• a. Complete the table.
• b. What level of output should the firm produce to maximize profits?
• c. Assume this firm is making a loss when it produces its 7th unit of output. What should the firm do in the short-run? Should it operate at loss or shutdown in the short run?

3. How does the profit maximization condition for a monopoly differ from that for a perfectly competitive firm? How does this difference impact efficiency under each market structure? Explain.

4. The following table provides market share information about the soft-drink industry. Review antitrust laws and the merger guidelines under “Chapter 15: Monopoly and Antitrust Policy” and conduct your own research on U.S. anti-trust laws to answer the following questions.

The demand curve faced by a perfectly competitive firm contrasts significantly with the market demand curve within the same market. In a perfectly competitive market, individual firms face a horizontal demand curve at the level of the market price. This occurs because each firm’s output is so small relative to the market that it cannot influence the price; thus, the firm is a price taker. The market demand curve, however, is downward-sloping, reflecting the total quantity demanded by all consumers at various price levels. The key difference lies in the individual firm’s demand being perfectly elastic, coinciding with the market price, while the overall market demand includes consumers' willingness to pay different prices at varying quantities (McConnell, Brue & Flynn, 2020). This distinction emphasizes that individual firms do not set prices but accept the prevailing market price determined by overall supply and demand conditions.

For the second question, considering the provided costs and market price of $140, the completion of the table requires computing total revenue (TR), total cost (TC), and profit or loss for each level of output. At zero output, costs are $90 (fixed costs), and total revenue is zero, leading to a loss equal to fixed costs. As output increases, total revenue is calculated as the product of the quantity and the market price ($140). Total cost is the sum of fixed and variable costs at each output level.

Calculations reveal that the firm maximizes profit—or minimizes loss—by producing at the output where marginal cost equals marginal revenue (price in perfect competition). Once the cost-benefit analysis indicates that, beyond a certain quantity, costs surpass revenue, production should be halted. Typically, the firm should produce up to the point where marginal cost equals marginal revenue, which aligns with the profit-maximizing output. If at the 7th unit of output the firm incurs a loss, and if variable costs are covered by revenues, it might still operate in the short run. However, if variable costs are not recovered, the firm should shut down to minimize losses (Pindyck & Rubinfeld, 2017).

The profit maximization condition diverges notably between monopoly and perfect competition. In perfect competition, firms maximize profit where price equals marginal cost (P=MC). In contrast, a monopolist maximizes profit where marginal revenue equals marginal cost (MR=MC), where marginal revenue is less than price due to the downward-sloping demand curve. This deviation results in monopolies producing less and charging higher prices than perfectly competitive markets—leading to allocative inefficiency and deadweight loss (Varian, 2019). The monopoly’s ability to restrict output reduces overall economic welfare, whereas perfect competition achieves maximum efficiency in resource allocation.

The market share data for the soft-drink industry illustrates a concentration that can be evaluated through the Herfindahl-Hirschman Index (HHI). The HHI sums the squares of individual market shares; a higher HHI indicates a more concentrated market. Calculations show that merging Coca-Cola (37%) and Pepsi-Co (35%) results in an HHI of:

HHI = 37^2 + 35^2 + 17^2 + 11^2 = 1369 + 1225 + 289 + 121 = 2992

According to U.S. antitrust guidelines, a market with an HHI above 2500 points to a highly concentrated market. The merger of Coca-Cola and Pepsi-Co would push the HHI well beyond this threshold, potentially raising competitive concerns and prompting scrutiny for monopolistic tendencies. Such a merger would likely be considered highly concentrated, affecting market competitiveness and raising ethical questions regarding market dominance (U.S. Department of Justice & Federal Trade Commission, 2010).

The approval of mergers between the top companies depends on whether they significantly increase market concentration and impede competition. Given the high combined market share and HHI, regulatory authorities such as the Department of Justice and FTC would probably scrutinize such mergers intensively. A merger between Coca-Cola and Pepsi-Co, or similar combinations, could be challenged or prevented depending on their potential to create monopolistic power and reduce consumer choices (Kovacic & Shapiro, 2019).

Barriers to entry in the soft-drink sector include substantial capital requirements for marketing and distribution, established brand loyalty, economies of scale, and extensive distribution networks. These factors create high entry costs and make market entry difficult for new competitors, leading to reduced competitive pressure and increased market power for existing giants (Lapan & Wace, 2010).
