Question

Examine Monopoly equilibrium.

Answer 1

Monopoly Equilibrium occurs when a monopolist maximizes its profit by producing the output where Marginal Revenue (MR) equals Marginal Cost (MC), and the MC curve intersects the MR curve from below. This ensures the monopolist earns the highest possible profit and not a loss. There are two approaches to finding this equilibrium:

1. Total Revenue and Total Cost Approach: The monopolist fixes different prices and chooses the output at which the difference between total revenue and total cost is maximum.
2. Marginal Revenue and Marginal Cost Approach: The monopolist produces where MR = MC, with MC cutting MR from below.

Short-Run Equilibrium: In the short run, the monopolist can earn supernormal profits, normal profits, or incur losses depending on the relationship between price and average cost at equilibrium output. The monopolist continues production as long as the price covers the average variable cost.

Long-Run Equilibrium: In the long run, unlike perfect competition, the monopolist can sustain supernormal profits due to barriers to entry. The long-run output and price are determined by the equality of long-run marginal cost and marginal revenue, considering demand elasticity and cost conditions.

Outcomes of Monopoly Equilibrium:

• Prices are higher and output lower compared to competitive markets.
• The monopolist often earns supernormal profits.
• Monopoly results in allocative inefficiency and loss of consumer welfare.
