Assumptions for efficient market Numerous consumers Numerous suppliers Consumers search for the quality of care Consumers search for the low price Suppliers compete with each other In the end, efficient market ensures that consumers can purchase quality care at the low cost
28
Information Do consumers (patients) know the quality of care? Do consumers (patients) search for the low cost? Do suppliers (doctors) compete with each other?
29
Asymmetric information Asymmetric information refers to the case that one party to a transaction has information pertinent to the transaction that the other party does not possess Examples The doctor knows more than the patient The insurance purchaser knows more than the insurer Competition is a big issue in light of asymmetric information
30
Health insurance Because the health expenditure is random, risk adverse people would seek to reduce expenditure risk by obtaining health insurance (e.g. dialysis patients) Nonetheless, consumption decisions would be distorted due to health insurance. Consumers would like to use more than they want when facing the lower prices (moral hazard) Also, asymmetric information would patients to conceal personal information---high risk consumers purchase good insurances, and good insurances need to charge a even higher price to cover its costs. In the end, no insurers are willing to offer insurance contract (adverse selection)
33
Externality Consumption externality (e.g. vaccinations) Financial externality Moral externality (access of care)
34
