17: Pricing and Output Policies in Perfect Competition and Monopoly

In Perfect Competition:

Prices are determined by the market forces of demand and supply. All firms are price takers.
Demand Curve is perfectly elastic. Average Revenue (AR) and Marginal Revenue (MR) remain the same. Price is determined where Marginal Cost (MC) equals Average Cost (AC).

In a Monopoly:

Either price or output is set by the firm. Firm is a price maker. Demand Curve slopes downwards. It is also the market demand curve. Average Revenue (AR) and Marginal Revenue (MR) will fall. Price is determined at a point which is higher than Marginal Cost (MC) and Average Cost (AC).
