Answer to Question 1

Firms in competitive markets are price takers, because all firms in the market
produce identical products and each firm is small relative to the size of the market. Raising prices above this price would result in losing all its sales because consumers perceive the products to be identical. Setting a price below this level would not increase the number of consumers but only result in a decline in revenue.

Answer to Question 2

a) Both perfect competition and perfect price discrimination create efficiency.
b) Consumers receive consumer surplus with perfect competition. However, there is no consumer surplus with perfect price discrimination.
c) Perfectly competitive firms cannot make an economic profit in the long run. A perfectly price discriminating monopoly makes the maximum amount of economic profit.
