In Money and the Mechanism of Exchange (1875), William Stanley analyzed Jevon`s money based on four functions: a medium of exchange, a common value (or unit of account), a value standard (or standard for deferred payments), and a value memory. Until 1919, the four functions of Jevons money were grouped in the verse: modern monetary theory distinguishes between different ways of measuring the money stock or money supply, which are reflected in different types of monetary aggregates, using a categorization system focused on the liquidity of the financial instrument used as money. The most commonly used monetary aggregates (or types of money) are conventionally called M1, M2 and M3. These aggregated categories are progressively larger: M1 is money (coins and notes) plus demand deposits (e.g.B. current accounts; M2 is M1 plus savings accounts and term deposits under $100,000; M3 is M2, plus larger term deposits and similar institutional accounts. M1 covers only the most liquid financial instruments and M3 relatively illiquid. The exact definition of M1, M2, etc., may vary from country to country. Historically, money is an emerging market phenomenon that establishes a market currency, but almost all contemporary monetary systems are based on Fiat money. [4] Fiat money, like any cheque or promissier note, has no value of use as physical goods. [Citation required] It indicates its value by declaring it to be legal tender by a government; In other words, it must be accepted as a means of payment within the country`s borders, for “all debts, public and private”.
[6] [best source needed] Fake money can cause good money to lose value. The task of keeping inflation low and stable is usually entrusted to the monetary authorities. Generally speaking, these monetary authorities are the national banks that control monetary policy through the setting of interest rates, open market operations and the setting of reserve requirements for banks. [38] Fiat money or Fiat money is money whose value is not derived from intrinsic value or guarantees that it can be converted into a valuable good (such as gold). . . .
