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.
Most factors of economic policy can be divided into either fiscal policy, which deals with government actions regarding taxation and spending, or monetary policy, which deals with central banking actions regarding the money supply and interest rates.
Such policies are often influenced by international institutions like the International Monetary Fund or World Bank as well as political beliefs and the consequent policies of parties.
Almost every aspect of government has an important economic component. A few examples of the kinds of economic policies that exist include: 
Stabilization policy attempts to stimulate an economy out of recession or constrain the money supply to prevent excessive inflation.
Policy is generally directed to achieve particular objectives, like targets for inflation, unemployment, or economic growth. Sometimes other objectives, like military spending or nationalization are important.
These are referred to as the policy goals: the outcomes which the economic policy aims to achieve.
To achieve these goals, governments use policy tools which are under the control of the government. These generally include the interest rate and money supply, tax and government spending, tariffs, exchange rates, labor market regulations, and many other aspects of government.
Government and central banks are limited in the number of goals they can achieve in the short term. For instance, there may be pressure on the government to reduce inflation, reduce unemployment, and reduce interest rates while maintaining currency stability. If all of these are selected as goals for the short term, then policy is likely to be incoherent, because a normal consequence of reducing inflation and maintaining currency stability is increasing unemployment and increasing interest rates.
This dilemma can in part be resolved by using microeconomic supply-side policy to help adjust markets. For instance, unemployment could potentially be reduced by altering laws relating to trade unions or unemployment insurance, as well as by macroeconomic (demand-side) factors like interest rates.
For much of the 20th century, governments adopted discretionary policies like demand management designed to correct the business cycle. These typically used fiscal and monetary policy to adjust inflation, output and unemployment.
However, following the stagflation of the 1970s, policymakers began to be attracted to policy rules.
A discretionary policy is supported because it allows policymakers to respond quickly to events. However, discretionary policy can be subject to dynamic inconsistency: a government may say it intends to raise interest rates indefinitely to bring inflation under control, but then relax its stance later. This makes policy non-credible and ultimately ineffective.
A rule-based policy can be more credible, because it is more transparent and easier to anticipate. Examples of rule-based policies are fixed exchange rates, interest rate rules, the stability and growth pact and the Golden Rule. Some policy rules can be imposed by external bodies, for instance, the Exchange Rate Mechanism for currency.
A compromise between strict discretionary and strict rule-based policy is to grant discretionary power to an independent body. For instance, the Federal Reserve Bank, European Central Bank, Bank of England and Reserve Bank of Australia all set interest rates without government interference, but do not adopt rules.
Another type of non-discretionary policy is a set of policies that are imposed by an international body. This can occur (for example) as a result of intervention by the International Monetary Fund.
The first economic problem was how to gain the resources it needed to be able to perform the functions of an early government: the military, roads and other projects like building the Pyramids.
Early governments generally relied on tax in kind and forced labor for their economic resources. However, with the development of money came the first policy choice. A government could raise money through taxing its citizens. However, it could now also debase the coinage and so increase the money supply.
Early civilizations also made decisions about whether to permit and how to tax trade. Some early civilizations, such as Ptolemaic Egypt adopted a closed currency policy whereby foreign merchants had to exchange their coin for local money. This effectively levied a very high tariff on foreign trade.
By the early modern age, more policy choices had been developed. There was considerable debate about mercantilism and other restrictive trade practices like the Navigation Acts, as trade policy became associated with both national wealth and with foreign and colonial policy.
Throughout the 19th Century, monetary standards became an important issue. Gold and silver were in supply in different proportions. Which metal was adopted influenced the wealth of different groups in society.
With the accumulation of private capital in the Renaissance, states developed methods of financing deficits without debasing their coin. The development of capital markets meant that a government could borrow money to finance war or expansion while causing less economic hardship.
This was the beginning of modern fiscal policy.
The same markets made it easy for private entities to raise bonds or sell stock to fund private initiatives.
