stake in mcdonalds
  • capital and current account, when added together, must zero each other out. 
Official Reserves
  • the foreign currency holdings of the United States Federal Reserve System. 
  • the official reserves zero out the balance of payments 
Formulas for Balance of Payments
  • Balance of Trade= goods export + goods imports
  • Balance on Goods and Services= goods exports + services exports - goods imports + services imports
  • Balance of Current Amount= net exports + net foreign factor payment + net transfer
  • Capital amount= foreign ourchases of assets + US purchases of foreign assets

Topic 2- Foreign Exchange

Foreign Exchange Market- The buying and selling of currency


appreciationthe increase of value of a countries currency with respect to a foreign countries currency 

  • a dollar is set to be stronger
  • less unit of dollars that are needed to buy a single unit of the other currency
  • trade deflict 

depreciation: the loss of value of a countries currency with respect to a foreign currency

  • the dollar is consider weak
  • more units of dollar is needed to buy a single unit of the other currency

Topic 3- Comparative and Absolute Advantage

Absolute Advantage- the producer can produce the most output or requires the least amount of input (resources)

  • Ex. Papa Johns produces 12 pizzas while McDonald produces 3  

Comparative Advantage- the producer with the lowest opportunity cost

  • Lowest number when you do the calculations. 
  • Lowest opportunity cost

Input vs. Output 

Input- certain amount of input to get a given product (time)
Output- certain amount of product out of a given input (production)

Unit 4- Topic 1- Money

Three Uses of Money

  1. Median of Exchange (barter)
  2. Unit of Account (economic value)
  3. Store of Value (money's value over time)

Types Of Money

  1. Commodity Money (Gold Silver)
  2. Representative Money (IOU's) ( ex. chicken could be representative money, but has no value.)
  3. Fiat Money (money because the government says so)

Characteristics of Money

  1. Durability (withstand physical wear and tear)
  2. Portability (carry/transfer)
  3. Divisibility (divided into small increments)
  4. Uniformity (same/identical)
  5. Acceptability (cash is accepted)

Money Supply

  • M1 Money
    • cash
    • currency
    • coins
    • checkable/demand deposits (checking account)
  • M2 Money
    • encompasses M1 money + saving account
  • M3 Money
    • M2 + money market account + CD
    • liquidity (easy to convert to cash)

Balance Sheet- # summarizes the financial position of a bank at a certain time.

Liabilities VS. Assets 

Liabilities

  • OWE
  • 1. RR- Required Reserve- the % of demand deposits that must be held in the vault.
  • 2. ER- Excess Reserve- source of new loans
  • 3. Property (building/fixtures)- value of bank's property
  • 4. Security and Bonds- bonds that are previously purchased by the banks new bonds sold to the bank by the federal reserve these bonds can be purchased from the bank and into cash and immediately becomes available as excess reserve.
  • 5. Loans

Assets

  • OWN
  • Net Worth of Owner's Equality
  • DD- Demand Deposit- cash deposit from the public

Liabilities =Assets 

RR+ER=DD

Liabilities                             Assets
RR (Required reserves)          DD (Demand/ Chekable Deposits) 
ER (Excess Reserves)

In order for money supply to increase, federal government must buy bonds, loans. To decrease money supply, they sell bonds or loans
  • Federal Revenue Banking System: Federal government holds a fraction of the deposits back as a reserve in the bank. 

Fractional Reserve Banking System

  • Banks hold fraction of deposit back as a reserve in a bank.
  • Vote Cash- money that is kept back

Money Market- It is the market where the fed and the user's of money interact thus determining the nominal interest rate.

  • Money Demand (MD)- comes from households, firms, government, and the foreign sector 
  • Money Supply (MS)- is determined by the federal reserve. 
  • Transaction Demand: demand for money as a medium or exchange 
  • Asset Demand: demand for money as a store of value.
  • Depended upon interest rate
Total Money Demand
  • MD Is downward sloping because at high interest rates, people are less inclined to hold money and more inclined to hold stocks and bonds. 
  • Money supply is determined by the Fed because they have control over the supply of money 
  • Money supply is vertical because it is independent of the interest rate 
Contractionary Monetary Policy
  • interest rate increases 
  • Money Supply (MS) shifts to the left
  • Reserve ratio↑
  • Discount rate↑
  • SELL BONDS (less money) (MS ↓)
Expansionary Monetary Policy: 
  • interest rate decreases
  • MS shifts to the right
  • Reserve ratio↓
  • Discount rate ↓
  • BUY BONDS (more money) (MS ↑
Open Market Operations: The government will either sell or buy bonds based on the situation.
Federal Funds Rate: Proportion of the money required to save as reserve. (bank to bank loan)
Discount Rate: money banks borrow from the FEDS
Monetary Multiplier: 1/RR

