Macroeconomics is a branch of economics dealing with the performance, structure, behavior, and decision-making of an economy as a whole. This includes regional, national, and global economies. Macroeconomists study aggregated indicators such as GDP, unemployment rates, national income, price indices, and the interrelations among the different sectors of the economy to better understand how the whole economy functions. They also develop models that explain the relationship between such factors as national income, output, consumption, unemployment, inflation, saving, investment, international trade, and international finance.
In economics, inflation is a sustained increase in the general price level of goods and services in an economy over a period of time. When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation reflects a reduction in the purchasing power per unit of money – a loss of real value in the medium of exchange and unit of account within the economy. The measure of inflation is the inflation rate, the annualized percentage change in a general price index, usually the consumer price index, over time. The opposite of inflation is deflation.
The IS–LM model, or Hicks–Hansen model, is a macroeconomic tool that shows the relationship between interest rates (ordinate) and assets market. The intersection of the "investment–saving" (IS) and "liquidity preference–money supply" (LM) curves models "general equilibrium" where supposed simultaneous equilibria occur in both the goods and the asset markets. Yet two equivalent interpretations are possible: first, the IS–LM model explains changes in national income when price level is fixed short-run; second, the IS–LM model shows why an aggregate demand curve can shift. Hence, this tool is sometimes used not only to analyse economic fluctuations but also to suggest potential levels for appropriate stabilisation policies.
New Keynesian economics is a school of contemporary macroeconomics that strives to provide microeconomic foundations for Keynesian economics. It developed partly as a response to criticisms of Keynesian macroeconomics by adherents of new classical macroeconomics.
The Phillips curve is a single-equation econometric model, named after William Phillips, describing a historical inverse relationship between rates of unemployment and corresponding rates of rises in wages that result within an economy. Stated simply, decreased unemployment, in an economy will correlate with higher rates of wage rises. Phillips did not himself state there was any relationship between employment and inflation; this notion was a trivial deduction from his statistical findings. Samuelson and Solow made the connection explicit and subsequently Milton Friedman and Edmund Phelps put the theoretical structure in place. In so doing, Friedman was to successfully predict the imminent collapse of Phillips' a-theoretic correlation.
Monetary policy is the process by which the monetary authority of a country, typically the central bank or currency board, controls either the cost of very short-term borrowing or the money supply, often targeting an inflation rate or interest rate to ensure price stability and general trust in the currency.
The Federal Open Market Committee (FOMC), a committee within the Federal Reserve System, is charged under United States law with overseeing the nation's open market operations. This Federal Reserve committee makes key decisions about interest rates and the growth of the United States money supply.
Neutrality of money is the idea that a change in the stock of money affects only nominal variables in the economy such as prices, wages, and exchange rates, with no effect on real variables, like employment, real GDP, and real consumption. Neutrality of money is an important idea in classical economics and is related to the classical dichotomy. It implies that the central bank does not affect the real economy by creating money. Instead, any increase in the supply of money would be offset by a proportional rise in prices and wages. This assumption underlies some mainstream macroeconomic models. Others like monetarism view money as being neutral only in the long-run.
Inflation targeting is a monetary policy regime in which a central bank has an explicit target inflation rate for the medium term and announces this inflation target to the public. The assumption is that the best that monetary policy can do to support long-term growth of the economy is to maintain price stability. The central bank uses interest rates, its main short-term monetary instrument.
In macroeconomics, a monetary conditions index (MCI) is an index number calculated from a linear combination of a small number of economy-wide financial variables deemed relevant for monetary policy. These variables always include a short-run interest rate and an exchange rate.
Quantitative easing (QE), also known as large-scale asset purchases, is a monetary policy whereby a central bank buys predetermined amounts of government bonds or other financial assets in order to inject money directly into the economy. An unconventional form of monetary policy, it is usually used when inflation is very low or negative, and standard expansionary monetary policy has become ineffective. A central bank implements quantitative easing by buying specified amounts of financial assets from commercial banks and other financial institutions, thus raising the prices of those financial assets and lowering their yield, while simultaneously lowering short term interest rates which increases the money supply. This differs from the more usual policy of buying or selling short-term government bonds to keep interbank interest rates at a specified target value.
In monetary economics, the demand for money is the desired holding of financial assets in the form of money: that is, cash or bank deposits rather than investments. It can refer to the demand for money narrowly defined as M1, or for money in the broader sense of M2 or M3.
James Brian Bullard is the chief executive officer and 12th president of the Federal Reserve Bank of St. Louis, positions he has held since 2008. He is currently serving a term that began on March 1, 2016. In 2014, he was named the 7th most influential economist in the world.
In economics, stimulus refers to attempts to use monetary or fiscal policy to stimulate the economy. Stimulus can also refer to monetary policies like lowering interest rates and quantitative easing.
The credit channel mechanism of monetary policy describes the theory that a central bank's policy changes affect the amount of credit that banks issue to firms and consumers for purchases, which in turn affects the real economy.
The Sukhamoy Chakravarty Committee was formed in December 1982 under the chairmanship of Prof. Sukhamoy Chakroborty to assess the functioning of the Indian Monetary system. Its goal was to improve monetary regulation, a feat that was hoped would enable price stability. The committee, which submitted its report in April 1985, believed that price stability was essential for promoting growth and achieving other social objectives.
Market monetarism is a school of macroeconomic thought that advocates that central banks target the level of nominal income instead of inflation, unemployment, or other measures of economic activity, including in times of shocks such as the bursting of the real estate bubble in 2006, and in the financial crisis that followed. In contrast to traditional monetarists, market monetarists do not believe monetary aggregates or commodity prices such as gold are the optimal guide to intervention. Market monetarists also reject the New Keynesian focus on interest rates as the primary instrument of monetary policy. Market monetarists prefer a nominal income target due to their twin beliefs that rational expectations are crucial to policy, and that markets react instantly to changes in their expectations about future policy, without the "long and variable lags" postulated by Milton Friedman.
The interest rate channel is a mechanism of monetary policy, whereby a policy-induced change in the short-term nominal interest rate by the central bank affects the price level, and subsequently output and employment.
