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: ...

Macroeconomics
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 Gross domestic product, GDP (Gross Domestic Product), unemployment (including Unemployment#Measurement, unemployment rates), national income, price index, price indices, output (economics), output, Consumption (economics), consumption, inflation, saving, investment (macroeconomics), investment, Energy economics, energy, international trade, and international finance. ...

Physical Capital
Physical capital represents in economics one of the three primary factors of production. Physical capital is the apparatus used to produce a good and services. Physical capital represents the tangible man-made goods that help and support the production. Inventory, cash, equipment or real estate are all examples of physical capital. Definition N.G. Mankiw definition from the book Economics: ''Capital is the equipment and structures used to produce goods and services. Physical capital consists of man-made goods (or input into the process of production) that assist in the production process. Cash, real estate, equipment, and inventory are examples of physical capital.'' Capital goods represents one of the key factors of corporation function. Generally, capital allows a company to preserve liquidity while growing operations, it refers to physical assets in business and the way a company have reached their physical capital. While referring how companies have obtained their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Consumption Function
In economics, the consumption function describes a relationship between consumption and disposable income. The concept is believed to have been introduced into macroeconomics by John Maynard Keynes in 1936, who used it to develop the notion of a government spending multiplier. Details Its simplest form is the ''linear consumption function'' used frequently in simple Keynesian models: :C = a + b \cdot Y_ where a is the autonomous consumption that is independent of disposable income; in other words, consumption when disposable income is zero. The term b \cdot Y_ is the induced consumption that is influenced by the economy's income level Y_. The parameter b is known as the marginal propensity to consume, i.e. the increase in consumption due to an incremental increase in disposable income, since \partial C / \partial Y_ = b. Geometrically, b is the slope of the consumption function. Keynes proposed this model to fit three stylized facts: * People typically spend a part, but ...

Velocity Of Money
image:M3 Velocity in the US.png, 300px, Similar chart showing the logged velocity (green) of a broader measure of money M3 that covers M2 plus large institutional deposits. The US no longer publishes official M3 measures, so the chart only runs through 2005. The velocity of money measures the number of times that the average unit of currency is used to purchase goods and services within a given time period. The concept relates the size of economic activity to a given money supply, and the speed of money exchange is one of the variables that determine inflation. The measure of the velocity of money is usually the ratio of the gross national product (GNP) to a country's money supply. If the velocity of money is increasing, then transactions are occurring between individuals more frequently. The velocity of money changes over time and is influenced by a variety of factors. Illustration If, for example, in a very small economy, a farmer and a mechanic, with just $50 between them, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Involuntary Unemployment
Involuntary unemployment occurs when a person is unemployed despite being willing to work at the prevailing wage. It is distinguished from voluntary unemployment, where a person refuses to work because their reservation wage is higher than the prevailing wage. In an economy with involuntary unemployment, there is a surplus of labor at the current real wage. This occurs when there is some force that prevents the real wage rate from decreasing to the real wage rate that would equilibrate supply and demand (such as a minimum wage above the market-clearing wage). Structural unemployment is also involuntary. Economists have several theories explaining the possibility of involuntary unemployment including implicit contract theory, disequilibrium theory, staggered wage setting, and efficiency wages. The officially measured unemployment rate is the ratio of involuntary unemployment to the sum of involuntary unemployment and employment (the denominator of this ratio being the total ...

Wall Street Crash Of 1929
The Wall Street Crash of 1929, also known as the Great Crash, was a major American stock market crash that occurred in the autumn of 1929. It started in September and ended late in October, when share prices on the New York Stock Exchange collapsed. It was the most devastating stock market crash in the history of the United States, when taking into consideration the full extent and duration of its aftereffects. The Great Crash is mostly associated with October 24, 1929, called ''Black Thursday'', the day of the largest sell-off of shares in U.S. history, and October 29, 1929, called ''Black Tuesday'', when investors traded some 16 million shares on the New York Stock Exchange in a single day. The crash, which followed the London Stock Exchange's crash of September, signaled the beginning of the Great Depression. Background The "Roaring Twenties", the decade following World War I that led to the crash, was a time of wealth and excess. Building on post-war optimism, rural Amer ...

Great Depression
The Great Depression (19291939) was an economic shock that impacted most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States. The economic contagion began around September and led to the Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century. Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II. Devastating effects were seen in both rich and poor countries with falling personal income, prices, tax revenues, and profits. International trade fell by more than 50%, unemployment in the U.S. rose to 23% an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The General Theory Of Employment, Interest And Money
''The General Theory of Employment, Interest and Money'' is a book by English economist John Maynard Keynes published in February 1936. It caused a profound shift in economic thought, giving macroeconomics a central place in economic theory and contributing much of its terminology – the " Keynesian Revolution". It had equally powerful consequences in economic policy, being interpreted as providing theoretical support for government spending in general, and for budgetary deficits, monetary intervention and counter-cyclical policies in particular. It is pervaded with an air of mistrust for the rationality of free-market decision making. Keynes denied that an economy would automatically adapt to provide full employment even in equilibrium, and believed that the volatile and ungovernable psychology of markets would lead to periodic booms and crises. The ''General Theory'' is a sustained attack on the classical economics orthodoxy of its time. It introduced the concepts of the con ...

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. * A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AD–AS Model
The AD–AS or aggregate demand–aggregate supply model is a macroeconomic model that explains price level and output through the relationship of aggregate demand (AD) and aggregate supply (AS). It is based on the theory of John Maynard Keynes presented in his work '' The General Theory of Employment, Interest and Money''. It is one of the primary simplified representations in the modern field of macroeconomics, and is used by a broad array of economists, from libertarian, monetarist supporters of laissez-faire, such as Milton Friedman, to post-Keynesian supporters of economic interventionism, such as Joan Robinson. Modeling The AD/AS model is used to illustrate the Keynesian model of the business cycle. Movements of the two curves can be used to predict the effects that various exogenous events will have on two variables: real GDP and the price level. Furthermore, the model can be incorporated as a component in any of a variety of dynamic models (models of how variables lik ...

Investment (macroeconomics)
In macroeconomics, investment "consists of the additions to the nation's capital stock of buildings, equipment, software, and inventories during a year" or, alternatively, investment spending — "spending on productive physical capital such as machinery and construction of buildings, and on changes to inventories — as part of total spending" on goods and services per year. Krugman, Paul and Robin Wells (2012), 2nd ed. ''Economics'', p. 593. Worth Publishers. The types of investment include residential investment in housing that will provide a flow of housing services over an extended time, non-residential fixed investment in things such as new machinery or factories, human capital investment in workforce education, and inventory investment (the accumulation, intentional or unintentional, of goods inventories) In measures of national income and output, "gross investment" (represented by the variable ) is a component of gross domestic product (), given in the formula , wh ...