Loanable Funds 
the market where buyers and savers meet to exchange funds at the real interest rate both the demand supply for loan-able funds comes from households, firms, the government, and the foreign sector.

Unit 3- Topic 6: Fiscal Policy

What is Fiscal Policy? Changes in the expenditures or tax revenues of the federal government.

2 Tools of Fiscal Policy

  • Taxes: Government can increase or decrease taxes
  • Spending: Government can increase or decrease spending
  • TAX ↑ SPEND ↓
  • TAX ↓ SPEND ↓
Fiscal Policy is enacted to promote our nations economic goals: full employment, price stability, and economic growth.
Deficit, Surplus, Debt
  • Balanced Budget- Revenues = Expenditures
  • Budget Deflict- Revenues < Expenditures
  • Budget Surplus- Revenues > Expenditures
  • Government Debt-  (Sum of all deficits- sum of all surplus)
Government must borrow money when it runs into budget deflict
Government borrows from;
  • Individuals
  • Corporations
  • Financial Institution (Banks)
  • Foreign cities/ governments
Fiscal Policy; Two Option

Discretionary Fiscal Policy (action)

  • Expansionary Fiscal Policy- think deflict
  • Contractionary Fiscal Policy- think surplus
  • Non Discretionary Policy- no action 
Discretionary (Governmental action)
Increasing or decreasing government spending and/ or taxes in order to return the economy to full employment. Discretionary policy involves policy makers doing fiscal policy in response to an economic problem.

Automatic (No government action)
Unemployment compensation and marginal tax rates are examples of automatic policies that helps mitigate the effects recession and inflation. Automatic Fiscal Policy takes place without policy makers having respond to current economic problems.

Contractionary Fiscal Policy- policy designed to decrease aggregate demand; strategy for controlling inflation

  • Inflation is countered with contractionary policy
  • Decrease government spending (G↓)
  • Increase Taxes (T↑)

Expansionary Fiscal Policy- policy designed to increase aggregated demand; strategy for increasing GDP, combating a recession and reducing unemployment.

  • Recession is countered with expansionary policy. 
  • Increase government spending (G↑)
  • Decrease taxes (T↓)

Automatic or Built- in stabilizer

  • Anything that increase the government's budget deficit during a recession and increases its budget surplus during inflation WITHOUT REQUIRING EXPLICIT ACTION BY POLICY MAKERS

What Counts As a Transfer Payments?

  1. Welfare Checks
  2. Food Stamps
  3. Unemployment Checks
  4. Corporate Dividends
  5. Social Security
  6. Veteran's Benefits
  • Progressive Tax System- Average tax rate RISES with GDP
  • Proportional Tax System- Average tax rate remains CONSTANT with GDP
  • Regressive Tax System- Average tax rate FALLS with GDP

Average tax rate (tax revenue/ GDP) 

Unit 3: Topic 5- Consumption and Savings

Disposable Income (DI)

  • Money (Income) after taxes or net income
  • Can actually spend
  • DI = Gross Income- - Taxes
  • Gross means TOTAL

2 Choices When It Comes To DI

With disposable income, households can either
      1. Consume (spend money on goods and services)
      2. Save (not spend money on goods and services)

Consumption

  • Household spending
The ability to consume is constrained by 
  • The amount of disposable income
  • the propensity to save
Do household consume if DI = 0?
  • Autonomous Consumption
  • Dissaving

Saving

  • Household NOT spending
The ability to save is constrained by
  • The amount of disposable income
  • The propensity to consume
Do households save if DI = 0?
  • NO

APC AND APS

Average Propensity to Consume (APC)
Average Propensity to Save (APS)
  • APC + APS = 1
  • 1 - APC = APS 
  • 1 - APS = APC 
  • APC > 1 = DISSAVING
  • -APC = DISSAVING

