Lecture 10 - Health Care and Education
Health Care and Education
Fundamental problems facing health care and education systems arise from information asymmetry. This occurs when one party has more or better information than the other, leading to potential exploitation. Externalities, which are costs or benefits that affect a third party who did not choose to incur that cost or benefit, also pose a challenge. Additionally, the difficulty in measuring output in both sectors complicates assessment and improvement efforts.
Reasons for government intervention encompass addressing market failures, ensuring equity by providing access to essential services for all, and promoting positive externalities that benefit society as a whole.

The Health Care Problem
Spending on health care as a percentage of GDP varies significantly across countries due to differing priorities, healthcare systems, and levels of economic development. Factors such as cultural attitudes, political ideologies, and historical trajectories also influence healthcare spending patterns.
Supply Creates Its Own Demand
In health care, the concept that supply creates its own demand is widely debated due to:
The principal-agent nature of healthcare, wherein doctors (agents) influence the healthcare decisions of patients (principals). This dynamic can lead to over-prescription, unnecessary procedures, and increased healthcare costs.
Consumer expectations that increased availability of healthcare services will lead to better health outcomes, driving demand for more services regardless of their actual effectiveness.
Spending on health care (% of GDP) vs. Life Expectancy (years) varies across countries, indicating that higher spending does not always correlate with longer life expectancy. Factors such as lifestyle, environmental conditions, and access to preventive care also play significant roles in determining health outcomes.
What Is Health Care?
Determining the output of health care is challenging due to the multifaceted nature of health and well-being. Health encompasses physical, mental, and social aspects, making it difficult to define and measure comprehensively.
Should output be measured as 'healthy people,' 'productive people,' or something else? Each metric has its limitations and implications. Measuring health solely in terms of physical well-being may overlook mental and social dimensions, while focusing on productivity may neglect the intrinsic value of health.
How can we measure the output of care, considering factors such as quality of life, disease prevention, and patient satisfaction? Assessing the value of healthcare interventions requires considering their impact on various aspects of patients' lives, including physical function, emotional well-being, and social relationships.
Is health due to health care, genetics, or personal care? Disentangling these factors is essential for assessing the effectiveness of healthcare interventions. Genetic predispositions, lifestyle choices, and environmental factors all contribute to an individual's health status, making it challenging to isolate the specific impact of healthcare interventions.
To measure health care and determine efficient allocation, we need to address:
What is the value of a hip replacement in terms of improved mobility, reduced pain, and enhanced quality of life? Quantifying these benefits is essential for justifying the cost of the procedure and allocating resources effectively.
What is the value of 2 years of extra life, taking into account the individual's age, health status, and potential contributions to society? This involves complex ethical and economic considerations, as different individuals may place different values on additional years of life.
What is the value of better eyesight, considering its impact on productivity, social interaction, and overall well-being? Vision impairment can significantly impact an individual's ability to work, socialize, and perform daily tasks, highlighting the importance of vision care.
There is clearly no correct answer to such questions, as values are subjective and depend on individual preferences and societal norms. Ethical frameworks and societal values play a crucial role in determining how we prioritize and allocate healthcare resources.
Efficiency in Health Care
The notion of efficiency in health care is controversial, as it involves making difficult trade-offs between competing priorities. Efficiency implies maximizing health outcomes with limited resources, which may require making difficult choices about which treatments and interventions to prioritize.
However:
An efficient health service doesn't give all patients the highest possible care, but rather allocates resources in a way that maximizes overall health outcomes. This may involve prioritizing preventive care over expensive treatments or allocating resources to interventions with the greatest potential impact.
Money spent treating one patient is not spent treating another or in the education system, highlighting the opportunity cost of healthcare spending. Every healthcare decision involves trade-offs, and resources spent on one area could be used for other important priorities.
This opportunity cost must be recognized by doctors and surgeons deciding where to use resources, promoting responsible and evidence-based decision-making. Healthcare providers should be aware of the broader implications of their decisions and strive to make choices that benefit society as a whole.
Efficiency in the Health Service
How to measure opportunity cost?
QALY (quality-adjusted life years) is one way to measure the benefits of treatment, combining both the quantity and quality of life gained. QALYs provide a standardized metric for comparing the value of different healthcare interventions.
NICE (National Institute for Health and Care Excellence) determines what is efficient in the UK, providing guidance on which treatments and interventions represent good value for money. NICE's recommendations influence healthcare decision-making and resource allocation in the UK.
