Key Concepts in Economic Justice and Redistribution

Redistribution of wealth often seen as a government responsibility rather than relying solely on private charity.
Government intervention aims for fairer distribution of income, consumption, and wealth.
Reasons for government role:
- Subsidizing private altruism to correct under provision.
- Promoting social stability by reducing income disparities.
- Creating income support programs (e.g., poverty insurance).
- Supporting the right to a reasonable standard of living (Article 25, UN Declaration).

Externalities: Actions of one agent affect others, often not accounted for in markets.
Public goods: Non-rival and non-excludable, e.g., streetlights, national defense, lighthouses.
Individuals may misreport value due to inability to exclude non-payers, leading to under provision of public goods.
Governments provide public goods through taxation and can regulate to manage externalities.

Second Fundamental Theorem of Welfare Economics: Resource distribution can be separated from efficiency.
Can change resource distribution using lump sum taxes or transfers.
Practical implementation of equitable redistribution is challenging.
Asymmetric information affects redistribution effectiveness and may lead to inefficiencies.

Taxation is crucial for financing public goods and services, despite distortionary effects.
Can involve borrowing, expanding money supply, or user fees, each with limitations:
- User fees are infeasible for non-excludable public goods.
Criteria for evaluating taxes:
Equity: Fair sharing of tax burden.
- Benefit Principle: People should pay based on benefits received.
- Ability-to-Pay Principle: Taxes should relate to individual ability to pay.
Efficiency: Simple, low administrative costs preferred.
Visibility: Transparent taxes are more acceptable to the public.
