Macroeconomic indicators such as GDP ( gross domestic product ), investment spending, capacity utilization, household income, business profits, and inflation fall, while bankruptcies and the unemployment rate rise. In the United Kingdom, it is defined as a negative economic growth for two consecutive quarters. Recessions generally occur when there is a widespread drop in spending ( an adverse demand shock ). This may be triggered by various events, such as a financial crisis, an external trade shock, an adverse supply shock or the bursting of an economic bubble. Governments usually respond to recessions by adopting expansionary macroeconomic policies, such as increasing money supply, increasing government spending and decreasing taxation.

In time, the other rules of thumb were forgotten. Some economists prefer a definition of a 1.5 - 2 percentage points rise in unemployment within 12 months. In the United States, the Business Cycle Dating Committee of the National Bureau of Economic Research ( NBER ) is generally seen as the authority for dating US recessions. The NBER defines an economic recession as : `` a significant decline in economic activity spread across the economy, lasting more than a few months, normally visible in real GDP, real income, employment, industrial production, and wholesale - retail sales. '' Almost universally, academics, economists, policy makers, and businesses defer to the determination by the NBER for the precise dating of a recession 's onset and end. In the United Kingdom, recessions are generally defined as two consecutive quarters of negative economic growth, as measured by the seasonal adjusted quarter - on - quarter figures for real GDP. The exact same recession definition applies for all member states of the European Union. Attributes A recession has many attributes that can occur simultaneously and includes declines in component measures of economic activity ( GDP ) such as consumption, investment, government spending, and net export activity. These summary measures reflect underlying drivers such as employment levels and skills, household savings rates, corporate investment decisions, interest rates, demographics, and government policies. Economist Richard C. Koo wrote that under ideal conditions, a country 's economy should have the household sector as net savers and the corporate sector as net borrowers, with the government budget nearly balanced and net exports near zero. When these relationships become imbalanced, recession can develop within the country or create pressure for recession in another country. Policy responses are often designed to drive the economy back towards this ideal state of balance. A severe ( GDP down by 10 % ) or prolonged ( three or four years ) recession is referred to as an economic depression, although some argue that their causes and cures can be different. As an informal shorthand, economists sometimes refer to different recession shapes, such as V - shaped, U-shaped, L - shaped and W - shaped recessions. Type of recession or shape Main article : Recession shapes The type and shape of recessions are distinctive. In the US, V - shaped, or short - and - sharp contractions followed by rapid and sustained recovery, occurred in 1954 and 1990 -- 91 ; U-shaped ( prolonged slump ) in 1974 -- 75, and W - shaped, or double - dip recessions in 1949 and 1980 -- 82. Japan 's 1993 -- 94 recession was U-shaped and its 8 - out - of - 9 quarters of contraction in 1997 -- 99 can be described as L - shaped. Korea, Hong Kong and South - east Asia experienced U-shaped recessions in 1997 -- 98, although Thailand 's eight consecutive quarters of decline should be termed L - shaped. Psychological aspects Recessions have psychological and confidence aspects. For example, if companies expect economic activity to slow, they may reduce employment levels and save money rather than invest. Such expectations can create a self - reinforcing downward cycle, bringing about or worsening a recession. Consumer confidence is one measure used to evaluate economic sentiment. The term animal spirits has been used to describe the psychological factors underlying economic activity. Economist Robert J. Shiller wrote that the term ``... refers also to the sense of trust we have in each other, our sense of fairness in economic dealings, and our sense of the extent of corruption and bad faith. When animal spirits are on ebb, consumers do not want to spend and businesses do not want to make capital expenditures or hire people. '' Balance sheet recession Main article : Balance sheet recession High levels of indebtedness or the bursting of a real estate or financial asset price bubble can cause what is called a `` balance sheet recession. '' This is when large numbers of consumers or corporations pay down debt ( i.e., save ) rather than spend or invest, which slows the economy. The term balance sheet derives from an accounting identity that holds that assets must always equal the sum of liabilities plus equity. If asset prices fall below the value of the debt incurred to purchase them, then the equity