This branch keeps theory terms only when they help explain investment behavior, incentives, information problems, capital allocation, or financial decision-making.

In this section

• Behavioral Finance and Allocation Efficiency

    Expectations concepts used to evaluate policy credibility, model behavior, and forward-looking market assumptions.
    • Adaptive Expectations: Economic Theory for Predicting Future Values
      Adaptive Expectations is an economic theory that hypothesizes how people predict future values based on past observations. Commonly used in macroeconomic models to forecast inflation, interest rates, and other financial metrics.
    • Exogenous Expectations: A Key Concept in Economics
      Exogenous expectations refer to expectations that are not determined by the parameters of the economic system and are not systematically revised. These expectations play a crucial role in economic models and decision-making processes.

      An in-depth explanation of Rational Expectations in Economics, its implications, and comparisons with related terms.
  • Expectations in Inflation and Money Models
    Inflation and money-model concepts where expectations affect real rates, purchasing power, and policy transmission.

      The Real Balance Effect is a fundamental economic concept explaining how changes in the real value of money balances influence spending behaviors, particularly during periods of inflation and deflation.
• Information, Agency, and Market Frictions
  Agency, adverse-selection, asymmetric-information, and principal-agent terms used in finance.
  • Adverse Selection: Definition, Mechanisms, and The Lemons Problem
    In-depth exploration of adverse selection, its mechanisms, and how it relates to the Lemons Problem in insurance and economic transactions.

    An in-depth exploration of the agency problem, where management's interests diverge from those of shareholders, including historical context, types, key events, mathematical models, and mitigation strategies.
  • Asymmetric Information in Economics: An In-Depth Explanation
    Explore the concept of asymmetric information in economics, where one party to a transaction possesses more or superior information compared to another, and its implications on markets and decision-making.
  • Principal-Agent Problem: Causes, Solutions, and Real-World Examples
    An in-depth exploration of the Principal-Agent Problem, its causes, potential solutions, and real-world examples. Understand the complexities and implications of this classic economic and management challenge.
• Profit, Cost, and Capital Allocation
  Profit, cost, rentier, sunk-cost, and opportunity-cost terms relevant to capital allocation.
  • Opportunity and Sunk Costs
    Cost concepts that help finance readers separate forward-looking trade-offs from unrecoverable past spending.
    • Opportunity Cost: What You Give Up When You Choose One Option Over Another
      Opportunity Cost is a finance-focused reference term for market, credit, policy, or investment analysis.
    • Sunk Cost Fallacy: The Result of Misguided Investments
      The Sunk Cost Fallacy is the phenomenon whereby decision-makers continue investing in a project due to the amount already invested, despite new evidence suggesting that the cost will not be recovered.
    • Sunk Cost: Definition and Implications
      Understand Sunk Cost, a financial concept referring to past costs that cannot be recovered and should not influence current decision making. Learn its definition, implications, and how it differs from concepts like opportunity cost.
  • Profit Concepts and Economic Rents
    Economic profit and rent concepts used in capital allocation, competition, and finance-linked microeconomics.
    • Economic Profit: Understanding Surplus Beyond Normal Profit
      Economic Profit: Definition, Calculation, and Comparison with Accounting Profit. Explore how economic profit integrates opportunity cost and why it's crucial for business analysis.
