Health economics is a branch of economics concerned with issues related to efficiency, effectiveness, value and behavior in the production and consumption of health and healthcare. Health economics is important in determining how to improve health outcomes and lifestyle patterns through interactions between individuals, healthcare providers and clinical settings.[2] In broad terms, health economists study the functioning of healthcare systems and health-affecting behaviors such as smoking, diabetes, and obesity.[citation needed]
One of the biggest difficulties regarding healthcare economics is that it does not follow normal rules for economics. Price and quality are often hidden by the third-party payer system of insurance companies and employers. Additionally, QALYs (Quality Adjusted Life Years), one of the most commonly used measurements for treatments, is very difficult to measure and relies upon assumptions that are often unreasonable.[3]
A seminal 1963 article by Kenneth Arrow is often credited with giving rise to health economics as a discipline. His theory drew conceptual distinctions between health and other goods.[4] Factors that distinguish health economics from other areas include extensive government intervention, intractable uncertainty in several dimensions, asymmetric information, barriers to entry, externality and the presence of a third-party agent.[5] In healthcare, the third-party agent is the patient's health insurer, who is financially responsible for the healthcare goods and services consumed by the insured patient.[citation needed]
Health economists evaluate multiple types of financial information: costs, charges and expenditures.[citation needed]
Uncertainty is intrinsic to health, both in patient outcomes and financial concerns. The knowledge gap that exists between a physician and a patient creates a situation of distinct advantage for the physician, which is called asymmetric information.[citation needed]
Externalities arise frequently when considering health and health care, notably in the context of the health impacts as with infectious disease or opioid abuse. For example, making an effort to avoid catching the common cold affects people other than the decision maker[6][7][8]:vii–xi[9] or finding sustainable, humane and effective solutions to the opioid epidemic.
Scope
The scope of health economics is neatly encapsulated by Alan Williams' "plumbing diagram"[10] dividing the discipline into eight distinct topics:
In the third century BC, Aristotle, an ancient Greek thinker, once talked about the relationship between farmers and doctors in production and exchange.[11] In the 17th century, William Petty, a British classical economist, pointed out that the medical and health expenses spent on workers would bring economic benefits.[citation needed]
Presently, contemporary health economics stands as a prominent interdisciplinary field, connecting economic theory with healthcare practice; its diverse sub-disciplines and research domains are evident. The academic roots of this knowledge are commonly traced back to the U.S. tradition.[12]
The American Medical Association (AMA) was created in 1848, having as main goals scientific advancement, creation of standards for medical education, launching a program of medical ethics, and obtaining improved public health. Yet, it was only in 1931 that economic concerns came to the agenda, with the creation of the AMA Bureau of Medical Economics, established to study all economic matters affecting the medical profession.[13]
After the Second World War, amid the rapid improvement of the level of medical research technology, the modernization of diagnosis and treatment means and health facilities and equipment, the aging of the population, the sharp increase of chronic diseases, and the improvement of people's demand for health care and other reasons, medical and health expenses increased significantly. For example, total U.S. health expenditures steadily increased as a share of gross domestic product (GDP), demonstrating the increased importance that society placed on health care relative to other non-health goods and services. Between 1960 and 2013, health spending as a share of GDP increased from 5.0 to 17.4 percent. Over the same period, the average annual growth in nominal national health expenditures was 9.2 percent compared to nominal GDP growth of 6.7 percent.[14]
At the same time, the expenditure on health care in many European countries also increased, accounting for about 4% of GDP in the 1950s and 8% by the end of the 1970s. In terms of growth rate, the proportion of health care expenditure in GNP (gross national product) in many countries increased by 1% in the 1950s, 1.5% in the 1960s, and 2% in the 1970s. This high medical and health expenditure was a heavy economic burden on government, business owners, workers, and families, which required a way to restrain its growth.[15]
In addition, the scale of health service increased, technical equipment became more advanced, and division of labor and specialization saw increases, too. The medical and health service developed into a "healthcare industry" which occupies a considerable amount of capital and labor and occupies an important position in social and economic life. The research on economic problems of the health sector became an important topic of economic research.[16]
Selma Muskin published "Towards the definition of health economics" in 1958 and, four years later, the paper, "Health as an Investment". At that time, health was broadly regarded as rather a consumptive branch of the economy. Muhkin's analysis was the first understanding that health investment had long-term beneficial consequences for the community. Probably, the single most famous and cited contribution to the discipline was Kenneth Arrow's "Uncertainty and the welfare economics of medical care", published in 1963.[12][17]
