Participatory economics in the context of "Economic freedom"

A planned economy is a type of economic system where investment, production and the allocation of capital goods takes place according to economy-wide economic plans and production plans. A planned economy may use centralized, decentralized, participatory or Soviet-type forms of economic planning. The level of centralization or decentralization in decision-making and participation depends on the specific type of planning mechanism employed.

Socialist states based on the Soviet model have used central planning, although a minority such as the former Socialist Federal Republic of Yugoslavia have adopted some degree of market socialism. Market abolitionist socialism replaces factor markets with direct calculation as the means to coordinate the activities of the various socially owned economic enterprises that make up the economy. More recent approaches to socialist planning and allocation have come from some economists and computer scientists proposing planning mechanisms based on advances in computer science and information technology.

Citizen participation or public participation in social science refers to different mechanisms for the public to express opinions—and ideally exert influence—regarding political, economic, management or other social decisions. Participatory decision-making can take place along any realm of human social activity, including economic (i.e. participatory economics), political (i.e. participatory democracy or parpolity), management (i.e. participatory management), cultural (i.e. polyculturalism) or familial (i.e. feminism).

For well-informed participation to occur, it is argued that some version of transparency, e.g. radical transparency, is necessary but not sufficient. It has also been argued that those most affected by a decision should have the most say while those that are least affected should have the least say in a topic.

Workers' control is participation in the management of factories and other commercial enterprises by the people who work there. It has been variously advocated by anarchists, socialists (notably Trotskyists), communists, social democrats, distributists and Christian democrats, and has been combined with various socialist and mixed economy systems.

Workers' councils are a form of workers' control. Council communism, such as in the early Soviet Union, advocates workers' control through workers' councils and factory committees. Syndicalism advocates workers' control through trade unions. Guild socialism advocates workers' control through a revival of the guild system. Participatory economics represents a recent variation on the idea of workers' control.
