Insurance Bet Expected Value Interview Questions
Insurance bet expected value interview questions for pricing downside protection, hedges, utility, and variance reduction.
Candidates discussing hedges, insurance, and risk-reduction side payments.
Insurance pays in the bad state
An insurance-style bet is valuable because it offsets downside. Its expected value may be negative while its risk-reduction role is still clear.
Price the protection
Compute the probability-weighted insurance payout, then compare that expected payout with the premium or cost of the protection.
Concrete example
If protection pays 10 when a 5 percent downside event occurs, the expected payout is 0.5. Paying more than 0.5 is negative EV under a risk-neutral toy model.
Utility can justify protection
A candidate can mention that a risk-averse decision maker may accept negative expected value to reduce a painful tail loss, if the prompt allows utility reasoning.
Distinguish hedge from profit bet
A hedge can be useful because it changes the distribution of outcomes, not because it necessarily has positive expected value on its own.
Common mistakes
Candidates often call insurance bad just because it is negative EV. The stronger answer separates risk-neutral EV from utility and risk constraints.