After the 1960s, research in health economics developed further, and a second academic seminar on health economics was held in the United States in 1962 followed by a third in 1968. In 1968, the World Health Organization held its first international health economics seminar in Moscow. The convening of the three meetings showed that health economics had boarded an academic forum as an independent discipline, which also marked the official formation of health economics.[18]
After the 1970s, the health economy entered a period of rapid development and nursing economics gradually emerged. In 1979, Paul Feldstein, an American health economist, first used the principles of economics to discuss the long-term care market, registered market, and other nursing economy issues, laying the foundation for the emergence of nursing economics.[19]
In 1983, Nursing Economic Magazine was founded in the United States, and its main research content included nursing market development, nursing cost accounting, policies related to nursing services, nursing economic management, etc. The magazine's publication was a mark of the formal formation of nursing economics. In 1993, The University of Iowa Cost Research Center conducted a systematic nursing cost study, simply the NIC System. The specific practice consisted of establishing a special research institution equipped with full-time researchers, sorting out the nursing cost accounting content, and, finally, identifying 433 items in 6 categories. At the same time, the Center adopted computer technology to carry out nursing cost management, including cost assessment, reasonable budget, decision making, etc., which played a crucial role in improving the efficiency of nursing management and alleviating the nursing management crisis.[20]
Healthcare demand
The demand for healthcare is a derived demand from the demand for health. Healthcare is demanded as a means for consumers to achieve a larger stock of "health capital". The demand for health is unlike most other goods because individuals allocate resources in order to both consume and produce health.[citation needed]
The above description gives three roles of persons in health economics. The World Health Report (p.52) states that people take four roles in healthcare:
Contributors
Citizens
Provider
Consumers
Michael Grossman's 1972 model of health production[21] has been extremely influential in this field of study and has several unique elements that make it notable. Grossman's model views each individual as both a producer and a consumer of health. Health is treated as a stock which degrades over time in the absence of "investments" in health, so that health is viewed as a sort of capital. The model acknowledges that health is both a consumption good that yields direct satisfaction and utility, and an investment good, which yields satisfaction to consumers indirectly through fewer sick days. Investment in health is costly as consumers must trade off time and resources devoted to health, such as exercising at a local gym, against other goals. These factors are used to determine the optimal level of health that an individual will demand. The model makes predictions over the effects of changes in prices of healthcare and other goods, labour market outcomes such as employment and wages, and technological changes. These predictions and other predictions from models extending Grossman's 1972 paper form the basis of much of the econometric research conducted by health economists.[citation needed]
In Grossman's model, the optimal level of investment in health occurs where the marginal cost of health capital is equal to the marginal benefit. With the passing of time, health depreciates at some rate . The interest rate faced by the consumer is denoted by . The marginal cost of health capital can be found by adding these variables: . The marginal benefit of health capital is the rate of return from this capital in both market and non-market sectors. In this model, the optimal health stock can be impacted by factors like age, wages and education. As an example, increases with age, so it becomes more and more costly to attain the same level of health capital or health stock as one ages. Age also decreases the marginal benefit of health stock. The optimal health stock will therefore decrease as one ages.[citation needed]
Beyond issues of the fundamental, "real" demand for medical care derived from the desire to have good health (and thus influenced by the production function for health) is the important distinction between the "marginal benefit" of medical care (which is always associated with this "real demand" curve based on derived demand), and a separate "effective demand" curve, which summarizes the amount of medical care demanded at particular market prices. Because most medical care is not purchased from providers directly, but is rather obtained at subsidized prices due to insurance, the out-of-pocket prices faced by consumers are typically much lower than the market price. The consumer sets out of pocket, and so the "effective demand" will have a separate relationship between price and quantity other than the "marginal benefit curve" or real demand relationship will have. This distinction is often described under the rubric of "ex-post moral hazard" (which is again distinct from ex-ante moral hazard, which is found in any type of market with insurance).
