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.
In economics, a recession is a business cycle contraction when there is a general decline in economic activity. Recessions generally occur when there is a widespread drop in spending. This may be triggered by various events, such as a financial crisis, an external trade shock, an adverse supply shock, the bursting of an economic bubble, or a large-scale anthropogenic or natural disaster. In the United States, it is defined as "a significant decline in economic activity spread across the market, lasting more than a few months, normally visible in real GDP, real income, employment, industrial production, and wholesale-retail sales". In the United Kingdom, it is defined as a negative economic growth for two consecutive quarters.
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 revenues and expenditures to influence macroeconomic variables developed as a result of the Great Depression, when the previous laissez-faire approach to economic management became unpopular. Fiscal policy is based on the theories of the British economist John Maynard Keynes, whose Keynesian economics theorized that government changes in the levels of taxation and government spending influences 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 stabilize the economy over the course of the business cycle.
Business cycles are intervals of expansion followed by recession in economic activity. They have implications for the welfare of the broad population as well as for private institutions. Typically business cycles are measured by applying a band pass filter to a broad economic indicator such as Real Gross Domestic Production. Here important problems may arise with a commonly used filter called the "ideal filter". For instance if a series is a purely random process without any cycle, an "ideal" filter, better called a block filter, a spurious cycle is produced as output. Fortunately methods such as [Harvey and Trimbur, 2003, Review of Economics and Statistics] have been designed so that the band pass filter may be adapted to the time series at hand.
Monetary economics is the branch of economics that studies the different competing theories of money: it provides a framework for analyzing money and considers its functions, and it considers how money can gain acceptance purely because of its convenience as a public good. The discipline has historically prefigured, and remains integrally linked to, macroeconomics. This branch also examines the effects of monetary systems, including regulation of money and associated financial institutions and international aspects.
A liquidity trap is a situation, described in Keynesian economics, in which, "after the rate of interest has fallen to a certain level, liquidity preference may become virtually absolute in the sense that almost everyone prefers holding cash rather than holding a debt which yields so low a rate of interest."

A financial crisis is any of a broad variety of situations in which some financial assets suddenly lose a large part of their nominal value. In the 19th and early 20th centuries, many financial crises were associated with banking panics, and many recessions coincided with these panics. Other situations that are often called financial crises include stock market crashes and the bursting of other financial bubbles, currency crises, and sovereign defaults. Financial crises directly result in a loss of paper wealth but do not necessarily result in significant changes in the real economy.

The Deutsche Bank Prize in Financial Economics honors renowned researchers who have made influential contributions to the fields of finance and money and macroeconomics, and whose work has led to practical and policy-relevant results. It is awarded biannually, since 2005, by the Center for Financial Studies (CFS), in partnership with Goethe University Frankfurt, and is sponsored by Deutsche Bank Donation Fund. The award carries an endowment of €50,000, which is donated by the Stiftungsfonds Deutsche Bank im Stifterverband für die Deutsche Wissenschaft.
The Great Recession was a period of marked general decline (recession) observed in national economies globally that occurred between 2007 and 2009. The scale and timing of the recession varied from country to country. At the time, the International Monetary Fund (IMF) concluded that it was the most severe economic and financial meltdown since the Great Depression. One result was a serious disruption of normal international relations.
Following the global financial crisis of 2007–2008, there was a worldwide resurgence of interest in Keynesian economics among prominent economists and policy makers. This included discussions and implementation of economic policies in accordance with the recommendations made by John Maynard Keynes in response to the Great Depression of the 1930s, most especially fiscal stimulus and expansionary monetary policy.
In macroeconomics, particularly in the history of economic thought, the Treasury view is the assertion that fiscal policy has no effect on the total amount of economic activity and unemployment, even during times of economic recession. This view was most famously advanced in the 1930s by the staff of the British Chancellor of the Exchequer. The position can be characterized as:
Any increase in government spending necessarily crowds out an equal amount of private spending or investment, and thus has no net impact on economic activity.
In economics, stimulus refers to attempts to use monetary policy or fiscal policy to stimulate the economy. Stimulus can also refer to monetary policies such as lowering interest rates and quantitative easing.
Macroeconomic theory has its origins in the study of business cycles and monetary theory. In general, early theorists believed monetary factors could not affect real factors such as real output. John Maynard Keynes attacked some of these "classical" theories and produced a general theory that described the whole economy in terms of aggregates rather than individual, microeconomic parts. Attempting to explain unemployment and recessions, he noticed the tendency for people and businesses to hoard cash and avoid investment during a recession. He argued that this invalidated the assumptions of classical economists who thought that markets always clear, leaving no surplus of goods and no willing labor left idle.

The Great Recession in the United States was a severe financial crisis combined with a deep recession. While the recession officially lasted from December 2007 to June 2009, it took many years for the economy to recover to pre-crisis levels of employment and output. This slow recovery was due in part to households and financial institutions paying off debts accumulated in the years preceding the crisis along with restrained government spending following initial stimulus efforts. It followed the bursting of the housing bubble, the housing market correction and subprime mortgage crisis.
Growth in a Time of Debt, also known by its authors' names as Reinhart–Rogoff, is an economics paper by American economists Carmen Reinhart and Kenneth Rogoff published in a non peer-reviewed issue of the American Economic Review in 2010. Politicians, commentators, and activists widely cited the paper in political debates over the effectiveness of austerity in fiscal policy for debt-burdened economies. The paper argues that when "gross external debt reaches 60 percent of GDP", a country's annual growth declined by two percent, and "for levels of external debt in excess of 90 percent" GDP growth was "roughly cut in half." Appearing in the aftermath of the financial crisis of 2007–2008, the evidence for the 90%-debt threshold hypothesis provided support for pro-austerity policies.
