Stock (variable)
Economics, business, accounting, and related fields often distinguish between quantities that are stocks and those that are flows. These differ in their units of measurement. A ''stock'' is measured at one specific time, and represents a quantity existing at that point in time (say, December 31, 2004), which may have accumulated in the past. A ''flow'' variable is measured over an interval of time. Therefore, a flow would be measured ''per unit of time'' (say a year). Flow is roughly analogous to rate or speed in this sense. For example, U.S. nominal gross domestic product refers to a total number of dollars spent over a time period, such as a year. Therefore, it is a flow variable, and has units of dollars/year. In contrast, the U.S. nominal capital stock is the total value, in dollars, of equipment, buildings, and other real productive assets in the U.S. economy, and has units of dollars. The diagram provides an intuitive illustration of how the ''stock'' of capital currently ...

Stocks And Flows
Stocks are feet and hand restraining devices that were used as a form of corporal punishment and public humiliation. The use of stocks is seen as early as Ancient Greece, where they are described as being in use in Solon's law code. The law describing its use is cited by the orator Lysias: "'He shall have his or her foot confined in the stocks for five days, if the court shall make such addition to the sentence.' The 'stocks' there mentioned, Theomnestus, are what we now call 'confinement in the wood (''Lys''. 10.16). Form and applications The stocks, pillory, and pranger each consist of large wooden boards with hinges; however, the stocks are distinguished by their restraint of the feet. The stocks consist of placing boards around the ankles and wrists, whereas with the pillory, the boards are fixed to a pole and placed around the arms and neck, forcing the punished to stand. Victims may be insulted, kicked, tickled, spat on, or subjected to other inhumane acts. In the Bibl ...

Inventories
Inventory (British English) or stock (American English) is a quantity of the goods and materials that a business holds for the ultimate goal of resale, production or utilisation. Inventory management is a discipline primarily about specifying the shape and placement of stocked goods. It is required at different locations within a facility or within many locations of a supply network to precede the regular and planned course of production and stock of materials. The concept of inventory, stock or work in process (or work in progress) has been extended from manufacturing systems to service businesses and projects, by generalizing the definition to be "all work within the process of production—all work that is or has occurred prior to the completion of production". In the context of a manufacturing production system, inventory refers to all work that has occurred—raw materials, partially finished products, finished products prior to sale and departure from the manufacturing ...

Money Supply
In macroeconomics, money supply (or money stock) refers to the total volume of money held by the public at a particular point in time. There are several ways to define "money", but standard measures usually include currency in circulation (i.e. physical cash) and demand deposits (depositors' easily accessed assets on the books of financial institutions). Money supply data is recorded and published, usually by the national statistical agency or the central bank of the country. Empirical money supply measures are usually named M1, M2, M3, etc., according to how wide a definition of money they embrace. The precise definitions vary from country to country, in part depending on national financial institutional traditions. Even for narrow aggregates like M1, by far the largest part of the money supply consists of deposits in commercial banks, whereas currency (banknotes and coins) issued by central banks only makes up a small part of the total money supply in modern economies. T ...

Nominal GDP
Gross domestic product (GDP) is a monetary measure of the total 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 performance of a country or region. Several national and international economic organizations maintain definitions of GDP, such as the OECD and the International Monetary Fund. GDP is often used as a metric for international comparisons as well as a broad measure of economic progress. It is often considered to be the world's most powerful statistical indicator of national development and progress. The GDP can be divided by the total population to obtain the average GDP per capita. Total GDP can also be broken down into the contribution of each industry or sector of the economy. Nominal GDP is useful when comparing national economies on the international market according to the exchange rate. To compare economies over time inflation can be adjusted b ...

Velocity Of Money
image:M3 Velocity in the US.png, 300px, Similar chart showing the logged velocity (green) of a broader measure of money M3 that covers M2 plus large institutional deposits. The US no longer publishes official M3 measures, so the chart only runs through 2005. Employment again shown in blue, recessions as grey bars. The velocity of money measures the number of times that one unit of currency is used to purchase goods and services within a given time period. In other words, it represents how many times per period money is changing hands, or is circulating to other owners in return for valuable goods and services. The concept relates the size of economic activity to a given money supply. The speed of money exchange is one of the variables that determine inflation. The measure of the velocity of money is usually the ratio of a country's or an economy's nominal gross national product (GNP) to its money supply. If the velocity of money is increasing, then transactions are occurring ...

Debt To GDP Ratio
In economics, the debt-to-GDP ratio is the ratio of a country's accumulation of government debt (measured in units of currency) to its gross domestic product (GDP) (measured in units of currency per year). A low debt-to-GDP ratio indicates that an economy produces goods and services sufficient to pay back debts without incurring further debt. Geopolitical and economic considerations – including interest rates, war, recessions, and other variables – influence the borrowing practices of a nation and the choice to incur further debt. It should not be confused with a deficit-to-GDP ratio, which, for countries running budget deficits, measures a country's annual net fiscal loss in a given year (government budget balance, or the net change in debt per annum) as a percentage share of that country's GDP; for countries running budget surpluses, a ''surplus-to-GDP ratio'' measures a country's annual net fiscal ''gain'' as a share of that country's GDP. Particularly in macroeconomics, va ...

