Monetary policy in the context of "Discretionary policy"

In economics, inflation is an increase in the average price of goods and services in terms of money. This increase is measured using a price index, typically a consumer price index (CPI). 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 CPI 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.

Changes in inflation are widely attributed to fluctuations in real demand for goods and services (also known as demand shocks, including changes in fiscal or monetary policy), changes in available supplies such as during energy crises (also known as supply shocks), or changes in inflation expectations, which may be self-fulfilling. Moderate inflation affects economies in both positive and negative ways. The negative effects would include an increase in the opportunity cost of holding money; uncertainty over future inflation, which may discourage investment and savings; and, if inflation were rapid enough, shortages of goods as consumers begin hoarding out of concern that prices will increase in the future. Positive effects include reducing unemployment due to nominal wage rigidity, allowing the central bank greater freedom in carrying out monetary policy, encouraging loans and investment instead of money hoarding, and avoiding the inefficiencies associated with deflation.

Full employment is an economic situation in which there is no cyclical or deficient-demand unemployment. Full employment does not entail the disappearance of all unemployment, as other kinds of unemployment, namely structural and frictional, may remain. Full employment does not entail 100% employment-to-population ratio. For instance, workers who are "between jobs" for short periods of time as they search for better employment are not counted against full employment, as such unemployment is frictional rather than cyclical. An economy with full employment might also have unemployment or underemployment where part-time workers cannot find jobs appropriate to their skill level, as such unemployment is considered structural rather than cyclical. Full employment marks the point past which expansionary fiscal and/or monetary policy cannot reduce unemployment any further without causing inflation.

Some economists define full employment somewhat differently, as the unemployment rate at which inflation does not continuously increase. Advocacy of avoiding accelerating inflation is based on a theory centered on the concept of the Non-Accelerating Inflation Rate of Unemployment (NAIRU) and those who hold it usually mean NAIRU when speaking of full employment. The NAIRU has also been described by Milton Friedman, among others, as the "natural" rate of unemployment. Such views tend to emphasize sustainability, noting that a government cannot sustain unemployment rates below the NAIRU forever: inflation will continue to grow so long as unemployment lies below the NAIRU.

In economics and political science, fiscal policy is the use of government revenue collection (taxes or tax cuts) and expenditure to influence a country's economy. The use of government revenue expenditures to influence macroeconomic variables developed in reaction to the Great Depression of the 1930s, when the previous laissez-faire approach to economic management became unworkable. Fiscal policy is based on the theories of the British economist John Maynard Keynes, whose Keynesian economics theorised that government changes in the levels of taxation and government spending influence aggregate demand and the level of economic activity. Fiscal and monetary policy are the key strategies used by a country's government and central bank to advance its economic objectives. The combination of these policies enables these authorities to target inflation and to increase employment. In modern economies, inflation is conventionally considered "healthy" in the range of 2%–3%. Additionally, it is designed to try to keep GDP growth at 2%–3% and the unemployment rate near the natural unemployment rate of 4%–5%. This implies that fiscal policy is used to stabilise the economy over the course of the business cycle.

Changes in the level and composition of taxation and government spending can affect macroeconomic variables, including:

The Brunei Darussalam Central Bank (abbrev: BDCB; Malay: Bank Pusat Brunei Darussalam) is the central bank of Brunei. In addition to creating the Brunei currency and managing the nation's monetary policy, its major goals consisted of building and upholding domestic price stability, guaranteeing the stability of the financial system, particularly via the creation of prudential standards and financial regulations, and support the establishment and operation of effective.

The European Central Bank (ECB) is the central component of the Eurosystem and the European System of Central Banks (ESCB) as well as one of seven institutions of the European Union. It is one of the world's most important central banks with a balance sheet total of around 7 trillion.

The ECB Governing Council makes monetary policy for the Eurozone and the European Union, administers the foreign exchange reserves of EU member states, engages in foreign exchange operations, and defines the intermediate monetary objectives and key interest rate of the EU. The ECB Executive Board enforces the policies and decisions of the Governing Council, and may direct the national central banks when doing so. The ECB has the exclusive right to authorise the issuance of euro banknotes. Member states can issue euro coins, but the volume must be approved by the ECB beforehand. The bank also operates the T2 payments system.

