Development & Analysis, Economic Principles (Supply & Demand, Market Failures),
Cost Containment Strategies, Insurance Models (Medicare, Medicaid, Private),
Regulatory Frameworks, Public Health Policy, Ethics & Legal Considerations
Question 1: Which healthcare system model is characterized by government
financing through taxation and government provision of healthcare services, as
exemplified by the United Kingdom's National Health Service?
A. Bismarck model
B. National Health Insurance model
C. Beveridge model
D. Out-of-pocket model
CORRECT ANSWER: C. Beveridge model
Rationale: The Beveridge model, named after William Beveridge, features healthcare
financed by government taxation and delivered by government-employed providers. The
UK's NHS is the canonical example, where services are free at point of use and funded
through general tax revenue, distinguishing it from the Bismarck model (social
insurance), National Health Insurance (single-payer with private providers), or out-of-
pocket systems common in low-income countries.
Question 2: Under the Affordable Care Act (ACA), which provision prohibits health
insurers from denying coverage or charging higher premiums based on pre-existing
conditions?
A. Essential Health Benefits requirement
B. Individual Mandate
C. Guaranteed Issue and Community Rating
D. Medicaid Expansion
CORRECT ANSWER: C. Guaranteed Issue and Community Rating
Rationale: The ACA's Guaranteed Issue provision requires insurers to offer policies to all
applicants regardless of health status, while Community Rating restricts premium
variations to factors like age, geography, and tobacco use—not health status or pre-
existing conditions. This dual mechanism protects high-risk individuals from coverage
denial or prohibitive costs, a cornerstone of the ACA's market reforms.
Question 3: In health economics, what term describes a situation where the
consumption or production of a healthcare service generates benefits or costs for
third parties not directly involved in the transaction?
A. Moral hazard
B. Adverse selection
C. Externality
D. Information asymmetry
CORRECT ANSWER: C. Externality
,Rationale: Externalities occur when a transaction imposes uncompensated benefits
(positive externality, e.g., vaccination reducing community transmission) or costs
(negative externality, e.g., antibiotic overuse fostering resistance) on bystanders. This
market failure justifies policy interventions like subsidies for preventive care or
regulations on antimicrobial use to align private and social incentives.
Question 4: Which Medicare payment model reimburses hospitals a fixed amount
per discharge based on the patient's diagnosis, incentivizing efficiency but
potentially encouraging premature discharge?
A. Resource-Based Relative Value Scale (RBRVS)
B. Diagnosis-Related Groups (DRGs)
C. Capitation
D. Fee-for-service
CORRECT ANSWER: B. Diagnosis-Related Groups (DRGs)
Rationale: Introduced in 1983, Medicare's Inpatient Prospective Payment System uses
DRGs to assign a predetermined payment per hospital stay based on diagnosis,
procedures, age, and complications. This shifts financial risk to providers, promoting
cost containment but creating incentives to minimize length of stay or avoid high-cost
patients, necessitating quality safeguards.
Question 5: What is the primary economic rationale for government intervention in
healthcare markets, according to standard health economics theory?
A. To maximize provider profits
B. To correct market failures such as information asymmetry, externalities, and
inequitable access
C. To eliminate all private insurance options
D. To standardize medical treatments globally
CORRECT ANSWER: B. To correct market failures such as information asymmetry,
externalities, and inequitable access
Rationale: Healthcare markets frequently exhibit failures: patients lack perfect
information about quality (information asymmetry), preventive care generates positive
externalities, and ability to pay shouldn't determine access to life-saving care.
Government intervention—through regulation, subsidies, or public provision—aims to
improve efficiency, equity, and social welfare where unfettered markets underperform.
Question 6: Which provision of the Affordable Care Act established health
insurance marketplaces where individuals and small businesses can compare and
purchase qualified health plans?
A. Medicaid Expansion
B. Health Insurance Exchanges
C. Employer Mandate
D. Medical Loss Ratio requirements
,CORRECT ANSWER: B. Health Insurance Exchanges
Rationale: The ACA created state-based or federally facilitated Health Insurance
Marketplaces (Exchanges) to increase transparency, foster competition, and enable
subsidy eligibility determination. These platforms standardize plan information,
facilitate enrollment, and administer premium tax credits for eligible individuals,
enhancing consumer choice and market efficiency.
Question 7: In the context of healthcare financing, what does the term "moral
hazard" refer to?
A. Insurers selecting only healthy enrollees
B. Patients overutilizing healthcare services because they are insulated from the full
cost
C. Providers inducing demand for unnecessary services
D. Governments underfunding public health programs
CORRECT ANSWER: B. Patients overutilizing healthcare services because they are
insulated from the full cost
Rationale: Moral hazard arises when insurance coverage reduces the marginal cost of
care to the patient, potentially leading to consumption of services whose benefit does
not justify their resource cost. This inefficiency is mitigated through cost-sharing
mechanisms like deductibles and copayments, though these must be balanced against
access concerns for low-income populations.
Question 8: Which U.S. federal program primarily provides health coverage to low-
income individuals and families, jointly funded by federal and state governments?
A. Medicare
B. Medicaid
C. CHIP
D. TRICARE
CORRECT ANSWER: B. Medicaid
Rationale: Medicaid is a means-tested program established in 1965, jointly financed by
federal and state governments, with states administering benefits within federal
guidelines. It covers diverse populations including low-income adults, children,
pregnant women, elderly, and people with disabilities, making it the largest source of
health coverage in the United States.
Question 9: What economic concept explains why preventive services like
vaccinations may be underconsumed in a purely private market?
A. Price elasticity of demand
B. Positive externalities
C. Diminishing marginal utility
D. Opportunity cost
, CORRECT ANSWER: B. Positive externalities
Rationale: Vaccinations generate positive externalities because an individual's
immunization reduces disease transmission risk to others. Since private decision-
makers do not account for these societal benefits, the market equilibrium quantity falls
short of the socially optimal level, justifying public subsidies or mandates to increase
uptake and achieve herd immunity.
Question 10: Which payment methodology assigns a fixed, periodic payment per
enrolled patient to a provider or organization, regardless of service volume, shifting
financial risk to the provider?
A. Fee-for-service
B. Capitation
C. Bundled payment
D. Pay-for-performance
CORRECT ANSWER: B. Capitation
Rationale: Capitation pays providers a predetermined amount per patient per period
(e.g., per member per month), incentivizing efficient resource use and preventive care
to avoid costly interventions. However, it risks under-provision of necessary services if
not paired with quality monitoring and risk-adjustment to account for patient
complexity.
Question 11: The Medicare Modernization Act of 2003 primarily introduced which
major benefit expansion?
A. Long-term care coverage
B. Prescription drug coverage (Part D)
C. Dental and vision benefits
D. Mental health parity
CORRECT ANSWER: B. Prescription drug coverage (Part D)
Rationale: The Medicare Modernization Act established Medicare Part D, providing
voluntary outpatient prescription drug coverage through private plans. This addressed a
significant gap in original Medicare, though its design—including the coverage gap
("donut hole") and reliance on private insurers—has been subject to ongoing policy
debate and subsequent ACA modifications.
Question 12: What is the primary purpose of risk adjustment in health insurance
markets?
A. To increase premiums for high-income enrollees
B. To compensate insurers for enrolling individuals with higher expected healthcare
costs
C. To eliminate deductibles for chronic conditions
D. To standardize provider reimbursement rates