Marginal Propensity to Consume AND Marginal Propensity to Consume

Marginal Propensity to Consume (MPC)
๐Ÿ”บC/๐Ÿ”บDI
(C- Consumption)
% of every extrar dollar earned that is spent
Marginal Propensity to Save (MPS)
๐Ÿ”บS/๐Ÿ”บDI
(S- Saving)
% of every extra dollar earned that is saved
MPC + MPS = 1
1 - MPC = MPS
1 - MPS = MPC

The Spending Multiplier Effect 

  • An initial change in spending (C, Ig, G, Xn) causes a larger change in aggregate spending or Aggregate Demand (AD)
  • Multiplier = ๐Ÿ”บ in AD/ ๐Ÿ”บ in spending
  • Multiplier = ๐Ÿ”บ in AD / ๐Ÿ”บ (C, Ig, G, Xn)
Why does this happen? 
  • Expenditures and income flow continuously which sets off a spending increase in the economy.

Calculating the Spending Multiplier 

  • The Spending Multiplier can be calculated from the MPC or the MPS.
  • Multiplier = 1/1 - MPC or 1/ MPS
  • Multipliers are (+) when there is an increase in spending and (-) when there is a decrease in spending.

Calculating the Tax Multiplier 

  • When the government taxes, the multiplier works in reverse.
  • Why? Because now money is leaving the circular flow
  • Always NEGATIVE
  • Tax Multiplier (note it is negative) = -MPC/ 1- MPC or -MPC / MPS
  • If there is a tax - cut, then the multiplier is + because there is now more money in the circular flow.

Unit 3- Topic 4: Interest Rates and Investment Demand

What is Investment? 

Money spent or expenditures on:

  • New plants (factories)
  • Capital Equipment (machinery)
  • Technology (hardware and software)
  • New Homes (homes built that year)
  • Inventories (goods sold by producers)

Expected Rates of Return


How does business make investment decision?

  • Cost/ Benefit Analysis
How does business determine the benefits?

  • Expected rate of return
How does business count the cost?

  • Interest costs
How does business determine the amount of investment they undertake?

  • Compare expected rate of return to interest cost
  • If expected return > interest cost, then invest
  • If expected return < interest cost, then do not invest
What then, determines the cost of an investment decision?

  • The real interest rate (r%)

Investment Demand Curve (ID)

What is the shape of the investment demand curve?
  • Downward sloping
WHY?
  • When interest rates are high, fewer investments are profitable; when interest rates are low, more investments are profitable.
  • Conversely, there are few investments that yield high rates of return and many yield low rates.  

Unit 3- Topic 3: The AS/AD Model

The AS/AD Model- The equilibrium of AS & AD determines current output (GDPR) and the price level (PL)


Full Employment- Full Employment equilibrium exists where AD intersects SRAS & LRAS at the same point.
Recessionary Gap- A recessionary gap exists when equilibrium occurs below full employment output.
Inflationary Gap- an inflationary gap exists when equilibrium occurs beyond full employment output.

(Lower case (u))- stands for employment
(Pie (๐žน))- stands for inflation


3 Ranges of Aggregate Supply


Horizontal or Keynesian Range- A lot of unemployed resources which creates a recession or depression. It includes only levels of only real GDP that are less than the full employment output.

Intermediate Goods- Resources are getting closer to the full employment level which creates pressure on wages and prices.

Classical or Vertical Range- This is where real GDP at a level with unemployment at the full employment level and where any increase in demand will result in only increase in prices. The economy is unable to produce any more goods and services for a sustainable period of time.











Unit 3- Topic 2: Aggregate Supply

Aggregate Supply- The level of Real GDP that firms will produce at each price-level.

Long-Run v. Short-Run

Long-Run 

  • Period of time where input prices are completely flexible and adjust to change in the price-level.
  • In the long-run, the level of Real GDP supplied is independent of the price-level
  • Vertical

Short-Run

  • Period of time where input prices are STICKY and do not adjust to changes in price-level.
  • In the short-run, the level of Real GDP supplied is directly related to the price-level.

Long-Run Aggregate Supply (LRAS)

  • Always located with full employment 
  • The Long-Run Aggregate Supply marks the level of full employment in the economy. 
  • Analogous to PPC

Short-Run Aggregate Supply (SRAS)

  • Because input prices are sticky in the short-run, the SRAS is upward sloping.


