Chapter 6: Health Insurance
Principles of Health Insurance
The Genesis of Health Insurance
• Government does not play a role in health insurance
• Do you buy health insurance from a private company?
• Risk aversion• How much should a private company charge as a premium?
• Actuarially fair premium
= (% risk)(high medical cost) + (% risk)(low medical cost)
• Expected value

Price Equals Expected Medical Cost

Chance of a $1,000
Medical Bill
Expected Medical Bill
High Cost Person 9% 91% $6,400
Low Cost Person 1% 99% $1,600
Table 6.1: Expected Medical Bills
Pi = (EMC)i
• The price charged to a person will vary with the person’s expected medical costs, not the person’s income.

Chapter 6: Health Insurance
Moral Hazard and Price Responsiveness
Adverse Selection and Asymmetric Information
• Moral hazard: the use of medical care because they know the insurer will pay part of their bill.
• Price responsiveness
• Price elasticity
• Adverse selection: instead of a random sample selecting to enroll, a biased sample with higher medical costs is likely to enroll.
• Asymmetry of information

Chapter 6: Health Insurance
The Impact of Insurance on Efficiency and Redistribution
Optimal redistribution from the healthy to the sick
• Citizens’ preferences on redistribution of resources from the healthy to the sick are complex
Efficiency if there is a positive externality
• A corrective subsidy may increase efficiency
• The socially optimal quantity of health care is greater than the quantity consumed privately
