“The curious task of economics is to demonstrate to men how little they really know about what they imagine they can design.”
~F. A. Hayek The Fatal Conceit

Why study health economics?
![Page 4: Health Economics Taggert J. Brooks Spring 2013. “The curious task of economics is to demonstrate to men how little they really know about what they imagine](https://reader031.vdocument.in/reader031/viewer/2022032705/56649da95503460f94a97044/html5/thumbnails/4.jpg)
The basic economic questions which every society faces
• PPF• Opportunity cost • Pareto optimal• Positive versus normative
![Page 5: Health Economics Taggert J. Brooks Spring 2013. “The curious task of economics is to demonstrate to men how little they really know about what they imagine](https://reader031.vdocument.in/reader031/viewer/2022032705/56649da95503460f94a97044/html5/thumbnails/5.jpg)
Research in Economics
• RAND Health Experiment– Gold standard, randomized treatments
![Page 6: Health Economics Taggert J. Brooks Spring 2013. “The curious task of economics is to demonstrate to men how little they really know about what they imagine](https://reader031.vdocument.in/reader031/viewer/2022032705/56649da95503460f94a97044/html5/thumbnails/6.jpg)
What is special about Health (Care) Economics?
• Uncertainty and Incomplete Information• Asymmetric Information• Regulation and Government Intervention• Externalities
![Page 7: Health Economics Taggert J. Brooks Spring 2013. “The curious task of economics is to demonstrate to men how little they really know about what they imagine](https://reader031.vdocument.in/reader031/viewer/2022032705/56649da95503460f94a97044/html5/thumbnails/7.jpg)
Uncertainty and Incomplete Information
• Random illness striking individuals• Random outcomes from medical
interventions• Professional uncertainty about efficacy of
treatment
![Page 8: Health Economics Taggert J. Brooks Spring 2013. “The curious task of economics is to demonstrate to men how little they really know about what they imagine](https://reader031.vdocument.in/reader031/viewer/2022032705/56649da95503460f94a97044/html5/thumbnails/8.jpg)
Asymmetric Information
• Health professional know more about the healing process and the efficacy of different treatments
• Consumers know more about their own health condition than insurers
• Physician Agency
![Page 9: Health Economics Taggert J. Brooks Spring 2013. “The curious task of economics is to demonstrate to men how little they really know about what they imagine](https://reader031.vdocument.in/reader031/viewer/2022032705/56649da95503460f94a97044/html5/thumbnails/9.jpg)
Regulation and Government Intervention
• Health Practitioners (Licensure)• Drugs and Products• Price Controls• Capital Construction, entry, and exit• Provision of insurance• Research and Development• Professional Education• Favored Tax Treatment
![Page 10: Health Economics Taggert J. Brooks Spring 2013. “The curious task of economics is to demonstrate to men how little they really know about what they imagine](https://reader031.vdocument.in/reader031/viewer/2022032705/56649da95503460f94a97044/html5/thumbnails/10.jpg)
Externalities
• Negative– Communicable Diseases– Reckless Lifestyles (e.g., Drunk Driving)– Gun Ownership
• Positive– Production of Knowledge
![Page 11: Health Economics Taggert J. Brooks Spring 2013. “The curious task of economics is to demonstrate to men how little they really know about what they imagine](https://reader031.vdocument.in/reader031/viewer/2022032705/56649da95503460f94a97044/html5/thumbnails/11.jpg)
Medical Care vs. Health Care
• Most of the improvement in life expectancy comes from public health– Chlorinated and Filtered water.
• Effect of medical care on health– Limited– Extensive versus Intensive Margins
![Page 12: Health Economics Taggert J. Brooks Spring 2013. “The curious task of economics is to demonstrate to men how little they really know about what they imagine](https://reader031.vdocument.in/reader031/viewer/2022032705/56649da95503460f94a97044/html5/thumbnails/12.jpg)

Grossman Model
• Economists think about Health in terms of a stock of Health.– The stock of health generates flow of utility
increasing life – Medical Care is an investment in that stock– Other investments
![Page 15: Health Economics Taggert J. Brooks Spring 2013. “The curious task of economics is to demonstrate to men how little they really know about what they imagine](https://reader031.vdocument.in/reader031/viewer/2022032705/56649da95503460f94a97044/html5/thumbnails/15.jpg)
Preconceptions
• Health Care Spending as % of GDP
• Government’s Share of Health Care Spending
• % of people covered by health insurance
• Life Expectancy at Birth.