The business cycle became a predominant issue in the 19th century, as it became clear that industrial output, employment, and profit behaved in a cyclical manner. One of the first proposed policy solutions to the problem came with the work of Keynes, who proposed that fiscal policy could be used actively to ward off depressions, recessions and slumps. The Austrian School of economics argues that central banks create the business cycle. After the dominance of monetarismry  and neoclassical thought that advised limiting the role of government in the economy in the second half of the twentieth century, the interventionist view has once more dominated the economic policy debate in response to the 2007-2008 financial crisis, 
A recent trend originating from medicine is to justify economic policy decisions with best available evidence.  While the previous approaches have been focused on macroeconomic policymaking aimed at sustaining promoting economic development and counteracting recessions, EBP is oriented towards all types of decisions concerned not only with anti-cyclical development but primarily with the growth-promoting policies. To gather evidence for such decisions, economists conduct randomized field experiments. The work of Banerjee, Duflo, and Kremer, the 2019 Nobel Prize laureates  exemplifies the gold type of evidence. However, the emphasis put on experimental evidence by the movement of evidence-based policy (and evidence-based medicine) results from the narrowly construed notion of intervention, which encompasses only policy decisions concerned with policymaking aimed at modifying causes to influence effects. In contrast to this idealized view of evidence-based policy movement, economic policymaking is a broader term that includes also institutional reforms and actions that do not require causal claims to be neutral under interventions. Such policy decisions can be grounded in, respectively, mechanistic evidence and correlational (econometric) studies. 
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 which 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. 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."
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, inflation is an increase in the general price level of goods and services in an economy. When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation corresponds to a reduction in the purchasing power of money. The opposite of inflation is deflation, a decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index. As prices faced by households do not all increase at the same rate, the consumer price index (CPI) is often used for this purpose. The employment cost index is also used for wages in the United States.
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. Monetarism is commonly associated with neoliberalism.
New Keynesian economics is a school of macroeconomics that strives to provide microeconomic foundations for Keynesian economics. It developed partly as a response to criticisms of Keynesian macroeconomics by adherents of new classical macroeconomics.

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.
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.
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 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.
In macroeconomics, a stabilization policy is a package or set of measures introduced to stabilize a financial system or economy. The term can refer to policies in two distinct sets of circumstances: business cycle stabilization or credit cycle stabilization. In either case, it is a form of discretionary policy.
Money creation, or money issuance, is the process by which the money supply of a country, or of an economic or monetary region, is increased. In most modern economies, money creation is controlled by the central banks. Money issued by central banks is termed base money. Central banks can increase the quantity of base money directly, by engaging in open market operations. However, the majority of the money supply is created by the commercial banking system in the form of bank deposits. Bank loans issued by commercial banks that practice fractional reserve banking expands the quantity of broad money to more than the original amount of base money issued by the central bank.
The Convertibility plan was a plan by the Argentine Currency Board that pegged the Argentine peso to the U.S. dollar between 1991 and 2002 in an attempt to eliminate hyperinflation and stimulate economic growth. While it initially met with considerable success, the board's actions ultimately failed. In contrast to what most people think, this peg actually did not exist, except only in the first years of the plan. From then on, the government never needed to use the foreign exchange reserves of the country in the maintenance of the peg, except when the recession and the massive bank withdrawals started in 2000.
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
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.

The following outline is provided as an overview of and topical guide to economics:
Inflationary bias is the outcome of discretionary monetary policy that leads to a higher than optimal level of inflation. Depending on the way expectations are formed in the private sector of the economy, there may or may not be a transitory income increase. The term may also refer to the practice of a public debt-ridden nation enacting policies which encourage inflation in the medium/long term.
David I. Meiselman was an American economist. Among his contributions to the field of economics are his work on the term structure of interest rates, the foundation today of the implementation of monetary policy by major central banks, and his work with Milton Friedman on the impact of monetary policy on the performance of the economy and inflation.
