Socialism is an economic and political philosophy encompassing diverse economic and social systems characterised by social ownership of the means of production, as opposed to private ownership. It describes the economic, political, and social theories and movements associated with the implementation of such systems. Social ownership can take various forms, including public, community, collective, cooperative, or employee. Traditionally, socialism is on the left wing of the political spectrum. Types of socialism vary based on the role of markets and planning in resource allocation, and the structure of management in organizations.

Market socialism is a type of economic system involving social ownership of the means of production within the framework of a market economy. Various models for such a system exist, usually involving cooperative enterprises and sometimes a mix that includes public or private enterprises. In contrast to the majority of historic socialist economies, which have substituted the market mechanism for some form of economic planning, market socialists wish to retain the use of supply and demand signals to guide the allocation of capital goods and the means of production. Under such a system, depending on whether socially owned firms are state-owned or operated as worker cooperatives, profits may variously be used to directly remunerate employees, accrue to society at large as the source of public finance, or be distributed amongst the population in a social dividend.