Some agencies, including NICE, recommend the use of cost–utility analysis (CUA). This approach measures outcomes in a composite metric of both length and quality of life, the Quality-adjusted life year (QALY).
Healthcare markets
The five health markets typically analyzed are:[citation needed]
Although assumptions of textbook models of economic markets apply reasonably well to healthcare markets, there are important deviations. Many states have created risk pools in which relatively healthy enrollees subsidize the care of the rest. Insurers must cope with adverse selection which occurs when they are unable to fully predict the medical expenses of enrollees; adverse selection can destroy the risk pool. Features of insurance market risk pools, such as group purchases, preferential selection ("cherry-picking"), and preexisting condition exclusions are meant to cope with adverse selection.
Insured patients are naturally less concerned about healthcare costs than they would if they paid the full price of care. The resulting moral hazard drives up costs, as shown by the RAND Health Insurance Experiment. Insurers use several techniques to limit the costs of moral hazard, including imposing copayments on patients and limiting physician incentives to provide costly care. Insurers often compete by their choice of service offerings, cost-sharing requirements, and limitations on physicians.
Consumers in healthcare markets often lack adequate information about what services they need to buy and which providers offer the best value proposition. Health economists have documented a problem with supplier induced demand, whereby providers base treatment recommendations on economic, rather than medical criteria. Researchers have also documented substantial "practice variations", whereby the treatment also on service availability to rein in inducement and practice variations.
Some economists argue that requiring doctors to have a medical license constrains inputs, inhibits innovation, and increases cost to consumers while largely only benefiting the doctors themselves.[22]
Risk-sharing can reduce risk premiums, for example for research and development of new cures and health care equipment.[23]
Health insurance failure
Health insurance failure can be attributed to market failure or government failure.[24]Underinsurance can arise when the cure of disease is very expensive, such as cancer or a wide spread of new diseases such as HIV/AIDS or COVID-19. In such cases either private insurers require a high premium as the risk factor and costs are high or they may not insure the people for a particular case. This leads to a void in the market where a certain section of the population will not be able to afford healthcare. Certain insurance markets, such as those for patients with HIV/AIDS, cancer, or other pre-existing conditions who are searching for new coverage, may be incomplete in the sense that those patients may be unable to afford coverage at any price. In such cases, the government usually intervenes and provides health care for such cases. For example, during the COVID-19 pandemic, no private insurance company predicted (or could have predicted) that such an outbreak would occur; as a result, state intervention became necessary to treat people. Governments can subsidize those who cannot afford insurance or, in certain situations, those low-cost activities and facilities that non-poor citizens can afford on their own. For example; the largest health insurance scheme in the world was launched in India by the name Ayushman Bharat in 2018.[25]
Government might want to intervene in case of market failure in healthcare industry.[26] Several health-care markets tend to have the potential for monopoly control to be exercised. Medical care in markets with few hospitals, patent-protected prescription products, and some health insurance markets is the major reason for higher costs and especially in cases where the providers are private companies.[27] Limitations on physician-owned hospitals are argued to reduce competition between hospitals.[28]
Health spending by country: governmental, voluntary and out-of-pocket
Medical economics
Often used synonymously with health economics, medical economics, according to Culyer,[31] is the branch of economics concerned with the application of economic theory to phenomena and problems associated typically with the second and third health market outlined above: physician and institutional service providers. Typically, however, it pertains to cost–benefit analysis of pharmaceutical products and cost-effectiveness of various medical treatments. Medical economics often uses mathematical models to synthesise data from biostatistics and epidemiology for support of medical decision-making, both for individuals and for wider health policy.[citation needed]
Mental health economics
Mental health economics incorporates a vast array of subject matters, ranging from pharmacoeconomics to labor economics and welfare economics. Mental health can be directly related to economics by the potential of affected individuals to contribute as human capital. In 2009 Currie and Stabile published "Mental Health in Childhood and Human Capital" in which they assessed how common childhood mental health problems may alter the human capital accumulation of affected children.[32] Externalities may include the influence that affected individuals have on surrounding human capital, such as at the workplace or in the home.[33] In turn, the economy also affects the individual, particularly in light of globalization. For example, studies in India, where there is an increasingly high occurrence of western outsourcing, have demonstrated a growing hybrid identity in young professionals who face very different sociocultural expectations at the workplace and in at home.[34]