The non-accelerating inflation rate of unemployment (NAIRU) is a theoretical level of unemployment below which inflation would be expected to rise. It was first introduced as the NIRU (non-inflationary rate of unemployment) by Franco Modigliani and Lucas Papademos in 1975, as an improvement over the "natural rate of unemployment" concept, which was proposed earlier by Milton Friedman.

In the United States, estimates of the NAIRU ranged between 5 and 6% in the late 20th and early 21st centuries, but have fallen to below 4% since the recovery from the 2008 financial crisis. Monetary policy conducted under the assumption of a NAIRU typically involves allowing just enough unemployment in the economy to prevent inflation rising above a given target figure. Prices are allowed to increase gradually and some unemployment is tolerated.

Milton Friedman (/ˈfriːdmən/ ; July 31, 1912 – November 16, 2006) was an American economist and statistician who received the 1976 Nobel Memorial Prize in Economic Sciences for his research on consumption analysis, monetary history and theory and the complexity of stabilization policy. With George Stigler, Friedman was among the intellectual leaders of the Chicago school of economics, a neoclassical school of economic thought associated with the faculty at the University of Chicago that rejected Keynesianism in favor of monetarism before shifting their focus to new classical macroeconomics in the mid-1970s. Several students, young professors and academics who were recruited or mentored by Friedman at Chicago went on to become leading economists, including Gary Becker (Nobel Prize 1992), Robert Fogel (Nobel Prize 1993), and Robert Lucas Jr. (Nobel Prize 1995).

Friedman's challenges to what he called "naive Keynesian theory" began with his interpretation of consumption, which tracks how consumers spend. He introduced a theory which would later become part of mainstream economics and he was among the first to propagate the theory of consumption smoothing. During the 1960s, he became the main advocate opposing both Marxist and Keynesian government and economic policies, and described his approach (along with mainstream economics) as using "Keynesian language and apparatus" yet rejecting its initial conclusions. He theorized that there existed a natural rate of unemployment and argued that unemployment below this rate would cause inflation to accelerate. He argued that the Phillips curve was in the long run vertical at the "natural rate" and predicted what would come to be known as stagflation. Friedman promoted a macroeconomic viewpoint known as monetarism and argued that a steady, small expansion of the money supply was the preferred policy, as compared to rapid and unexpected changes. His ideas concerning monetary policy, taxation, privatization, and deregulation influenced government policies, especially during the 1980s. His monetary theory influenced the Federal Reserve's monetary policy in response to the 2008 financial crisis.

The economy of governments covers the systems for setting levels of taxation, government budgets, the money supply and interest rates as well as the labour market, national ownership, and many other areas of government interventions into the economy.

Most factors of economic policy can be divided into either fiscal policy, which deals with government actions regarding taxation and spending, or monetary policy, which deals with central banking actions regarding the money supply and interest rates.

In international relations, the liberal international order (LIO), also known as the rules-based order (RBO), consists of a set of global, rule-based, structured relationships based on political liberalism, economic liberalism and liberal internationalism since the late 1940s. More specifically, it entails international cooperation through multilateral institutions (like the United Nations, World Trade Organization and International Monetary Fund) and is constituted by human equality (freedom, rule of law and human rights), open markets, security cooperation, promotion of liberal democracy, and monetary cooperation. The order was established in the aftermath of World War II, led in large part by the United States.

The nature of the LIO, as well as its very existence, has been debated by scholars. The LIO has been credited with expanding free trade, increasing capital mobility, spreading democracy, promoting human rights, and collectively defending the Western world from the Soviet Union. The LIO facilitated unprecedented cooperation among the states of North America, Western Europe and Japan. Over time, the LIO facilitated the spread of economic liberalism to the rest of the world, as well as helped consolidate democracy in formerly fascist or communist countries.
