In economics, a recession is a business cycle contraction that occurs 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.
Uncertainty refers to epistemic situations involving imperfect or unknown information. It applies to predictions of future events, to physical measurements that are already made, or to the unknown. Uncertainty arises in partially observable or stochastic environments, as well as due to ignorance, indolence, or both. It arises in any number of fields, including insurance, philosophy, physics, statistics, economics, finance, medicine, psychology, sociology, engineering, metrology, meteorology, ecology and information science.

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.
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.
Frank Hyneman Knight was an American economist who spent most of his career at the University of Chicago, where he became one of the founders of the Chicago School. Nobel laureates Milton Friedman, George Stigler and James M. Buchanan were all students of Knight at Chicago. Ronald Coase said that Knight, without teaching him, was a major influence on his thinking. F.A. Hayek considered Knight to be one of the major figures in preserving and promoting classical liberal thought in the twentieth century. Paul Samuelson named Knight as one of the several "American saints in economics" born after 1860.
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 referred to as the general government balance, public budget balance, or public fiscal balance, is the difference between government revenues and spending. For a government that uses accrual accounting the budget balance is calculated using only spending on current operations, with expenditure on new capital assets excluded. A positive balance is called a government budget surplus, and a negative balance is a government budget deficit. A government budget presents the government's proposed revenues and spending for a financial year.
In finance, systemic risk is the risk of collapse of an entire financial system or entire market, as opposed to the risk associated with any one individual entity, group or component of a system, that can be contained therein without harming the entire system. It can be defined as "financial system instability, potentially catastrophic, caused or exacerbated by idiosyncratic events or conditions in financial intermediaries". It refers to the risks imposed by interlinkages and interdependencies in a system or market, where the failure of a single entity or cluster of entities can cause a cascading failure, which could potentially bankrupt or bring down the entire system or market. It is also sometimes erroneously referred to as "systematic risk".
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.
Procyclical and countercyclical variables are variables that fluctuate in a way that is positively or negatively correlated with business cycle fluctuations in gross domestic product (GDP). The scope of the concept may differ between the context of macroeconomic theory and that of economic policy–making.
In finance, risk factors are the building blocks of investing, that help explain the systematic returns in equity market, and the possibility of losing money in investments or business adventures. A risk factor is a concept in finance theory such as the capital asset pricing model, arbitrage pricing theory and other theories that use pricing kernels. In these models, the rate of return of an asset is a random variable whose realization in any time period is a linear combination of other random variables plus a disturbance term or white noise. In practice, a linear combination of observed factors included in a linear asset pricing model proxy for a linear combination of unobserved risk factors if financial market efficiency is assumed. In the Intertemporal CAPM, non-market factors proxy for changes in the investment opportunity set.
Foreign exchange risk is a financial risk that exists when a financial transaction is denominated in a currency other than the domestic currency of the company. The exchange risk arises when there is a risk of an unfavourable change in exchange rate between the domestic currency and the denominated currency before the date when the transaction is completed.
Political risk is a type of risk faced by investors, corporations, and governments that political decisions, events, or conditions will significantly affect the profitability of a business actor or the expected value of a given economic action. Political risk can be understood and managed with reasoned foresight and investment.
The Fat Tail: The Power of Political Knowledge for Strategic Investing is a book by political scientists Ian Bremmer and Preston Keat. Bremmer and Keat are President and Research Director, respectively, of Eurasia Group, a global political risk consultancy.
Beginning in 2008 many nations of the world enacted fiscal stimulus plans in response to the Great Recession. These nations used different combinations of government spending and tax cuts to boost their sagging economies. Most of these plans were based on the Keynesian theory that deficit spending by governments can replace some of the demand lost during a recession and prevent the waste of economic resources idled by a lack of demand. The International Monetary Fund recommended that countries implement fiscal stimulus measures equal to 2% of their GDP to help offset the global contraction. In subsequent years, fiscal consolidation measures were implemented by some countries in an effort to reduce debt and deficit levels while at the same time stimulating economic recovery.
A global saving glut is a situation in which desired saving exceeds desired investment. By 2005 Ben Bernanke, chairman of the Federal Reserve, the central bank of the United States, expressed concern about the "significant increase in the global supply of saving" and its implications for monetary policies, particularly in the United States. Although Bernanke's analyses focused on events in 2003 to 2007 that led to the 2007–2009 financial crisis, regarding GSG countries and the United States, excessive saving by the non-financial corporate sector (NFCS) is an ongoing phenomenon, affecting many countries. Bernanke's global saving glut (GSG) hypothesis argued that increased capital inflows to the United States from GSG countries were an important reason that U.S. longer-term interest rates from 2003 to 2007 were lower than expected.
In simple terms, risk is the possibility of something bad happening. Risk involves uncertainty about the effects/implications of an activity with respect to something that humans value, often focusing on negative, undesirable consequences. Many different definitions have been proposed. The international standard definition of risk for common understanding in different applications is "effect of uncertainty on objectives".
Corporate finance is the area of finance that deals with the sources of funding, and the capital structure of corporations, the actions that managers take to increase the value of the firm to the shareholders, and the tools and analysis used to allocate financial resources. The primary goal of corporate finance is to maximize or increase shareholder value.
The economic effects of Brexit were a major area of debate during and after the referendum on UK membership of the European Union. The majority of economists believe that Brexit is likely to harm the UK's economy and reduce its real per capita income in the long term, and the referendum itself damaged the economy. It is likely to produce a large decline in immigration from countries in the European Economic Area (EEA) to the UK, and poses challenges for British higher education and academic research.
