Q

We at happens when the Supply curve shifts right?

A

Positive Shift

Q

We at happens when the Supply curve shifts Left ?

A

• Supply decreases at each price point
• Lower Equilibrium GDP
• Cost of producing item increases
- Ex: price of gold increases 
- less sold watches are made
• Wars or Crisis

Q

What are some examples of what would cause a POSITIVE shift?

A

• Price of Substitute goes up
- Price of Beef goes up then MORE demand for chicken

• Future price expected to increase
- War in MiddleEast Breaks out, people start lining up at Gas Stations

Q

What happens when there is a Negative Demand curve Shift?

A

• Demand decreases at Each price point
• Price of Compliment goods go up

• Boycott

  • Company commits a social blunder
  • Consumers boycott

• Consumer income rises

  • Demand for inferior goods drops as people have more money to spend
  • once people get better jobs they start Eating out at nicer places

• Consumer tastes change

• Contraction - less spending decreases equilibrium GDP

Q

Statement: increase in DEMAND ends a up being Larger than the amount of income Spent in the Economy due to the Multiplier effect.

A

One Consumer Spends money
1st step increases income of the business

then biz spends money w/ supplier So their income increases

Increases in Tax Revenue for Gov.

Q

ELASTIC DEMAND: what happens with each?

  • price and revenue
  • substitutes
  • considered elastic?
  • Ex: Solve: if Demand drops 10% and Price goes up 8%
A
  • Price Up then Revenue Down
  • Price Down then Revenue Up
  • MANY substitutes (luxury items)
  • considered elastic if > 1

10% / 8% = 1.25 then it’s Elastic

Q

INELASTIC DEMAND: what happens with each?

  • price and revenue
  • remember?
  • substitutes
  • considered inelastic?
  • Ex:Solve: Demand drops 5% and Price goes up 10%
A
  • Price Up then Revenue Up
  • Price Down then Revenue Down
  • Remember that “Income = Inelastic”
  • FEW substitutes (gasoline)
  • Considered Inelastic if < 1

5% / 10% = .5 Inelastic

Q

Income Elasticity of Demand

A

% of Change Qty. Demand / % of Change Income

  • Normal Goods > 1 (demand increases more than income)
  • Inferior Goods < 1 (demand increases less than income)

34
Formula: Disposable Income
Personal Income - Personal Taxes
35
Formula: Return to Scale
% Increase in Output / % Increase in Input • > 1 Increasing returns to Scale • < 1 Decreasing returns to scale
36
Recession
GDP Growth negative 2 consecutive quarters
37
Depression
* prolonged severe Recession w/ high unemployment rates | * No requisite period of time for the economy to officially be in a depression (no defined time)
38

- People are changing jobs or entering the workforce (NORMAL aspect of Full Employment) - Ex: Recent College Graduate is looking for a Job
45
Structural Unemployment
- A worker's job skills Do NOT match those necessary to get a job (they need Education/ Training) - A construction worker wants to work in a office, so they quit their job and get Computer Training
46
What is Unemployment's relationship to Inflation ?
High Unemployment = Low Inflation (vice verse)
47
What is the "Discount Rate?"

50
What is the "Nominal Rate?"
Rate that uses current prices
51
What is the "Risk-free Rate?"
* Rate for a loan w/ 100% certainty of payback (usually results in a low or rate) * Ex: U.S. Treasuries
52
Money Supply - M1
Currency, Coins, and Deposits
53
Money Supply - M2
Highly liquid assets
54
Gov. and Economy - Deficit Spending
* Increased spending levels w/o increased tat revenue * Lower taxes w/o decrease in Spending * Gable that the Multiplier Effect will takeover and boost economy
55
Gov. and Economy - Government Securities
Money Supply can be controlled by the Fed's buying I selling of government securities Ex: Gov. BUYS securities, want to Grow economy, this ADDs money (gives banks more to loan = consumers more to spend) Gov. SELLs securities, takes money out of the economy (slows down inflation)

58
International Trade: Quota
Limit on number of imported goods
59
International Trade: Good for Domestic Producers
* Demand Curve shifts RIGHT * Fewer substitutes * Charge higher prices
60
International Trade: Bad for Foreign Producers
* Demand curve Shifts LEFT * Fewer buyers * Charge lower prices
61
International Trade: Good for Foreign Consumers
* Supply curve shifts RIGHT | * Goods purchased at Lower prices
62

* Supply curve Shifts LEFT | * Fewer goods bought due to higher prices
