In economics, factors of production, resources, or inputs are what is used in the production process to produce output—that is, goods and services. The utilized amounts of the various inputs determine the quantity of output according to the relationship called the production function. There are four basic resources or factors of production: land, labour, capital and entrepreneur (or enterprise). The factors are also frequently labeled "producer goods or services" to distinguish them from the goods or services purchased by consumers, which are frequently labeled "consumer goods".
There are two types of factors: primary and secondary. The previously mentioned primary factors are land, labour and capital. Materials and energy are considered secondary factors in classical economics because they are obtained from land, labour, and capital. The primary factors facilitate production but neither becomes part of the product (as with raw materials) nor becomes significantly transformed by the production process (as with fuel used to power machinery). Land includes not only the site of production but also natural resources above or below the soil. Recent usage has distinguished human capital (the stock of knowledge in the labor force) from labor. Entrepreneurship is also sometimes considered a factor of production. Sometimes the overall state of technology is described as a factor of production. The number and definition of factors vary, depending on theoretical purpose, empirical emphasis, or school of economics.
In the interpretation of the currently dominant view of classical economic theory developed by neoclassical economists, the term "factors" did not exist until after the classical period and is not to be found in any of the literature of that time.
Differences are most stark when it comes to deciding which factor is the most important.
Physiocracy (from the Greek for "government of nature") is an economic theory developed by a group of 18th century Enlightenment French economists who believed that the wealth of nations was derived solely from the value of "land agriculture" or "land development" and that agricultural products should be highly priced.
The classical economics of Adam Smith, David Ricardo, and their followers focus on physical resources in defining its factors of production and discuss the distribution of cost and value among these factors. Adam Smith and David Ricardo referred to the "component parts of price" as the costs of using:
The classical economists also employed the word "capital" in reference to money. Money, however, was not considered to be a factor of production in the sense of capital stock since it is not used to directly produce any good. The return to loaned money or to loaned stock was styled as interest while the return to the actual proprietor of capital stock (tools, etc.) was styled as profit. See also returns.
Marx considered the "elementary factors of the labor-process" or "productive forces" to be:
The "subject of labor" refers to natural resources and raw materials, including land. The "instruments of labor" are tools, in the broadest sense. They include factory buildings, infrastructure, and other human-made objects that facilitate labor's production of goods and services.
This view seems similar to the classical perspective described above. But unlike the classical school and many economists today, Marx made a clear distinction between labor actually done and an individual's "labor power" or ability to work. Labor done is often referred to nowadays as "effort" or "labor services." Labor-power might be seen as a stock which can produce a flow of labor.
Labor, not labor power, is the key factor of production for Marx and the basis for Marx's labor theory of value. The hiring of labor power only results in the production of goods or services ("use-values") when organized and regulated (often by the "management"). How much labor is actually done depends on the importance of conflict or tensions within the labor process.
Neoclassical economics, one of the branches of mainstream economics, started with the classical factors of production of land, labor, and capital. However, it developed an alternative theory of value and distribution. Many of its practitioners have added various further factors of production (see below).
Further distinctions from classical and neoclassical microeconomics include the following:
Ecological economics is an alternative to neoclassical economics. It integrates, among other things, the first and second laws of thermodynamics (see: Laws of thermodynamics) to formulate more realistic economic systems that adhere to fundamental physical limitations. In addition to the neoclassical focus on efficient allocation, ecological economics emphasizes sustainability of scale and just distribution. Ecological economics also differ from neoclassical theories in its definitions of factors of production, replacing them with the following:
Integral to ecological economics is the following notion: at the maximum rates of sustainable matter and energy uptake, the only way to increase productivity would be through an increase in design intelligence. This provides the basis for a core tenet of ecological economics, namely that infinite growth is impossible.
In the first half of the 20th century, some authors added the work of organization or entrepreneurship as a fourth factor of production. This became standard in the post-war Neoclassical synthesis. For example, J. B. Clark saw the co-ordinating function in production and distribution as being served by entrepreneurs; Frank Knight introduced managers who co-ordinate using their own money (financial capital) and the financial capital of others. In contrast, many economists today consider "human capital" (skills and education) as the fourth factor of production, with entrepreneurship as a form of human capital. Yet others refer to intellectual capital. More recently, many have begun to see "social capital" as a factor, as contributing to production of goods and services.
In markets, entrepreneurs combine the other factors of production, land, labor, and capital, to make a profit. Often these entrepreneurs are seen as innovators, developing new ways to produce new products. In a planned economy, central planners decide how land, labor, and capital should be used to provide for maximum benefit for all citizens. Just as with market entrepreneurs, the benefits may mostly accrue to the entrepreneurs themselves.
The sociologist C. Wright Mills refers to "new entrepreneurs" who work within and between corporate and government bureaucracies in new and different ways. Others (such as those practicing public choice theory) refer to "political entrepreneurs", i.e., politicians and other actors.
Much controversy rages about the benefits produced by entrepreneurship. But the real issue is about how well institutions they operate in (markets, planning, bureaucracies, government) serve the public. This concerns such issues as the relative importance of market failure and government failure.
In the book Accounting of Ideas, "intequity", a neologism, is abstracted from equity to add a newly researched production factor of the capitalist system. Equity, which is regarded as part of capital, was divided into equity and inequity. Entrepreneurship was divided into network-related matters and creating-related matters. Network-related matters function in the sphere of equity, and creating-related matters in spheres of intequities.
Ayres and Warr (2010) are among the economists who criticize orthodox economics for overlooking the role of natural resources and the effects of declining resource capital. See also: Natural resource economics
Exercise can be seen as individual factor of production, with an elastication larger than labor. A cointegration analysis support results derived from linear exponential (LINEX) production functions.
C. H. Douglas disagreed with classical economists who recognized only three factors of production. While Douglas did not deny the role of these factors in production, he considered the “Cultural heritage” as the primary factor. He defined cultural inheritance as the knowledge, techniques, and processes that have accrued to us incrementally from the origins of civilization (i.e., progress). Consequently, mankind does not have to keep "reinventing the wheel". "We are merely the administrators of that cultural inheritance, and to that extent, the cultural inheritance is the property of all of us, without exception. Adam Smith, David Ricardo, and Karl Marx claimed that labor creates all value. While Douglas did not deny that all costs ultimately relate to labour charges of some sort (past or present), he denied that the present labour of the world creates all wealth. Douglas carefully distinguished between value, costs and prices. He claimed that one of the factors resulting in a misdirection of thought in terms of the nature and function of money was economists' near-obsession about values and their relation to prices and incomes. While Douglas recognized "value in use" as a legitimate theory of values, he also considered values as subjective and not capable of being measured in an objective manner.
Peter Kropotkin argued for the common ownership of all intellectual and useful property due to the collective work that went into creating it. Kropotkin does not argue that the product of a worker's labor should belong to the worker. Instead, Kropotkin asserts that every individual product is essentially the work of everyone since every individual relies on the intellectual and physical labor of those who came before them as well as those who built the world around them. Because of this, Kropotkin proclaims that every human deserves an essential right to well-being because every human contributes to the collective social product: Kropotkin goes on to say that the central obstacle preventing humanity from claiming this right is the state's violent protection of private property. Kropotkin compares this relationship to feudalism, saying that even if the forms have changed, the essential relationship between the propertied and the landless is the same as the relationship between a feudal lord and their serfs.
