3 WHY HEALTH CARE IS NOT JUST ANOTHER GOOD 3

4 WHY HEALTH CARE IS NOT JUST ANOTHER GOOD Rapid increases in quality (which get confused as price increases) Treatments developed in the 1990s for AIDS are expensive but this is a quality increase, not a price increase 3

5 WHY HEALTH CARE IS NOT JUST ANOTHER GOOD Rapid increases in quality (which get confused as price increases) Treatments developed in the 1990s for AIDS are expensive but this is a quality increase, not a price increase Consumers have less knowledge about what they are buying than they typically do when buying goods. 3

6 WHY HEALTH CARE IS NOT JUST ANOTHER GOOD Rapid increases in quality (which get confused as price increases) Treatments developed in the 1990s for AIDS are expensive but this is a quality increase, not a price increase Consumers have less knowledge about what they are buying than they typically do when buying goods. We value it as a society: we hate the idea that people may die when a treatment is available. View health care like a right. 3

We value it as a society: we hate the idea that people may die when a treatment is available. View health care like a right. It is generally financed by firms for somewhat strange reasons 3

15 INSURANCE Lets forget about health care for a little while and think about insurance more generally 10

16 INSURANCE Lets forget about health care for a little while and think about insurance more generally What is insurance? 10

17 INSURANCE Lets forget about health care for a little while and think about insurance more generally What is insurance? I am worried about something bad happening (health shock, house burns down, wife dies, car accident) 10

18 INSURANCE Lets forget about health care for a little while and think about insurance more generally What is insurance? I am worried about something bad happening (health shock, house burns down, wife dies, car accident) Basically insurance works the following way: - I pay something to the insurance company every month - If something bad happens the insurance company gives me money 10

I am worried about something bad happening (health shock, house burns down, wife dies, car accident) Basically insurance works the following way: - I pay something to the insurance company every month - If something bad happens the insurance company gives me money Why do people do this? - We think they are Risk Averse-that is we like our income to be smooth 10

20 INSURANCE Lets forget about health care for a little while and think about insurance more generally What is insurance? I am worried about something bad happening (health shock, house burns down, wife dies, car accident) Basically insurance works the following way: - I pay something to the insurance company every month - If something bad happens the insurance company gives me money Why do people do this? - We think they are Risk Averse-that is we like our income to be smooth But then why do insurance companies do this? - They insure enough people that they don t really face risk, some people collect but most do not 10

21 MORAL HAZARD 11

22 MORAL HAZARD There are two major problems with insurance, the first is moral hazard 11

23 MORAL HAZARD There are two major problems with insurance, the first is moral hazard Moral Hazard: the fact that having insurance increases 11

24 MORAL HAZARD There are two major problems with insurance, the first is moral hazard Moral Hazard: the fact that having insurance increases the demand for the good 11

25 MORAL HAZARD There are two major problems with insurance, the first is moral hazard Moral Hazard: the fact that having insurance increases the demand for the good Think about car insurance: 11

26 MORAL HAZARD There are two major problems with insurance, the first is moral hazard Moral Hazard: the fact that having insurance increases the demand for the good Think about car insurance: I will not drive as carefully because I don t need to worry about buying a new car 11

27 MORAL HAZARD There are two major problems with insurance, the first is moral hazard Moral Hazard: the fact that having insurance increases the demand for the good Think about car insurance: I will not drive as carefully because I don t need to worry about buying a new car I may get a scratch on my bumper but get a whole new bumper 11

28 MORAL HAZARD There are two major problems with insurance, the first is moral hazard Moral Hazard: the fact that having insurance increases the demand for the good Think about car insurance: I will not drive as carefully because I don t need to worry about buying a new car I may get a scratch on my bumper but get a whole new bumper I may crash my car on purpose to get a new car 11

29 MORAL HAZARD IN HEALTH INSURANCE Health insurance has some of these issues I will not do as much to take care of myself because I don t need to worry about cost I may go to the doctor with a small problem At hospital I may want expensive tests that I wouldn t pay for myself However, probably wouldn t actually make myself sick to get insurance We need to put things into health insurance contracts to help reduce this problem Lets see it in a picture 12

30 Price Amount of Health Care 13

31 Price Suppose this were the supply and demand if people paid for health insurance themselves once they were sick Amount of Health Care 13

32 However, once they are perfectly insured what will they choose? Price Suppose this were the supply and demand if people paid for health insurance themselves once they were sick Amount of Health Care 13

33 However, once they are perfectly insured what will they choose? Price Amount of Health Care 13

34 However, once they are perfectly insured what will they choose? Consumers actually don t really like this, it is nice once they get sick but it makes insurance too expensive Price Amount of Health Care 13

35 However, once they are perfectly insured what will they choose? Consumers actually don t really like this, it is nice once they get sick but it makes insurance too expensive Price Note that once again if demand were inelastic this wouldn t be a problem Amount of Health Care 13