Mental health economics presents a unique set of challenges to researchers. Individuals with cognitive disabilities may not be able to communicate preferences. These factors represent challenges in terms of placing value on the mental health status of an individual, especially in relation to the individual's potential as human capital. Further, employment statistics are often used in mental health economic studies as a means of evaluating individual productivity; however, these statistics do not capture "presenteeism", when an individual is at work with a lowered productivity level, quantify the loss of non-paid working time, or capture externalities such as having an affected family member. Also, considering the variation in global wage rates or in societal values, statistics used may be contextually, geographically confined, and study results may not be internationally applicable.[33]
Though studies have demonstrated mental healthcare to reduce overall healthcare costs, demonstrate efficacy, and reduce employee absenteeism while improving employee functioning, the availability of comprehensive mental health services is in decline. Petrasek and Rapin (2002) cite the three main reasons for this decline as (1) stigma and privacy concerns, (2) the difficulty of quantifying medical savings and (3) physician incentive to medicate without specialist referral.[35] Evers et al. (2009) have suggested that improvements could be made by promoting more active dissemination of mental health economic analysis, building partnerships through policy-makers and researchers, and employing greater use of knowledge brokers.[33]
Generally, economists assume that individuals act rationally with the aim of maximizing their lifetime utility, while all are subject to the fact that they cannot buy more than their resources allow. However, this model gets complex as there exists the uncertainty over individuals' lifetime. As such, the issue is split into two parts: 1. How does health produce utility and 2. What affects health (e.g., medical care and life-style choices).[37]
Probably the most fundamental thing in consumer demand theory is that the good increases an individual's utility. Health is not really a good in the traditional sense, but health in itself produces happiness. We can think of health as a durable good, much like for instance a car, a house or an education. Every person comes into the world with some inherent "stock" of health, and a healthy baby has a fairly high stock of health. Basically, every decision an individual take during their lifetime will affect their stock of health.[37]
Let X be a bundle of other goods, and H a stock of health. With these variables the formula for an individual's utility is: Utility = U(X, H). For simplicity, the stock of health produces utility, but technically, is the flow of services created by the stock of health that produces utility. As the traditional fashion for goods, "more is better", in other words an increase in health leads to an increase in utility. From this assumption, X grows with health, for instance it is more enjoyable to visit the zoo when not experiencing a headache.[37]
Like other durable goods, the stock of health wears out over time, much like other durable goods. This process can be called aging. When the stock of health has dropped low enough, a person will lose their ability to function. In economic terminology it can be said that the stock of health depreciates. Since life expectancy has risen a lot during this century, it implies that e.g., the depreciation rate has decreased during this time. Public healthcare efforts and individual medical care are in place to restore the stock of health or to decrease the depreciation rate on the stock of health. A plot graph of an individual's stock of health throughout their lifetime would be steadily increasing in the beginning during their childhood, and after that gradually decline because of aging, meanwhile having sudden drops created by random events, such as injury or illness.[37]
There are many other things than "random" health care events, which individuals consume or do during their lives that affect the speed of aging and the severity and frequency of the drops. Lifestyle choices can deeply improve or worsen health of an individual. The variable X, the bundle of goods and services, can undertake numerous characteristics, some add value while others noticeably decrease the stock of health. Outstanding among such lifestyle choices are the decision to consume alcohol, smoke tobacco, use drugs, composition of diet, amount of exercise and so on. Not only can X and H work as substitutes for one another in producing utility, but X can also affect H in a production sense as well. X can then be split into different categories depending on which effect it has on H, for instance "good" types (e.g., moderate exercise), "bad" types (e.g., food with high cholesterol) and "neutral" types (e.g., concerts and books). Neutral goods do not have an apparent effect on individuals' health.[37]
Microeconomics is a branch of economics that studies the behavior of individuals and firms in making decisions regarding the allocation of scarce resources and the interactions among these individuals and firms. Microeconomics focuses on the study of individual markets, sectors, or industries as opposed to the economy as a whole, which is studied in macroeconomics.
