Historical Context
Hidden action, a concept prominently discussed in economics and finance, refers to actions taken by one party in a transaction that are not observable by the other party. This often leads to a situation known as moral hazard. The term gained significant traction with the development of the principal-agent problem theory in the 1970s.
Key Events and Developments
- 1970s: The principal-agent problem, emphasizing information asymmetry, is formally analyzed.
- 1980s: Advances in game theory and contract theory provide tools to better understand and address hidden actions.
- 2008 Financial Crisis: Demonstrated real-world implications of hidden actions, as risk-taking by financial institutions was not fully observable by regulators and investors.
Types/Categories
- Moral Hazard: Risk-taking by individuals or entities because they do not bear the full consequences of their actions.
- Adverse Selection: Related but distinct issue where one party has better information before a transaction.
Detailed Explanations
Moral Hazard in Finance
In the financial industry, hidden actions can manifest as excessive risk-taking by banks and financial institutions. When these entities know they will be bailed out (due to their size and systemic importance), they may engage in riskier behavior, knowing the downside risk is absorbed by the government or taxpayers.
Principal-Agent Problem
The principal-agent problem occurs when an agent (e.g., company executives) acts in their own interest rather than the interest of the principal (e.g., shareholders). The inability to observe every action of the agent leads to suboptimal outcomes for the principal.
Mathematical Models
Contract Theory Model
Incentive Compatibility Constraint: Ensuring the agent’s utility is maximized by acting in the principal’s interest.
U_A(e) ≥ U_A(e') for all e ≠ e'
Where:
- \( U_A(e) \) is the utility of the agent from effort level \( e \).

Importance and Applicability
- Economics: Helps in designing better contracts and incentives.
- Finance: Essential in understanding risk management and regulatory policies.
- Insurance: Crucial for determining premiums and coverage.
Examples
- Banking: Banks taking excessive risks due to implicit government guarantees.
- Employment Contracts: Performance-based bonuses to align employee actions with company goals.
Considerations
- Observation Costs: Ensuring actions are observable can be costly.
- Incentive Structures: Must be carefully designed to mitigate moral hazard.
Related Terms
- Moral Hazard: Increased risk-taking due to unobservable actions.
- Adverse Selection: When one party has more information than the other.
- Information Asymmetry: Situations where one party has more or better information.
Comparisons
- Moral Hazard vs. Adverse Selection: Both involve information asymmetry, but moral hazard occurs post-contract, while adverse selection occurs pre-contract.
Interesting Facts
- Global Impact: The 2008 financial crisis highlighted how hidden actions in the financial sector could lead to global economic consequences.

Whistleblowers: Employees who expose hidden actions in corporations, leading to regulatory changes and improved corporate governance.
Famous Quotes
- “Sunlight is the best disinfectant.” – Justice Louis D. Brandeis, highlighting the importance of transparency.
Proverbs and Clichés
- “What you don’t know can’t hurt you.” – Ironically countered by the concept of hidden actions.
Expressions, Jargon, and Slang
- Too Big to Fail: Institutions whose failure would cause systemic risk, leading to moral hazard.
- Skin in the Game: Ensuring that decision-makers share in the risk.

Summary
Hidden actions represent a critical concept in understanding the dynamics between parties where one party’s actions are not fully observable by the other. This can lead to moral hazard, impacting various sectors from finance to insurance. Addressing hidden actions involves careful design of incentives and contracts, aiming for transparency and alignment of interests to mitigate risks and achieve optimal outcomes.
