Unit One: Chapter 19- Business Cycle

Business Cycle

Notes from (1/21/16)

Expansion- Where real GDP is increasing, which causes spending to increase, and unemployment decreases.
-A.K.A. Recovery Phase

Peak- The highest point of real GDP
-Lowest unemployment and greatest spending

Recession/Contraction- Where real GDP decreases for 6 months
-Increase in unemployment and a reduction in spending

Trough- Lowest point of real GDP
-Highest unemployment and least amount of spending
-Means the end of a recession

FACTS
  1. Average cycle is 5-7 years
  2. One cycle is from trough to trough
  3. Recessions last about 14 months
  4. Peaks and troughs are meaningless because we never know we're in one until it's over.
  5. If a recession loses more than 10% of real GDP, then it is called a depression.

Unit One: Chapters 3 and 4- Price Ceiling and Price Floor

Price Ceiling and Price Floor

Notes from (1/20/16)


Equilibrium- Where supply and demand lines intersect on a graph
-All resources are being used efficiently and everything is balanced




Price Ceiling- A limit on how high the price of a product can be
-Ceiling below the equilibrium causes a shortage
-To be effective, must be set above the equilibrium



Price Floor- The lowest legal price a product can be sold
-Floor above the equilibrium will cause a surplus 
-Used by governments to prevent prices from being too low
-Ex.: Minimum Wage


Excess Demand- Quantity demanded is greater than Quantity supplied.
-Results in shortages

Excess Supply- Quantity demanded is less than Quantity supplied.
-Results in a surplus

Elasticity of Demand Help!

NEED SOME HELP?

Okay so I found a like to a well-known website with a few already worked out problems dealing with Elasticity of Demand! 

Click here for the link---------------> Elasticity of Demand Problems

P.S.- It's Sparknotes ;)

Supply and Demand Help!

NEED SOME HELP?


Hey y'all! I found a source that will help with some of the vocabulary in Supply and Demand.

Click here for the link----------> Supply and Demand Vocabulary

P.S.- It's a Quizlet ;)

Unit One: Chapters 3 and 4- Supply Formulas

SUPPLY FORMULAS

Notes from (1/14/16)

Here is where calculators come into Macroeconomics for the first time! There are 7 terms abbreviated in a chart like shown below! 


  • Total Fixed Cost = TFC
  • Total Variable Cost = TVC
  • Total Cost = TC
  • Average Fixed Cost = AFC
  • Average Variable Cost = AVC
  • Average Total Cost = ATC
  • Marginal Cost = MC
There are formulas to calculate these variables! As we do these calculations more, we will get faster and faster! (Hopefully...)

- TFC + TVC = TC
- AFC + AVC = ATC
- TFC / Q = AFC
- TVC / Q = AVC
- TC / Q = ATC
- TFC = (AFC) (Q)
- TVC = (AVC) (Q)
- MC = New TC - Old TC

Unit One: Chapters 3 and 4- Elasticity of Demand

ELASTICITY OF DEMAND

Notes from (1/13/16-1/14/16)

Elasticity of Demand- A measure of how consumers react to a in price

TYPES OF DEMAND

Elastic Demand- Demand that is very sensitive to a in price
- E > 1 
-Product is not a necessity and there are available substitutes  
  • Examples: Soda, Steak, Candy, Fur Coats

Inelastic Demand- Demand that is not very sensitive to a in price 
- E < 1 
-Product is a necessity with few to no substitutes
-People will buy no matter what
  • Examples: Gas, Salt, Medication, Milk
Unit/ Unitary Elastic Demand
- E = 1

Price Elasticity of Demand (PED) 

3 IMPORTANT STEPS

1.) Quantity

New Quantity - Old Quantity
--------------------------------------------
Old Quantity

2.) Price

New Price - Old Price
------------------------------------------
Old Price

3.) PED

in QD
---------------------------
in Price


P.S. At the end of the 3rd step, you take the ABSOLUTE VALUE of the number so you always end up with a positive number! 

Total Revenue- The total amount of money a firm receives from selling goods and services

TR = PQ

Fixed Cost-  A cost that does not change no matter how much is produced 
  • Examples- Rent, Mortgage, Insurance, Salaries
Variable- A cost that rises or falls depending upon how much is produced
  • Example- Electricity
Marginal Cost- The cost of producing one more unit of a good
  • Prior TR - New TR 

SUPPLY Cheat Sheet!

SUPPLY CURVE SHIFTS!

Alright everyone! There's a cheat sheet to understanding how and why Supply Curve Shifts happen on graphs!

