Health Economics: Study Notes
What is Health Economics?
Health Economics is a branch of economics that studies how health care resources are allocated, used, and financed. It examines the efficiency, effectiveness, value, and behavior in the production and consumption of health and health care.
History of Health Economics
-
Early Beginnings (1900s):
Health Economics emerged as a distinct field in the mid-20th century. Before this, health care was mostly managed by governments or charities, with little focus on costs or outcomes. -
Development (1960s-1980s):
The field grew rapidly with the introduction of national health insurance programs (like Medicare in the US, NHS in the UK). Economists began analyzing how health care spending impacted national budgets and individual well-being. -
Key Milestones:
- 1963: Kenneth Arrow’s paper “Uncertainty and the Welfare Economics of Medical Care” explained why health care markets are different from other markets.
- 1970s: Introduction of cost-effectiveness analysis and health technology assessment.
- 1980s: Expansion into global health, focusing on developing countries and epidemics.
Key Experiments in Health Economics
-
RAND Health Insurance Experiment (1974-1982):
The US government ran a large study to see how people’s health and spending changed when they paid more or less for health care. Results showed that higher costs led to less use of health services, but only small changes in health outcomes for most people. -
Oregon Health Insurance Experiment (2008):
Researchers studied people who gained Medicaid coverage through a lottery. Those with coverage used more health services and felt better about their health, but there was little change in some health measures. -
Behavioral Economics in Health:
Experiments have shown that people often make irrational choices about health (e.g., skipping vaccines or checkups), so policies now use “nudges” to encourage better decisions.
Modern Applications
-
Drug Pricing:
Health economists study how new drugs are priced and how insurance companies decide what to cover. -
AI and Machine Learning:
Artificial intelligence is now used to discover new drugs and materials, analyze health data, and predict outbreaks. AI can help find patterns in huge datasets that humans might miss. -
Telemedicine:
Economists examine how virtual doctor visits affect costs and access, especially in rural or underserved areas. -
Global Health:
Health economics helps allocate resources to fight diseases like malaria, HIV/AIDS, and COVID-19. -
Public Policy:
Governments use health economics to decide how much to spend on hospitals, vaccines, and prevention programs.
Case Studies
1. COVID-19 Vaccine Distribution
Economists helped design systems to distribute vaccines efficiently, prioritizing high-risk groups and balancing costs with benefits.
2. AI in Drug Discovery
A 2023 study published in Nature showed how AI models can predict the effectiveness of new drug compounds, speeding up the process and reducing costs.

3. Sugar Tax Policies
Countries like Mexico and the UK have used taxes on sugary drinks to reduce consumption and improve public health. Economists measure the impact on health outcomes and government revenue.
Practical Experiment
Experiment: How Do Costs Affect Health Choices?
Objective:
To understand how price changes influence students’ choices about health products.
Materials:
- Play money
- Healthy snacks (fruit, granola bars)
- Less healthy snacks (chips, candy)
- Price tags
Procedure:
- Assign each student a budget using play money.
- Set up a “store” with healthy and unhealthy snacks at different prices.
- Ask students to choose snacks within their budget.
- Change the prices (make healthy snacks cheaper, unhealthy snacks more expensive).
- Observe and record changes in choices.
Discussion:
How did price changes affect decisions? What does this say about real-world health economics?
How Health Economics Is Taught in Schools
-
Middle School:
Health Economics is introduced through social studies, health, and economics classes. Students learn about health care systems, costs, and basic budgeting. -
High School:
More detailed lessons cover insurance, public health policies, and careers in health economics. Case studies and experiments are common. -
Practical Activities:
- Budgeting exercises
- Debates on health care policies
- Role-playing as policymakers or patients
-
Use of Technology:
Interactive simulations and online resources help students explore health economics concepts.
Recent Research & News
-
AI Revolutionizes Drug Discovery:
According to a 2023 Nature article, AI technologies now help identify promising drugs faster and more cheaply than traditional methods. This is changing how pharmaceutical companies and health systems invest in new treatments. -
COVID-19 and Health Economics:
The pandemic highlighted the importance of health economics in resource allocation, vaccine distribution, and evaluating the cost-effectiveness of interventions.
Summary
Health Economics is the study of how health care resources are used and distributed. It has evolved from basic budgeting to advanced analyses using artificial intelligence. Key experiments have shown how costs affect health choices, and modern applications include drug pricing, telemedicine, and global health policy. Case studies such as COVID-19 vaccine distribution and AI in drug discovery show the real-world impact of health economics. In schools, students learn through practical activities, simulations, and debates. Recent research highlights the growing role of AI in health economics, making the field more important than ever for understanding and improving health systems.
