Let's consider the health insurance market. Suppose there are two types of consumers: those with pre-
existing conditions and those without. Those with pre-existing conditions make up 10% of consumers.
All consumers are risk-averse with utility function, U(X)=√X. Those with pre-existing conditions
require medical care 50% of the time. Those without require medical care 5% of the time.
Assume each consumer has an initial wealth of $1000 and medical care costs $500.
If the insurance companies are allowed to sell insurance at different prices to the two types of
consumers and competition forces them to charge the fair insurance premium, consumers without pre-
existing conditions
✓ insurance at a price of $
✓. Consumers with pre-existing conditions
✓ insurance at a price of $
Now suppose the government passes a law that bans discrimination on the basis of pre-existing
conditions. In this case, the insurance companies can no longer offer insurance at two different prices
(they can only charge a single price). In this case, in equilibrium, consumers without pre-existing
conditions
insurance at a price of $
. Consumers with pre-existing conditions
✓ insurance at a price of $
Relative to before the law is passed, consumers without pre-existing conditions are
✓ off. Consumers with pre-existing conditions are
✓ off.
