2. What Is a Public Good?
Non-rivalrous consumption: Consumption of the good by some persons does not reduce its availability to others
Non-excludable: People who do not pay for it cannot be excluded from using or benefiting from it

3. Examples and Free Riding
Very few pure public goods
But many which are almost public goods in most places: fresh air, many kinds of knowledge, national defence, language, broadcast radio or TV, street lighting, municipal parks, etc.
Public goods suffer from free-rider or easy rider problem, and therefore tend to be under-produced

4. Definitions Excludable Non-Excludable Rivalrous Private Goods
Food, clothing, shoes, parking space
Common Goods
Fish stocks, timber, coal, busy road
Non-Rivalrous
Club Goods
Cinema, private parks, satellite television
Public Goods
Broadcast TV, air, national defence, quiet, beauty

6. Important Caveat to Market Economics
Most discussion limited to private goods in competitive markets
There are important situations where pursuit of private self-interest (in markets) does not lead to desirable outcomes
For example:
Public goods
Non-exclusion of non-payers
Zero marginal cost
Monopoly/Monopsony
Information asymmetry (Lemons, agency)
It would be unwise to assume that properties of competitive markets for private goods extend to public goods or non-competitive markets. They don’t, because of free riding behavior:

11. Let Us Talk about Education
Education is, at least in part, a public good
With limited capacity, and control of admissions, it has been turned into largely a private good
But why are 40% of the positions of teachers in higher education in India unfilled
Education of teachers/scholars: expensive, need high talent, no money in it  therefore under-produced

12. Look Closer
How Many Students in Your Classes Dream of Becoming Teachers?
What is the average quality of students who choose teaching careers?
What is their compensation and social status?

13. Wisdom on Education?
Urging the VCs to strictly adhere to the academic calendar, Kovind said, "Vacancies should be filled quickly and urgently. Vacancies in teaching staff are unfair on students who have enrolled, and a disservice to their education."
Suggesting that retired professors be engaged for specific periods to fill vacancies, Kovind said that planning for impending vacancies should be done months in advance. Calling the VCs "chief executive" of their universities, the President added that as custodians of public funds, enforcing financial discipline and maintenance of accounts was "important".
"Where possible, it may be prudent to bring in officers from the central services as registrars and financial officers. This would help ensure certain standards," he added.

14. What can be done?
To increase the quality and quantity of young talent entering teaching and scholarship?
No retirement age?
Appraisal of faculty: bringing best students to academia
Educate students about teaching careers
Private institutes to create role models
Strengthen PhD programs
Increase pay package, academic career plan with challenges and exposure
