How an industry got affected in the short run and adjusts to a new long-run equilibrium when a technological change decreases the marginal cost for every firm in the industry.
b)
Explanation of Solution
The average total cost curve and the marginal cost curve both move lower as marginal costs decline because businesses make money economically in the short term. The profit will eventually draw new competitors into the market due to which with the reduction in market share for each existing firm, the demand curves of those firms move to the left. When each firm's demand curve has moved to the left until it is tangent to the new, lower average total cost curve, long-run equilibrium is once again restored. At this point, the average total cost is just equal to the price charged by each firm, and no profit is made.
Introduction: Monopolistic competition refers to an imperfect competition where multiple manufacturers compete with one another yet sell distinct products that are not exact substitutes. Equilibrium is a situation where price and quantity variables of economic forces are equal to each other.
