Summary and Exam Tips for Reasons for government intervention in markets
Reasons for government intervention in markets is a subtopic of Government microeconomic intervention (AS level), which falls under the subject Economics in the Cambridge International A Levels curriculum.
Government intervention in markets is primarily driven by market failure, where the free market fails to allocate resources efficiently. Key reasons include the non-provision of public goods, overconsumption of demerit goods, and underconsumption of merit goods. Public goods, like national defense and street lighting, suffer from the free rider problem, as individuals benefit without contributing to costs. Demerit goods, such as tobacco, are overconsumed due to their negative impact on health and productivity, prompting governments to impose regulations like smoking bans. Conversely, merit goods like healthcare are underconsumed because consumers undervalue their benefits, leading to government intervention to ensure broader access. Governments also control prices through mechanisms like maximum prices to make essentials affordable, rent controls for housing, and minimum prices to support farmers. These interventions aim to correct market failures and ensure equitable access to essential goods and services.
