Keynesian economics are the various macroeconomic theories and models of how aggregate demand 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.
Macroeconomics is a branch of economics that deals with the 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.
In economics, stagflation or recession-inflation is a situation in which the inflation rate is high or increasing, the economic growth rate slows, and unemployment remains steadily high. It presents a dilemma for economic policy, since actions intended to lower inflation may exacerbate unemployment.
In economics and political science, fiscal policy is the use of government revenue collection 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. Additionally, it is designed to try to keep GDP growth at 2%–3% and the unemployment rate near the natural unemployment rate of 4%–5%. This implies that fiscal policy is used to stabilise the economy over the course of the business cycle.
Supply-side economics is a macroeconomic theory that postulates economic growth can be most effectively fostered by lowering taxes, decreasing regulation, and allowing free trade. According to supply-side economics, consumers will benefit from greater supplies of goods and services at lower prices, and employment will increase. Supply-side fiscal policies are designed to increase aggregate supply, as opposed to aggregate demand, thereby expanding output and employment while lowering prices. Such policies are of several general varieties:
- Investments in human capital, such as education, healthcare, and encouraging the transfer of technologies and business processes, to improve productivity. Encouraging globalized free trade via containerization is a major recent example.
- Tax reduction, to provide incentives to work, invest and take risks. Lowering income tax rates and eliminating or lowering tariffs are examples of such policies.
- Investments in new capital equipment and research and development (R&D), to further improve productivity. Allowing businesses to depreciate capital equipment more rapidly gives them an immediate financial incentive to invest in such equipment.
- Reduction in government regulations, to encourage business formation and expansion.
The Ricardian equivalence proposition 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.
In economics, the fiscal multiplier is the ratio of change in national income arising from a change in government spending. More generally, the exogenous spending multiplier is the ratio of change in national income arising from any autonomous change in spending. When this multiplier exceeds one, the enhanced effect on national income may be called the multiplier effect. The mechanism that can give rise to a multiplier effect is that an initial incremental amount of spending can lead to increased income and hence increased consumption spending, increasing income further and hence further increasing consumption, etc., resulting in an overall increase in national income greater than the initial incremental amount of spending. In other words, an initial change in aggregate demand may cause a change in aggregate output that is a multiple of the initial change.
The economy of governments covers the systems for setting levels of taxation, government budgets, the money supply and interest rates as well as the labour market, national ownership, and many other areas of government interventions into the economy.
Within the budgetary process, deficit spending is the amount by which spending exceeds revenue over a particular period of time, also called simply deficit, or budget deficit; the opposite of budget surplus. The term may be applied to the budget of a government, private company, or individual. Government deficit spending was first identified as a necessary economic tool by John Maynard Keynes in the wake of the Great Depression. It is a central point of controversy in economics, as discussed below.
The government budget balance, also alternatively referred to as general government balance, public budget balance, or public fiscal balance, is the overall difference between government revenues and spending. A positive balance is called a government budget surplus, and a negative balance is a government budget deficit. A government budget is a financial statement presenting the government's proposed revenues and spending for a financial year. A budget is prepared for each level of government and takes into account public social security obligations.
A macroeconomic model is an analytical tool designed to describe the operation of the problems of economy of a country or a region. These models are usually designed to examine the comparative statics and dynamics of aggregate quantities such as the total amount of goods and services produced, total income earned, the level of employment of productive resources, and the level of prices.

Fiscalism is a term sometimes used to refer the economic theory that the government should rely on fiscal policy as the main instrument of macroeconomic policy. Fiscalism in this sense is contrasted with monetarism, which is associated with reliance on monetary policy. Fiscalists reject monetarism in a non-convertible floating rate system as inefficient if not also ineffective
A balanced budget is a budget in which revenues are equal to expenditures. Thus, neither a budget deficit nor a budget surplus exists. 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.
Modern Monetary Theory or Modern Money Theory (MMT) is a heterodox macroeconomic theory that describes currency as a public monopoly and unemployment as evidence that a currency monopolist is overly restricting the supply of the financial assets needed to pay taxes and satisfy savings desires. MMT is opposed to the mainstream understanding of macroeconomic theory and has been criticized heavily by many mainstream economists.
Georgios Alogoskoufis is a professor of economics at the Athens University of Economics and Business since 1990. He was a member of the Hellenic Parliament from September 1996 till October 2009 and served as Greece's Minister of Economy and Finance from March 2004 till January 2009.
The Vuskovic Plan was the basis for the economic policy of the Popular Unity (UP) government of Chilean President Salvador Allende. It was drafted by and named after his first Economics Minister Pedro Vuskovic, who had worked before with the CEPAL. Although good results were obtained in 1970, hyperinflation made a comeback in 1972. By 1973, Chile was in shambles – inflation was hundreds of percents, the country had no foreign reserves, and GDP was falling.
Functional finance is an economic theory proposed by Abba P. Lerner, based on effective demand principles and chartalism. It states that government should finance itself to meet explicit goals, such as taming the business cycle, achieving full employment, ensuring growth, and low inflation.
A fiscal council is an independent body set up by a government to evaluate its expenditure and tax policy. Typically, councils are staffed by economists and statisticians who do not have the ability to set policy, but provide advice to governments and the public on the economic effects of government budgets and policy proposals. Some fiscal councils also provide economic forecasting. Fiscal councils evaluate government's fiscal policies, plans and performance publicly and independently, against macroeconomic objectives related to the long-term sustainability of public finances, short-to-medium-term macroeconomic stability, and other official objectives.
Crowding-in is a phenomenon that occurs when higher government spending leads to an increase in economic growth and therefore encourages firms to invest due to the presence of more profitable investment opportunities. The crowding-in effect is observed when there is an increase in private investment due to increased public investment, for example, through the construction or improvement of physical infrastructures such as roads, highways, water and sanitation, ports, airports, railways, etc. According to Post – Keynesian macroeconomics views, in a modern economy operating below capacity, government borrowings can increase demand by generating employment, thereby encouraging private investment, thus leading to crowding-in.
