Unit 3: Fiscal Policy

3/06/17
Fiscal Policy 
  • Fiscal Policy
- Actions by congress to stabilize the economy.
- 2 Tools to Fiscal Policy 
  1. Taxes- Government can increase or decrease taxes
  2. - Spending- Government can increase or decrease spending 
- Fiscal policy is used to promote our nations economic goals: full employment, price stability, and economic growth .
  • Deficit, Surpluses, and Debt
*Balanced Budget
- Revenues ( bring in)= Expenditures (spend)
*Budget Deficit
- Revenues < expenditures
*Budget Surplus
- Revenues> expenditures 
*Government Debt
- Sum of all deficits- sum of all surpluses 

- The government can borrow money when it runs a budget deficit, They can borrow from...
- Individuals
-Corporations
-Financial institutions
-Foreign entities 
  •  Options of fiscal Policy 
  1. Discretionary fiscal policy (action by congress)
  2. Expansionary fiscal policy (think deficit)
  3. Contractionary fiscal policy ( think surplus)
  4. Non-discretionary fiscal policy (no action)
  • 3 Types of Taxes 
- Progressive Tax- Takes a larger % of income from high income groups
- Proportional Tax- Takes the % of income from all income groups 
- Regressive Taxes- Takes a larger % from low income groups ( takes more from poor people)
  • Contractionary Fiscal Policy
- laws that reduce inflammation, decrease GDP and close the inflationary gap 
-  they can either decrease government spending or increase taxes or a combination of the two 
  •  Expansionary fiscal policy 
- laws that reduce unemployment and increase GDP and close a recessionary gap 
- they can either increased government spending or decrease taxes are consumers or a combination of the two 
  •  Automatic or built in stabilizers 
- anything that increases the government budget deficits during a recession and increase its budget surplus during installation without requiring explicit action by policymakers 
  •  Transfer payments 
- welfare checks 
- food stamps 
- unemployment checks 
- corporate dividens
-  social Security 
- veterans benefits 

Unit 3: Consumption and Savings

2/23/27
Consumption and Savings 
  • Disposable Income 
- Income after taxes or net income
-DI= Gross income-Taxes
-2 Choices with disposable income households 
  1. Consume (spend money on goods and services)
  2. Save ( not spend money goods and services)
  • Consumption 
- Household spending
- the ability to consume is constrained 
- The mount of disposable income  
- The propensity to consume
-Do households save if DI=0? No
-APS= S/DI= % DI that is not spent
  • Average Perpencitry to Consume/ Save (APS) (APC)
- APC+APS=1
-1-APC=APS                *https://www.youtube.com/watch?v=mjU1w9jwYwY ( diposible income)
-1-APS=APS
-APC>: Disaving
-APS: Disaving
  • Marginal Perpencity to Consume/ Save (MPC)(MPS)
-MPC
- Change in consumption/ change in disposable income
-% of every extra dollar earned 
-MPS
- Change in savings/ change in disposable income
- % of every extra dollar earned is saved 
-MPC-MPS=1
-1-MPC=MPS
-1-MPS=MPC
  • Determinants of C and S
- Wealth
- Household Debt
- Expectations
- Taxes
2/24/17
  • Spending Multiplier Effect
- An initial change in spending (C, Ig, G, Xn) causes a larger change in aggregate spending or aggregate demand.
-Multiplier= Change in AD/ Change in spending 
- Expenditures- Income and 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 MPS
- Multiplier=1/ MPC OR 1/1-MPS
- Multipliers are positive where there is an increase in spending and negative when there is a decrease.
  • Calculating Tax Multiplier 
- When the government taxes, the multiplier works in reverse  because now money is leaving the circular flow.
- -MPC/1-MPC or -MPC/MPS
- If there is a ta cut , then multiplier is positive because there is now more money in the circular flow.

2/27/17

Reasons why prices tend to be sticky or inflexible in a downward direction...

  1. Fear of price wars 
  2. wage contracts 
  3. minimum wage 
  4. Menu Costs
  5. Moral effort and productivity 




  • 3 Ranges of AD
- Range 1: Output is low, relative to the economy and full employment output; unemployment increases and GDPr decreases.
- Range 2: Output expands as spending increases.
- Range 3: The AS is vertical in the log-run, because the only effects would increase in AD we are already at full employment or an increase in demand by increasing output.

