Public Economics
Public Economics is the study of how governments affect the allocation of resources and impact economic outcomes through policy interventions. This field of economics focuses on understanding the role and behavior of government in markets and on developing policies to correct market failures.
Key Concepts
Market Failure: When markets fail to allocate resources efficiently, public intervention may be necessary to correct the market failure. Examples of market failures include externalities, public goods, and imperfect competition.
Public Goods: Public goods are non-rival and non-excludable, meaning no one can be excluded from using them and their use by one person does not diminish their availability to others. Examples of public goods include parks, street lighting, and national defense.
Externalities: Externalities occur when the actions of one party affect the welfare of others who are not involved in the transaction. Positive externalities, such as education, have benefits for society as a whole. Negative externalities, such as pollution, have costs for society as a whole.
Taxation: Taxation is a primary tool of governments to raise revenue for public goods and services. The efficiency and equity of taxation policies are key issues in public economics.
Public Expenditure: Governments use public expenditure to provide public goods, transfer payments, and subsidies to individuals and firms, and to finance infrastructure development. The efficiency and effectiveness of public expenditure are key issues in public economics.
Important Information

Actionable Items
Understanding the different types of market failure and policy interventions available will be important in analyzing public policy issues.
Recognizing the significance of taxation and public expenditure as tools of government intervention, and being able to evaluate their efficiency and effectiveness, is essential in analyzing public policy issues.
The practical applications of public economics are diverse and will require a strong economic foundation and analytical skills.
