In analyzing firm behavior within an oligopoly, it is essential to understand whether companies act independently or interdependently. Oligopoly, characterized by a few dominant firms in the market, inherently fosters interdependence among firms due to strategic interactions (Varian, 2010). Unlike perfect competition where firms operate independently due to numerous competitors, oligopoly players recognize that their decisions, especially concerning pricing and output, directly affect rivals’ strategies and market outcomes. For example, in the airline industry, decisions made by one airline regarding ticket pricing often prompt counteractions by competitors, illustrating interdependence (Tirole, 1988). This strategic dependence results in firms often watching rivals’ actions closely and making decisions that consider potential responses, which further reinforces the interdependent nature of oligopolistic markets (Stiglitz & Walsh, 2002). Consequently, while firms in an oligopoly might appear to operate independently to some extent, their actions are fundamentally shaped by the anticipated reactions of their competitors, confirming the interdependent behavior characteristic of such markets.

The short-run demand and cost structure of a monopolistically competitive firm reveal important insights about profit maximization. Completing the table involves calculating total revenue (TR), profit or loss, and the respective costs. For each output level, total revenue is derived by multiplying the output quantity by the price, and profit is calculated as TR minus total costs (TC). For example, at an output of 1, TR = 80 (price) * 1 = 80, and TC = FC + VC = 90 + 40 = 130, leading to a loss of 50. Repeating this for each output level allows us to fill in the table (Mankiw, 2014). Typically, the output that maximizes profit occurs where marginal revenue equals marginal cost, or where profit is at its peak — often at a lower or moderate output level in monopolistic competition (Perloff, 2019). Based on the computed profits, the optimal output level is identified, and the decision to operate or shut down hinges on whether the firm can cover its variable costs in the short run (Krugman et al., 2019). If the firm’s revenue exceeds variable costs, it should continue to operate; otherwise, shutdown is advisable.

The game-theoretic scenario involving Wal-World and Tarbo examines strategic decision-making related to adopting new barcode technology. A dominant strategy exists when a player’s best move remains consistent regardless of the opponent’s choice. Assessing whether Wal-World has a dominant strategy involves analyzing the payoff matrix to see if one action yields higher profits regardless of Tarbo’s decision (Fudenberg & Tirole, 1991). If Wal-World’s optimal choice does not depend on Tarbo’s move, then it possesses a dominant strategy. The same logic applies for Tarbo. The existence of a Nash equilibrium depends on whether both companies settle on strategies where neither can improve their payoff unilaterally, given the other’s choice (Myerson, 1991). If such strategy pairs exist, they constitute a Nash equilibrium, representing a stable outcome of the game where both firms’ strategies are mutually best responses. Identifying these conditions requires examining the payoff matrix for these strategic interdependencies.
