Surplus product in the context of "Citizen ownership of equity"

Social ownership is a type of property where an asset is recognized to be in the possession of society as a whole rather than individual members or groups within it. Social ownership of the means of production is the defining characteristic of a socialist economy, and can take the form of community ownership, state ownership, common ownership, employee ownership, cooperative ownership, and citizen ownership of equity. Within the context of socialist economics it refers particularly to the appropriation of the surplus product produced by the means of production (or the wealth that comes from it) to society at large or the workers themselves. Traditionally, social ownership implied that capital and factor markets would cease to exist under the assumption that market exchanges within the production process would be made redundant if capital goods were owned and integrated by a single entity or network of entities representing society. However, the articulation of models of market socialism where factor markets are utilized for allocating capital goods between socially owned enterprises broadened the definition to include autonomous entities within a market economy.

The two major forms of social ownership are society-wide public ownership and cooperative ownership. The distinction between these two forms lies in the distribution of the surplus product. With society-wide public ownership, the surplus is distributed to all members of the public through a social dividend whereas with co-operative ownership the economic surplus of an enterprise is controlled by all the worker-members of that specific enterprise.

Marxian economics, or the Marxian school of economics, is a heterodox school of political economic thought. Its foundations can be traced back to Karl Marx's critique of political economy. However, unlike critics of political economy, Marxian economists tend to accept the concept of the economy prima facie. Marxian economics comprises several different theories and includes multiple schools of thought, which are sometimes opposed to each other; in many cases Marxian analysis is used to complement, or to supplement, other economic approaches. An example can be found in the works of Soviet economists like Lev Gatovsky, who sought to apply Marxist economic theory to the objectives, needs, and political conditions of the socialist construction in the Soviet Union, contributing to the development of Soviet political economy.

Marxian economics concerns itself variously with the analysis of crisis in capitalism, the role and distribution of the surplus product and surplus value in various types of economic systems, the nature and origin of economic value, the impact of class and class struggle on economic and political processes, and the process of economic evolution.

In Marxian economics, surplus value is the difference between the amount raised through a sale of a product and the amount it cost to manufacture it: i.e. the amount raised through sale of the product minus the cost of the materials, plant and labour power. The concept originated in Ricardian socialism, with the term "surplus value" itself being coined by William Thompson in 1824; however, it was not consistently distinguished from the related concepts of surplus labor and surplus product. The concept was subsequently developed and popularized by Karl Marx. Marx's formulation is the standard sense and the primary basis for further developments, though how much of Marx's concept is original and distinct from the Ricardian concept is disputed (see § Origin). Marx's term is the German word "Mehrwert", which simply means value added (sales revenue minus the cost of materials used up), and is cognate to English "more worth".

It is a major concept in Karl Marx's critique of political economy, and, like all of Marx's economic theories, lies outside the economic mainstream. Conventionally, value-added is equal to the sum of gross wage income and gross profit income. However, Marx uses the term Mehrwert to describe the yield, profit or return on production capital invested, i.e. the amount of the increase in the value of capital. Hence, Marx's use of Mehrwert has always been translated as "surplus value", distinguishing it from "value-added". According to Marx's theory, surplus value is equal to the new value created by workers in excess of their own labor-cost, which is appropriated by the capitalist as profit when products are sold. Marx thought that the gigantic increase in wealth and population from the 19th century onwards was mainly due to the competitive striving to obtain maximum surplus-value from the employment of labor, resulting in an equally gigantic increase of productivity and capital resources. To the extent that increasingly the economic surplus is convertible into money and expressed in money, the amassment of wealth is possible on a larger and larger scale (see capital accumulation and surplus product). The concept is closely connected to producer surplus.

In economics, an excess supply, economic surplus market surplus or briefly supply is a situation in which the quantity of a good or service supplied is more than the quantity demanded, and the price is above the equilibrium level determined by supply and demand. That is, the quantity of the product that producers wish to sell exceeds the quantity that potential buyers are willing to buy at the prevailing price. It is the opposite of an economic shortage (excess demand).

In cultural evolution, agricultural surplus in the Neolithic period is theorized to have produced a greater division of labor, resulting in social stratification and class.
