In the used car market, adverse selection creates the lemon problem when
◦ sellers cannot judge buyers' creditworthiness.
◦ buyers believe that sellers will offer only high-priced "good" used cars for sale.
◦ buyers believe that sellers will sell only lemons.
◦ sellers offer warranties on all used cars.
◦ None of these answers is correct because it is moral hazard that creates the lemon problem.