Changes in SRAS

  • Increase: SRAS →
  • Decrease: SRAS ←
  • The key to understanding shifts in SRAS is per unit cost of production.
  • Per Unit Production Cost Formula: (Total Input Cost/Total Output Cost)

Determinants of SRAS

  1. Input Prices
  2. Productivity
  3. Legal- Institutional Environment

1) Input Prices

Domestic Resource Prices

  • Wages (75% of all business costs)
  • Cost of captial
  • Raw materials (commodity prices)

Foreign Resources Prices

  • Strong $= lower foreign resource prices
  • Weak $= higher foreign resource prices

Market Power

  • Monopolies and cartel that control resources control the price of those resources
Increase in resource prices= SRAS ←
Decrease in resource prices= SRAS →

2) Productivity

Productivity= (Total Output/ Total Input)
  • Most productivity= lower unit production cost= SRAS →
  • Lower productivity= higher unit production cost= SRAS ←

3) Legal- Institutional Environment 

Taxes and Subsidies
  • Taxes ($ to gov't) on business increase per unit production cost = SRAS ←
  • Subsidies ($ from gov't) to business reduce per unit production cost= SRAS→
Government Regulation
  • Government Regulation creates a cost of compliance = SRAS ←
  • Deregulation (lift up rules and regulation, set your own price) - Reduces compliance costs= SRAS →

Unit 3- Topic 1: Aggregate Demand

Aggregate Demand (AD)- Shows the amount of Real GDP that the private, public, and foreign sector collectively desire to purchase at each possible price level.


  • AD is demand by consumer, business, government, and foreign countries.
  • Changes in price level causes a MOVE not a SHIFT
  • The relationship between the price level and the level of Real GDP is INVERSE (↑↓,↓↑)
  • AD= GDP= C+Ig+G+Xn

3 Reasons why AD is downwards sloping



  1. Wealth Effect- higher prices reduce purchasing power of $, decreases the quantity of expenditures, lower price levels increase purchasing power. (EX. if the balance in your bank was $50,000, but inflation erodes your purchasing power, you will most likely reduce your spending.) PRICE LEVEL GOES UP, GDP DEMAND GOES DOWN. (↑,↓)
  2. Interest-Rate Effect- As price level increases, lenders need to charge higher interest rate to get a REAL return on their loans. Higher interest rates discourage consumer spending and business investment. (EX. Increase in price leads to an increase in the interest rate from 5% to 25%. You are less likely to take out loan to improve your business.)
  3. Foreign Trade Effect- When U.S. price level rises, foreign buyers purchases fewer U.S. goods and American buy more foreign goods. Exports fall and import rises causing real GDP demanded to fall. (Xn Decreases). (EX. If prices triple in the US, Canada will no longer buy US goods causing quantity demanded of US products to fall.)

Shifts in Aggregate Demand

  1. A change in C, Ig, G, Xn
  2. A multiplier effect that produces a greater change than the original change in the 4 components.

Increase in AD= AD →
Decrease in AD= AD ←
Determinants of AD


  • Consumption (C)
  • Gross Private Investment (Ig)
  • Government Spending (G)
  • Net Exports (Xn)= Exports-Imports 


Consumption (C)
  • Consumer Wealth- boom in the stock market...
  • Consumer Exception- people fear a recession...
  • Household Indebtedness- more consumer debt...
  • Taxes- decreases in income taxes...

Gross Private Investment (Ig)
    • Real Interest Rate- price of borrowing $...
    • Future Business Exceptions- higher exceptions...
    • Productivity and Technology- new robots...
    • Business Taxes- higher corporate taxes means...
    Government Spending (G)
    • War
    • Nationalized Health Care
    • Decreases in defense spending
    • Increase in government spending (AD → )
    • Decrease in government spending (AD ←)
    Net Exports (Xn)= Exports-Imports 
    • Exchange Rate- if the US dollars depreciates relative to the euro
    • National Income Compared to Aboard- if a major importer has a recession. If the US had a recession.
    • "If the US gets a cold, Canada gets Pneumonia"

    Unit 2- Topic 4: Unemployment



    Unemployment-
    • Failure to use available resources particular labor to produce desired goods and services.