2/28/17

  • Classical School 
- The trickle down theory: Help the rich first and then everyone else
- In the LR the economy will balance at full employment output
- The invisible hand

  • Keynesian School 

- AD is key not AS
- In the LR we are dead
- Leaks cause recessions
- Saving causes recesssions

Unit 3: Aggregate Supply

2/21/17

  • Aggregate Supply- Level of real GDP that firms will produce at each price level
  • 2 types of aggregate supply
  1. Long run- Period of time where input prices are completely flexible and adjust to change in the price level 
 - Vertical line in the middle of the graph= Long run
     2. Short Run- Period of time where input prices are sticky and do not adjust to changes in the price level.
- In the short run the level of GDPr supplied directly to the price level
Long Run Aggregate supply
-The LRAS  marks the level of full employment in the economy                                                       
-The LRAS  marks the level of full employment in the economy                                                    

Short Run Aggregate supply              
 -Because the input are sticky the SRAS is are upward slopping
-an increase in SRAS is as a shift to the right
- a decrease in SRAS is seen as a shift to the left.
- The key to understanding shifts in SRAS is id per unit cost cost of production 
- Per unit cost =(total input cost/ total output
Determinants of SRAS 
  • Input prices
- domestic resource prices
- wages (75% of all business costs)
-cost of capital 
-raw materials (commodity prices)
* Foreign resource prices 
-Strong $= lower foreign resource
-weak $= higher foreign resource 
*Market Power 
-Monopolies and cartels that control resources control the price of those resources
- increase in resource prices= decrease in SRAS 
- decrease in resource prices = increase in SRAS
  • Productivity
- Productivity= total output/ total inputs
- More productivity = lower unit production 
- lower productivity = higher unit production 
  • Legal Institutional Environment

- Taxes and subsidies 
- taxes on businesses increase per unit production
-subsidies to businesses reduce per unit costs 
-Government regulation 
- Government regulation creates a cost of compliance 
-deregulation reduces compliance cost

Unit 3: What is Invetment

2/21/17
Investment
  • Investment- Money spent or expenditures on...
-New plants (factories)
-capital equipment (machinery)
-technology (hardware and software)
-new homes
-inventory
  •  Expected rates of return
*How do businesses make investment decisions?
-cost/benefits analysis
*How do businesses determine the benefits?
-expected rates of return
*How do businesses determine the amount of investments they should undertake?
-Compare expected rate of return too interest of cost
-If the expected rate of return is greater than interest cost = investment
- if the expected rate of return is less than the interest cost = no investment
-r%( real investment)= 1%(nominal rate)-π(inflation)
Investment Demand Curve (ID)
  • The investment demand curve is downwards slopping because when the interest rates are high fewer investments are profitable; when interior rates are low more investments are profitable.
  • Shifts in AD ...
- Cost of production
- Technological change 
- Stock capital 
-Business taxes

Unit 3: Aggregate Demand

2/16/17
Aggregate Demand
  • AD is the demand by consumers businesses, government and foreign countries.
  • Changes in the price level cause a move along the curve not a shift of the curve.
  • Aggregate Demand- Shows the amount of real GDP that the private, public , and foreign sector collectively desire to purchase at each possible price level.
  • The relationship between price level and the level of real GDP is inverse.
  • 3 Reasons why AD is Downward Slopping
  1. Wealth Effect
-Higher prices reduce the purchasing power of money
-This decreases the quantity of expenditures
-Lower price levels increase purchasing power and increase expenditures
    
 2. Interest Rate Effect
- As price levels increase, lenders need to charge a higher interest rate to get a real return on their loans 
- Higher interest rates discourage consumer spending and business investments 
 3. Foreign Trade Effect
- When US price level rises, foreign buyers purchase fewer US goods and Americans buy more foreign goods 
- Exports fail and imports rise causing real GDP demanded to fall
  • Shifts in Aggregate Demand
-There are 2 parts to shift in AD
- a change in  C.Ig,G, and/or Xn
-a multiplier effect that produces a greater change than original change in 4 components 
- Increase in AD= Right shift   Decrease in AD= Left shift in AD
2/17/17
  • Determinants of AD
- Consumption (C)
- Gross private investment (Ig)
-Government (G)
- Net Exports (Xn)

