Learning targets Economics and Financing of Health care systems
1. Is health care really different?
Explain the relevance of health economics
Health economics is a distinct specialty within economics that studies the allocation of
resources to and within the health sector. Its relevance is profound and multifaceted,
particularly because healthcare has become the largest sector of many countries’
economies, and its share of GDP is expected to continue growing.
Health economics provides concepts and tools necessary to understand the difficult trade-
offs involved in organizing the allocation of scarce healthcare resources. These concepts and
tools are vital for informing and improving health policy and health system design.
The relevance is anchored in several key facts:
1. Scarcity and Distribution: Healthcare resources are scarce, produced, and distributed,
just like in other sectors, meaning economic principles apply.
2. Efficiency and Equity: The way healthcare systems are organized economically directly
affects efficiency and equity. Health economics helps ensure value for money, which is an
important task given rising costs.
3. Fiscal Sustainability: Health spending growth can be fiscally unsustainable, crowding out
other necessary public spending (e.g., defense, education), and worsening inequality if not
managed. Health economics helps identify strategies to finance spending growth, such as
implementing higher cross-subsidies to guarantee universal access.
4. Price Sensitivity: Despite the perception that healthcare is unique, economic principles
hold: price and demand matter, as demonstrated by the RAND Health Insurance
Experiment, which showed that higher prices reduce healthcare use.
Analyze the causes and consequences of the expansion of the healthcare sector
The healthcare sector is expanding, with spending growing faster than the overall economy
in most countries. This expansion is driven by a combination of demographic, technological,
behavioral, and structural economic factors.
Causes of Expansion (Cost Pressure)
The continuous expansion of healthcare costs is driven by:
1. Population Ageing: The growing share of older people, especially those aged 80+, is the
most important demographic factor leading to higher demand for care.
2. Medical Science & Technology: Advances in medical science and technology lead to more
available treatments, which are often costly.
3. Shift Toward Chronic Diseases: The increasing prevalence of chronic conditions
necessitates long-term care needs, which contributes significantly to costs.
4. Rising Incomes & Welfare: As incomes and welfare rise, people demand more and better
healthcare.
5. Expansion of Health Insurance Coverage: Increased insurance coverage lowers the
effective cost for patients, leading to moral hazard (overconsumption).
6. Flawed Incentives: Payment and delivery systems often contain flawed incentives (like
FFS), promoting volume over value and contributing to wasteful spending.
7. Baumol’s "Cost Disease": This structural economic factor is particularly relevant.
Healthcare is labor-intensive, and productivity growth in healthcare is slower than in other
industries (e.g., 0.2% in LTC versus 1.8% in the overall economy). Since wages rise across the
,entire economy, healthcare cannot match the productivity gains, causing its costs to rise
relative to other goods and leading to an increasing share of GDP spent on the sector.
Consequences of Expansion
The continued rapid growth in health spending creates significant policy and economic
challenges:
• Fiscal Unsustainability: Uncontrolled growth leads to severe fiscal pressure on
government budgets and household finances.
• Crowding Out: Increasing public health spending may crowd out other essential public
services, such as defense or education.
• Worsening Inequality: If costs are not managed, or if financing relies too heavily on
certain sources, inequality can worsen.
• Economic Harm: Increasing health spending may harm the overall economy, for example,
if higher taxes and/or premiums raise labor costs, thereby potentially decreasing
international competitiveness.
Explain what makes health care different and infer the implications thereof
While resources are scarce in healthcare just as in other sectors, healthcare is not a regular
commodity. As Kenneth Arrow noted in 1963, the health sector has unique structural
characteristics that necessitate non-market solutions, such as risk management and
addressing imperfect information. The combination and sheer number of these unique
features distinguish healthcare from other markets.

,These structural flaws mean that policymakers cannot simply rely on free, unregulated
markets to produce socially beneficial outcomes. Instead, they must navigate between
Scylla (market failure) and Charybdis (government failure), using regulation, subsidies, and
public provision to correct market failures.
2. Demand for health care
Recognize the relationship between the demand for health and health care
The demand for health care is not an end in itself; it only generates utility if it contributes to
the improvement of health or quality of life. Therefore, the fundamental relationship is that
the demand for health care is derived from the demand for health.
Health care is merely one of the inputs in an individual’s broader health production
function, which determines overall health status. Other crucial inputs include schooling,
nutrition, prevention, and safety. Health care is viewed not only as a consumption good but
also as an investment good (in future health).
Identify and interpret basic models of health care demand
Traditional economic models struggle to fully explain health care demand because the
assumptions of consumer sovereignty and perfect information are often violated. Three
basic models are used to interpret demand:

patient’s interest.
Identify the determinants of the demand for health care
According to utility theory, consumer demand for health care is determined by consumers
maximizing utility subject to a budget constraint. The key determinants derived from this
model are:
1. Needs (Health Status): Reflects how sick or healthy a person is. This determines the
position of the indifference curve, as sicker people have a higher need for health care,
shifting their curve outward (they "value" health care more relative to other goods).
2. Wants (Preferences): Individual tastes or priorities for health care versus other goods.
This determines the slope of the indifference curve, showing the rate at which someone is
willing to substitute health care for other goods.
3. Budget (Income): Total resources available for spending. This determines the position of
the budget constraint; higher income shifts the budget line outward, allowing more
consumption of health care and other goods.
4. Prices of Health Care & Other Goods: These determine the slope of the budget line. If
health care becomes more expensive, the line pivots inward, reducing the quantity a person
can afford. Because consumers are often insured, the relevant price is usually the out-of-
pocket price (e.g., co-payments).
5. Provider Influence: Due to the physician's information surplus, the supply side can also
influence demand (supplier-induced demand).
Explain utility theory and its relevance for understanding health care demand
Utility theory is a foundational economic concept that posits consumers are rational actors
who aim to maximize their utility (satisfaction) given their financial limitations (budget
constraint).
Relevance for Health Care Demand:
• Optimal Consumption Bundle: Utility theory is used to illustrate the optimal consumption
combination of health care (HC) and other goods (OG) that a consumer can afford. The
optimal combination occurs where the highest indifference curve (utility line) is tangent to
the budget constraint (budget line).
• Marginal Utility: It assumes that consumers always prefer more above less of the same
good, meaning the marginal utility of consumption is positive.
• Price and Income Effects: The theory demonstrates how changes in prices or income alter
the budget constraint, thereby changing the optimal consumption bundle and explaining
consumer demand responses.
• Limitations: Despite its foundational role, utility theory's assumptions are problematic in
health care: consumers often lack the perfect information or predetermined preferences
necessary for truly rational utility maximization concerning complex medical services. The
concept is, however, essential for deriving the empirically testable concepts of price and
income elasticity.
