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. Measuring stability 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 st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macroeconomy
Macroeconomics (from the Greek prefix ''makro-'' meaning "large" + ''economics'') is a branch of economics dealing with performance, structure, behavior, and decision-making of an economy as a whole. For example, using interest rates, taxes, and government spending to regulate an economy's growth and stability. This includes regional, national, and global economies. According to a 2018 assessment by economists Emi Nakamura and Jón Steinsson, economic "evidence regarding the consequences of different macroeconomic policies is still highly imperfect and open to serious criticism." Macroeconomists study topics such as GDP (Gross Domestic Product), unemployment (including unemployment rates), national income, price indices, output, consumption, inflation, saving, investment, energy, international trade, and international finance. Macroeconomics and microeconomics are the two most general fields in economics. The United Nations Sustainable Development Goal 17 has a target to enhan ...

Monetarist
Monetarism is a school of thought in monetary economics that emphasizes the role of governments in controlling the amount of money in circulation. Monetarist theory asserts that variations in the money supply have major influences on national output in the short run and on price levels over longer periods. Monetarists assert that the objectives of monetary policy are best met by targeting the growth rate of the money supply rather than by engaging in discretionary monetary policy.Phillip Cagan, 1987. "Monetarism", '' The New Palgrave: A Dictionary of Economics'', v. 3, Reprinted in John Eatwell et al. (1989), ''Money: The New Palgrave'', pp. 195–205, 492–97. Monetarism is commonly associated with neoliberalism. Monetarism today is mainly associated with the work of Milton Friedman, who was among the generation of economists to reject Keynesian economics and criticise Keynes's theory of fighting economic downturns using fiscal policy ( government spending).

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. 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 restore full employment.) Hence, in the long run, the aggregate supply curve is vertical. * An ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Procyclical And Countercyclical
Procyclical and countercyclical variables are variables that fluctuate in a way that is positively or negatively correlated with business cycle fluctuations in gross domestic product (GDP). The scope of the concept may differ between the context of macroeconomic theory and that of economic policy–making. The concept is often encountered in the context of a government's approach to spending and taxation. A 'procyclical fiscal policy' can be summarised simply as governments choosing to increase government spending and reduce taxes during an economic expansion, but reduce spending and increase taxes during a recession. A 'countercyclical' fiscal policy takes the opposite approach: reducing spending and raising taxes during a boom period, and increasing spending and cutting taxes during a recession. Business cycle theory Procyclical In business cycle theory and finance, any economic quantity that is positively correlated with the overall state of the economy is said to be procyc ...

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 (which is considered "healthy" at the level in the range 2%–3%) and to increase employment. Additionally, it is designed to try to k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monetary Policy
Monetary policy is the policy adopted by the monetary authority of a nation to control either the interest rate payable for very short-term borrowing (borrowing by banks from each other to meet their short-term needs) or the money supply, often as an attempt to reduce inflation or the interest rate, to ensure price stability and general trust of the value and stability of the nation's currency. Monetary policy is a modification of the supply of money, i.e. "printing" more money, or decreasing the money supply by changing interest rates or removing excess reserves. This is in contrast to fiscal policy, which relies on taxation, government spending, and government borrowing as methods for a government to manage business cycle phenomena such as recessions. Further purposes of a monetary policy are usually to contribute to the stability of gross domestic product, to achieve and maintain low unemployment, and to maintain predictable exchange rates with other currencies.

Real Business Cycle
Real business-cycle theory (RBC theory) is a class of new classical macroeconomics macroeconomic model, models in which business-cycle fluctuations are accounted for by Real vs. nominal in economics, real (in contrast to nominal) Shock (economics), shocks. Unlike other leading theories of the business cycle, RBC theory sees business cycle fluctuations as the economic efficiency, efficient response to exogenous variable, exogenous changes in the real economic environment. That is, the level of national output necessarily maximizes expected utility, ''expected'' utility, and governments should therefore concentrate on long-run structural policy changes and not intervene through discretionary fiscal policy, fiscal or monetary policy, monetary policy designed to actively smooth out economic short-term fluctuations. According to RBC theory, business cycles are therefore "Real versus nominal value (economics), real" in that they do not represent a failure of Market clearing, markets to c ...

Aggregate Demand
In macroeconomics, 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: ...

Keynesian Economics
Keynesian economics ( ; sometimes Keynesianism, named after British economist John Maynard Keynes) are the various macroeconomic theories and models of how aggregate demand (total spending in the economy) strongly influences economic output and inflation. In the Keynesian view, aggregate demand does not necessarily equal the productive capacity of the economy. Instead, it is influenced by a host of factors – sometimes behaving erratically – affecting 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 – a recession, when demand is low, or inflation, when demand is high. Further, they argue that these economic fluctuations can be mitigated by economic policy responses coordinated between government and central bank. In particular, fiscal policy actions (taken by the government) and monetary policy actions (t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Maynard Keynes
John Maynard Keynes, 1st Baron Keynes, ( ; 5 June 1883 – 21 April 1946), was an English economist 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 school of thought known as Keynesian economics, and its various offshoots. His ideas, reformulated as New Keynesianism, are fundamental to mainstream macroeconomics. Keynes's intellect was evident early in life; in 1902, he gained admittance to the competitive mathematics program at King's College at the University of Cambridge. During the Great Depression of the 1930s, Keynes spearheaded a revolution in economic thinking, challenging the ideas of neoclassical economics that held that free markets would, in the short to medium term, a ...