In economics, insurance, and risk management, adverse selection is a market situation where asymmetric information results in a party taking advantage of undisclosed information to benefit more from a contract or trade.
The healthcare industry is an aggregation and integration of sectors within the economic system that provides goods and services to treat patients with curative, preventive, rehabilitative, and palliative care. It encompasses the creation and commercialization of products and services conducive to the preservation and restoration of well-being. The contemporary healthcare sector comprises three fundamental facets, namely services, products, and finance. It can be further subdivided into numerous sectors and categories and relies on interdisciplinary teams of highly skilled professionals and paraprofessionals to address the healthcare requirements of both individuals and communities.
Health insurance or medical insurance is a type of insurance that covers the whole or a part of the risk of a person incurring medical expenses. As with other types of insurance, risk is shared among many individuals. By estimating the overall risk of health risk and health system expenses over the risk pool, an insurer can develop a routine finance structure, such as a monthly premium or payroll tax, to provide the money to pay for the health care benefits specified in the insurance agreement. The benefit is administered by a central organization, such as a government agency, private business, or not-for-profit entity.
Consumption is the act of using resources to satisfy current needs and wants. It is seen in contrast to investing, which is spending for acquisition of future income. Consumption is a major concept in economics and is also studied in many other social sciences.
The term managed care or managed healthcare is used in the United States to describe a group of activities intended to reduce the cost of providing health care and providing American health insurance while improving the quality of that care. It has become the predominant system of delivering and receiving American health care since its implementation in the early 1980s, and has been largely unaffected by the Affordable Care Act of 2010.
...intended to reduce unnecessary health care costs through a variety of mechanisms, including: economic incentives for physicians and patients to select less costly forms of care; programs for reviewing the medical necessity of specific services; increased beneficiary cost sharing; controls on inpatient admissions and lengths of stay; the establishment of cost-sharing incentives for outpatient surgery; selective contracting with health care providers; and the intensive management of high-cost health care cases. The programs may be provided in a variety of settings, such as Health Maintenance Organizations and Preferred Provider Organizations.
Government spending or expenditure includes all government consumption, investment, and transfer payments. In national income accounting, the acquisition by governments of goods and services for current use, to directly satisfy the individual or collective needs of the community, is classed as government final consumption expenditure. Government acquisition of goods and services intended to create future benefits, such as infrastructure investment or research spending, is classed as government investment. These two types of government spending, on final consumption and on gross capital formation, together constitute one of the major components of gross domestic product.
Health care prices in the United States of America describe market and non-market factors that determine pricing, along with possible causes as to why prices are higher than in other countries.
Consumer-driven healthcare (CDHC), or consumer-driven health plans (CDHP) refers to a type of health insurance plan that allows employers or employees to utilize pretax money to help pay for medical expenses not covered by their health plan. These plans are linked to health savings accounts (HSAs), health reimbursement accounts (HRAs), or similar medical payment accounts. Users keep any unused balance or "rollover" at the end of the year to increase future balances or to invest for future expenses. They are a high-deductible health plan which has cheaper premiums but higher out of pocket expenses, and as such are seen as a cost effective means for companies to provide health care for their employees.
In the United States, a high-deductible health plan (HDHP) is a health insurance plan with lower premiums and higher deductibles than a traditional health plan. It is intended to incentivize consumer-driven healthcare. Being covered by an HDHP is also a requirement for having a health savings account. Some HDHP plans also offer additional "wellness" benefits, provided before a deductible is paid. High-deductible health plans are a form of catastrophic coverage, intended to cover for catastrophic illnesses. Adoption rates of HDHPs have been growing since their inception in 2004, not only with increasing employer options, but also increasing government options. As of 2016, HDHPs represented 29% of the total covered workers in the United States; however, the impact of such benefit design is not widely understood.
