The market for electricity in Hamsterville is a natural monopoly. The government of Hamsterville wants to regulate Cricetidae Lighting and Power, the sole producer of electricity in Hamsterville.

Solution
a
Identifying the Natural Monopoly: A natural monopoly occurs when a single firm can supply the entire market at a lower cost than any combination of multiple firms. This is typically due to high fixed costs and economies of scale
b
Understanding the Graph: The graph shows the cost curves (MC, ATC) and demand curves (D, MR) for Cricetidae Lighting and Power. The intersection points of these curves help determine the optimal price and quantity
c
Setting the Price to Reduce Deadweight Loss: To reduce deadweight loss without subsidizing the firm, regulators should set the price where the firm can cover its average total cost (ATC). This occurs at the intersection of the ATC and MC curves, which aligns with P2P_{2} on the y-axis and Q2Q_{2} on the x-axis
d
Conclusion: Therefore, the regulators should set the price at P2P_{2} and the quantity at Q2Q_{2}. This ensures the firm covers its costs and reduces deadweight loss
Answer
(D) P2,Q2P_{2}, Q_{2}
Key Concept

Explanation
In a natural monopoly, setting the price where the firm covers its average total cost (ATC) ensures that the firm remains in business without requiring subsidies, while also reducing deadweight loss.
