Government Intervention: Regulation and Legislation

While taxation and subsidies work through the price mechanism, regulation and legislation take a more direct, command-and-control approach to correcting market failure. Governments can set legally binding rules that restrict or mandate certain behaviours, control prices, limit quantities, or establish standards. These interventions bypass the price mechanism entirely, imposing legal requirements backed by penalties.

Key Definition: Regulation is the use of laws, rules, and standards imposed by government or regulatory bodies to control the behaviour of firms and individuals in order to correct market failure or achieve policy objectives.

Types of Regulatory Intervention

1. Minimum Prices (Price Floors)

A minimum price is a legally imposed price below which a good or service cannot be sold. It is effective only when set above the free market equilibrium price.

Examples:

• National Minimum Wage (NMW) / National Living Wage (NLW) — In April 2024, the NLW for workers aged 21 and over was £11.44 per hour. The purpose is to prevent exploitation of workers and reduce in-work poverty. The Low Pay Commission advises the government on appropriate rates.
