, a commodity is any good or service produced by human labour and offered as a product for general sale on the market. Some other priced goods are also treated as commodities, e.g. human labor-power, works of art and natural resources, even although they may not be produced specifically for the market, or be non-reproducible goods.

Characteristics of commodity

In Marx's theory, a commodity is something that is bought and sold.

  • It has a use value because, by its intrinsic characteristics, it can satisfy some human need or want, physical or ideal. By nature this is a social use value, i.e. the object is useful not just to the producer but has a use for others generally.

  • It has an exchange value, meaning that a commodity can be traded for other commodities, and thus give its owner the benefit of others' labor (the labor done to produce the purchased commodity).

  • Price is then the monetary expression of exchange-value (but exchange value could also be expressed as a direct trading ratio between two commodities without using money, and goods could be priced using different valuations or criteria).

Illustration

To understand the concept of a commodity, consider a chair. It is a commodity if the chair is a tradable product of human work possessing a social use-value. By contrast, a fallen log of deadwood sat upon in the forest is not a commodity, as it was not produced by human work for the purpose of trade. A chair created by a hobbyist as a gift to someone is not a commodity. Nor is a chair a commodity (as a chair) if its only use would be as firewood (unless one purchases a chair specifically to chop it up for firewood). A chair that nothing could sit on, has no use-value, and cannot be a commodity. An ornamental chair might yet however, have value.

Historical origins of commodity trade

Commodity-trade, Marx argues, historically begins at the boundaries of separate economic communities based otherwise on a non-commercial form of production. Thus, producers trade in those goods of which those producers, have episodic or permanent surpluses

 to their own requirements, and they aim to obtain different goods with an equal value in return.

Marx refers to this as "simple exchange" which implies what Frederick Engels calls "simple commodity production

". At first, goods may not even be intentionally produced for the explicit purpose of exchanging them, but as a regular market for goods develops and a cash economy grows, this becomes more and more the case, and production increasingly becomes integrated in commodity trade.

Even so, in simple commodity production, not all inputs and outputs of the production process are necessarily commodities or priced goods, and it is compatible with a variety of different relations of production

 ranging from self-employment and family labour to serfdom and slavery. Typically, however, it is the producer himself who trades his surpluses.

However, as the division of labour

 becomes more complex, a class of merchants emerges which specialises in trading commodities, buying here and selling there, without producing products themselves, and parallel to this, property owners emerge who extend credit and charge rents. This process goes together with the increased use of money
Money
Money is any object or record that is generally accepted as payment for goods and services and repayment of debts in a given country or socio-economic context. The main functions of money are distinguished as: a medium of exchange; a unit of account; a store of value; and, occasionally in the past,...

, and the aim of merchants, bankers and rentiers becomes to gain income from the trade, by acting as intermediaries between producers and consumers.

The transformation of a labor-product into a commodity (its "marketing") is in reality not a simple process, but has many technical and social preconditions. These often include:
  • the existence of a reliable supply of a product, or at least a surplus or surplus product

    .
  • the existence of a social need for it (a market demand) that must be met through trade, or at any event cannot be met otherwise.
  • the legally sanctioned assertion of private ownership rights to the commodity.
  • the enforcement of these rights, so that ownership is secure.
  • the transferability of these private rights from one owner to another.
  • the right to buy and sell the commodity, and/or obtain (privately) and keep income from such trade
  • the (physical) transferability of the commodity itself, i.e. the ability to store, package, preserve and transport it from one owner to another.
  • the imposition of exclusivity of access to the commodity.
  • the possibility of the owner to use or consume the commodity privately.
  • guarantees about the quality and safety of the commodity, and possibly a guarantee of replacement or service, should it fail to function as intended.


Thus, the "commodification
Commodification

" of a good or service often involves a considerable practical accomplishment in trade. It is a process that may be influenced not just by economic or technical factors, but also political and cultural factors, insofar as it involves property rights, claims to access to resources, and guarantees about quality or safety of use.

