The Labor Theory of Value (LTV) is a classical economic theory which posits that the value of a good or service is primarily determined by the amount of socially necessary labor required to produce it. This theory has been a cornerstone in the works of early economists such as Adam Smith, David Ricardo, and Karl Marx.
Historical Context and Proponents
Adam Smith
Adam Smith, often recognized as the father of modern economics, introduced the idea that labor is the true source of value in his seminal work, “The Wealth of Nations.” He argued that the value of a commodity could be measured by the quantity of labor required to produce it.
David Ricardo
David Ricardo expanded on Smith’s ideas in his book, “Principles of Political Economy and Taxation.” Ricardo introduced the concept of “labor embodied” in goods, contrasting with Smith’s “labor commanded.”
Karl Marx
Karl Marx further developed the LTV in his critique of political economy, particularly in “Das Kapital.” Marx argued that labor is the source of all value but that workers are not fully compensated for their labor, leading to surplus value extracted by capitalists.
Key Concepts of the Labor Theory of Value
Socially Necessary Labor Time
Socially necessary labor time is the average amount of time required to produce a given commodity under normal conditions of production and with the average degree of skill and intensity prevalent at the time.
Surplus Value
Surplus value is a central concept in Marxian economics, describing the difference between the value produced by labor and the actual wage paid to the laborer. This surplus is seen as the source of profit for capitalists.
Commodities and Exchange Value
According to LTV, commodities have both use value and exchange value. The use value refers to their utility, while exchange value is determined by the amount of socially necessary labor time.
Examples and Applications
Example
Consider a chair that takes 5 hours to make by an average worker using standard tools. According to LTV, the value of the chair is equivalent to the value of 5 hours of labor.
Application in Modern Economics
Though LTV has been largely supplanted by marginal utility theory in mainstream economics, it remains influential in heterodox economics, particularly in Marxist and socialist theories of value.
Comparisons and Related Terms
Marginal Utility Theory
Unlike LTV, marginal utility theory suggests that value is determined by the utility or satisfaction a consumer receives from an additional unit of a good or service.
Cost of Production Theory
This theory posits that the value of a good is determined by the costs of the inputs needed to produce it, including labor, capital, and materials.

Summary
The Labor Theory of Value has been a significant element in the evolution of economic thought, from Adam Smith to Karl Marx. While no longer the dominant theory in mainstream economics, its concepts remain crucial for understanding the historical and theoretical underpinnings of value and labor in economic systems.
