The assignment content discusses peak load pricing, a two-period price discrimination strategy where the natural monopolist charges higher prices during the peak period (e.g., night) and lower prices during the off-peak period (e.g., day). This promotes efficiency by reducing demand when prices are high. However, it may disadvantage firms whose production operations are tied to peak periods, increasing their costs. The article also explores the regulation of natural monopolies, suggesting that while some degree of monopoly is necessary for efficient production, excessive market power can be harmful. Therefore, government regulation is necessary to prevent abuse and ensure socially desirable outcomes.