The top picture is Figure 1 and the bottom picture is Figure 2
Figure 1                                                      Figure 2
- Cost of Production ↑                              -Cost of Production  
- Technology ↓                                         -Technology 
Taxes ↑                                                 Taxes  
- Subsidies ↓                                            Subsidies 
- Number of Sellers ↓                               - Number of Sellers  
- Weather ↓                                              Weather ↑

Unit One: Chapters 3 and 4- SUPPLY and Demand

SUPPLY

Notes from (1/12/16)


Supply- The quantities that produces or sellers are willing and able to produce at various prices.

The Law of Supply- There is a direct relationship between price and quantity.

-As Price INCREASES, Quantity INCREASES. As Price DECREASES, Quantity DECREASES.

QUESTION?- What causes a "change in quantity supplied"?

ANSWER- in price! 

QUESTION?- What causes a "change in supply?"

ANSWER- There are 6 reasons!

1.) in Weather (Drought, Natural Disaster, etc.)

2.) in Number of Sellers

3.) in the Costs of Production

4.) in Technology

5.) in Expectations

6.) in Taxes of Subsidies*

*Subsidies- Money provided by the government


SHOULD KNOW'S


-Supply Curve Shift LEFT means supply DECREASES.
-Supply Curve Shift RIGHT means supply INCREASES.


PANEL (a) SHOWS: An INCREASE in Technology, Subsidies, Weather, and Number of Sellers and a DECREASE in Cost of Production and Taxes.

PANEL (b) SHOWS: An INCREASE in Cost of Productions and Taxes and a DECREASE in Technology, Subsidies, Weather, and Number of Sellers.

Unit One: Chapters 3 and 4- Supply and DEMAND

DEMAND

Notes from (1/11/16)


Demand- The quantities that people are willing and able to buy at various prices.

The Law of Demand- States that there is an inverse relationship between price and quantity demand.

-Price INCREASES, Quantity DECREASES. As Price DECREASES, Quantity INCREASES.

Translation- When something happens to one thing, the total opposite happens to the other! As shown in the graph above! 

QUESTION?- What causes a "change in quantity demanded"? (QD)

ANSWER- in price

P.S.- We use the Delta sign to represent change now! (Looks like a triangle...It's a triangle)

QUESTION?- What causes a "change in demand"? (D)

ANSWER- There are 5 reasons!:

1.) in Buyer's Taste (Advertisement)

2.) in the Number of Buyers (Population)

3.) in the Price of Related Goods:
     -Complimentary Goods
     -Substitute Goods

4.) in Income
     -Normal Goods: As people's income rises, demand for goods and services rise
     -Inferior Goods: An increase income causes a fall in demand. 

5.) in Expectations (Always looking towards the future)

Unit One: Chapters 1 and 2- Productions Possibilities Graphs

PRODUCTIONS POSSIBILITIES GRAPHS

Notes from (1/6/16-1/7/16)

VOCABULARY

Trade Offs- Alternative that we give up when we choose one course of action over another

Opportunity Cost- Form of trade off
-   Next best alternative
-   "Settling"

Efficiency- Using resources in such a way as to maximize the production of goods and services

Underutilization- Using fewer resources than the economy is capable of using

Allocative Efficiency- Products being produced are the ones desired by society

Productive Efficiency- Products being produced in the least costly way

NEED TO KNOWS

Production Possibilites Curve (PPC)
Production Possibilites Frontier (PPF)
Production Possibilities Graph (PPG)- Shows alternative ways to use an economy's resources

P.S.- PPC and PPF are the same thing!

FOUR ASSUMPTIONS OF THE PPG

1.) There are 2 goods: Cannot produce more than 2 goods at a time
2.) Fixed Resources: Quantities of factors of production stay the same
3.) Fixed Technology: Information and knowledge about resources stays the same
4.) Full Employment of Resources


Point A- Inside the Curve
-  Attainable, but Inefficient
-  Underutilization

Points B, C, D- On the Curve
-  Attainable, and Efficient

Point X- Outside the Curve
-  Unattainable


TYPES OF MOVEMENT IN PPC

1.) Inside the PPC- Means resources are unemployed or underemployed, Productive Efficiency 
2.) Along the PPC- Can shift along the curve, but cannot go IN or OUT
3.) Shifts of the PPC- When resources and technology change

CAUSES THE PPC/PPF TO SHIFT

1.) Technological Change
2.) Change in Resources
3.) Change in the Labor Force
4.) Economic Growth
5.) Natural Disasters/ War/ Famine
6.) More Education or Training (Human Capitol)

Cute Explanation of the Factors of Production

THERE'S A VIDEO!

So while looking around for something to explain factors of production in a way that actually gives a nice explanation, I found what I think is the cutest little video made by two girls who put the concept into perspective...

Clicking here will take you right to it! --------> Factors of Productions Video

P.S. In class, we got the suggestion that to remind yourself of the four factors use the acronym C.E.L.L. 

C- Capital
E- Entrepreneurship
L- Land
L- Labor

If you're into acronyms like that!
