Where does commodity collide?

In economics, a good brought to market for exchange and treated as interchangeable across producers, so that one seller's unit substitutes for another's at a common price. Adam Smith's 1776 An Inquiry into the Nature and Causes of the Wealth of Nations separated a good's value in use from its value in exchange and described how goods trade at market prices set by supply and demand. Later economics sharpened this into the modern idea of a standardized, fungible good, such as a bushel of wheat or a barrel of oil, whose quality is graded so units count as equivalent. The referent is a class of tradable good defined by its interchangeability, not the social form a good takes under a given economic system, nor the market process by which a product loses its distinctiveness.[1]

Unit

One interchangeable unit of a graded good, priced by supply and demand

Recovery means

Not applicable

Measured by

Tracked by market price, traded volume, and grade or quality standards

In Marxist political economy, a good produced not for the maker's own use but for exchange, whose exchange value, in Marx's account, reflects the socially necessary labor embodied in it. Karl Marx's 1867 Das Kapital opened with an analysis of the commodity and introduced commodity fetishism, the idea that relations between the people who produce and exchange goods come to appear as relations between the goods themselves. In this usage the commodity is a social form a product takes under a system of exchange, and the analysis concerns how value and social labor are represented in it. The referent is this social form and its place in a theory of value, not a fungible unit priced in a market, nor a product that has lost its differentiation.[2]

Unit

A product in its exchange form, analyzed by the labor it is held to embody

Recovery means

Not applicable

Measured by

Examined theoretically through value, exchange value, and embodied labor time rather than by direct measurement

In marketing, commoditization is the process by which a product loses the features that set it apart, so that buyers come to see rival offerings as equivalent and choose mainly on price. Theodore Levitt's 1980 article Marketing success through differentiation of anything in the Harvard Business Review argued that almost any product can be differentiated and warned against letting an offering collapse into an undifferentiated good competing only on price. Here the word names a market dynamic that firms try to resist through branding, service, and added features, rather than a fixed property of the good. The referent is this movement toward sameness in a market, not a tradable good defined by its interchangeability, nor a social form studied in a theory of value.[3]

Unit

One product's drift toward being seen as interchangeable with its rivals

Recovery means

Firms counter it through differentiation such as branding, service, and added features

Measured by

Indicated by falling price premiums, price-driven choice, and reduced perceived difference between brands