"To trade or not to trade", that may be the question. The modern debate in this regard focuses often on intellectual property rights because ideas are increasingly becoming objects of trade, and the technology now exists to transform ideas into commodities much more easily.

In absolute terms, exchange values can also be measured as quantities of average labour-hours. By contrast, prices are normally measured in money-units. For practical purposes, prices are however usually preferable to labour-hours, as units of account, although in capitalist work processes the two are related to each other (see labor power

 and human labour power), and that what and how much is produced is largely determined by the response of producers to the "state of the market". Production is now explicitly engaged in for the purpose of market sales only, which implies both that its whole organisation is reshaped for this aim, and that people can meet their own needs by purchases in the market (rather than producing goods directly for their own consumption).

Forms of commodity trade

The 7 basic forms of commodity trade can be summarised as follows:
  • M-C (an act of purchase: a sum of money purchases a commodity)
  • C-M (an act of sale: a commodity is sold for money)
  • M-M' (a sum of money is lent out at interest to obtain more money, or, one currency or financial claim is traded for another)
  • C-C' (countertrade, in which a commodity trades directly for a different commodity, with money possibly being used as an accounting referent, for example, food for oil, or weapons for diamonds) (a commodity is sold for money, which buys another, different commodity with an equal or higher value) (money is used to buy a commodity which is resold to obtain a larger sum of money)
  • M-C...P...-C'-M' (money buys means of production

     and labour power used in production to create a new commodity, which is sold for more money than the original outlay).


The hyphens ("-") here refer to a transaction applying to an exchange involving goods or money; the dots in the last-mentioned circuit ("...") indicate that a value-forming process ("P") occurs in between purchase of commodities and the sales of different commodities. Thus, while at first merchants are intermediaries between producers and consumers, later capitalist production becomes an intermediary between buyers and sellers of commodities. In that case, the valuation of labour is determined by the value of its products.

s as businesspeople are interested in use-values primarily from the point of view of their money-making potential, i.e. their exchange-value; any useful object may in principle become an object of exchange and profit-making, although that may in practice take quite some doing. In simple terms, the primary concern of businesspeople here is commercial: the money they can obtain from owning or selling the commodity.

But if an increase in capital-value is to be realised, it is essential that sales of commodities occur. Consequently, the accumulation of capital must go together with the expansion of market sales of commodities. In that sense, businesspeople cannot be indifferent to the use-values in which they trade.

Cost structure of commodities

In considering the unit cost of a capitalistically produced commodity (in contrast to simple commodity production

     per unit.


These components reflect respectively labour costs, the cost of materials and operating expenses including depreciation, and generic profit.

In capitalism, Marx argues, commodity values are commercially expressed as the prices of production

 of commodities (cost-price + average profit). Prices of production are established jointly by average input costs and by the ruling profit margins applying to outputs sold. They reflect the fact that production has become totally integrated into the circuits of commodity trade, in which capital accumulation

 process, i.e. how an increase in capital-value occurs through production.

Likewise, in considering the gross output of capitalist production in an economy as a whole, Marx divides its value into these four components. He argues that the total new value added in production, which he calls the value product

, consists of the equivalent of variable capital, plus surplus value. Thus, the workers produce by their labor both a new value equal to their own wages, plus an additional new value which is claimed by capitalists by virtue of their ownership and supply of productive capital.

, regardless of religious belief. People must work, because work is the source of new value, profits and capital.

Pseudo-commodities

Marx acknowledged explicitly that not all commodities are products of human labour; all kinds of things can be traded "as if" they are commodities, so long as property rights can be attached to them. These are "fictitious commodities" or "pseudo-commodities" or "fiduciary commodities", i.e. their existence as commodities is only nominal or conventional. They may not even be tangible objects, but exist only ideally. A property right or financial claim, for instance, may be traded as a commodity.
