Macroeconomics is a branch of economics that deals with the performance, structure, behavior, and decision-making of an economy as a whole. This includes national, regional, and global economies. Macroeconomists study topics such as output/GDP and national income, unemployment, price indices and inflation, consumption, saving, investment, energy, international trade, and international finance.
In economics, inflation is a general increase in the prices of goods and services in an economy. This is usually measured using the 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. As prices faced by households do not all increase at the same rate, the consumer price index (CPI) is often used for this purpose.
Monetarism is a school of thought in monetary economics that emphasizes the role of policy-makers in controlling the amount of money in circulation. It gained prominence in the 1970s, but was mostly abandoned as a direct guidance to monetary policy during the following decade because of the rise of inflation targeting through movements of the official interest rate.
Fischer Sheffey Black was an American economist, best known as one of the authors of the Black–Scholes equation.
In macroeconomics, money supply refers to the total volume of money 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 and demand deposits. Money supply data is recorded and published, usually by the national statistical agency or the central bank of the country. Empirical money supply measures are usually named M1, M2, M3, etc., according to how wide a definition of money they embrace. The precise definitions vary from country to country, in part depending on national financial institutional traditions.
Monetary economics is the branch of economics that studies the different theories of money: it provides a framework for analyzing money and considers its functions, 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.
Monetary policy is the policy adopted by the monetary authority of a nation to affect monetary and other financial conditions to accomplish broader objectives like high employment and price stability. Further purposes of a monetary policy may be to contribute to economic stability or to maintain predictable exchange rates with other currencies. Today most central banks in developed countries conduct their monetary policy within an inflation targeting framework, whereas the monetary policies of most developing countries' central banks target some kind of a fixed exchange rate system. A third monetary policy strategy, targeting the money supply, was widely followed during the 1980s, but has diminished in popularity since then, though it is still the official strategy in a number of emerging economies.
The quantity theory of money is a hypothesis within monetary economics which states that the general price level of goods and services is directly proportional to the amount of money in circulation, and that the causality runs from money to prices. This implies that the theory potentially explains inflation. It originated in the 16th century and has been proclaimed the oldest surviving theory in economics.
Money creation, or money issuance, is the process by which the money supply of a country, or an economic or monetary region, is increased. In most modern economies, money is created by both central banks and commercial banks. Money issued by central banks is a liability, typically called reserve deposits, and is only available for use by central bank account holders, which are generally large commercial banks and foreign central banks. Central banks can increase the quantity of reserve deposits directly, by making loans to account holders, purchasing assets from account holders, or by recording an asset, such as a deferred asset, and directly increasing liabilities. However, the majority of the money supply used by the public for conducting transactions is created by the commercial banking system in the form of commercial bank deposits. Bank loans issued by commercial banks expand the quantity of bank deposits.
The Austrian business cycle theory (ABCT) is an economic theory developed by the Austrian School of economics seeking to explain how business cycles occur. The theory views business cycles as the consequence of excessive growth in bank credit due to artificially low interest rates set by a central bank or fractional reserve banks. The Austrian business cycle theory originated in the work of Austrian School economists Ludwig von Mises and Friedrich Hayek. Hayek won the Nobel Prize in Economics in 1974 in part for his work on this theory.
In economics, an optimum currency area (OCA) or optimal currency region (OCR) is a geographical region in which it would maximize economic efficiency to have the entire region share a single currency.
David Ernest William Laidler is an English/Canadian economist who has been one of the foremost scholars of monetarism. He published major economics journal articles on the topic in the late 1960s and early 1970s. His book, The Demand for Money, was published in four editions from 1969 through 1993, initially setting forth the stability of the relationship between income and the demand for money and later taking into consideration the effects of legal, technological, and institutional changes on the demand for money. The book has been translated into French, Spanish, Italian, Japanese, and Chinese.
Karl Brunner was a Swiss economist.
Monetary inflation is a sustained increase in the money supply of a country. Depending on many factors, especially public expectations, the fundamental state and development of the economy, and the transmission mechanism, it is likely to result in price inflation, which is usually just called "inflation", which is a rise in the general level of prices of goods and services.
The following is a list of works by the prominent American economist Milton Friedman.
A Monetary History of the United States, 1867–1960 is a book written in 1963 by Nobel Prize–winning economist Milton Friedman and Anna J. Schwartz. It uses historical time series and economic analysis to argue the then-novel proposition that changes in the money supply profoundly influenced the U.S. economy, especially the behavior of economic fluctuations. The implication they draw is that changes in the money supply had unintended adverse effects, and that sound monetary policy is necessary for economic stability. Orthodox economic historians see it as one of the most influential economics books of the century. The chapter dealing with the causes of the Great Depression was published as a stand-alone book titled The Great Contraction, 1929–1933.
Neil Wallace is an American economist and professor of economics at Penn State University. He is considered one of the main proponents of new classical macroeconomics in the field of economics.
Market monetarism is a school of macroeconomics that advocates that central banks use a nominal income target instead of inflation, unemployment, or other measures of economic activity, including in times of demand shocks such as the bursting of the 2000s United States housing bubble and in the 2007–2008 financial crisis. In contrast to traditional monetarists, market monetarists do not believe that money supply 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.
David I. Meiselman was an American economist. Among his contributions to the field of economics are his work on the term structure of interest rates, the foundation today of the implementation of monetary policy by major central banks, and his work with Milton Friedman on the impact of monetary policy on the performance of the economy and inflation.
Michael David Bordo is a Canadian and American economist, currently Board of Governors Professor of Economics and Distinguished Professor of Economics at Rutgers University. He is a research associate at the National Bureau of Economic Research as well as a Distinguished Visiting Fellow at the Hoover Institution at Stanford University. He is the third most influential economic historian worldwide according to the RePEc/IDEAS rankings. He was a student of Milton Friedman and has co-authored numerous books and articles with Anna Schwartz.
