The term “Risk Premium” in finance and economics denotes the additional return an investor expects to receive from an investment over and above the risk-free rate as compensation for taking on additional risk.
Historical Context
The concept of Risk Premium has evolved alongside financial markets. Originally, early economists such as Adam Smith hinted at the need for additional return for risk. However, modern finance formalized the concept with the development of the Capital Asset Pricing Model (CAPM) by William Sharpe in the 1960s.
Types/Categories of Risk Premium
- Equity Risk Premium: The extra return investing in stocks provides over a risk-free asset.
- Credit Risk Premium: Additional return an investor receives for holding a bond with default risk.
- Liquidity Risk Premium: Extra yield on securities that are not easily converted to cash without significant loss of value.
- Maturity Risk Premium: Extra yield on longer-term bonds due to increased sensitivity to interest rate changes.
Key Events
- 1960s: Introduction of CAPM by William Sharpe and others.
- 1980s-2000s: Various empirical studies to quantify Risk Premium in different markets.
- 2007-2008: Financial crisis highlighted the importance of understanding and managing Risk Premium.
Detailed Explanation
Risk Premium represents the compensation investors demand for taking on risk. The risk-free rate is typically represented by government bonds, considered to have negligible default risk. The difference between the expected return on a risky asset and the risk-free rate is the Risk Premium.
Mathematical Models
One prominent model used to explain Risk Premium is the Capital Asset Pricing Model (CAPM):
where:
- \( R_f \) = Risk-free rate
- \( \beta_i \) = Beta of the investment, representing its risk relative to the market
- \( E(R_m) \) = Expected return of the market
- \( E(R_i) \) = Expected return of the investment
