The labor theory of value (LTV) is a theory of value that argues that the exchange value of a good or service is determined by the total amount of "socially necessary labor" required to produce it. The contrasting system is typically known as the subjective theory of value.
Both David Ricardo and Karl Marx attempted to quantify and embody all labor components in order to develop a theory of the real, or natural, price of a commodity. [13] In either case, what is being addressed are general prices—i.e., prices in the aggregate, not a specific price of a particular good or service in a given circumstance.

[2] The Soviet Union and other Communist states with a centralized planned economy maintained controlled price systems. Whether the ruble or the dollar is ...
If, however, prices can fluctuate above or below value for all sorts of reasons, Marx's law of value is best seen as a "law of grand averages", an overall generalisation about economic exchange, and the quantitative relationships between labour hours worked and real prices charged for an output are best expressed in probabilistic terms.

[3] Labour markets or job markets function through the interaction of workers and employers. Labour economics looks at the suppliers of labour services (workers) and the ...
Uncultivated land has a price, even if there is no labor involved. The price of land is explained by the theory of rent. Both Ricardo and Marx developed theories of land-rent based on the LTV. Paper money—according to Marx, "[t]he function of gold as coin becomes completely independent of the metallic value of that gold.
Hazlitt explains how a society solves the problem of alternative applications of labor and capital by using the price system. [3] Prices are determined by supply and demand, and they affect supply and demand. The constant interrelationships of production costs, prices, and profits determine which commodities will be produced and in what quantities.
A related government intervention to price floor, which is also a price control, is the price ceiling; it sets the maximum price that can legally be charged for a good or service, with a common example being rent control. A price ceiling is a price control, or limit, on how high a price is charged for a product, commodity, or service.
