Adverse Selection and Moral Hazard
Giant Pool of Money
• Subprime mortgage:
– Loans
• No income no asset loan:
– Adverse Selection or Moral Hazard?
• Adverse Selection
– It describes a situation wherein an individual's demand for
insurance (the propensity to buy insurance and the quantity
purchased) is positively correlated with the individual's risk
of loss (higher risks buy more insurance), and the insurer is
unable to allow for this correlation in the price of insurance.
• Moral Hazard
– In economics, moral hazard occurs when one person takes
more risks because someone else has agreed to bear the
burden of those risks.
