Health Economics: Structured Study Notes
Introduction
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. It applies economic theories and quantitative methods to analyze health systems, health behaviors, and health interventions, aiming to optimize resource allocation and improve population health outcomes. Health economics is critical for policymakers, healthcare providers, and researchers, as it informs decisions about funding, access, and the design of healthcare services.
Main Concepts
1. Demand and Supply in Healthcare
- Demand: Driven by factors such as population demographics, prevalence of diseases, income, insurance coverage, and health awareness. Unlike typical markets, demand for healthcare is often unpredictable and urgent.
- Supply: Includes healthcare professionals, facilities, pharmaceuticals, and technologies. Supply is affected by regulatory policies, training, and investment in infrastructure.
- Market Failure: Healthcare markets often experience failures due to information asymmetry, externalities, and moral hazard.
2. Cost Analysis
- Direct Costs: Medical expenses such as hospital stays, medications, and procedures.
- Indirect Costs: Loss of productivity due to illness, disability, or premature death.
- Intangible Costs: Pain, suffering, and reduced quality of life.
- Cost-Effectiveness Analysis (CEA): Compares the relative costs and outcomes of different interventions.
- Cost-Benefit Analysis (CBA): Assigns monetary values to health outcomes to evaluate the net benefit of interventions.
3. Health Financing
- Public Financing: Funded through taxation, social health insurance, or government budgets.
- Private Financing: Includes out-of-pocket payments, private insurance, and employer-sponsored plans.
- Universal Health Coverage (UHC): Aims to provide access to essential health services without financial hardship.
4. Equity and Access
- Equity: Fair distribution of healthcare resources, considering socioeconomic status, geography, and ethnicity.
- Access Barriers: Include financial constraints, lack of transportation, and cultural or language differences.
- Social Determinants of Health: Factors such as education, income, and environment that influence health outcomes.
5. Health Outcomes Measurement
- Quality-Adjusted Life Years (QALYs): Combines quantity and quality of life to assess the value of medical interventions.
- Disability-Adjusted Life Years (DALYs): Measures the burden of disease by accounting for years lost due to illness or disability.
- Patient-Reported Outcomes (PROs): Direct feedback from patients about their health status and treatment satisfaction.
6. Behavioral Economics in Health
- Nudges: Subtle policy shifts that encourage healthier choices without restricting options.
- Incentives: Financial or non-financial rewards for healthy behaviors, such as quitting smoking or regular exercise.
- Risk Preferences: Individuals’ willingness to take risks affects health-related decisions, such as insurance uptake.
Emerging Technologies in Health Economics
1. Artificial Intelligence (AI) and Machine Learning
- Predictive Analytics: AI models forecast disease outbreaks, patient risk, and resource needs.
- Personalized Medicine: Algorithms tailor treatments to individual genetic profiles, improving effectiveness and reducing costs.
- Operational Efficiency: Automation streamlines administrative tasks, reducing overhead and errors.
2. Telemedicine and Digital Health
- Remote Consultations: Expand access to care, especially in underserved areas.
- Mobile Health Apps: Promote self-management of chronic diseases and monitor health behaviors.
- Electronic Health Records (EHR): Facilitate data sharing, improving coordination and reducing duplication.
3. Blockchain Technology
- Secure Data Sharing: Enhances privacy and interoperability of health information.
- Smart Contracts: Automate insurance claims and payments, reducing fraud and administrative costs.
4. Big Data Analytics
- Population Health Management: Identifies trends, allocates resources, and evaluates interventions.
- Real-Time Surveillance: Tracks infectious diseases and monitors public health emergencies.
Environmental Implications
Health economics increasingly recognizes the interplay between environmental factors and health outcomes. Environmental degradation, such as plastic pollution, impacts public health by contaminating water sources, food chains, and living environments. For example, microplastics have been detected in the deepest parts of the ocean, raising concerns about their entry into the human food chain and potential health effects.
- Healthcare Waste: Hospitals and clinics generate significant amounts of plastic waste, including syringes, gloves, and packaging. Improper disposal contributes to environmental pollution.
- Resource Allocation: Health economics encourages investment in sustainable healthcare practices, such as reducing single-use plastics and adopting green technologies.
- Policy Responses: Economic evaluations inform regulations on pollution control, waste management, and incentives for environmentally friendly healthcare products.
A recent study published in Science Advances (2020) found microplastics in the Mariana Trench, highlighting the global scale of plastic pollution and its potential health risks (Peng et al., 2020). This underscores the need for integrated policies that address both health and environmental sustainability.
Memory Trick

Remembering “CASH BE” helps recall the core domains of health economics: Costs, Access, Supply, Health outcomes, Behavioral economics, and Emerging technologies.
Conclusion
Health Economics provides a framework for analyzing the allocation of resources in healthcare, measuring the impact of interventions, and guiding policy decisions. Its scope spans demand and supply dynamics, cost analysis, health financing, equity, and the integration of new technologies. Environmental considerations, such as plastic pollution, increasingly shape health economic evaluations and policy recommendations. By understanding these concepts, young researchers can contribute to more efficient, equitable, and sustainable health systems.
