Title: The role of government in health care


1
The role of government in health care
  • Today Reasons for having government-provided
    health care Medicare Medicaid Reform efforts

2
Previously
  • We saw that health care costs (as a percentage of
    GDP) have rapidly increased over the last 50
    years
  • Health care insurance
  • Advantages and disadvantages

3
Today
  • Government-provided health care
  • Why should government provide health care?
  • Programs
  • Medicare
  • Medicaid
  • The governments role in health care reform

4
Why should govt provide health care?
  • Adverse selection
  • Moral hazard
  • Paternalism
  • Income too low for some people

5
Adverse selection
  • Recall adverse selection problem (see example to
    the right)
  • The government could force everyone into the same
    health care plan
  • Pro Adverse selection problems go away
  • Con Low-risk people subsidize high-risk people
  • Example 6 people at a firm
  • Spending if sick 10,000
  • 3 people have a high risk of getting sick
  • 10 each
  • 3 people have a low risk of getting sick
  • 5 each
  • With no employer contribution, some at low risk
    do not buy insurance

6
Moral hazard
  • Some activities are more likely to occur to an
    insured person
  • Bungee jumping
  • Mountain climbing
  • Skydiving
  • Smoking?
  • Bad eating habits?
  • These activities lead to inefficient outcomes
  • The government can intervene to try to discourage
    these things from occurring
  • Anti-smoking campaigns
  • Commercials promoting good eating habits
  • Prohibiting certain very dangerous activities
  • Withholding care due to dangerous activities

7
Paternalism
  • A paternalist would argue that some people dont
    get it right when it comes to health insurance
  • These people would say that everyone should be
    forced to have a minimum level of health care
  • Much of the 2008 presidential debate involved
    paternalistic arguments

8
Income too low for some people
  • Some people do not make enough money to afford
    health care
  • Problem made worse by increasing health care cost
    (see Downward spiral at right)
  • Young adults and noncitizens make up a
    substantial fraction of the uninsured in the US
  • Downward spiral
  • Health care costs go up
  • More people are unable to afford health insurance
  • These people must use the Emergency room, driving
    up premiums for those insured
  • When premiums go up due to increased numbers in
    the Emergency room, the cycle repeats

9
What does the government do?
  • The government provides over 45 of health care
    funds in the United States
  • Two main programs of government-provided health
    care
  • Medicare
  • People 65 and older
  • Disabled people
  • Medicaid
  • Poor people

10
SOURCE Centers for Medicare and Medicaid Services 2005a.
11
Medicare
  • Enacted in 1965
  • Second largest domestic spending program
  • Funded by a 2.9 percent tax on earnings of
    current workers
  • Tax split evenly between employers and employees
  • Provides health insurance to seniors and the
    disabled, primarily through the private sector
  • Seniors must have worked and paid payroll taxes
    for at least 10 years
  • About 35 million seniors enrolled

SOURCE Centers for Medicare and Medicaid Services 2005a.
13
Different aspects of Medicare
  • Parts A and B of Medicare are the largest
    components
  • Part A Hospital insurance
  • Part B Supplementary medical insurance
  • New Medicare component Part D
  • Prescription drug benefit

14
Cost control measures for Medicare
  • Before 1983, Medicare reimbursement was
    retrospective for Part A
  • Compensation is made after services are completed
  • Little incentive to economize on costs
  • Since 1983, this changed to a prospective payment
    system (PPS)
  • Compensation level is set before services start
  • 500 diagnosis related groups exist for the
    prospective payment system
  • This gives incentives to economize on costs

15
Cost control measures for Medicare
  • Recall DWL that occurs when MB is low
  • PPS appears to have decreased DWL
  • Average stay for Medicare patients in short-stay
    hospitals decreased from 10.5 days in 1981 to 8.5
    days in 1985
  • The decrease in stay appears to have no effect on
    health outcomes

16
Cost control measures for Medicare
  • To keep costs down for Part B, a resource-based
    relative value scale system is used
  • Fees are set per service provided
  • Does not necessarily keep down number of services
  • If fees are set too low, many medical practices
    will not accept Medicare patients
  • Medicare patients would then get low-quality care

17
Cost control measures for Medicare
  • Managed-care options
  • Since 1985, Medicare beneficiaries could enroll
    in HMOs
  • Originally, the HMO received 95 of the average
    amount that the average patient would require
  • Problem Adverse selection Healthier patients
    enrolled in HMOs ? The government was overpaying
    the HMO