must be negative, meaning the consumer or corporation is insolvent. Economist Paul Krugman wrote in 2014 that `` the best working hypothesis seems to be that the financial crisis was only one manifestation of a broader problem of excessive debt -- that it was a so - called `` balance sheet recession. '' In Krugman 's view, such crises require debt reduction strategies combined with higher government spending to offset declines from the private sector as it pays down its debt. For example, economist Richard Koo wrote that Japan 's `` Great Recession '' that began in 1990 was a `` balance sheet recession. '' It was triggered by a collapse in land and stock prices, which caused Japanese firms to have negative equity, meaning their assets were worth less than their liabilities. Despite zero interest rates and expansion of the money supply to encourage borrowing, Japanese corporations in aggregate opted to pay down their debts from their own business earnings rather than borrow to invest as firms typically do. Corporate investment, a key demand component of GDP, fell enormously ( 22 % of GDP ) between 1990 and its peak decline in 2003. Japanese firms overall became net savers after 1998, as opposed to borrowers. Koo argues that it was massive fiscal stimulus ( borrowing and spending by the government ) that offset this decline and enabled Japan to maintain its level of GDP. In his view, this avoided a U.S. type Great Depression, in which U.S. GDP fell by 46 %. He argued that monetary policy was ineffective because there was limited demand for funds while firms paid down their liabilities. In a balance sheet recession, GDP declines by the amount of debt repayment and un-borrowed individual savings, leaving government stimulus spending as the primary remedy. Krugman discussed the balance sheet recession concept during 2010, agreeing with Koo 's situation assessment and view that sustained deficit spending when faced with a balance sheet recession would be appropriate. However, Krugman argued that monetary policy could also affect savings behavior, as inflation or credible promises of future inflation ( generating negative real interest rates ) would encourage less savings. In other words, people would tend to spend more rather than save if they believe inflation is on the horizon. In more technical terms, Krugman argues that the private sector savings curve is elastic even during a balance sheet recession ( responsive to changes in real interest rates ) disagreeing with Koo 's view that it is inelastic ( non-responsive to changes in real interest rates ). A July 2012 survey of balance sheet recession research reported that consumer demand and employment are affected by household leverage levels. Both durable and non-durable goods consumption declined as households moved from low to high leverage with the decline in property values experienced during the subprime mortgage crisis. Further, reduced consumption due to higher household leverage can account for a significant decline in employment levels. Policies that help reduce mortgage debt or household leverage could therefore have stimulative effects. Liquidity trap A liquidity trap is a Keynesian theory that a situation can develop in which interest rates reach near zero ( zero interest - rate policy ) yet do not effectively stimulate the economy. In theory, near - zero interest rates should encourage firms and consumers to borrow and spend. However, if too many individuals or corporations focus on saving or paying down debt rather than spending, lower interest rates have less effect on investment and consumption behavior ; the lower interest rates are like `` pushing on a string. '' Economist Paul Krugman described the U.S. 2009 recession and Japan 's lost decade as liquidity traps. One remedy to a liquidity trap is expanding the money supply via quantitative easing or other techniques in which money is effectively printed to purchase assets, thereby creating inflationary expectations that cause savers to begin spending again. Government stimulus spending and mercantilist policies to stimulate exports and reduce imports are other techniques to stimulate demand. He estimated in March 2010 that developed countries representing 70 % of the world 's GDP were caught in a liquidity trap. Paradoxes of thrift and deleveraging Behavior that may be optimal for an individual ( e.g., saving more during adverse economic conditions ) can be detrimental if too many individuals pursue the same behavior, as ultimately one person 's consumption is another person 's income. Too many consumers attempting to save ( or pay down debt ) simultaneously is called the paradox of thrift and can cause or deepen a recession. Economist Hyman Minsky also described a `` paradox of deleveraging '' as financial institutions that have too much leverage ( debt relative to equity ) can not all de-leverage simultaneously without significant declines in the value of their assets. During April 2009, U.S. Federal Reserve Vice Chair Janet Yellen discussed these paradoxes : `` Once this massive credit crunch hit, it did n't