labour theory of value

Quick Summary

The labor theory of value is an economic concept suggesting that the value of a product is determined by the amount of labor required to produce it. This theory was notably utilized by Karl Marx to argue that labor is the sole source of economic value. Marx contended that capitalists exploit workers by paying them only enough for subsistence, while appropriating the remaining value created by the worker's labor as "surplus value".1

Earlier economists, like David Ricardo, also explored variations of this idea, often linking wages to subsistence levels. However, attempts to establish a direct, quantifiable relationship between the value of a product and the precise quantity of labor involved have proven difficult, as labor itself varies in skill, training, and other factors. The theory posits that the value of labor is determined by the amount of socially necessary labor time required for production.2345
