Case Study 15: Price and Output Determination under Perfect CompetitionGreenFields Agriculture Ltd., a Zambian firm, produces organic maize in a market characterized by perfect competition. Numerous small-scale farmers offer identical maize products, and no single farmer can influence the market price. The current market price for organic maize is ZMW 2.50 per kilogram. GreenFields’ cost structure indicates that the marginal cost (MC) of producing maize equals the market price at an output level of 10,000 kilograms. The firm’s average total cost (ATC) at this output level is ZMW 2.00 per kilogram. GreenFields is contemplating whether to expand production, maintain current levels, or exit the market.
REQUIRED:
Explain why GreenFields Agriculture Ltd. is considered a price taker in this market structure.
Determine the profit or loss GreenFields would incur at the current output level.
Should GreenFields increase production beyond 10,000 kilograms? Justify your answer using marginal analysis.
Discuss the long-run equilibrium condition for firms in a perfectly competitive market and its implications for GreenFields.
If the market price falls below the average variable cost, what should GreenFields’ short-run decision be? Explain.