In the United States, health insurance helps pay for medical expenses through privately purchased insurance, social insurance, or a social welfare program funded by the government. Synonyms for this usage include "health coverage", "health care coverage", and "health benefits". In a more technical sense, the term "health insurance" is used to describe any form of insurance providing protection against the costs of medical services. This usage includes both private insurance programs and social insurance programs such as Medicare, which pools resources and spreads the financial risk associated with major medical expenses across the entire population to protect everyone, as well as social welfare programs like Medicaid and the Children's Health Insurance Program, which both provide assistance to people who cannot afford health coverage.
In economics, supplier induced demand (SID) may occur when asymmetry of information exists between supplier and consumer. The supplier can use superior information to encourage an individual to demand a greater quantity of the good or service they supply than the Pareto efficient level, should asymmetric information not exist. The result of this is a welfare loss.
Cost-shifting is an economic situation where one individual, group, or government underpays for a service, resulting in another individual, group, or government overpaying for a service. It can occur when one group pays a smaller share of costs than before, resulting in another group paying a larger share of costs than before. Some commentators on health policy in the United States believe the former currently happens in Medicare and Medicaid as they underpay for services resulting in private insurers overpaying. Although the term cost shift is used in the field of healthcare these days and there are many studies about it, other fields have more or less used it. For example, its origins go back to the environmental economy where cost-shifting referred to the practice where corporations pass the harmful consequences and negative externalities of economic production to third parties and communities whether those that are part of the production circuit or are in some way beneficiaries or those that are outside this circle, K.W. Kapp, is one who coined the concept. This concept is also used in the American legal system, especially since the cost of electronic discovery has increased dramatically due to a large amount of raw information and the urgent need to extract relevant data, its processing, and analysis. In the past, each of the plaintiffs and defendants had to bear the cost, but later many of those who prepared the summons demanded the transfer of the cost because they thought they would have to pay for something they did not do. In this regard, some courts have agreed to shift part of the costs to the complainant.
There were a number of different health care reforms proposed during the Obama administration. Key reforms address cost and coverage and include obesity, prevention and treatment of chronic conditions, defensive medicine or tort reform, incentives that reward more care instead of better care, redundant payment systems, tax policy, rationing, a shortage of doctors and nurses, intervention vs. hospice, fraud, and use of imaging technology, among others.
Healthcare in the United States is largely provided by private sector healthcare facilities, and paid for by a combination of public programs, private insurance, and out-of-pocket payments. The U.S. is the only developed country without a system of universal healthcare, and a significant proportion of its population lacks health insurance. The United States spends more on healthcare than any other country, both in absolute terms and as a percentage of GDP; however, this expenditure does not necessarily translate into better overall health outcomes compared to other developed nations. Coverage varies widely across the population, with certain groups, such as the elderly and low-income individuals, receiving more comprehensive care through government programs such as Medicaid and Medicare.

Chan School of Public Health in Boston, and Harvard Faculty of Arts and Sciences in Cambridge.
Health care finance in the United States discusses how Americans obtain and pay for their healthcare, and why U.S. healthcare costs are the highest in the world based on various measures.
This glossary of economics is a list of definitions containing terms and concepts used in economics, its sub-disciplines, and related fields.
Health care efficiency is a comparison of delivery system outputs, such as physician visits, relative value units, or health outcomes, with inputs like cost, time, or material. Efficiency can be reported then as a ratio of outputs to inputs or a comparison to optimal productivity using stochastic frontier analysis or data envelopment analysis. An alternative approach is to look at latency times and delay times between a care order and completion of work, and stated accomplishment in relation to estimated effort.
The Grossman model of health demand is a model for studying the demand for health and medical care outlined by Michael Grossman in a monograph in 1972 entitled: The demand for health: A theoretical and empirical investigation. The model based demand for medical care on the interaction between a demand function for health and a production function for health. Andrew Jones, Nigel Rice, and Paul Contoyannis call the model the "founding father of demand for health models".
