Economic Stability
Economic stability is the absence of excessive fluctuations in the macroeconomy. An economy with fairly constant output growth and low and stable inflation would be considered economically stable. An economy with frequent large recessions, a pronounced business cycle, very high or variable inflation, or frequent financial crises would be considered economically unstable. Measures Real macroeconomic output can be decomposed into a trend and a cyclical part, where the variance of the cyclical series derived from the filtering technique (e.g., the band-pass filter, or the most commonly used Hodrick–Prescott filter) serves as the primary measure of departure from economic stability. A simple method of decomposition involves regressing real output on the variable "time", or on a polynomial in the time variable, and labeling the predicted levels of output as the trend and the residuals as the cyclical portion. Another approach is to model real output as difference stationary wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macroeconomy
Macroeconomics is a branch of economics that deals with the performance, structure, behavior, and decision-making of an economy as a whole. This includes regional, national, and global economies. Macroeconomists study topics such as output (economics), output/Gross domestic product, GDP (gross domestic product) and national income, unemployment (including Unemployment#Measurement, unemployment rates), price index, price indices and inflation, Consumption (economics), consumption, saving, investment (macroeconomics), investment, Energy economics, energy, international trade, and international finance. Macroeconomics and microeconomics are the two most general fields in economics. The focus of macroeconomics is often on a country (or larger entities like the whole world) and how its markets interact to produce large-scale phenomena that economists refer to as aggregate variables. In microeconomics the focus of analysis is often a single market, such as whether changes in supply or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Financial Stability
Financial stability is the absence of system-wide episodes in which a financial crisis occurs and is characterised as an economy with Volatility (finance), low volatility. It also involves financial systems' stress-resilience being able to cope with both good and bad times. Financial stability is the aim of most governments and central banks. The aim is not to prevent crisis or stop bad financial decisions. It is there to hold the economy together and keep the system running smoothly while such events are happening. The foundation of financial stability is the creation of a system that is able to absorb all of the positive and negative events that happen to the economy at any given time. It has nothing to do with preventing individuals or businesses from failing, losing money, or succeeding. It is merely assisting in the creation of conditions for the system's continued efficient operation in the face of such occurrences. The economy is one that is constantly changing and expandi ...

Fiscal Policy
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%. Add ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monetary Policy
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 (normally interpreted as a low and stable rate of inflation). 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 tools of monetary policy vary from central bank to central bank, depending on the country's stage of development, inst ...

Aggregate Supply
In economics, aggregate supply (AS) or domestic final supply (DFS) is the total supply of goods and services that firms in a national economy plan on selling during a specific time period. It is the total amount of goods and services that firms are willing and able to sell at a given price level in an economy. Together with aggregate demand it serves as one of two components for the AD–AS model. Analysis There are two main reasons why the amount of aggregate output supplied might rise as price level ''P'' rises, i.e., why the ''AS'' curve is upward sloping: * The short-run ''AS'' curve is drawn given some nominal variables such as the nominal wage rate, which is assumed fixed in the ''short run''. Thus, a higher price level ''P'' implies a lower real wage rate and thus an incentive to produce more output. In the neoclassical ''long run'', on the other hand, the nominal wage rate varies with economic conditions. (High unemployment leads to falling nominal wages which restor ...

Real Business Cycle
Real business-cycle theory (RBC theory) is a class of new classical macroeconomics models in which business-cycle fluctuations are accounted for by real, in contrast to nominal, shocks. RBC theory sees business cycle fluctuations as the efficient response to exogenous changes in the real economic environment. That is, the level of national output necessarily maximizes ''expected'' utility. In RBC models, business cycles are described as "real" because they reflect optimal adjustments by economic agents rather than failures of markets to clear. As a result, RBC theory suggests that governments should concentrate on long-term structural change rather than intervention through discretionary fiscal or monetary policy. These ideas are strongly associated with freshwater economics within the neoclassical economics tradition, particularly the Chicago School of Economics.

Aggregate Demand
In economics, aggregate demand (AD) or domestic final demand (DFD) is the total demand for final goods and services in an economy at a given time. It is often called effective demand, though at other times this term is distinguished. This is the demand for the gross domestic product of a country. It specifies the amount of goods and services that will be purchased at all possible price levels. Consumer spending, investment, corporate and government expenditure, and net exports make up the aggregate demand. The aggregate demand curve is plotted with real output on the horizontal axis and the price level on the vertical axis. While it is theorized to be downward sloping, the Sonnenschein–Mantel–Debreu results show that the slope of the curve cannot be mathematically derived from assumptions about individual rational behavior. Instead, the downward sloping aggregate demand curve is derived with the help of three macroeconomic assumptions about the functioning of markets: Pi ...

Keynesian Economics
Keynesian economics ( ; sometimes Keynesianism, named after British economist John Maynard Keynes) are the various macroeconomics, macroeconomic theories and Economic model, models of how aggregate demand (total spending in the economy) strongly influences Output (economics), economic output and inflation. In the Keynesian view, aggregate demand does not necessarily equal the aggregate supply, productive capacity of the economy. It is influenced by a host of factors that sometimes behave erratically and impact production, employment, and inflation. Keynesian economists generally argue that aggregate demand is volatile and unstable and that, consequently, a market economy often experiences inefficient macroeconomic outcomes, including economic recession, recessions when demand is too low and inflation when demand is too high. Further, they argue that these economic fluctuations can be mitigated by economic policy responses coordinated between a government and their central bank. ...

John Maynard Keynes
John Maynard Keynes, 1st Baron Keynes ( ; 5 June 1883 – 21 April 1946), was an English economist and philosopher whose ideas fundamentally changed the theory and practice of macroeconomics and the economic policies of governments. Originally trained in mathematics, he built on and greatly refined earlier work on the causes of business cycles. One of the most influential economists of the 20th century, he produced writings that are the basis for the schools of economic thought, school of thought known as Keynesian economics, and its various offshoots. His ideas, reformulated as New Keynesianism, are fundamental to mainstream economics, mainstream macroeconomics. He is known as the "father of macroeconomics". During the Great Depression of the 1930s, Keynes spearheaded Keynesian Revolution, a revolution in economic thinking, challenging the ideas of neoclassical economics that held that free markets would, in the short to medium term, automatically provide full employment, as ...

Great Depression
The Great Depression was a severe global economic downturn from 1929 to 1939. The period was characterized by high rates of unemployment and poverty, drastic reductions in industrial production and international trade, and widespread bank and business failures around the world. The economic contagion began in 1929 in the United States, the largest economy in the world, with the devastating Wall Street stock market crash of October 1929 often considered the beginning of the Depression. Among the countries with the most unemployed were the U.S., the United Kingdom, and Weimar Republic, Germany. The Depression was preceded by a period of industrial growth and social development known as the "Roaring Twenties". Much of the profit generated by the boom was invested in speculation, such as on the stock market, contributing to growing Wealth inequality in the United States, wealth inequality. Banks were subject to laissez-faire, minimal regulation, resulting in loose lending and wides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milton Friedman
Milton Friedman (; 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, Robert Fogel, and Robert Lucas Jr. 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 w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Money Supply
In macroeconomics, money supply (or money stock) 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 (i.e. physical cash) and demand deposits (depositors' easily accessed assets on the books of financial institutions). 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. Even for narrow aggregates like M1, by far the largest part of the money supply consists of deposits in commercial banks, whereas currency (banknotes and coins) issued by central banks only makes up a small part of the total money supply in modern economies.
