Market intervention

A market intervention is a policy or measure that modifies or interferes with a market, typically done in the form of state action, but also by philanthropic and political-action groups. Market interventions can be done for a number of reasons, including as an attempt to correct market failures,^[1] or more broadly to promote public interests or protect the interests of specific groups.

Economic interventions can be aimed at a variety of political or economic objectives, including but not limited to promoting economic growth, increasing employment, raising wages, raising or reducing prices, reducing income inequality, managing the money supply and interest rates, or increasing profits. A wide variety of tools can be used to achieve these aims, such as taxes or fines, state owned enterprises, subsidies, or regulations such as price floors and price ceilings.