37 VOCABULARY OF INSURANCE 14

38 VOCABULARY OF INSURANCE Deductible the amount of health spending a year that you have to pay before the insurance company pays anything 14

39 VOCABULARY OF INSURANCE Deductible the amount of health spending a year that you have to pay before the insurance company pays anything Co-payment either a set amount or the percentage of the bill after the deductible has been taken out that you have to pay 14

40 VOCABULARY OF INSURANCE Deductible the amount of health spending a year that you have to pay before the insurance company pays anything Co-payment either a set amount or the percentage of the bill after the deductible has been taken out that you have to pay Maximum out-of-pocket the most that a person or family will have to pay over a year for all covered health expenses 14

41 VOCABULARY OF INSURANCE Deductible the amount of health spending a year that you have to pay before the insurance company pays anything Co-payment either a set amount or the percentage of the bill after the deductible has been taken out that you have to pay Maximum out-of-pocket the most that a person or family will have to pay over a year for all covered health expenses Lifetime maximum the most that an insurance company will pay on your health expenses over your lifetime 14

42 WHY CO-PAYMENTS INCREASE PRICES Third-Party Payer: an entity other than the consumer pays part of the costs If people only pay 50% of a price they will consume much more Lets see this in a picture 15

43 Copayment: lets think about what happens with copayments Price Suppose copayment is 50%, now when price is $100 I act like it is $50 16

44 Copayment: lets think about what happens with copayments Price Suppose copayment is 50%, now when price is $100 I act like it is $50 16

45 Copayment: lets think about what happens with copayments Price Suppose copayment is 50%, now when price is $100 I act like it is $50 16

46 Copayment: lets think about what happens with copayments Price Suppose copayment is 50%, now when price is $100 I act like it is $50 Better but not perfect, are there other things we can do to keep costs down? 16

47 TYPES OF INSURANCE PLANS Fee-for-service Health Maintenance Organization (HMO) Preferred Provider Organization (PPO) 17

48 CONTROLLING EXPENSES HMO s and PPO s use Primary Care Physicians (PCP s) or Gatekeepers who are physicians charged with making the initial diagnosis and making referrals 18

49 ADVANTAGES AND DISADVANTAGES OF INSURANCE TYPES Insurance Type Fee-for- Service HMO Advantage 1) Maximum physician choice 2) Little insurance company meddling in doctors decisions Maximum control over expensive and unnecessary procedures so premiums, deductibles and co-payment rates are low. Disadvantage Highest premiums, deductibles, and co-payment rates because of little control over expensive and unnecessary procedures 1) Minimal physician choice 2) Significant meddling in physician decisions, especially when differing procedures have significant cost differences PPO 1) Some physician choice 2) moderate premiums, deductibles and co-payment rates 3) some control over expensive procedures 4) minor meddling in physician decisions 19

50 THE HMO DEBATE To control costs, HMOs use rules to limit expenses. E.g. recuperating time in a hospital is limited for births. These rules sometimes conflict with doctors wishes for their patients. With patients having little interest in controlling costs, HMOs rely on rules to control costs. 20

51 ADVERSE SELECTION The other major problem in insurance is adverse selection This occurs when the people who choose to insure themselves are particularly risky-this is a problem for everyone else To see this lets suppose we are insuring ourselves against some event (say wisdom tooth replacement) There are two types of people 21

52 Type Probability of Operation Willingness to Pay Population Probability A 100% $ % B 10% $150 90% So what happens if insurance company doesn t know who is A and who is B? If everyone buys insurance for each person the average payoff the insurance pays out is:.10x$ x0.1x$1000=$100+$90=$190 The insurance company would be willing to offer insurance for $190 However type B people are not willing to pay this, thus none of them buy it But if only type A buy it the average payoff is $1000 This isn t really insurance, the market breaks down 22

53 ADVERSE SELECTION AND HEALTH INSURANCE This is potentially a big problem with health insurance if we just bought it on the market like bacon People who are likely to be sick sign up making it prohibitively expensive for those who are generally healthy This makes it more expensive for insurance company, leading them to raise premiums, leading to an even more selected group This would be particularly problematic if we allowed for pre-existing conditions In some ways this isn t insurance-it is just buying the good 23

54 SOLUTIONS TO ADVERSE SELECTION IN HEALTH INSURANCE In practice tax code is such that employers make health insurance available to all of their employees: this is a way of making sure everyone is in the pool Kind of works for people at the firm Big problem for people who don t have a job Real complication when somebody loses their job-particularly if they are sick Maybe adverse selection isn t a problem at all Public Insurance-have government worry about it and everyone is insured Individual Mandate: it might be unconstitutional but there is some economics behind it 24

55 THE REST OF THE WORLD Most of the industrialized world uses a single-payer system where the government collects (usually very high) taxes to pay for everyone s health care 25
