These questions will help you prepare the review session. We have barely touched the topics
of some of them. We shall go over as many questions as possible in class.
1) The Law of Large Numbers explains why it is unlikely that the actuarially fair premium
for an insurance policy will be the same for a small start up firm as it will be for a large
employer such as a university.
2) Depending on assistance from family and friends to pay for one’s unforeseen medical
expenses is an example of an economic trade-off between consumption today and
3) The ultimate solution for adverse selection is to include everyone in a social insurance
system, similar to what the United States did for the elderly by creating Medicare.
4) The U.S. is unusual in the developed world in that it uses a general tax to fund health
insurance for the elderly.
5) Title XVII of the Social Security Act of 1965 dealt with the problem of adverse selection
in health insurance markets for elderly people.
6) Bill’s employer offers a new health insurance benefit which covers preventive and
cosmetic dental services, including orthodontic care, for employees and their family
members. If Bill knows his children need extensive orthodontic care, he will buy the policy.
This is an example of moral hazard.
7) Bill’s health insurance covers preventive and cosmetic dental services, including
orthodontic care, for employees and their family members. Bill is willing to pay $30 per
month for over the counter teeth whitening strips at the local pharmacy. With his co-pay, he
learns he can pay $25 per month and receive professional teeth whitening services at his
dentist. He chooses to go to the dentist for the service, which costs the insurance company
$75 per month. This is an example of adverse selection.
8) Increasing the ratio of part time instructors to full time professors reflects one of many
ways that universities attempt to reduce costs of its workforce.
9) Bill is an aging snowboard instructor at a local ski resort. All winter, he takes over the
counter pain medication to deal with his aching joints. Each summer, he moves home with
his parents and takes a part time job making minimum wage. This summer, he got qualified
for and enrolled into state government subsidized health insurance. Now he plans to undergo
arthroscopic surgery by the end of the summer to repair his knee. Though this is an
economically rational decision for Bill, it represents a welfare loss to society as a whole.
10) Catastrophic medical expenses are large, infrequent and unpredictable. Risk aversion
explains why people buy insurance which covers such catastrophic events.
11) The primary funding source for the expenses of current Medicare beneficiaries is the
fund current beneficiaries contributed to throughout their lifetime.
12) Medical bills may be paid by any of the following methods except
a) shifting consumption from one period to another.
b) reducing your welfare loss.
d) family or friends.
e) third party insurance companies.
13) Social insurance
a) is not found in the U.S.
b) would most likely provide more extensive coverage for dementia treatments than family
or private savings.
c) is based on actuarially fair premiums.
d) is funded by voluntary contributions from large corporations.
e) does nothing for people who cannot afford to buy insurance or for people excluded from
purchasing insurance (e.g., people with disabilities).
14) A sudden escalation in the utilization rates and, correspondingly, medical expenditures
for treatment of ischemic heart disease (a procedure usually covered by insurance) would
a) benefit providers.
b) result in Ex Ante moral hazard.
c) reduce welfare loss.
d) benefit insurance companies.
e) increase insurance company profits in the short term.
15) A company with 1,000 employees has the following experience this year
25 hospitalizations at $5,600 each.
24 births at $10,000 each.
4.1 physician visits per employee at $60 per visit.
2.4 prescriptions filled per employee at $25 per prescription.
The actuarially fair premium for this company
a) is less than $500 per employee.
b) is greater than $1000 per employee.
c) is approximately $686 per employee.
d) is less than the loading factor per employee.
e) is the same as the loading factor per employee.
16) The U.S. government subsidizes the private provision of health insurance through
employers. Benefits paid to employees are deductible as expenses by firms, but not
recognized as taxable income by employees. Consider two employees, Ann and Bob, who
work for two different employers. Ann earns $30,000, pays 15% in taxes, and pays $12,000
in premiums for health insurance offered by her employer. Bob earns $40,000, pays 25% in
taxes, and has $12,000 worth of medical bills which he has to pay out of pocket, as Bob’s
employer does not offer health insurance. Which of the following is true about Ann and
a) After paying all taxes and medical bills, Ann and Bob’s incomes available for spending
will be exactly the same.
b) After paying all taxes and medical bills, Ann and Bob’s incomes available for spending
will differ by exactly $10,000.
c) After paying all taxes and medical bills, Ann and Bob’s incomes available for spending
will differ by less than $10,000.
d) After paying all taxes and medical bills, Ann’s income available for spending will be
e) After paying all taxes and medical bills, Bob’s income available for spending will be
17) Many employers in the U.S. pay significant amounts towards their employees’ health
insurance premiums. If the benefit cost per full-time employee rises (e.g. when the insurer
raises premiums) and the employer does not want the total cost of the employees’
compensation (wage + benefits) to rise, all of the following would represent valid options for
the employer to consider, except
a) replacing some full-time employees with part-time workers.
b) laying off some of the full-time employees and instituting mandatory overtime for the
remaining full-time employees (assuming overtime is paid at the same wage rate as regular
c) prohibiting fulltime employees to work overtime and hire temporary part-time workers to
work those extra hours instead (assuming overtime is paid at the same wage rate as regular
d) increasing full-time employee’s contribution towards premiums; not changing wages.
e) not changing full-time employee’s contribution towards premiums; decreasing wages.
18) Insurance coverage of which treatment would likely cause the most problems with moral
a) emergency room services for fractured ankles.
b) hip replacement surgeries.
c) colon cancer screening tests.
d) allergy medicine.
e) services of Neonatal Intensive Care Units (newborn intensive care).
19) Offering insurance coverage through an optional rider would likely cause the most
problems with adverse selection for which condition?
a) concussion treatment.
b) stress reduction counseling for employees.
c) HIV/AIDs treatment.
d) preventive dental examinations.
e) policy covering accidents for children in daycare.
For Questions 20 - 22

demand schedule for chiropractic visits is shown in the table below.
Price, $ per Visit Number of Visits per Month
20) Sahar responds only to her out of pocket payment when deciding how many office visits
to make. Assume Sahar obtains insurance coverage which requires her to pay 20% of the

21) With insurance, at the $50 office visit price, how many of the services Sahar demands
are worth less to her than what they cost?
22) With insurance, at the $50 office visit price, the welfare loss to society due to moral
hazard (if any) in Sahar’s case is
