, surplus labour is usually "unpaid labour". Marxian economics regards surplus labour as the ultimate source of capitalist profits.

Origin of surplus labour

Marx explains the origin of surplus labour in the following terms:
The historical emergence of surplus labour is, according to Marx, also closely associated with the growth of trade
Trade
Trade is the transfer of ownership of goods and services from one person or entity to another. Trade is sometimes loosely called commerce or financial transaction or barter. A network that allows trade is called a market. The original form of trade was barter, the direct exchange of goods and...

 can be produced, the moral-political question arises as to how it should be distributed, and for whose benefit surplus-labour should be performed. The strong defeat the weak, and it becomes possible for a social elite to gain control over the surplus-labour and surplus product of the working population; they can live off the labour of others.

Labour which is sufficiently productive so that it can perform surplus labour is, in a cash economy, the material foundation for the appropriation of surplus-value from that labour. How exactly this appropriation will occur, is determined by the prevailing relations of production

According to Marx, capital had its origin in the commercial activity of buying in order to sell, with the aim of gaining an income (a surplus value) from this trade. But, initially, this does not involve any capitalist mode of production
Capitalist mode of production

; rather, the merchant traders are intermediaries between non-capitalist producers. During a lengthy historical process, the old ways of extracting surplus labour are gradually replaced by commercial forms of exploitation.

Surplus labour and exploitation

Exploitation occurs when those appropriating surplus labour — whether in the form of surplus-value, surplus product or direct surplus labour — are different than those performing surplus labour. Just as there are attempts to force more work out of the workers, there are also attempts at resistance to exploitation, e.g. strike action

 campaigns, living wage campaigns, go-slows, refusal to perform tasks not contracted for, threatening to leave employment for another job if that is a real possibility, etc. Critical variables in determining the total surplus labour performed are:
  • the length of the working day (and week): in other words, the total amount of time worked over a regular period
  • the intensity of work
  • the productiveness of the work (which also depends on the technologies used)
  • the subsistence level for workers
  • the position of strength or weakness of employers and employees
  • the level of unemployment
    Unemployment
    Unemployment , as defined by the International Labour Organization, occurs when people are without jobs and they have actively sought work within the past four weeks...

, Marx portrays the battle over work-time as the fulcrum of class conflict in capitalism, which can involve complex trade-offs between time and money. However, contrary to many Marxists, Marx never believed that exploitation at the point of production was the only kind of exploitation that exists.

Surplus labour in capitalist society

In feudal society, it was often quite clear how many days a serf or peasant worked for himself or herself (necessary labour), and how many days s/he worked for his or her lord (surplus labour). On this important distinction between a corvée

, the distinction between necessary labour and surplus labour however becomes obscured by the nature of the market transactions involved. Most people are legally free agents who can buy and sell labour on the basis of more or less equal access to markets, and an equal opportunity to better their lot in competition with others. Yet, owners of substantial property assets enter the market with an advantage over propertyless people who simply have to sell their labour to survive. It gives property owners the power to command the surplus labour of others. When the wage contract is signed, it appears that the employee is paid for the hours that he works, but at the same time, Marx argues, the worker adds an amount of value on the job in excess of the value of his wage/salary: he performs surplus labour.

In hiring an employee, the employer thus not only incurs a cost (the wage-bill, based on hours worked) but also reaps a benefit, namely the extra value the employee creates (the surplus product

 income after deduction of costs, but the only real evidence that surplus labour is the cause of it, is that the value of output produced is higher than the value of inputs used to produce it. The economic relation of necessary and surplus labour has therefore become hidden, and the division of enterprise revenues between wages, profits and taxes seems to become a purely distributional issue; just how exactly that new value originated, could be theorised about in all sorts of ways (see factors of production

, but for most of humanity, work is an absolute necessity, and consequently most people are concerned with the real benefits they get from that work. They may accept a certain rate of exploitation of their labour as an inescapable condition for their existence, if they depend on a wage or salary, but beyond that, they will increasingly resist it. Consequently, a morality

, gross mistreatment of workers etc. are no longer generally acceptable, although they continue to occur; working conditions and pay levels can usually be contested in courts of law.

