Modern monetary theoryModern monetary theory or modern money theory (MMT) is a heterodox macroeconomic theory that describes currency as a public monopoly and unemployment as evidence that a currency monopolist is overly restricting the supply of the financial assets needed to pay taxes and satisfy savings desires. According to MMT, governments do not need to worry about accumulating debt since they can create new money by using fiscal policy in order to pay interest.
MetallismMetallism is the economic principle that the value of money derives from the purchasing power of the commodity upon which it is based. The currency in a metallist monetary system may be made from the commodity itself (commodity money) or it may use tokens (such as national banknotes) redeemable in that commodity. Georg Friedrich Knapp (1842–1926) coined the term "metallism" to describe monetary systems using coin minted in silver, gold or other metals.
Fiat moneyFiat money is a type of currency that is not backed by a commodity, such as gold or silver. It is typically designated by the issuing government to be legal tender. Throughout history, fiat money was quite rare until the 20th century, but there were some situations where banks or governments stopped honoring redeemability of demand notes or credit notes, usually temporarily. In modern times, fiat money is generally authorized by government regulation. Fiat money generally does not have intrinsic value and does not have use value.
History of moneyThe history of money is the development over time of systems for the exchange, storage, and measurement of wealth. Money is a means of fulfilling these functions indirectly and in general rather than directly, as with barter. Money may take a physical form as in coins and notes, or may exist as a written or electronic account. It may have intrinsic value (commodity money), or be legally exchangeable for something with intrinsic value (representative money), or only have nominal value (fiat money).
Monetary economicsMonetary economics is the branch of economics that studies the different theories of money: it provides a framework for analyzing money and considers its functions (such as medium of exchange, store of value, and unit of account), and it considers how money can gain acceptance purely because of its convenience as a public good. The discipline has historically prefigured, and remains integrally linked to, macroeconomics. This branch also examines the effects of monetary systems, including regulation of money and associated financial institutions and international aspects.
Money creationMoney creation, or money issuance, is the process by which the money supply of a country, or of an economic or monetary region, is increased. In most modern economies, money creation is controlled by the central banks. Money issued by central banks is termed base money. Central banks can increase the quantity of base money directly, by engaging in open market operations. However, the majority of the money supply is created by the commercial banking system in the form of bank deposits.
MoneyMoney is any item or verifiable record that is generally accepted as payment for goods and services and repayment of debts, such as taxes, in a particular country or socio-economic context. The primary functions which distinguish money are as a medium of exchange, a unit of account, a store of value and sometimes, a standard of deferred payment. Money was historically an emergent market phenomenon that possessed intrinsic value as a commodity; nearly all contemporary money systems are based on unbacked fiat money without use value.
Money supplyIn 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.
Commodity moneyCommodity money is money whose value comes from a commodity of which it is made. Commodity money consists of objects having value or use in themselves (intrinsic value) as well as their value in buying goods. This is in contrast to representative money, which has no intrinsic value but represents something of value such as gold or silver, in which it can be exchanged, and fiat money, which derives its value from having been established as money by government regulation.
Deficit spendingWithin the budgetary process, deficit spending is the amount by which spending exceeds revenue over a particular period of time, also called simply deficit, or budget deficit; the opposite of budget surplus. The term may be applied to the budget of a government, private company, or individual. Government deficit spending was first identified as a necessary economic tool by John Maynard Keynes in the wake of the Great Depression. It is a central point of controversy in economics, as discussed below.
