Final answer:
Trigger words for break-even analysis in a case include discussion of the level of output where cost curves intersect, long-run equilibrium, decisions to continue operating at a loss or shutting down, and hypothetical 'if-then' financial scenarios.
Step-by-step explanation:
In a case analysis, trigger words or sentences that suggest a focus on break-even analysis typically involve discussions around costs, revenues, and the point of balance between them. If a case mentions the level of output where the firm's marginal cost (MC) curve intersects the average cost (AC) curve at AC's minimum point, or if it discusses long-run equilibrium where firms earn zero economic profits (P = MR = MC and P = AC), it is indicating a situation where break-even analysis is relevant.
Another indication is when a case presents the scenario that a firm must decide whether to continue operating at a loss or to shut down. This decision is based on whether the price exceeds the firm's average variable cost and thus whether shutting down or operating below the break-even point (where price equals average cost) loses less money, showing that break-even analysis is crucial.
Additionally, hypothetical 'if-then' statements related to financial decisions, such as specifying the conditions under which a firm should remain in business or cease operations, also suggest applying break-even analysis to determine the outcomes of various scenarios.
