Gross domestic product (GDP) is a monetary measure of the market value of all the final goods and services produced and rendered in a specific time period by a country or countries. GDP is often used to measure the economic health of a country or region. Several national and international economic organizations maintain definitions of GDP, such as the OECD and the International Monetary Fund.
Growth accounting is a procedure used in economics to measure the contribution of different factors to economic growth and to indirectly compute the rate of technological progress, measured as a residual, in an economy. Growth accounting decomposes the growth rate of an economy's total output into that which is due to increases in the contributing amount of the factors used—usually the increase in the amount of capital and labor—and that which cannot be accounted for by observable changes in factor utilization. The unexplained part of growth in GDP is then taken to represent increases in productivity or a measure of broadly defined technological progress.
This aims to be a complete article list of economics topics:
In accounting, fixed capital is any kind of real, physical asset that is used repeatedly in the production of a product. In economics, fixed capital is a type of capital good that as a real, physical asset is used as a means of production which is durable or isn't fully consumed in a single time period. It contrasts with circulating capital such as raw materials, operating expenses etc.
In economics, a production function gives the technological relation between quantities of physical inputs and quantities of output of goods. The production function is one of the key concepts of mainstream neoclassical theories, used to define marginal product and to distinguish allocative efficiency, a key focus of economics. One important purpose of the production function is to address allocative efficiency in the use of factor inputs in production and the resulting distribution of income to those factors, while abstracting away from the technological problems of achieving technical efficiency, as an engineer or professional manager might understand it.
Productivity is the efficiency of production of goods or services expressed by some measure. Measurements of productivity are often expressed as a ratio of an aggregate output to a single input or an aggregate input used in a production process, i.e. output per unit of input, typically over a specific period of time. The most common example is the (aggregate) labour productivity measure, one example of which is GDP per worker. There are many different definitions of productivity and the choice among them depends on the purpose of the productivity measurement and data availability. The key source of difference between various productivity measures is also usually related to how the outputs and the inputs are aggregated to obtain such a ratio-type measure of productivity.
The organic composition of capital (OCC) is a concept created by Karl Marx in his theory of capitalism, which was simultaneously his critique of the political economy of his time. It is derived from his more basic concepts of 'value composition of capital' and 'technical composition of capital'. Marx defines the organic composition of capital as "the value-composition of capital, in so far as it is determined by its technical composition and mirrors the changes of the latter". The 'technical composition of capital' measures the relation between the elements of constant capital and variable capital. It is 'technical' because no valuation is here involved. In contrast, the 'value composition of capital' is the ratio between the value of the elements of constant capital involved in production and the value of the labor. Marx found that the special concept of 'organic composition of capital' was sometimes useful in analysis, since it assumes that the relative values of all the elements of capital are constant.
Value added is a term in financial economics for calculating the difference between market value of a product or service, and the sum value of its constituents. It is relatively expressed to the supply-demand curve for specific units of sale. It represents a market equilibrium view of production economics and financial analysis. Value added is distinguished from the accounting term added value which measures only the financial profits earned upon transformational processes for specific items of sale that are available on the market.
In economics, total-factor productivity (TFP), also called multi-factor productivity, is usually measured as the ratio of aggregate output to aggregate inputs. Under some simplifying assumptions about the production technology, growth in TFP becomes the portion of growth in output not explained by growth in traditionally measured inputs of labour and capital used in production. TFP is calculated by dividing output by the weighted geometric average of labour and capital input, with the standard weighting of 0.7 for labour and 0.3 for capital. Total factor productivity is a measure of productive efficiency in that it measures how much output can be produced from a certain amount of inputs. It accounts for part of the differences in cross-country per-capita income. For relatively small percentage changes, the rate of TFP growth can be estimated by subtracting growth rates of labor and capital inputs from the growth rate of output.
The Solow–Swan model or exogenous growth model is an economic model of long-run economic growth. It attempts to explain long-run economic growth by looking at capital accumulation, labor or population growth, and increases in productivity largely driven by technological progress. At its core, it is an aggregate production function, often specified to be of Cobb–Douglas type, which enables the model "to make contact with microeconomics". The model was developed independently by Robert Solow and Trevor Swan in 1956, and superseded the Keynesian Harrod–Domar model.
The value product (VP) is an economic concept formulated by Karl Marx in his critique of political economy during the 1860s, and used in Marxian social accounting theory for capitalist economies. Its annual monetary value is approximately equal to the netted sum of six flows of income generated by production:
Prices of production is a concept in Karl Marx's critique of political economy, defined as "cost-price + average profit". A production price can be thought of as a type of supply price for products; it refers to the price levels at which newly produced goods and services would have to be sold by the producers, in order to reach a normal, average profit rate on the capital invested to produce the products.
Operating surplus is an accounting concept used in national accounts statistics and in corporate and government accounts. It is the balancing item of the Generation of Income Account in the UNSNA. It may be used in macro-economics as a proxy for total pre-tax profit income, although entrepreneurial income may provide a better measure of business profits. According to the 2008 SNA, it is the measure of the surplus accruing from production before deducting property income, e.g., land rent and interest.
Domar aggregation is an approach to aggregating growth measures associated with industries to make larger sector or national aggregate growth rates. The issue comes up in the context of national accounts and multifactor productivity (MFP) statistics.
Differential ground rent and absolute ground rent are concepts used by Karl Marx in the third volume of Das Kapital to explain how the capitalist mode of production would operate in agricultural production, under the condition where most agricultural land was owned by a social class of land-owners who could obtain rent income from farm production. Rent as an economic category is regarded by Marx as one form of surplus value just like net interest income, net production taxes and industrial profits. Marx's main texts on rent theory can be found in the second (edited) volume of Theories of Surplus Value and in Part 6 of Capital, Volume III. Anwar M. Shaikh states that "These remarkably rich and insightful sections of his work are seldom mentioned in the Marxian literature, and are even less understood."
Production is the process of combining various inputs, both material and immaterial 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.
Productivity in economics is usually measured as the ratio of what is produced to what is used in producing it. Productivity is closely related to the measure of production efficiency. A productivity model is a measurement method which is used in practice for measuring productivity. A productivity model must be able to compute Output / Input when there are many different outputs and inputs.
Anwar M. Shaikh is a Pakistani American heterodox economist in the tradition of classical political economy and Marxian economics.
In Marxian economics, surplus value is the difference between the amount raised through a sale of a product and the amount it cost to manufacture it: i.e. the amount raised through sale of the product minus the cost of the materials, plant and labour power. The concept originated in Ricardian socialism, with the term "surplus value" itself being coined by William Thompson in 1824; however, it was not consistently distinguished from the related concepts of surplus labor and surplus product. The concept was subsequently developed and popularized by Karl Marx. Marx's formulation is the standard sense and the primary basis for further developments, though how much of Marx's concept is original and distinct from the Ricardian concept is disputed. Marx's term is the German word "Mehrwert", which simply means value added, and is cognate to English "more worth".
