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.
