Definition
Market failures occur when the allocation of goods and services by a free market is not efficient, often due to externalities or public goods, which are non-excludable and non-rivalrous resources that individuals cannot be effectively excluded from using, leading to underproduction or overconsumption. Public goods, such as clean air or national defense, require collective action for provision and maintenance, as their benefits are available to all, regardless of individual contribution.
Summary
Market failures occur when the free market does not allocate resources efficiently, leading to negative outcomes for society. This can happen due to various reasons, including externalities, public goods, and monopolistic practices. Understanding these failures is crucial for implementing effective government interventions that can help correct inefficiencies and improve overall welfare. Public goods, characterized by their non-excludable and non-rivalrous nature, play a significant role in addressing market failures. However, the free rider problem complicates their provision, as individuals may benefit without contributing to their cost. By exploring these concepts, learners can appreciate the importance of public policy in promoting economic efficiency and social welfare.