Examples of QALYs
Description and QALY values:
No problems: 1.000
No problems walking, self-care; some problems with usual activities; some pain/discomfort; not anxious/depressed: 0.760
No problems walking; some problems washing/dressing; unable to perform usual activities; moderate pain/discomfort; extremely anxious/depressed: 0.222
Measure for cost-effectiveness: Cost/QALY, which helps to compare the relative value of different healthcare interventions. Interventions with lower cost/QALY ratios are generally considered more cost-effective.
Equity in Health Care?
Different measures of equity:
Minimum standard: any individual should receive a minimum standard of treatment, regardless of their ability to pay or other characteristics. This ensures that everyone has access to basic healthcare services, regardless of their socioeconomic status.
Equality of expenditure: each patient receives the same expenditure, which may not be equitable if patients have different healthcare needs. Some patients may require more intensive or specialized care, necessitating higher levels of expenditure.
Equal treatment for equal need: each patient receives the same treatment for the same condition, promoting fairness and consistency. This ensures that patients with similar health conditions receive comparable care, regardless of their background or circumstances.
Equal access or equality of cost: each patient has the same cost to receive treatment, reducing financial barriers to healthcare access. This may involve subsidies, insurance programs, or other mechanisms to ensure that healthcare costs do not disproportionately burden low-income individuals.
Equality of output: each patient has the same health, which is an ideal but often unattainable goal due to individual differences and social determinants of health. Individual health outcomes are influenced by a complex interplay of factors, including genetics, lifestyle, and environmental conditions.
Equity or Efficiency?
What does the social welfare function look like regarding health care, and how does it balance equity and efficiency considerations? Social welfare functions reflect society's preferences for different outcomes, and healthcare policies should aim to maximize social welfare while balancing competing goals.
Should smokers receive cancer treatment, raising questions about personal responsibility and healthcare resource allocation? This raises ethical dilemmas about whether individuals should be held responsible for health conditions resulting from their lifestyle choices.
Should basic maternity services be free, reflecting the societal value placed on childbirth and family well-being? Many societies view maternity care as a fundamental right and provide it free of charge to ensure healthy pregnancies and childbirth.
Should a rich person not be able to purchase better health care, addressing concerns about inequality and access to quality care? This raises questions about the role of private healthcare and whether it should be allowed to create disparities in access to care.
Some prioritize efficiency over equity, arguing that maximizing overall health outcomes is more important than ensuring equal access to care. This perspective emphasizes the importance of allocating resources where they will have the greatest impact on population health.
But, What About Efficiency?
Check possible causes of market failure:
Is health care a public good? No, as it is typically rivalrous and excludable. Public goods are non-rivalrous (one person's consumption does not diminish its availability to others) and non-excludable (it is difficult to prevent people from consuming the good).
Is there imperfect information? Yes, lots, due to the complexity of medical knowledge and the information asymmetry between providers and patients. Patients often lack the expertise to make informed decisions about their healthcare, leading to potential exploitation by providers.
Is there imperfect competition? Yes, due to barriers to entry, regulatory constraints, and the concentration of healthcare providers in certain areas. These factors can limit consumer choice and lead to higher prices and lower quality of care.
Do externalities exist? Yes, as individual health decisions can impact public health and the spread of infectious diseases. Vaccination, for example, generates positive externalities by reducing the risk of disease transmission to others.
Are there likely to be incomplete markets? Yes, particularly in the market for long-term care insurance and preventative healthcare services. These markets may be underdeveloped due to uncertainty, adverse selection, and moral hazard.
Clearly, there are lots of reasons for market failure in healthcare, justifying government intervention to correct these failures. Government intervention can take various forms, including regulation, subsidies, and direct provision of healthcare services.
Imperfect Information
A patient cannot predict if and when they will be ill, so insurance is fundamental for managing healthcare costs and risks. Insurance allows individuals to pool their risks and share the costs of healthcare.
This raises problems:
Patients may not know if they are ill or may think they are ill when they are not, leading to over- or under-utilization of healthcare services. This can result in unnecessary healthcare costs and inefficient resource allocation.
Patients will not understand possible treatments, making it difficult to make informed decisions about their care. Patients may rely heavily on their doctors' recommendations, even if they are not fully informed about the risks and benefits of different treatment options.
Health care relies on a principal-agent relationship (patient is the principal, doctor is the agent), which can create conflicts of interest and ethical dilemmas. Doctors may have incentives to recommend treatments that are not in the best interests of their patients, such as those that generate higher profits.
Imperfect Competition and Externalities
There are local monopolies in healthcare, particularly in rural areas with limited provider choices. This can result in higher prices and lower quality of care for patients in these areas.
There are increasing returns to scale in providing health care, suggesting natural monopolies and the potential for cost savings through consolidation. Larger healthcare systems may be able to achieve economies of scale and provide services more efficiently.