take long before we were in a recession. The recession, in turn, deepened the credit crunch as demand and employment fell, and credit losses of financial institutions surged. Indeed, we have been in the grips of precisely this adverse feedback loop for more than a year. A process of balance sheet deleveraging has spread to nearly every corner of the economy. Consumers are pulling back on purchases, especially on durable goods, to build their savings. Businesses are cancelling planned investments and laying off workers to preserve cash. And, financial institutions are shrinking assets to bolster capital and improve their chances of weathering the current storm. Once again, Minsky understood this dynamic. He spoke of the paradox of deleveraging, in which precautions that may be smart for individuals and firms -- and indeed essential to return the economy to a normal state -- nevertheless magnify the distress of the economy as a whole. '' Predictors There are no known completely reliable predictors, but the following are considered possible predictors. Inverted yield curve, the model developed by economist Jonathan H. Wright, uses yields on 10 - year and three - month Treasury securities as well as the Fed 's overnight funds rate. Another model developed by Federal Reserve Bank of New York economists uses only the 10 - year / three - month spread. It is, however, not a definite indicator ; The three - month change in the unemployment rate and initial jobless claims. Index of Leading ( Economic ) Indicators ( includes some of the above indicators ). Lowering of asset prices, such as homes and financial assets, or high personal and corporate debt levels. Government responses See also : Stabilization policy Most mainstream economists believe that recessions are caused by inadequate aggregate demand in the economy, and favor the use of expansionary macroeconomic policy during recessions. Strategies favored for moving an economy out of a recession vary depending on which economic school the policymakers follow. Monetarists would favor the use of expansionary monetary policy, while Keynesian economists may advocate increased government spending to spark economic growth. Supply - side economists may suggest tax cuts to promote business capital investment. When interest rates reach the boundary of an interest rate of zero percent ( zero interest - rate policy ) conventional monetary policy can no longer be used and government must use other measures to stimulate recovery. Keynesians argue that fiscal policy -- tax cuts or increased government spending -- works when monetary policy fails. Spending is more effective because of its larger multiplier but tax cuts take effect faster. For example, Paul Krugman wrote in December 2010 that significant, sustained government spending was necessary because indebted households were paying down debts and unable to carry the U.S. economy as they had previously : `` The root of our current troubles lies in the debt American families ran up during the Bush - era housing bubble... highly indebted Americans not only ca n't spend the way they used to, they 're having to pay down the debts they ran up in the bubble years. This would be fine if someone else were taking up the slack. But what 's actually happening is that some people are spending much less while nobody is spending more -- and this translates into a depressed economy and high unemployment. What the government should be doing in this situation is spending more while the private sector is spending less, supporting employment while those debts are paid down. And this government spending needs to be sustained... '' Stock market Some recessions have been anticipated by stock market declines. In Stocks for the Long Run, Siegel mentions that since 1948, ten recessions were preceded by a stock market decline, by a lead time of 0 to 13 months ( average 5.7 months ), while ten stock market declines of greater than 10 % in the Dow Jones Industrial Average were not followed by a recession. The real - estate market also usually weakens before a recession. However real - estate declines can last much longer than recessions. Since the business cycle is very hard to predict, Siegel argues that it is not possible to take advantage of economic cycles for timing investments. Even the National Bureau of Economic Research ( NBER ) takes a few months to determine if a peak or trough has occurred in the US. During an economic decline, high yield stocks such as fast - moving consumer goods, pharmaceuticals, and tobacco tend to hold up better. However, when the economy starts to recover and the bottom of the market has passed ( sometimes identified on charts as a MACD ), growth stocks tend to recover faster. There is significant disagreement about how health care and utilities tend to recover. Diversifying one 's portfolio into international stocks may provide some safety ; however, economies that are closely correlated with that of the U.S. may also be affected by a recession in the U.S. There is a view termed the halfway rule according to which investors start