Q

What are the characteristics of a positive supply curve shift (shift right)?

A
  • Supply increases at each price point.
  • Higher Equilibrium GDP
  • Number of sellers increase: market can get flooded.

Examples: Government subsidies or technology improvements that decrease costs for suppliers

Q

What are the characteristics of a negative supply curve shift (shift left)?

A
  • Supply decreases at each price point.
  • Lower Equilibrium GDP
  • Cost of producing item increases

Examples:
Shortage of gold - so less gold watches are made;
wars or crises in rice-producing countries means there is less rice on the market.

Q

What is a Positive Demand Curve Shift (Shift Right)?

A
  • When demand increases at each price point
  • Price of substitutes go up - e.g. price of beef rises, so people buy more chicken
  • Future price increase is expected - e.g. War in Middle East: long lines at gas pumps
  • Market expands - e.g. people get new free health care plan- demand at clinic rises
  • Expansion - more spending increases equilibrium GDP

Q

What is a Negative Demand Curve Shift (Shift Left)?

A
  • Demand decreases at each price point.
  • Price of complement goes up - e.g. price of beef goes up - less demand for ketchup
  • Boycott - e.g. Company commits social blunder - consumers boycott
  • Consumer income rises - e.g. Demand for inferior goods drops as people have more money to spend
  • Consumer tastes change
  • Contraction - less spending decreases equilibrium GDP

Q

How does spending change due to the multiplier effect?

A

The increase in demand ends up being larger than the amount of additional income spent in the economy due to the multiplier effect.

One consumer spends money, which:

  • Increases the income of a business
  • Increases the income of a vendor
  • Increases income of employees
  • Increases tax revenue

Q

What conditions would indicate Elastic Demand?

A
  • Many substitutes (luxury items)
  • Considered elastic if elasticity is greater than 1

10% drop in demand / 8% increase in price : 1.25 (Elastic)

  • Price increases - Revenue decreases
  • Price decreases - Revenue increases

Q

What conditions would indicate Inelastic Demand?

A
  • Few substitutes (groceries - gasoline)
  • Considered inelastic if coefficient of elasticity is less than 1

5% drop in demand / 10% increase in price = .5 (inelastic)

  • Price increases - Revenue increases
  • Price decreases - Revenue decreases

Q

What is Unitary Demand?

A

Unitary demand means:

  • Total revenue will remain the same if price is increased.
  • Considered unitary if the coefficient of elasticity = 1

Q

How is Income Elasticity of Demand calculated?

A

% Change Quantity Demanded / % Change in Income

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

Q

What happens under Cost-Push inflation?

A
  • Overall production costs increase
  • Supply decreases (shift left)
  • Market equilibrium price increases

Note: Demand-Pull and Cost-Push Inflation BOTH result in market equilibrium price to increase.
