AP MACROECONOMICS UNIT 4 VIDEOS


AP Macroeconomics Unit 4 - Part 1
·           Types of money:
1.commodity money- A good that has other purposes that also functions as money. Ex. Cows as money (MOST PREMATIVE)
2. Representative money- whatever you use as currency, represents a specific quantity of a precious medal. (gold Standard) drawback, value of the medal changes, effects value of currency.
3.Fiat money- money that is not backed by precious medal, legal tender, money must be accepted by transactions, value backed by the government.
·           Functions of money:
1.Medium of exchange- through money that exchanges happen.
2.Store of value- expect money to be stable. Putting money aside.
3.Unit of account-priceàworth (quality) ex. Named Brands

AP Macroeconomics Unit 4 - Part 3
·           price- interest rate (X axis)
·           Quantity- Y Axis
·           Demand slopes down (DM-demand for money)
·           Supply of money is vertical (Fixed unless FED moves it)- doesn’t vary on interest rate
·           FED government tax credit for 1st home buyer- increase demand for money
-When you increase demand you put upward pressure on interest rate
·           if FED wants to bring interest rate down, shift the supply of money to the right.
·           FED want to stabilized interest rate, if not then you cannot predict the level of investment and the level intransitive consumer spending, thus not able to manipulate aggregate demand to give you the right kind of economic change at the time.

AP Macroeconomics Unit 4 - Part 4
·           The FED: Tools of Money Policy-
Expansionary (Easy Money) increase
Contractionary (Tight Money) decrease
Reserve Requirement
Lower it
Raise it
Discount rate
Lower it- Doesn’t mean banks will borrow money (an Incentive)
Raise it
(Most Used) Buy/Sell gov’t bonds/ securities
FED buys bonds
(buy bonds= Big bucks)
FED sells Bonds
(FOMC does this)

·           Discount rate- the rate at which banks can borrow money from the FED.
Why? Short term- bank needs to meet its liquidity need.
·           Function of the FED- Lender as a last resort.
·           Federal Funds Rate- rate a which banks borrow money from each other.



AP Macroeconomics Unit 4- part 7

  • When the interest rate is low people demand more money and when the interest rate is high people get discouraged from borrowing money. 
  • Decrease in supply it reduces the national supply of loanable funds it decreases amount available in savings.
  • The money people save becomes more money for the banks to use as loans.
  • Increase in demand for loanable funds increases the interest rate.
AP Macroeconomics unit 4- part 8

  • In the money creation process banks create money by making loans.
  • More money is made due to multiplier deposit expansion and adding loans would give the same amount of money if we don't use excess reserves.
  • If a certain amount of money is deposited into a bank than the bank can loan less money until there isn't any more money left from that original deposit. 
  • By adding the all the loans given you get your potential total increase
AP Macroeconomics unit 4- part 9
  • In deficit spending government borrows money from americans. 
  • In a MKT graph demand for money increases in interest rates.
  • When the demand for money increases national supply in loanable funds is reduced.
  • The Fisher effect is the rule of interest rate and inflation rate being equal to each other

Automatic or built-in-stabalizers

February 29, 2016

Automatic or built-in-stabilzers

  • anything that increases the governments budget deficit during a recession and increases it's budget surplus during inflation.
  • DOES NOT REQUIRE GOVERNMENT ACTION
  • Unemployment compensation, Medicaid, Medicare, Wellfare, VA Benefit, Social Security



  • progressive tax system 

- Average tax rate (tax revenue/ GDP) rises with GDP
GDP rises = tax rises

  • Proportional tax system

-average tax rate remains constants GDP Changes

  • Regressive tax system 

-average tax rate falls with GDP


Discretionary v. Automatic fiscal policies

February 29, 2016

Discretionary v. Automatic fiscal policies

  • Discretionary- increasing or decreasing government spending taxes in order to return economy to full employment involves policy makers to solve problems
  • Automatic- unemployment compensation and marginal tax rates are examples of automatic policies that help mitigate the effect of excision and inflation automatic fiscal policy takes place without policy makers






Fiscal Policy

February 29, 2016

Fiscal policy

  • Expansionary and contractionary policy deficits and surpluses built-in-stabality
What it does:

  • changes in the expenditures or tax revenues of the federal government
-2 tools of fiscal policy

  1. Taxes- government can increase or decrease taxes
  2. spending- government can increase or decrease spending
Deficits, surpluses, and dept

  • Balanced budget
-revenues = expenditures

  • Budget deficit
-revenues < expenditures

  • Budget surplus
-revenues > expenditures

  • Government debt
-sum of all deficits- sum of all surpluses
  • government must borrow money when it runs a budget deficit
  • government borrows from
-individuals
-corporations
-financial institutions
-foreign entities or foreign
Fiscal policies two options
  • Discretionary fiscal policy (action)
  • Expansionary fiscal policy: think deficit
  • Contractionary fiscal policy: think surplus
  • Non- Discretionary fiscal policy ( no action)


Spending multiplier effect

February 25, 2016

Spending multiplier effect

  • An initial change in spending (C, Ig, G, Xn) causes a larger change in aggregate spending or Aggregate demand (AD)
-multiplier = change in AD/ change in spending
-multiplier = change in AD/ change in C, I, G or X

Calculations for spending multiplier

  • get calculated from MPC or the MPS
  • multiplier= 1/r-MPC or 1/MPS
  • multipliers are (+) when there is an increase in spending and (-) when there is a decrease
Calculating tax multiplier 

  • When the government taxes, the multiplier works in reverse
  • Money is leaving the circular flow
  • tax multiplier is negative
  • =-MPC/1-MPC or -MPC/MPS
  • Tax-cut then the multiplier is +, because now there is more in the circular flow

Consumption and Savings

February 25, 2016
Disposable income (DI)

  • income after taxes or net income
  • DI = gross income-taxes
(spender save)

2 choices 

  • with disposable income, households can either
-consume (spend money on goods and devices)
-save ( not spend money on goods and services)


Consumption

  • Household spending
  • ability to consume is constrained by
-The amount of disposable income
-propensity to save


  • Do households consume if DI= 0
-automatics consumptions

Savings

  • household NOT spending
  • ability to save is constrained by
-the amount of disposable income
-propensity to consume

  • Do households save if DI= 0 no.
APS & APC

  • APC+APS=1
  • 1-APC=APS
  • 1-APS=APC
  • APC >1 : dissaving
  • -APS : dissaving
(MPC) Marginal propensity to consume

  • fraction of any change in disposable income that is consumed
  • mpc= change in consumption/ change in disposable income
Marginal propensities

  • MPC+ MPS= 1
  • MPC = 1-MPS
  • MPS= 1-MPC
  • EITHER SPEND OR SAVE



Classical and Keynesian Schools

February 24, 2016

Classical school

  • competition is good
  • believe in the indivisible hand
  • economy will balance at full employment
  • economy is always to or at full employment
  • trickle down effect


Keynesian school

  • competition is flawed
  • AD is the key NOT AS
  • leaks and savings cause recessions
  • ratchet effects and sticky, wages bucks say's law
  • in the long-run we are dead