18
Cost control measures for Medicare
  • Solution to adverse selection problem
    Risk-adjusted payments to HMOs
  • Reduced HMO enrollment
  • New methods are being tested to try to increase
    HMO enrollment and decrease costs simultaneously

19
Medicaid Overview
20
Medicaid eligibility
  • 1965 Health insurance for recipients of cash
    welfare payments
  • 1980s Children of low-income two-parent
    families became eligible
  • Children can include care to pregnant women
  • 1997 State Childrens Health Insurance Program
  • Allows states to get additional money from
    federal government to reduce number of uninsured
    kids

21
Financing and benefits
  • Federal and state governments share the cost
  • Poor states get higher matching rates than rich
    states
  • Federal government contribution comes from
    general revenues
  • States must offer major services with Medicaid
  • Hospital stays, physician visits, prenatal care,
    vaccines for children

22
Financing and benefits
  • States have some flexibility in program
    administration
  • Example Capitation-based reimbursement is
    allowed
  • Recall that health care provider receives annual
    payment per patient in their care, independent of
    services rendered
  • Some empirical evidence (Duggan 2004) shows that
    forcing people into managed care increased
    Medicaid costs
  • Questionable if the causation implied is actually
    true
  • Other relevant factors may be missing, leading to
    bias

23
Medicaid stigma
  • Many people do not enroll in Medicaid
  • Guilty feelings
  • Stigmas
  • Uninformed about benefits
  • Public service announcements help to get more
    eligible children on Medicaid

24

25
Are Medicaid expansions effective?
  • Unclear for two reasons
  • How much is due to crowding out?
  • Many eligible people do not enroll in Medicaid
  • Cutler and Gruber (1996) estimate that about half
    of new Medicaid enrollment previously had private
    insurance
  • Card and Shore-Sheppard (2004) estimate that
    crowding out occurs less than Cutler and Gruber
    estimate
  • They also find that take-up rates due to
    expansion are low

26
Another issue Job lock
  • Job lock
  • If a new job does not offer insurance due to a
    pre-existing condition, the worker will stay at
    the old job
  • Health Insurance Policy Portability and
    Accountability Act of 1996 (Kennedy-Kassenbaum
    Act)
  • Provides provisions to reduce job lock
  • Mixed success

27
Health care reform
  • Why is health care reform a hot topic?
  • Increased costs
  • Significant portion of population without
    insurance
  • Increases cost to others
  • Two parts to discuss here
  • Some questions about possible reforms
  • What has actually been passed?

28
Health care reform
  • Some proposals to try to solve the health care
    problem
  • Mandating everyone to have insurance
  • Hot topic in the 2008 Presidential race
  • Catastrophic insurance
  • Only provides payment when expenses become large
  • Health Savings Accounts can be used to pay for
    this type of insurance
  • Nationalized health care
  • Consumer-driven health care (CDHC)

29
Nationalized health care reform
  • Pros
  • Everybody is covered
  • Commodity egalitarianism
  • No adverse selection problems
  • Government can use cost-cutting measures to
    prevent care with low MB
  • Cons
  • Predetermined budget may lead to a suboptimal
    amount of health care provided
  • Long lines in some cases
  • Government determines what is medically
    necessary
  • New technology may not be adopted quickly
  • Moral hazard problems

30
What is CDHC?
  • Recall inefficiencies of providing coverage for
    basic services
  • Over consumption of medical services
  • Deadweight loss
  • CDHC advocates health insurance to be like other
    types of insurance
  • Covers truly catastrophic events
  • High deductibles
  • Shoppers can shop many companies, not just what
    is offered by employer

31
CDHC example
  • Recall we have seen this type of example already
  • Provide a yearly fund to each person or family
  • Carries over to the following year if not used
  • After the yearly fund is used, up to 5,000 of
    expenses must be made out-of-pocket
  • After out-of-pocket expenses are paid, 90 of
    expenses are covered
  • Insurance for years with truly high expenses

32
CDHC reform
  • Pros
  • Reduces deadweight loss by letting consumer pay
    full cost of health care
  • Increased competition by allowing consumers to
    shop around
  • Cons
  • Unhealthy people could be priced out of the
    market due to high risk
  • Most consumers are unable to make completely
    informed decisions about health care
  • Routine exams and immunizations with high levels
    of positive externalities may be forgone

33
Is there a solution?
  • Is there a solution to the health care problems
    presented over the last week?
  • There will probably never be a complete solution
  • Security and efficiency will be at odds with
    each other
  • Some people will always choose NOT to have
    insurance unless forced to
  • Current trend More middle-class Americans are
    deciding to have little or no insurance ?
    This increases health care insurance
    premiums for those that remain insured ? Downward
    spiral

