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.
Quantitative easingQuantitative easing (QE) is a monetary policy action where a central bank purchases predetermined amounts of government bonds or other financial assets in order to stimulate economic activity. Quantitative easing is a novel form of monetary policy that came into wide application after the financial crisis of 20072008. It is used to mitigate an economic recession when inflation is very low or negative, making standard monetary policy ineffective.
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.
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.
InflationIn economics, inflation is an increase in the general price level of goods and services in an economy. When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation corresponds to a reduction in the purchasing power of money. The opposite of inflation is deflation, a decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index.
