Classical economics in the context of "Labour theory of value"

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 utilised 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 become part of the product (as with raw materials) nor become 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 labour. 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.

Production is the process of combining various inputs, both material (such as metal, wood, glass, or plastics) and immaterial (such as plans, or knowledge) in order to create output. Ideally, this output will be a good or service which has value and contributes to the utility of individuals. The area of economics that focuses on production is called production theory, and it is closely related to the consumption (or consumer) theory of economics.

The production process and output directly result from productively utilising the original inputs (or factors of production). Known as land, labor, capital and entrepreneurship, these are deemed the four fundamental factors of production. These primary inputs are not significantly altered in the output process, nor do they become a whole component in the product. Under classical economics, materials and energy are categorised as secondary factors as they are byproducts of land, labour and capital. Delving further, primary factors encompass all of the resourcing involved, such as land, which includes the natural resources above and below the soil. However, there is a difference between human capital and labour. In addition to the common factors of production, in different economic schools of thought, entrepreneurship and technology are sometimes considered evolved factors in production. It is common practice that several forms of controllable inputs are used to achieve the output of a product. The production function assesses the relationship between the inputs and the quantity of output.

In the history of economic thought, a school of economic thought is a group of economic thinkers who share or shared a mutual perspective on the way economies function. While economists do not always fit within particular schools, particularly in the modern era, classifying economists into schools of thought is common. Economic thought may be roughly divided into three phases: premodern (Greco-Roman, Indian, Persian, Islamic, and Imperial Chinese), early modern (mercantilist, physiocrats) and modern (beginning with Adam Smith and classical economics in the late 18th century, and Karl Marx and Friedrich Engels' Marxian economics in the mid 19th century). Systematic economic theory has been developed primarily since the beginning of what is termed the modern era.

Currently, the great majority of economists follow an approach referred to as mainstream economics (sometimes called 'orthodox economics'). Economists generally specialize into either macroeconomics, broadly on the general scope of the economy as a whole, or microeconomics, on specific markets or actors.

The Economic and Philosophic Manuscripts of 1844 (German: Ökonomisch-philosophische Manuskripte aus dem Jahre 1844), also known as the Paris Manuscripts (Pariser Manuskripte) or as the 1844 Manuscripts, are a series of unfinished notes written between April and August 1844 by Karl Marx. They were compiled and published posthumously in 1932 by the Soviet Union's Marx–Engels–Lenin Institute. They were first published in their original German in Berlin, and there followed a republication in the Soviet Union in 1933, also in German.

The Manuscripts provide a critique of classical political economy grounded in the philosophies of Georg Wilhelm Friedrich Hegel and Ludwig Feuerbach. The work is best known for its articulation of Marx's argument that the conditions of modern industrial societies result in the estrangement (or alienation) of wage-workers from their own products, from their own work, and in turn from themselves and from each other. Marx argues that workers are forced by the capitalist productive process to work solely to satisfy their basic needs. As such, they merely exist as commodities in a constant state of drudgery, evaluated solely by their monetary value, with capital assuming the status of a good in and of itself.

The natural rate of unemployment is the name that was given to a key concept in the study of economic activity. Milton Friedman and Edmund Phelps, tackling this 'human' problem in the 1960s, both received the Nobel Memorial Prize in Economic Sciences for their work, and the development of the concept is cited as a main motivation behind the prize. A simplistic summary of the concept is: 'The natural rate of unemployment, when an economy is in a steady state of "full employment", is the proportion of the workforce who are unemployed'. Put another way, this concept clarifies that the economic term "full employment" does not mean "zero unemployment". It represents the hypothetical unemployment rate consistent with aggregate production being at the "long-run" level. This level is consistent with aggregate production in the absence of various temporary frictions such as incomplete price adjustment in labor and goods markets. The natural rate of unemployment therefore corresponds to the unemployment rate prevailing under a classical view of determination of activity.

The natural unemployment rate is mainly determined by the economy's supply side, and hence production possibilities and economic institutions. If these institutional features involve permanent mismatches in the labor market or real wage rigidities, the natural rate of unemployment may feature involuntary unemployment. The natural rate of unemployment is a combination of frictional and structural unemployment that persists in an efficient, expanding economy when labor and resource markets are in equilibrium.

David Ricardo (18 April 1772 – 11 September 1823) was a British economist and politician of Portuguese Jewish descent. He is recognized as one of the most influential classical economists, alongside figures such as Thomas Malthus, Adam Smith and James Mill.

Ricardo was born in London as the third surviving child of a successful stockbroker and his wife. He came from a Sephardic Jewish family of Portuguese origin. At 21, he eloped with a Quaker and converted to Unitarianism, causing estrangement from his family. He made his fortune financing government borrowing and later retired to an estate in Gloucestershire. Ricardo served as High Sheriff of Gloucestershire and bought a seat in Parliament as an earnest reformer. He was friends with prominent figures like James Mill, Jeremy Bentham, and Thomas Malthus, engaging in debates over various topics. Ricardo was also a member of The Geological Society, and his youngest sister was an author.

An Inquiry into the Nature and Causes of the Wealth of Nations, usually referred to by its shortened title The Wealth of Nations, is a book by the Scottish economist and moral philosopher Adam Smith; published on 9 March 1776, it offers one of the first accounts of what builds nations' wealth. It has become a fundamental work in classical economics, and been described as "the first formulation of a comprehensive system of political economy". Reflecting upon economics at the beginning of the Industrial Revolution, Smith introduced key concepts such as the division of labour, productivity, free markets and the role prices play in resource allocation.

The book fundamentally shaped the field of economics and provided a theoretical foundation for free market capitalism and economic policies that prevailed in the 19th century. A product of the Scottish Enlightenment and the dawn of the Industrial Revolution, the treatise offered a critical examination of the mercantilist policies of the day and advocated the implementation of free trade and effective tax policies to drive economic progress. It represented a clear paradigm shift from previous economic thought by proposing that self-interest and the forces of supply and demand, rather than regulation, should determine economic activity.