discounting an economic recovery about halfway through a recession. In the 16 U.S. recessions since 1919, the average length has been 13 months, although the recent recessions have been shorter. Thus if the 2008 recession followed the average, the downturn in the stock market would have bottomed around November 2008. The actual US stock market bottom of the 2008 recession was in March 2009. Politics Generally an administration gets credit or blame for the state of economy during its time. This has caused disagreements about on actually started. In an economic cycle, a downturn can be considered a consequence of an expansion reaching an unsustainable state, and is corrected by a brief decline. Thus it is not easy to isolate the causes of specific phases of the cycle. The 1981 recession is thought to have been caused by the tight - money policy adopted by Paul Volcker, chairman of the Federal Reserve Board, before Ronald Reagan took office. Reagan supported that policy. Economist Walter Heller, chairman of the Council of Economic Advisers in the 1960s, said that `` I call it a Reagan - Volcker - Carter recession. The resulting taming of inflation did, however, set the stage for a robust growth period during Reagan 's administration. Economists usually teach that to some degree recession is unavoidable, and its causes are not well understood. Consequently, modern government administrations attempt to take steps, also not agreed upon, to soften a recession. Consequences Unemployment Unemployment is particularly high during a recession. Many economists working within the neoclassical paradigm argue that there is a natural rate of unemployment which, when subtracted from the actual rate of unemployment, can be used to calculate the negative GDP gap during a recession. In other words, unemployment never reaches 0 percent, and thus is not a negative indicator of the health of an economy unless above the `` natural rate, '' in which case it corresponds directly to a loss in gross domestic product, or GDP.

( August 2011 ) The full impact of a recession on employment may not be felt for several quarters. Research in Britain shows that low - skilled, low - educated workers and the young are most vulnerable to unemployment in a downturn. After recessions in Britain in the 1980s and 1990s, it took five years for unemployment to fall back to its original levels. Many companies often expect employment discrimination claims to rise during a recession. Business Productivity tends to fall in the early stages of a recession, then rises again as weaker firms close. The variation in profitability between firms rises sharply. Recessions have also provided opportunities for anti-competitive mergers, with a negative impact on the wider economy : the suspension of competition policy in the United States in the 1930s may have extended the Great Depression. Social effects The living standards of people dependent on wages and salaries are not more affected by recessions than those who rely on fixed incomes or welfare benefits. The loss of a job is known to have a negative impact on the stability of families, and individuals ' health and well - being. Fixed income benefits receive small cuts which make it tougher to survive. History Global Main article : Global recession According to the International Monetary Fund ( IMF ), `` Global recessions seem to occur over a cycle lasting between eight and 10 years. '' The IMF takes many factors into account when defining a global recession. Until April 2009, IMF several times communicated to the press, that a global annual real GDP growth of 3.0 percent or less in their view was ``... equivalent to a global recession. '' By this measure, six periods since 1970 qualify : 1974 -- 1975, 1980 -- 1983, 1990 -- 1993, 1998, 2001 -- 2002, and 2008 -- 2009. During what IMF in April 2002 termed the past three global recessions of the last three decades, global per capita output growth was zero or negative, and IMF argued -- at that time -- that because of the opposite being found for 2001, the economic state in this year by itself did not qualify as a global recession. In April 2009, IMF had changed their Global recession definition to : A decline in annual per ‐ capita real World GDP ( purchasing power parity weighted ), backed up by a decline or worsening for one or more of the seven other global macroeconomic indicators : Industrial production, trade, capital flows, oil consumption, unemployment rate, per ‐ capita investment, and per ‐ capita consumption. By this new definition, a total of four global recessions took place since World War II : 1975, 1982, 1991 and 2009. All of them only lasted one year, although the third would have lasted three years ( 1991 -- 93 ) if IMF as criteria had used the normal exchange rate weighted per ‐ capita real World GDP rather than the purchase power parity weighted per ‐ capita real World GDP. Australia The worst recession Australia has ever suffered happened in the beginning of the 1930s. As a result of late 1920s profit issues in agriculture and cutbacks, 1931 - 1932 saw Australia 's