Surplus labour and unequal exchange

Marx acknowledged that surplus labour may not just be appropriated directly in production by the owners of the enterprise, but also in trade. This phenomenon is nowadays called unequal exchange
Unequal exchange
Unequal exchange is a much disputed concept which is used primarily in Marxist economics, but also in ecological economics, to denote forms of exploitation hidden in or underwriting trade...

. Thus, he commented that:
In this case, more work effectively exchanges for less work, and a greater value exchanges for a lesser value, because some possess a stronger market position, and others a weaker one. For the most part, Marx assumed equal exchange in Das Kapital

, i.e. that supply and demand would balance; his argument was that even if, ideally speaking, no unequal exchange occurred in trade, and market equality existed, exploitation could nevertheless occur within capitalist relations of production

, since the value of the product produced by labour power exceeded the value of labour power itself. Marx never completed his analysis of the world market however.

 argue, unequal exchange occurs all the time, implying transfers of value from one place to another, through the trading process. Thus, the more trade becomes "globalised", the greater the intermediation between producers and consumers; consequently, the intermediaries appropriate a growing fraction of the final value of the products, while the direct producers obtain only a small fraction of that final value.

The most important unequal exchange in the world economy nowadays concerns the exchange between agricultural goods and industrial goods, i.e. the terms of trade

 already noted, this has meant that more and more agricultural output must be produced and sold, to buy a given amount of industrial goods. This issue has become the subject of heated controversy at recent WTO meetings.

The practice of unequal or unfair exchange does not presuppose the capitalist mode of production

Modern criticism of Marx's concept of surplus labour

According to economist Fred Moseley, "neoclassical economic theory was developed, in part, to attack the very notion of surplus labour or surplus value and to argue that workers receive all of the value embodied in their creative efforts." http://www.mtholyoke.edu/courses/sgabriel/surplus_labor_defined.htm

Some basic modern criticisms of Marx's theory can be found in the works by Pearson, Dalton, Boss, Hodgson and Harris (see references).

. He proves that this theorem is logically false. However, Marx himself never argued that surplus labour was a sufficient condition for profits, only an ultimate necessary condition (Morishima aimed to prove that,starting from the existence of profit expressed in price terms, we can deduce the existence of surplus value as a logical consequence). Five reasons were that:
  • profit in a capitalist operation was "ultimately" just a financial claim to products and labour services made by those who did not themselves produce those products and services, in virtue of their ownership of private property
    Private property

     (capital assets).
  • profits could be made purely in trading processes, which themselves could be far removed in space and time from the co-operative labour which those profits ultimately presupposed.
  • surplus labour could be performed, without this leading to any profits at all, because e.g. the products of that labour failed to be sold.
  • profits could be made without any labour being involved, such as when a piece of unimproved land is sold for a profit.
  • profits could be made by a self-employed operator who did not perform surplus labour for somebody else, nor necessarily appropriated surplus labour from anywhere else.


All that Marx really argued was that surplus labour was a necessary feature of the capitalist mode of production

) that Marxists may have overrated the importance of industrial surplus labour performed by salaried employees, because the very ability to perform that surplus-labour, i.e. the continual reproduction of labour power depends on all kinds of supports involving unremunerated work (for a theoretical discussion, see the reader by Bonnie Fox). In other words, work performed in households — often by those who do not sell their labour power to capitalist enterprises at all — contributes to the sustenance of capitalist workers who may perform little household labour.

Possibly the controversy about the concept is distorted by the enormous differences with regard to the world of work:
  • in Europe, the United States, Japan and Australasia,
  • the newly industrialising countries, and
  • the poor countries.
