Market socialism is a type of economic system involving the public, cooperative, or social ownership of the means of production in the framework of a market economy. Market socialism differs from non-market socialism in that the market mechanism is utilized for the allocation of capital goods and the means of production. Depending on the specific model of market socialism, profits generated by socially owned firms (i.e. net revenue not reinvested into expanding the firm) 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.
Although economic proposals involving social ownership with factor markets have existed since the early 19th century, the term "market socialism" only emerged in the 1920s during the socialist calculation debate. Contemporary market socialism emerged from the debate on socialist calculation during the early-to-mid 20th century among socialist economists who believed that a socialist economy could neither function on the basis of calculation in natural units nor through solving a system of simultaneous equations for economic coordination, and that capital markets would be required in a socialist economy.