    Population-
    •  Number of people in a country

    Labor Force-

    • Number of people in a country that are classified as either, employed or unemployed.
    • Employed- people who are 16 year of age or older and they have a job. must work one hour every two week to be considered as employed.
    • Unemployed- people who are 16 years of age or older that don't have a job but actively searched for a job in the past two weeks.

    Not in the Labor Force-

    • Kids
    • Full Time Students/ College Student
    • Institutionalized (mental institution)
    •  People in Jail or Prison (state intimates do not get paid)
    • Disabled 
    • Retirees
    • Military Personals
    • Stay at home moms and dads 
    • Discouraged Workers
    Total Labor Force#of unemployed+#of employed
    Unemployment Rate= # of unemployed/ Total Labor Force (# of unemployed + employed)

    Types of Unemployment

    Frictional-
    • Temporarily unemployed on “in -between” jobs 
    • Qualified works with transferable skills 
    • EX. High school/ college graduate, people looking for a better job. 
    Seasonal-
    • Due to the time of the year 
    • EX. Lifeguards, construction workers, school bus drivers, mall Santa’s, Easter bunnies 
    Structural-
    • Changes in the structure of the labor force makes some skills obsolete
    • Workers don’t have transferable skills
    • Jobs will never come back
    • Creative destruction- jobs are created or destroyed 
    • EX. VCR repairmen, typewriter repairmen, works in NASA           
    Cyclical-

    • Demand for goods and services falls, demand for labor falls and workers are laid off. 
    • Results from economic downturns = recession
    • Known as the worst kind of unemployment.
    • If cyclical unemployment is present we do not have full employment. 

    Full Employment-
    • 4-5% unemployment (There is no Cyclical Unemployment)
    • NRU= frictional+structural unemployment
    NRU-
    • Natural Rate of Unemployment (Frictional + Structual Unemployment = NRU)
    Okun’s Law-
    • When unemployment increases by 1% above the natural rate of Unemployment then real GDP will fall by 2%. EX. natural rate: 5.5% real: 6.5%, 6.5-5.5=1 x 2= 2
    Rule of 70-
    • The number of years that is required for GDP to double.
    • EX. If the annual inflation rate is 2% how many years will it take for GDP to double? 70/2 = 35 years 

    Unit 2: Topic 3- Inflation



    Inflation: reduces the purchasing power of money
    • When inflation occurs, each dollar of income, will buy fewer goods than before.
    • Inflation Rate: 2-3%

    3 Causes of inflation

    1. Hyper- inflation:The government prints too much money. 
    2. Demand-Pull Inflation: (demand pulls up prices): too many dollars chasing too few goods. demand pulls prices up. 
    3. Cost-Push Inflation: higher production costs increases prices 
    Unanticipated Inflation- Unexpected change in price

    People hurt my inflation
    • lenders/ predators (borrow money at fixed rates)
    • people on a fixed income; receiving social security or retirement. (ex. senior citizens)
    • savers
    • creditors
    People helped by inflation
    • borrowers/ debtor: signed contract, conditions cannot change.
    • flexible income
    • a business where the price of a product increases faster than the price of resources.

    Nominal Interest Rate vs. Real Interest Rate

    Nominal Interest Rate: adjusted cost of borrowing or lending out money.
    Real Interest Rate: the cost of borrowing or lending money that is adjusted for inflation.
    Nominal - inflation = 

    Unit 2: Topic 2- Gross Domestic Product (GDP)

    Gross Domestic Product (GDP)- Total market value of all final goods and services produced within a countries border within a given year.
    Gross National Product (GNP)- A measure of what a citizens produce whether they produce these items within it's borders.

    What's the difference?

    GDP- total market value
    final goods and services
    within a year
    within a countries border

    GNP- (ex.) working in Dubai, an american citizen would not be on Dubai's GDP.


    What's not included in GDP?