  • Consumption- Change in consumer spending 
- Consumer wealth: boom in stock market
- Consumer expectation: people fear a recession
- Household indebtedness: more consumer debt
- Taxes: a decrease in income tax
  • Gross private investments- change in investment spending
- Real interest rates (price of borrowing money), if interest rates increase if interest rates decrease
- Future business expectations: high expectations
- Producing: productivity technology- new robots
- Business taxes: higher corporate taxes
- Government- Change in government spending
- War, national health care, decrease in defense spending.

  • Net exports- change in net exports(x-m)
-exchange rates: if the US dollars depreciate it is relative to zero
- National income compared too abroad, if a major importer has a recession , if US has a recession
-" If the US gets cold Canada gets pneumonia."
AD= GDP=C+L+G+Xn

  • Government Spending 
- more government spending= AD increasing
-less government spending = AD decreasing

Unit 2: Unemployment

3/9/17
Unemployment 
  • Unemployment-  percentage of people who do not have a job in the labor force 
  •  Unemployment rate- % of people who want a job but are not working 
  • Unemployment rate =( # of unemployed/ # in labor force) x 100
  • 4 types of unemployment...
  1.  Frictional unemployment-  temporarily unemployed or between jobs 
-  individuals are qualified workers with transferable skills but they aren't working
    2.   Seasonal  unemployment -  due to time of the year and the nature of the job 
    3.   Structural unemployment -  changes in structure of the labor force make some skills obsolete 
- workers do not have transferable skills and these jobs never come back 
-  permanent loss of these jobs is called "creative construction"
    4.  Cyclical unemployment-  downturns in the business cycle 
-  As demand for goods and services falls demand for labor falls and workers are fired
  • Standard unemployment rate - 4 to 5%
  • Natural rate employment 
-  two of the three types of unemployment are unfavorable
-  frictional unemployment 
- structural unemployment 
-  together they make up the natural rate of unemployment,
 frictional + Structural = NRU
- Full employment =  no slip a cool employment full employment 
-Okund Law-  when unemployment rises 1% above the NRU gap falls about 2% 

Unit 2: Inflation

Continuation of 2/3/17...


  • GDP deflator- Price index used to adjust from nominal GDP to real GDP.
-(Nominal GDP/Real GDP) x 100
- In the base year GDP deflator will always equal to 100
-Years after the base year the GDP will be greater than 100
-Years before the base year the GDP deflator is less than 100
  • Consumer price Index (CPI)
- Measures inflation by tracking changes in the price of  a market basket goods ( cars, trucks, etc).
-(Price of market basket in current year/ Price of market basket in base year) x 100

2/6/17

Inflation 

  • Inflation- Increase or rise in price, it reduces the "purchasing power" ( the amount of goods and services your money can buy) of money
  • 3 causes of inflation
  1. Printing too much money
  2. Demand- pull inflation by an excess of demand over output that pulls public prices upward 
  3. Cost push inflation- cause by a rise in per-unit production cost due to an increase in resource cost.
  • Ideal inflation rate= 2 to 3%
- Inflation: (current year price index- base year price index)/base year price index x(100)

Rule of 70-used to calculate the number of years it will take for the price level to double at any given rate.
  • Deflation- General decline in the price level.
  • Disinflation- Occurs when the inflation rate itself declines
  • Nominal interest rate- unadjusted cost of borrowing or lending money.
  • Real interest rate- cost of borrowing or lending money adjusted for inflation 
- real interest rate = Nominal interest rate-expected inflation 

Unanticipated Inflation 


  • Hurt by inflation ....
- lender – people who lend the money at fixed interest rates
- people with fixed incomes
-savers

  • Helped by inflation....
- borrowers - people who borrow money
- A business where the price of product increases faster than the price of resources

  • COLA (cost  of a living adjustment)-  some works have salaries that mirror inflation they negotiate wages that ride with inflation 
  • Here is a video elaborating on inflation
