When producing a piece of luggage, the marginal cost is $92, and the marginal revenue is $81. What is the best action for the respective firm?

Entering the market is not advisable when marginal costs exceed marginal revenues. This option implies starting new production in an unfavorable financial condition, which would likely lead to losses. A firm should only enter a market when expected marginal revenues are anticipated to exceed marginal costs in order to ensure profitability.

Increasing production would exacerbate the financial situation for the firm. Since the marginal cost is already higher than the marginal revenue, producing more units would lead to even greater losses per unit. This choice suggests a disregard for the economic principle of operating at a loss when costs outweigh revenues.

Restarting production implies resuming operations that may not be viable given the current financial metrics. If the marginal cost is still higher than the marginal revenue, restarting production would not change the financial outcome and could lead to further losses. This choice fails to address the need to reassess production levels based on cost and revenue dynamics.
