Opportunity and Sunk Costs
Cost concepts that help finance readers separate forward-looking trade-offs from unrecoverable past spending.
Profit, cost, rentier, sunk-cost, and opportunity-cost terms relevant to capital allocation.
Profit, Cost, and Capital Allocation covers economic theory, expectations, incentives, agency problems, information frictions, behavioral finance, profit, cost, and capital-allocation concepts used in finance.
Use these pages when a theory term helps explain investor behavior, policy credibility, market efficiency, pricing frictions, corporate decisions, or model assumptions. It sits inside Economic Theory and Behavior, so readers can move up when the broader economics context matters.
This landing page points readers toward Opportunity and Sunk Costs, and Profit Concepts and Economic Rents. Choose the narrower page when the term changes the evidence source, calculation, institution, market convention, risk exposure, or decision being made.