Changes coming from the 2010 Reform Law soon
34
Is there a solution?
  • What if we are willing to accept new ways for
    health care and insurance to be administered?
  • We will likely be able to increase security
    without giving up efficiency
  • Catastrophic insurance may be most important at
    reducing risk
  • Higher deductibles, co-payments, and co-insurance
    rates can decrease loss of efficiency

35
Is there a solution?
  • Is prevention the key?
  • Should people be encouraged to eat healthy?
  • Should healthy food be subsidized?
  • Should unhealthy food be taxed?
  • Are taxes on smoking and alcohol set at the
    optimal level?
  • Should some drugs be legalized, taxed, and
    regulated?
  • Tax money can be used for health care costs

36
Some parts of the reform package
  • Another part of the solution General
    requirement to have health insurance
  • Most firms must provide the option
  • Most Americans would be required to buy coverage
  • Fairness issue Increased pooling
  • Companies are prevented from denying coverage due
    to pre-existing conditions

37
What will the reforms lead to?
  • Fewer downward spirals
  • Lower frequency of insured people paying
    uninsureds costs ? Possible reduction in
    insurance premiums
  • Probable net increase in use for services
  • Many more routine visits
  • Fewer ER visits

38
What is still needed?
  • Ways to deal with DWL due to not paying full cost
  • Policies to increase efficiency are needed
  • Figuring out how to pay for these reforms
  • Value added tax (VAT) needed?
  • Dealing with the high costs of the retiring Baby
    Boom generation

39
Summary
  • The government provides health care insurance for
    millions of Americans through Medicare and
    Medicaid
  • Some believe that every person should be able to
    access needed health care
  • Adverse selection and moral hazard are
    significant problems
  • Health reform efforts try to increase medical
    coverage
  • Paternalistic issues and efficiency are at odds
    with each other

Next lecture
  • Social Security
  • Chapter 11
  • Read pages 227, 231-235, and 239-250
  • History
  • Current structure
  • Long-run problems due to the graying of America
  • How peoples decisions differ with and without
    Social Security

41
Problem
  • Timothy has the following utility function
  • U(x, y) x (10,000y)½
  • x denotes Timothys consumption on everything
    except health care
  • y denotes Timothys consumption on health care
  • Note We assume no disutility from work

42
Problem
  • Timothy is currently working 1,500 hours per year
  • Hourly wage is 10
  • He also receives government health care, valued
    at 3,000 per year
  • Timothy could work a second job for 700 hours per
    year
  • Hourly wage is 8
  • With the second job, Timothy would make too much
    money for government health care

43
Problem
  • What should Timothy do?
  • We need to find Timothys highest possible
    utility working one job
  • working both jobs

44
Problem Working one job
  • Total wages 15,000
  • Total government health care 3,000
  • Total benefits 18,000
  • How does Timothy maximize utility if he has
    18,000 in total benefits?
  • Note that at least 3,000 must go to health care
  • Maximize x (10,000y)½ subject to x y 18,000
    and y 3,000

45
Problem Working one job
  • Maximize x (10,000y)½ subject to
  • x y 18,000 and y 3,000
  • For now, ignore y 3,000
  • Maximize x (10,000y)½ subject to
  • x y 18,000
  • Equivalent to Maximize 18,000 y (10,000y)½
  • First order condition
  • 1 10,000½ / 2y½ 0
  • y 2,500
  • Since Timothy would only want 2,500 in care, he
    is constrained to take at least 3,000

46
Utility from working one job
  • Utility when x 15,000 and y 3,000
  • 15,000 (10,000 3,000)½ 20,477

47
Working two jobs
  • Wages
  • 15,000 from first job
  • 5,600 from second job
  • 20,600 total

48
Working two jobs
  • Timothys maximization problem
  • Maximize x (10,000y)½ subject to x y 20,600
  • Notice that x and y only need to be nonnegative
    here
  • Maximize 20,600 y (10,000y)½
  • First order condition is the same as with one job
  • y 2,500

49
Working two jobs
  • What is Timothys utility if he works both jobs?
  • He spends 2,500 on health care
  • He has 18,100 left for everything else
  • Utility is 18,100 (10,000 2,500)½ 23,100

50
What should Timothy do?
  • Utility from one job 20,477
  • Utility from both jobs 23,100
  • Timothy should work the second job and give up
    his government health care