An ill person is unlikely to 'shop around' for the best deal, reducing competitive pressures and potentially leading to higher prices and lower quality. Patients are often in a vulnerable state when seeking healthcare, making it difficult for them to compare prices and quality across different providers.
There are positive externalities to good health, such as increased productivity, reduced healthcare costs, and improved social well-being. A healthy population is more productive and contributes more to the economy.
Incomplete Markets and Insurance
Because people do not know when they will be ill, an insurance system is needed to pool risks and provide financial protection. Insurance helps individuals manage the financial risks associated with unexpected healthcare costs.
A private insurance system will encounter many problems:
Moral hazard: insured people take more risk (smoking, getting pregnant, etc.), increasing healthcare costs. Moral hazard occurs when individuals change their behavior after obtaining insurance, leading to increased risk-taking and higher costs.
Adverse selection: healthy people will be asked to pay relatively unfair (high) premiums and so may choose not to insure. Seen in the US with the high proportion of uninsured 18-25 year olds. Adverse selection occurs when individuals with higher risks are more likely to purchase insurance, leading to a pool of insured individuals with higher average healthcare costs.
Could the Government Do Any Better?
Solving market failure is difficult, and the problems of incomplete information and imperfect competition are not easily solved. Government intervention can help to address these problems, but it may also create new challenges.
The government can solve the problem of incomplete markets and improve equity through universal healthcare coverage and subsidies. Universal healthcare coverage ensures that everyone has access to healthcare, regardless of their ability to pay. Subsidies can help to make healthcare more affordable for low-income individuals.
This suggests government production and possibly government finance of healthcare services. Government production of healthcare services can help to ensure that everyone has access to quality care, while government finance can help to make healthcare more affordable.
Education: The Questions We Shall Raise
What is the product/good we call education, and how does it contribute to individual and societal well-being? Education encompasses knowledge, skills, values, and attitudes that contribute to personal growth and societal development.
Does a private market provide an efficient and equitable allocation of education, considering factors such as access, affordability, and quality? Private markets may fail to provide equitable access to education due to disparities in income, location, and other factors.
Reasons for government intervention include addressing market failures, promoting equity, and ensuring a well-educated populace. Government intervention can help to ensure that everyone has access to quality education, regardless of their socioeconomic status.
What Is Education?
As with health care, it is hard to measure the output of education due to the complexity of knowledge, skills, and personal development. Education involves a wide range of outcomes that are difficult to quantify, such as critical thinking, problem-solving, and creativity.
One commonly used measure of output is exam results. But:
Are exam results due to education or innate intelligence, good parenting, etc.? Disentangling these factors is essential for assessing the effectiveness of educational interventions. Exam results may be influenced by factors outside of the classroom, such as family support and socioeconomic status.
Should we recognize consumption benefits: students enjoy being at school or university, enhancing their quality of life and social well-being? Education can provide intrinsic value and contribute to personal fulfillment.
Should we recognize investment benefits: educated people receive high job satisfaction and higher salaries, contributing to economic growth and prosperity? Education can increase individuals' earning potential and contribute to economic growth.
Why Is There Positive Returns to Education?
Women with a university degree earn on average 28% more than non-graduate women, highlighting the economic value of higher education.
Human Capital Theory (Gary Becker): Education is an investment in human capital that increases productivity and earnings. Human capital refers to the knowledge, skills, and abilities that individuals acquire through education and training.
Signaling/Screening (Spence): Education serves as a signal of ability and motivation to employers, leading to better job opportunities and higher wages.
(\%28)
Pareto Efficiency in Education?
Measuring the costs of providing education is relatively simple (buildings, books, teacher salaries, etc.). The costs of education are generally easier to quantify than the benefits.
Given that we struggle to determine the output of education, measuring efficiency is hard, requiring careful consideration of both costs and benefits. Measuring efficiency requires a comprehensive assessment of both the inputs and outputs of education.
The benefits are much more difficult to measure. How should we measure the benefits society receives from your education, such as innovation, civic engagement, and social cohesion? Education can generate a wide range of social benefits that are difficult to quantify.
Equity in Education?
It is almost universally believed that equity is important in education provision: equal opportunities for all students to succeed. Equity ensures that all students have the opportunity to reach their full potential, regardless of their background or circumstances.
As with health care, there are different definitions of equity:
Equality of consumption (Rawlsian): Providing equal resources and opportunities to all students, regardless of their background or circumstances. This aims to level the playing field and ensure that all students have access to the resources they need to succeed.
Equality of opportunity or access (Utilitarian): Ensuring that all students have access to quality education, regardless of their socioeconomic status or geographic location. This focuses on providing equal access to educational opportunities, but may not address underlying disparities in resources and support.
