Insurance is designed to build portfolios of diversifiable risks and to hedge the systematic risk in these portfolios. |

The CAPM links nondiversifiable risk and return for all assets and recognizes that diversifiable risk can be eliminated. |
|
This source of prepayment was diversifiable for a large pool of independent borrowers. |
|
For those risks that are assumed to be diversifiable, no adjustment has been made. |
|
Banks do face liquidity risk, but in this model it is fully diversifiable within the banking system because all spending is routed through banks. |
|
It is similar to CAPM, in that both models treat idiosyncratic risks as diversifiable and, hence, do not assign a risk premium to them. |
|
Therefore, the systematic component of portfolio risk is unavoidable and only partly diversifiable. |
|
Furthermore, our results suggest that insurance is not a diversifiable asset. |
|
The cost of insuring a diversifiable risk is a simple calculation of the discounted value of expected future damages. |
|
Idiosyncratic risk is diversified away at the portfolio level, while the systematic component of portfolio risk is manifest and only partly diversifiable. |
|
Financial theory identifies diversifiable and non-diversifiable risks. |
