Market Failures and Government Intervention

Externalities

Negative Externalities: Occur when the production or consumption of a good directly affects consumers or businesses not involved in the transaction, and this impact is not reflected in market prices. Pollution is a classic example, leading to overproduction from a societal perspective.

Positive Externalities: Arise when the social benefit of producing a good exceeds the private benefit. This often leads to underproduction in the market.

Public Goods

These goods are non-excludable (everyone can enjoy them) and non-rivalrous (one person's consumption doesn't diminish another's).

Private Goods

Characterized by rivalry (one person's consumption prevents another's) and excludability (those who don't pay can be excluded).

Free-Rider Problem

When individuals can benefit from a good without paying, they have an incentive to act as free-riders, letting others bear the cost.

Common Resources

These goods are rivalrous (one person's use diminishes another's) but non-excludable (difficult to prevent access).

Imperfect Information

When consumers or producers lack sufficient information to make well-informed decisions.

Asymmetric Information

Occurs when one party in a transaction has more information than the other, potentially leading to inefficient outcomes.

Distributive Politics

Government actions aimed at influencing the distribution of income to promote equity.

Taxes

Direct Taxes: Levied on income.

Indirect Taxes: Levied on consumption.

Transfers

Payments from the public sector to citizens or businesses without requiring goods or services in return.

Welfare State

Represents government intervention to protect individuals from hardship and guarantee a minimum standard of living.