Minimum standard: Guaranteeing a basic level of education for all students, ensuring they acquire essential skills and knowledge. This ensures that all students have the foundational skills and knowledge they need to participate in society and the economy.
Financing Higher Education
Over the last 20 years, successive UK governments have promoted an increase in higher education, aiming to boost skills and economic competitiveness. Higher education is seen as a key driver of economic growth and social mobility.
Is this efficient?
Some claim we need a higher-skilled workforce to meet the demands of a knowledge-based economy. A highly skilled workforce is essential for innovation and competitiveness in the global economy.
Others claim that students might as well enjoy themselves for a few years, contributing to personal growth and cultural enrichment. Education can provide intrinsic value and contribute to personal fulfillment.
Others think that it is inefficient costly signalling, with students overinvesting in education to signal their ability to employers. Costly signaling refers to the idea that individuals may invest in education to signal their ability to employers, even if the education does not directly increase their productivity.
We Need to Check the Possible Causes of Market Failure
Is education a public good? No, as it is typically rivalrous and excludable. Public goods are non-rivalrous (one person's consumption does not diminish its availability to others) and non-excludable (it is difficult to prevent people from consuming the good).
Does imperfect information exist? Yes, and lots, due to the complexity of educational choices and the uncertainty about future returns. Students and their families may lack information about the quality of different educational programs and the potential returns on investment.
Does imperfect competition exist? Yes, due to school choice limitations and the concentration of resources in certain areas. School choice may be limited by geography, income, and other factors.
Are there incomplete markets? Yes, particularly in the market for student loans and financing higher education. Access to student loans may be limited by creditworthiness and other factors.
Are there externalities? Yes, such as increased civic engagement, reduced crime rates, and improved public health. Education can generate positive externalities that benefit society as a whole.
Why does a market-based system of education fail? Due to these market failures, government intervention is often necessary to ensure efficient and equitable provision of education. Government intervention can take various forms, including regulation, subsidies, and direct provision of education services.
How to Think of the Education Choice?
We need to look at the benefits and costs of education over the lifetime (e.g., go to University or not)? The decision to pursue higher education involves weighing the costs and benefits over the long term.
Going to Uni improves leisure time, providing opportunities for personal growth and social interaction. University provides opportunities for students to develop their interests, build relationships, and expand their horizons.
Wages are initially higher if you do not go, but eventually are higher if you do go, reflecting the long-term economic benefits of higher education. Individuals who pursue higher education typically earn more over their lifetimes than those who do not.
Going to Uni costs money (tuition fees, etc.), which can create financial barriers for some students. The cost of higher education can be a significant barrier for some students, particularly those from low-income backgrounds.
Imperfect Information
The choice of whether to go to uni is a complicated one, involving uncertainty about future career prospects and personal development. Students may be unsure about their career goals and the potential benefits of different educational paths.
The choice is no easier for younger children: what school to go to, what subjects to study, how hard to study, requiring guidance from parents and educators. Young children rely on their parents and educators to guide them in making educational decisions.
Is a six-year-old child able to make an informed decision about his education needs? Are his parents? This highlights the need for government intervention to ensure children receive a quality education. Government intervention can help to ensure that all children have access to a quality education, regardless of their background or circumstances.
We obtain principal-agent relationships where one person (parent, teacher, government) acts on behalf of the child, potentially leading to conflicts of interest and ethical dilemmas. Principal-agent relationships can create conflicts of interest, as the agent may not always act in the best interests of the principal.
We also need people to have an understanding of the returns to education, which can be difficult to assess due to uncertainty and changing labor market conditions. The returns to education can vary depending on the field of study, the state of the economy, and other factors.
For perfect information, we need to know the prices and quality of the good being bought. Is this possible in education? The complexity of education makes it difficult to assess its true value. It is difficult to compare the quality of different educational programs and institutions.
Education is something that you do not purchase many times, reducing opportunities for learning and improvement. Individuals typically only have one opportunity to pursue a particular level of education.
Other Market Failures
Imperfect competition
There are increasing returns to scale in education, suggesting the potential for efficiency gains through larger schools and universities. Larger schools and universities may be able to offer a wider range of programs and services.
The price and quality of education are not transparent to allow competition, making it difficult for consumers to make informed choices. It is difficult to compare the prices and quality of different educational programs and institutions.
Incomplete markets
The opportunity to borrow money to finance an education may not exist, particularly for students from low-income backgrounds. Access to student loans may be limited by creditworthiness and other factors.
Government Finance Is the Norm
Public spending on non-tertiary education (%) varies across countries, reflecting different priorities and approaches to education finance. Government funding plays a significant role in financing education in most countries.
