Unformatted text preview: revenue and marginal cost, first identify any positive sales quantities at which marginal revenue equals marginal cost. Then check whether the most profitable positive sales quantity results in greater profit than shutting down. If it does, that is the profit­ maximizing choice. If not, then selling nothing is the best option. In this example, the price­taking firm will maximize profit by producing the quantity where price (or marginal revenue) equals marginal cost: 729 = 9Q2 81 = Q2 Q = 9 units. If the firm shuts down, then it incurs a fixed cost of $1,000. Because revenue (P × Q = 729(9) = 6,561) is greater than the variable cost of production (3Q3 = 3(9)3 = 2,187), the firm should not shut down. Next, suppose the fixed cost is avoidable by shutting down. When producing optimally, profit equals: π = P × Q – 3Q3 – 1,000 π = 729(9) – 3(9)3 – 1,000 π = 6,561 – 2,187 – 1,000 π = $3,374. If the fixed cost is avoidable, then shutting down results in a profit of zero. Therefore, the firm should continue producing. That is, the firm should produce 9 units. 8. awar d: 4 out of 4.00 points Noah and Naomi can produce garden benches, garden chairs or both; they are price takers in both markets.
