Stock And Flow
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stocks And Flows
Stocks are feet 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 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 Bible, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inventories
Inventory (American English) or stock (British English) refers to 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 system. ...

Money Supply
In macroeconomics, the money supply (or money stock) refers to the total volume of currency 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). The central bank of a country may use a definition of what constitutes legal tender for its purposes. Money supply data is recorded and published, usually by a government agency or the central bank of the country. Public and private sector analysts monitor changes in the money supply because of the belief that such changes affect the price levels of securities, inflation, the exchange rates, and the business cycle. The relationship between money and prices has historically been associated with the quantity theory of money. There is some empirical evidence of a direct relationship between the growth of the money su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nominal GDP
Gross domestic product (GDP) is a money, monetary Measurement in economics, measure of the market value of all the final goods and services produced and sold (not resold) in a specific time period by countries. Due to its complex and subjective nature this measure is often revised before being considered a reliable indicator. List of countries by GDP (nominal) per capita, GDP (nominal) per capita does not, however, reflect differences in the cost of living and the inflation, inflation rates of the countries; therefore, using a basis of List of countries by GDP (PPP) per capita, GDP per capita at purchasing power parity (PPP) may be more useful when comparing standard of living, living standards between nations, while nominal GDP is more useful comparing national economies on the international market. Total GDP can also be broken down into the contribution of each industry or sector of the economy. The ratio of GDP to the total population of the region is the GDP per capita, p ...

Velocity Of Money

The US no longer publishes official M3 measures, so the chart only runs through 2005. The velocity of money measures the number of times that the average unit of currency is used to purchase goods and services within a given time period. The concept relates the size of economic activity to a given money supply, and 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 the gross national product (GNP) to a country's money supply. If the velocity of money is increasing, then transactions are occurring between individuals more frequently. The velocity of money changes over time and is influenced by a variety of factors. Illustration If, for example, in a very small economy, a farmer and a mechanic, with just $50 between them, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Debt To GDP Ratio
In economics, the debt-to-GDP ratio is the ratio between a country's government debt (measured in units of currency) and its gross domestic product (GDP) (measured in units of currency per year). While it is a "ratio", it is technically measured in units of year, and can be interpreted as the number of years a country needs to pay off its entire debt, if all its GDP is devoted towards it. 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 ( total expenditures minus total revenue, or the net change in debt per annum) as a percentage share of tha ...

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 case ...

Inventory Investment
Inventory investment 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 time exceeds sales per unit ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fixed Investment
Fixed investment in economics is the purchasing of newly produced fixed capital. It is measured as a flow variable – that is, as an amount per unit of time. Thus, fixed investment is the accumulation 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 deposits". Sta ...

Saving
Saving is income not spent, or deferred consumption. Methods of saving include putting money aside in, for example, a deposit account, a pension account, an investment fund, or as cash. Saving also involves reducing expenditures, such as recurring costs. 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; in economics more broadly, it refers to any income not used for immediate consumption. 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 flow variable, whereas savings refers to something that exists at any one time, a stock variable. This distinction is often misunderstood, and even professional economists and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
