Crowding out (economics)In economics, crowding out is a phenomenon that occurs when increased government involvement in a sector of the market economy substantially affects the remainder of the market, either on the supply or demand side of the market. One type frequently discussed is when expansionary fiscal policy reduces investment spending by the private sector. The government spending is "crowding out" investment because it is demanding more loanable funds and thus causing increased interest rates and therefore reducing investment spending.
Multiplier (economics)In macroeconomics, a multiplier is a factor of proportionality that measures how much an endogenous variable changes in response to a change in some exogenous variable. For example, suppose variable x changes by k units, which causes another variable y to change by M × k units. Then the multiplier is M. Two multipliers are commonly discussed in introductory macroeconomics. Commercial banks create money, especially under the fractional-reserve banking system used throughout the world.
Transfer paymentIn macroeconomics and finance, a transfer payment (also called a government transfer or simply fiscal transfer) is a redistribution of income and wealth by means of the government making a payment, without goods or services being received in return. These payments are considered to be non-exhaustive because they do not directly absorb resources or create output. Examples of transfer payments include welfare, financial aid, social security, and government subsidies for certain businesses.
Balanced budgetA balanced budget (particularly that of a government) is a budget in which revenues are equal to expenditures. Thus, neither a budget deficit nor a budget surplus exists (the accounts "balance"). More generally, it is a budget that has no budget deficit, but could possibly have a budget surplus. A cyclically balanced budget is a budget that is not necessarily balanced year-to-year but is balanced over the economic cycle, running a surplus in boom years and running a deficit in lean years, with these offsetting over time.
Ricardian equivalenceThe Ricardian equivalence proposition (also known as the Ricardo–de Viti–Barro equivalence theorem) is an economic hypothesis holding that consumers are forward-looking and so internalize the government's budget constraint when making their consumption decisions. This leads to the result that, for a given pattern of government spending, the method of financing such spending does not affect agents' consumption decisions, and thus, it does not change aggregate demand.
Government revenueGovernment revenue or national revenue is money received by a government from taxes and non-tax sources to enable it to undertake public expenditure. Government revenue as well as government spending are components of the government budget and important tools of the government's fiscal policy. The collection of revenue is the most basic task of a government, as revenue is necessary for the operation of government, provision of the common good (through the social contract in order to fulfill the public interest) and enforcement of its laws; this necessity of revenue was a major factor in the development of the modern bureaucratic state.
Generational accountingGenerational accounting is a method of measuring the fiscal burdens facing current and future generations. Generational accounting considers how much each adult generation, on a per person basis, is likely to pay in future taxes net of transfer payments, over the rest of their lives. Laurence Kotlikoff's individual and co-authored work on the relativity of fiscal language demonstrates that conventional fiscal measures, including the government's deficit, are not well defined from the perspective of economic theory.
Real interest rateThe real interest rate is the rate of interest an investor, saver or lender receives (or expects to receive) after allowing for inflation. It can be described more formally by the Fisher equation, which states that the real interest rate is approximately the nominal interest rate minus the inflation rate. If, for example, an investor were able to lock in a 5% interest rate for the coming year and anticipated a 2% rise in prices, they would expect to earn a real interest rate of 3%.
Natural rate of unemploymentThe natural rate of unemployment is the name that was given to a key concept in the study of economic activity. Milton Friedman and Edmund Phelps, tackling this 'human' problem in the 1960s, both received the Nobel Memorial Prize in Economic Sciences for their work, and the development of the concept is cited as a main motivation behind the prize. A simplistic summary of the concept is: 'The natural rate of unemployment, when an economy is in a steady state of "full employment", is the proportion of the workforce who are unemployed'.
Economic expansionAn economic expansion is an increase in the level of economic activity, and of the goods and services available. It is a period of economic growth as measured (for example) by a rise in real GDP. The explanation of fluctuations in aggregate economic activity between economic expansions and contractions ("booms" and "busts" within the "business cycle") is one of the primary concerns of macroeconomics.{ Typically an economic expansion is marked by an upturn in production and in utilization of resources.