    1. Used or "second-hand" goods- trying to avoid double or multiple accounting. (If you buy a a 2005 car in 2018 then only the value of 2005 is valid)
    2. Intermediate Goods- these are goods that require further processing before they are ready for final use. (a big mac- the bun, the cheese, the lettuce are all intermediate goods. Things put together to make a product.)
    3. Gifts (transfer payment)- public or private. (public- welfare social security, private- scholarship) transfer of money. No output produced. The recipients do not contribute to current production. NO PRODUCTION
    4. Unreported Business Activity ("tips")- If you get a tip and don't clock it then no proof to effect the GDP.
    5. Illegal Activities- Drugs, prostitution, human trafficking. 
    6. Stocks and Bonds- not include in GDP, purely transaction. no output being produced.
    7. Non Market Activity- volunteer and family work. (babysitting not an official job)

    FORMULA FOR GDP

    (Expenditures Approach) GDP= C+Ig+G+Xn
    C- Personal Consumption Expenditures- (67% of economy) purchase of finished goods and services. does not include houses. (ex. going to the mall and buying a purse)
    I- Gross Private Domestic Investment- new factory equipment, construction of housing, unsold inventory of products built in a year, factory equipment maintenance.
    G- Government Spending- Government purchases of goods and services.
    Xn- Net Export- (Export- Imports) Export- make money, Imports give money


    Formulas for trade and budget

    Trade: (exports-imports)

    Surplus: positive
    Deficit: negative

    Budget: government purchases of goods and services + government transferred payments - government tax and fee collections
    Budget Deficit = total amount of money that the government borrows in a given year (because total government spending exceeds tax and fee revenue.)

    Deficit: positive
    Surplus: negative

    National Income

    Option 1: compensation of employees+ rent + prop income + interest income + corp profit
    Option 2: expenditure approach to GDP - indirect business taxes - depreciation (consumption of fixed capitals) - net foreign factor payment

    Disposable Personal Income (DPI): national income - household taxes + government transferred payments

    Net Domestic Product: GDP- Depreciation
    Net National Product: GDP- Depreciation
    Gross Private Domestic Investment: Net Private Domestic Investment + Depreciation

    Real vs. Nominal GDP

    Nominal GDP = value of output produced in current prices. (PxQ)

    Real GDP = Value of output produced in constant base year prices (first original year that is being indicated) that is adjusted for inflation. (Base year PxQ)

    Nominal GDP can increase from year to year.
    Real GDP can increase from year to year only if output increases. (output is quantity)
    In the base year the current price is going to be equal to the base year price. (Real GDP = Normal GDP)

    In years after the base year, Nominal GDP exceeds real GDP.
    In years before the base year, Real GDP exceeds Nominal GDP.

    Real GDP: 2-3%

    GDP Deflator: nominal/ real x 100
    Price index that is used to adjust from Nominal to Real GDP. 
    in the base year, the GDP deflator will = 100.
    after the base year = greater than 100.
    before the base year = less than 100.

    Inflation Rate((new-old)/old x 100)

    CPI: (price of market basket in the particular year/ price of the same market basket in the base year) x 100

    Unit 2: Topic 1: Circular Flow

    Circular Flow

    Household- It is a person or a group of people who share an income.

    • sell resources, buy products.

    Firms- An organization that produces goods and services for sale.

    • buy resources, sell products

    Factor (Resource) Market- This is where factors of production are sold. Bought by firms and sold by households. Factor of production: land. labor, entrepreneurship, capital (human, physical)



  • Firms buy.
  • Household sell.
  • Product Market- The market where goods and services are bought and sold.

    • Firms sell.
    • Household buy

    Factor payments-

    • LAND- rent
    • LABOR- wages

    Unit 1: Topic 4- Business Cycles

    Unit 1: Topic 4- Business Cycles

    Business Cycles- Fluctuation in economic activity that an economy experiences over a period of time

    Expansion- periods of economic upturn when output and employment are rising.
    Peak- (the highest point) this is the period where business has reached a temporary maximum, near/at full employment.
    Contraction-(recession) period of decline in total output, income, and employment
    Trough - Lowest point, goes from recession to depression

    Unit 1: Topic 3- Demand and Supply

    Unit 1 Topic 3

    Demand and Supply

    Demand- The quantities that people are willing and able to buy at various prices.
    P↑Q↓, P↓Q↑
    Demand schedule- Always down flowing.
    As price decreases the quantity increases.]
    Supply- The quantities that supplies/ producers (Sellers) are willing and able to produce/sell at various prices.
    P↑Q, P↓Q
    Supply Schedule- Always upwards flowing.
    The Law of Demand- Inverse relationship between price and quantity demanded.
    Delta (๐Ÿ”บ)- Change in price







