What a Price System Can and Cannot Do A perfectly competitive price system can
allocate resources efficiently through the interaction of markets.

economy leads to too few or too many resources going to a specific economic activity

What a Price System Can and Cannot Do Market failure prevents economic
efficiency. Market failure prevents individual freedom. Public policy (government) is often called
upon to address market failure.

The Other Economic Functions of Government Providing Public Goods
Goods to which the principle of rival consumption does not apply
In contrast, private goods can be consumed by one individual at a time.

The Other Economic Functions of Government Characteristics of public goods
Indivisible Additional people can use public goods at no
additional cost Additional users of public goods do not deprive
other users Difficult to charge for a public good based on
consumption—the exclusion principle

Public Spending and Transfer Programs (cont'd) Publicly subsidized healthcare
Medicare Began in 1965 Pays hospital and physicians’ bills for U.S. residents
over 65 with public monies 2.9% of earnings taxed Second biggest domestic program in existence
Medicaid Subsidizes people with lower incomes

The Economic Effects of Medicare Subsidies To increase the quantity of medical care,
the government pays a subsidy.
The price per unit paid to medical service providers increases.
The price per unit paid by consumers falls.
More medical services are consumed.

Policy Example: Is the Medicare Program on the Fast Track to Bankruptcy?
Medicare spending is growing much faster than employer and employee contributions.
If both Medicare and federal tax collections continue to grow at present rates until 2050, Medicare will account for half of all federal tax collections.
![Page 21: Chapter 5: The Public Sector and Public Choice ECON 152 – PRINCIPLES OF MICROECONOMICS Materials include content from Pearson Addison-Wesley which has.](https://reader038.fdocuments.in/reader038/viewer/2022110100/56649e025503460f94aeccea/html5/thumbnails/21.jpg)
5-21
Policy Example: Is the Medicare Program on the Fast Track to Bankruptcy? (cont'd)
Because of the growth in program spending, Medicare will lack financial resources to cover promised benefits by 2019 or sooner.
Congress will have to increase taxes or cut benefits or both.
![Page 22: Chapter 5: The Public Sector and Public Choice ECON 152 – PRINCIPLES OF MICROECONOMICS Materials include content from Pearson Addison-Wesley which has.](https://reader038.fdocuments.in/reader038/viewer/2022110100/56649e025503460f94aeccea/html5/thumbnails/22.jpg)

Policy Example: Is the Medicare Program on the Fast Track to Bankruptcy? (cont'd)

Economic Issues of Public Education State and local governments provide
primary, secondary, and post-secondary education at prices well below those that would otherwise prevail in the marketplace.
![Page 24: Chapter 5: The Public Sector and Public Choice ECON 152 – PRINCIPLES OF MICROECONOMICS Materials include content from Pearson Addison-Wesley which has.](https://reader038.fdocuments.in/reader038/viewer/2022110100/56649e025503460f94aeccea/html5/thumbnails/24.jpg)

Economic Issues of Public Education (cont'd) Economics of public education
Publicly subsidized, similar to government subsidized healthcare
Education priced below market
![Page 25: Chapter 5: The Public Sector and Public Choice ECON 152 – PRINCIPLES OF MICROECONOMICS Materials include content from Pearson Addison-Wesley which has.](https://reader038.fdocuments.in/reader038/viewer/2022110100/56649e025503460f94aeccea/html5/thumbnails/25.jpg)
5-25
Economic Issues of Public Education (cont'd) Incentive problems of public education
Various measures of performance show no increase or decline in performance.
Many economists argue failure to improve relies on incentive effects.
Higher subsidies may translate to services unrelated to learning.

Policy Example: What Have Public Schools Done with Subsidies?
Public school enrollments have increased 40% since 1960.
Inflation-adjusted spending per student has increased 200%.
Teachers have increased by 60%.
![Page 27: Chapter 5: The Public Sector and Public Choice ECON 152 – PRINCIPLES OF MICROECONOMICS Materials include content from Pearson Addison-Wesley which has.](https://reader038.fdocuments.in/reader038/viewer/2022110100/56649e025503460f94aeccea/html5/thumbnails/27.jpg)
5-27
Policy Example: What Have Public Schools Done with Subsidies? (cont'd)
Overall, number of non-teaching staff increased 500%.
As predicted by the basic economics of subsidies, schools have allocated funds to activities contributing little to student learning.