Commensurability (philosophy Of Science)
Commensurability is a concept in the philosophy of science whereby scientific theories are said to be "commensurable" if scientists can discuss the theories using a shared nomenclature that allows direct comparison of them to determine which one is more valid or useful. On the other hand, theories are incommensurable if they are embedded in starkly contrasting conceptual frameworks whose languages do not overlap sufficiently to permit scientists to directly compare the theories or to cite empirical evidence favoring one theory over the other. Discussed by Ludwik Fleck in the 1930s, and popularized by Thomas Kuhn in the 1960s, the problem of incommensurability results in scientists talking past each other, as it were, while comparison of theories is muddled by confusions about terms, contexts and consequences. Introduction of the term In 1962, Thomas Kuhn and Paul Feyerabend both independently introduced the idea of incommensurability to the philosophy of science. In both ...

Labour (economics)
Labour economics seeks to understand the functioning and dynamics of the Market (economics), markets for wage labour. Labour (human activity), Labour is a commodity that is supplied by labourers, usually in exchange for a wage paid by demanding firms. Because these labourers exist as parts of a social, institutional, or political system, labour economics must also account for social, cultural and political variables. 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 demanders of labour services (employers), and attempts to understand the resulting pattern of wages, employment, and income. These patterns exist because each individual in the market is presumed to make rational choices based on the information that they know regarding wage, desire to provide labour, and desire for leisure. Labour markets are normally geographically bounded, but the rise of the internet ...

Inventory Investment
Inventory investment (also private inventory) is a component of gross domestic product (GDP). What is produced in a certain country is naturally also sold eventually, but some of the goods produced in a given year may be sold in a later year rather than in the year they were produced. Conversely, some of the goods sold in a given year might have been produced in an earlier year. The difference between goods produced ( production) and goods sold (sales) in a given year is called inventory investment. The concept can be applied to the economy as a whole or to an individual firm, however this concept is generally applied in macroeconomics (economy as a whole). Unintended unsold stock of goods increases inventory investment. Definition of inventory investment *Inventory investment = production – sales Baumol, William J., and Alan Blinder Blinder, Alan S., ''Macroeconomics: Principles and Policy'', Southwestern College Publ., eleventh edition, 2008. Thus, if production per unit tim ...

Fixed Investment
Fixed investment in economics is the purchase of newly produced physical asset, or, fixed capital. It is measured as a flow variable – that is, as an amount per unit of time. Thus, fixed investment is the sum of physical assets such as machinery, land, buildings, installations, vehicles, or technology. Normally, a company balance sheet will state both the amount of expenditure on fixed assets during the quarter or year, and the total value of the stock of fixed assets owned. Fixed investment contrasts with investments in labour, ongoing operating expenses, materials or financial assets. Financial assets may also be held for a fixed term (for example, bonds) but they are not usually called "fixed investment" because they do not involve the purchase of physical fixed assets. The more usual term for such financial investments is "fixed-term investments". Bank deposits committed for a fixed term such as one or two years in a savings account are similarly called "fixed-term deposi ...

Saving
Saving is income not spent, or deferred Consumption (economics), consumption. In economics, a broader definition is any income not used for immediate consumption. Saving also involves reducing expenditures, such as recurring Cost, costs. Methods of saving include putting money in, for example, a savings account, a pension, pension account, an investment fund, or kept as cash. In terms of personal finance, saving generally specifies low-risk preservation of money, as in a deposit account, versus investment, wherein risk is a lot higher. Saving does not automatically include interest. ''Saving'' differs from ''savings''. The former refers to the act of not consuming one's assets, whereas the latter refers to either multiple opportunities to reduce costs; or one's assets in the form of cash. Saving refers to an activity occurring over time, a stock and flow, flow variable, whereas savings refers to something that exists at any one time, a stock and flow, stock variable. This disti ...

Expenditure
An expense is an item requiring an outflow of money, or any form of fortune in general, to another person or group as payment for an item, service, or other category of costs. For a tenant, rent is an expense. For students or parents, tuition is an expense. Buying food, clothing, furniture, or an automobile is often referred to as an expense. An expense is a cost that is "paid" or " remitted", usually in exchange for something of value. Something that seems to cost a great deal is "expensive". Something that seems to cost little is "inexpensive". "Expenses of the table" are expenses for dining, refreshments, a feast, etc. In accounting, ''expense'' is any specific outflow of cash or other valuable assets from a person or company to another person or company. This outflow is generally one side of a trade for products or services that have equal or better current or future value to the buyer than to the seller. Technically, an expense is an event in which a proprietary stake is di ...