    Determinants of Demand- What causes the change in Price

    1. ๐Ÿ”บ in buyers taste -advertising
    2. ๐Ÿ”บ in number of buyers -population
    3. ๐Ÿ”บ in income- Normal Goods- goods that buyers buy more of when income rises. Inferior Goods- goods that buyers buy less of when income rises.
    4. ๐Ÿ”บ in price of related goods- Substitute Goods- goods that serve roughly the same purchase to buyers. Complimentary Goods- goods that are often consumed together. (EX. Hamburgers and Fries)
    5. ๐Ÿ”บ in expectation (future)
    The Law of Supply- There is a direct relationship between price and quantity supplied.

    Determinants of Supply

    1. ๐Ÿ”บ in number of sellers (supplies/producers)
    2. ๐Ÿ”บ in the cost of production (salary, wages)
    3. ๐Ÿ”บ in technology 
    4. ๐Ÿ”บ in weather 
    5. ๐Ÿ”บ in taxes/ subsides- government gives money
    6. ๐Ÿ”บ in expectation (future)
    Total Revenue- Price multiplied quantity.
    Elasticity of Demand- Measure of how consumers react to a change in price.
    Inelastic Demand- The demand of good will not change or will change very little regardless of price. I<1
    Elastic Demand- Demand will change greatly given a small change in price. E>1
    Unitary Elastic Demand- E=1

    Price Elastic of Demand

    Step one: Quantity- new-old
                                       old
    Step two: Price-       new-old
                                        old
    Step three: Price Elasticity of Demand (PED)% ๐Ÿ”บ of quantity
                                                                                % ๐Ÿ”บ of price
    Fixed Cost- it is a cost that does not change, no matter how much of a good is produced. (EX. salary, insurance, mortgage)
    Variable Cost- a cost that rises and falls depending upon how much is being produced. (EX. electricity) 
    Marginal Cost- the cost of producing one more unit of a good.

    Price Ceiling- a legal maximum price meant to help buyers. (EX. Rent control)

    4 Consequences of Price Ceiling

    1. Lower prices for some consumers.
    2. Shortage
    3. Long line for buyers
    4. Illegal sales above the equilibrium price.

    Price Floor- a legal minimum price meant to help the sellers, keeps prices from falling. (EX. Minimum wage)

    4 Consequences of Price Floor

    1. Higher product prices.
    2. Surplus
    3. Higher Taxes
    4. Waste (never been used products)

    Unit 1: Topic 2- Production Possibilities Graphs

    Unit 1 Notes

    Production Possibilities Graphs

    Production Possibilities Graphs- Alternative ways to use resources. Show the most that society can produce if it uses very available resource to the best of its ability.
    • PPGProduction Possibilities Graphs
    • PPC- Curve
    • PPFFrontier
    Six Key Assumption
    1. Full Employment- 80-90% factory capacity. 4-5% unemployment (IDEAL) ๐Ÿ’ช Reasons why full employment isn't going to happen;๐Ÿ˜ž never will happen, people are lazy, have no skills, won't work.)
    2. Productive Efficienc
    3. Fixed Resources- Land, Labor, Capital, Entrepreneurship
    4. Fixed State of Technology
    5. No International Trade
    6. Two Goods are Produced
                                                              Movements of the PPG
    1. Inside of the curve- Any point on the inside
    2. Along the curve- Moving along the curve. (Directional flow)
    3. Shifts of the curve- Can be both on the inside and the outside.
    Opportunity Cost- The next best alternative that you must give up in order to get something. (EX. Should i study for a test or should i go to a party?) Not your first choice. Form of trade-off.
     Law of Increasing Opportunity Cost- As you produce more of one good, the opportunity cost(the forgone production of another good) will increase. (HAVE TO BE PRODUCING ONE MORE THAN OTHER, CANNOT PRODUCE EQUALLY)
    Concave vs. Constant PPG- 
                          Concave- Increasing at every level.
                          Constant- Straight line
     Productive Efficiency vs. Allocate Efficiency
    Productive Efficiency- Products are being produced in the least costly way. Any point on the PPG.
    Allocative Efficiency- The products being produced are the ones are the most desired by society.
