Reference excerpt

In economics, a price system is a system through which the valuations of any forms of property (tangible or intangible) are determined. All societies use price systems in the allocation and exchange of resources as a consequence of scarcity. Even in a barter system with no money, price systems are still utilized in the determination of exchange ratios (relative valuations) between the properties being exchanged. A price system may be either a regulated price system (such as a fixed price system) where prices are administered by an authority, or it may be a free price system (such as a market system) where prices are left to float "freely" as determined by supply and demand without the intervention of an authority. A mixed price system involves a combination of both regulated and free price systems.

History Price systems have been around as long as there has been economic exchanges. The price system has transformed into the system of global capitalism that is present in the early 21st century. The Soviet Union and other Communist states with a centralized planned economy maintained controlled price systems. Whether the ruble or the dollar is used in the economic system, the criterion of a price system is the use of money as an arbiter and usual final arbiter of whether a thing is done or not. In other words, few things are done without consideration for the monetary costs and the potential making of a profit in a price system.

Debate on socialism

The American economist Thorstein Veblen wrote a seminal tract on the development of the term as discussed in this article: The Engineers and the Price System. Its chapter VI, A Memorandum on a Practicable Soviet of Technicians discusses the possibility of socialist revolution in the United States comparable to that then occurring in Russia (the Soviets had not yet at that time become a state (USSR formed in 1922)). According to Bockman, the original conception of socialism involved the substitution of money as a unit of calculation and monetary prices as a whole with calculation in kind (or valuation based on natural units), with business and financial decisions replaced by engineering and technical criteria for managing the economy. Fundamentally, this meant that socialism would operate under different economic dynamics than those of capitalism and the price system. In the 1930s, the economists Oskar Lange and Abba Lerner developed a comprehensive model of a socialist economy that utilized a price system and money for the allocation of capital goods. In contrast to a free-market price system, "socialist" prices would be set by a planning board to equal the marginal cost of production to achieve neoclassical Pareto efficiency. Because this model of socialism relied upon money and administered prices as opposed to non-monetary calculation in physical magnitudes, it was labelled "market socialism". In effect, Oskar Lange conceded that calculations in a socialist system would have to be performed in value terms with a functioning price system rather than using purely natural or engineering criteria as in the classic concept of socialism.

Hayek

Austrian School economist Friedrich Hayek argued that a free price system allowed economic coordination via the price signals that changing prices send, which is regarded as one of his most significant and influential contributions to economics. In "The Use of Knowledge in Society" (1945), Hayek wrote, "The price system is just one of those formations which man has learned to use (though he is still very far from having learned to make the best use of it) after he had stumbled upon it without understanding it. Through it not only a division of labor but also a coordinated utilization of resources based on an equally divided knowledge has become possible. The people who like to deride any suggestion that this may be so usually distort the argument by insinuating that it asserts that by some miracle just that sort of system has spontaneously grown up which is best suited to modern civilization. It is the other way round: man has been able to develop that division of labor on which our civilization is based because he happened to stumble upon a method which made it possible. Had he not done so, he might still have developed some other, altogether different, type of civilization, something like the "state" of the termite ants, or some other altogether unimaginable type."

Worked examples

Example 1 — a first encounter with Price system

Start with the simplest possible case. Write down what Price system claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Price system before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Price system ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Price system

In research: Price system appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Price system in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Price system is common in secondary-school and first-year university syllabi. It links to neighbouring topics Capitalism, Economic systems, History of money, so understanding it makes those chapters shorter.
In everyday life: Look for Price system outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Price system in simple terms?

In economics, a price system is a system through which the valuations of any forms of property (tangible or intangible) are determined. All societies use price systems in the allocation and exchange of resources as a consequence of scarcity.

Why does Price system matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Price system?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
