Overview
Market failure is a situation where the allocation of goods and services by a free market is not efficient, often leading to a net social welfare loss. Market failures are often associated with several factors such as external economies, incomplete or poorly enforced property rights, and monopolistic characteristics of suppliers. Understanding these failures is crucial for effective economic policy-making and ensuring optimal resource distribution.
Causes of Market Failure
-
External Economies: These are costs or benefits that affect third parties who are not involved in a transaction. For instance, pollution from a factory affects nearby residents negatively, an issue not accounted for in the market price.
-
Incomplete or Poorly Enforced Property Rights: When property rights are not well-defined or enforced, there is little incentive to use resources efficiently. For example, overfishing is common in international waters with weak property rights.
-
Monopolistic Characteristics: When a market is dominated by a single supplier or a small group of suppliers, they can influence prices and output levels, which may lead to inefficient resource allocation and a loss of consumer welfare.
Examples
- Pollution: Factories emitting pollutants into the air without bearing the full cost of their actions result in negative externalities.
- Public Goods: Items like national defense and public parks are non-excludable and non-rivalrous, often leading to underproduction in a free market.
- Healthcare: Asymmetric information between providers and consumers can lead to adverse selection and moral hazard, causing inefficient market outcomes.
Frequently Asked Questions
Q1: What is market failure? A1: Market failure occurs when the distribution of goods and services by a free market is inefficient, leading to a net loss of social welfare.
Q2: What are the main causes of market failure? A2: The main causes include external economies, incomplete or poorly enforced property rights, and monopolistic characteristics of suppliers.
Q3: Can government intervention always correct market failures? A3: While government intervention can help correct some market failures, it can sometimes lead to government failures if improperly executed.
Q4: How do external economies lead to market failure? A4: External economies lead to market failure because the full social costs or benefits are not reflected in market prices, resulting in over or under-consumption.
Q5: What role do property rights play in market failure? A5: Poorly defined or enforced property rights lead to inefficient use of resources because individuals do not bear the full cost or benefit of their actions.

- Monopoly: A market structure where a single seller dominates, often leading to economic inefficiency and higher prices for consumers.
- Asymmetric Information: A situation where one party in a transaction has more or better information than the other, leading to suboptimal outcomes.
