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 increases - 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 - price of beef rises- so people buy more chicken

Future price increase is expected - War in Middle East- people go out and buy gas

Market expands - i.e. 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 - price of beef goes up- less demand for ketchup

Boycott - Company commits social blunder- consumers boycott

Consumer income rises - 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
