21.4 Reinsurance and Market Value
Measure the impact on the value of the firm instead of the impact on capital
Given 2 actions, the one that increases the value the most on a risk-adjusted basis would be preferred
Caveat: We don’t know how this can be done
Currently: we measure value of the stability that reinsurance provides by measuring the reduction in capital
Next step: Measure the value of reinsurance by measuring the \(\Delta\) in the value of the company
Highlights from recent studies
Insureds demand price discounts of 10-20 times the expected cost of an insurer default (EPD)
e.g. 0.5% default, expected cost = 100K if default
\(\Rightarrow\) EPD = 500
\(\Rightarrow\) Discount demand = 500 \(\times\) 10 or 20 = 5-10K
1% decrease in capital \(\Rightarrow\) 1% loss in pricing level
1% increase in \(\sigma_{earnings}\) \(\Rightarrow\) 0.33% decrease in pricing level
Rating upgrades is worth 3% of business growth
Rating downgrades can drop business by 5-20%
