2) Income
3) Population
4) Price of substitutes
5) Price of complements
, 6) Expectations

4) Entry or exit of producers
5) Changes in opportunity costs
When market price is lower than equilibrium price > shortage
When market price is above equilibrium > surplus

Suppose a new regulation will be implemented that leads to a subsidy for Firm A for every product
they produce, and similarly, a tax for Firm B for every product they produce.
Which of the following statements is true?
1) Supply of both Firm A and Firm B increases.
2) Supply of both Firm A and Firm B decreases.
3) Supply of Firm A increases and supply of Firm B decreases.
4) Supply of Firm A decreases and supply of Firm B increases.
Speculators may increase total welfare because:
1) They create shortages in markets, which increases prices.
2) They stock in the expectation of shortages that they thereby reduce.
3) They reduce the consumption of scarce goods.
4) They buy up items in advance of falling prices and then sell them short.

Competitive markets
• Firms in competitive markets are price takers