biggest recession in its entire history. It fared better than other nations, that underwent depressions, but their poor economic states influenced Australia 's as well, that depended on them for export, as well as foreign investments. The nation also benefited from bigger productivity in manufacturing, facilitated by trade protection, which also helped with feeling the effects less. Due to a credit squeeze, the economy had gone into a brief recession in 1961 Australia was facing a rising level of inflation in 1973, caused partially by the oil crisis happening in that same year, which brought inflation at a 13 % increase. Economic recession hit by the middle of the year 1974, with no change in policy enacted by the government as a measure to counter the economic situation of the country. Consequently, the unemployment level rose and the trade deficit increased significantly. Another recession -- the most recent one to date -- came in the 1990s, at the beginning of the decade. It was the result of a major stock collapse in 1987, in October, referred to now as Black Monday. Although the collapse was larger than the one in 1929, the global economy recovered quickly, but North America still suffered a decline in lumbering savings and loans, which led to a crisis. The recession was n't limited to only America, but it also affected partnering nations, such as Australia. The unemployment level increased to 10.8 %, employment declined by 3.4 % and the GDP also decreased as much as 1.7 %. Inflation, however, was successfully reduced. United Kingdom Main article : List of recessions in the United Kingdom The most recent recession to affect the United Kingdom was the late - 2000s recession. United States Main article : List of recessions in the United States This article duplicates the scope of other articles. Please discuss this issue on the talk page and edit it to conform with Wikipedia 's Manual of Style. ( October 2013 ) According to economists, since 1854, the U.S. has encountered 32 cycles of expansions and contractions, with an average of 17 months of contraction and 38 months of expansion. However, since 1980 there have been only eight periods of negative economic growth over one fiscal quarter or more, and four periods considered recessions : July 1981 -- November 1982 : 15 months July 1990 -- March 1991 : 8 months March 2001 -- November 2001 : 8 months December 2007 -- June 2009 : 18 months For the past three recessions, the NBER decision has approximately conformed with the definition involving two consecutive quarters of decline. While the 2001 recession did not involve two consecutive quarters of decline, it was preceded by two quarters of alternating decline and weak growth. Late 2000s Main article : Great Recession Official economic data shows that a substantial number of nations were in recession as of early 2009. The US entered a recession at the end of 2007, and 2008 saw many other nations follow suit. The US recession of 2007 ended in June 2009 as the nation entered the current economic recovery. United States The United States housing market correction ( a possible consequence of United States housing bubble ) and subprime mortgage crisis significantly contributed to a recession. The 2007 -- 2009 recession saw private consumption fall for the first time in nearly 20 years. This indicates the depth and severity of the current recession. With consumer confidence so low, recovery takes a long time. Consumers in the U.S. have been hard hit by the current recession, with the value of their houses dropping and their pension savings decimated on the stock market. Not only have consumers watched their wealth being eroded -- they are now fearing for their jobs as unemployment rises. U.S. employers shed 63,000 jobs in February 2008, the most in five years. Former Federal Reserve chairman Alan Greenspan said on 6 April 2008 that `` There is more than a 50 percent chance the United States could go into recession. '' On 1 October, the Bureau of Economic Analysis reported that an additional 156,000 jobs had been lost in September. On 29 April 2008, Moody 's declared that nine US states were in a recession. In November 2008, employers eliminated 533,000 jobs, the largest single month loss in 34 years. For 2008, an estimated 2.6 million U.S. jobs were eliminated. The unemployment rate in the US grew to 8.5 percent in March 2009, and there were 5.1 million job losses until March 2009 since the recession began in December 2007. That was about five million more people unemployed compared to just a year prior, which was the largest annual jump in the number of unemployed persons since the 1940s. Although the US Economy grew in the first quarter by 1 %, by June 2008 some analysts stated that due to a protracted credit crisis and ``... rampant inflation in commodities such as oil, food, and steel, '' the country was nonetheless in a recession. The third quarter of 2008 brought on a GDP retraction of 0.5 % the biggest decline since 2001. The 6.4 % decline in spending during Q3 on non-durable goods, like clothing and food, was the largest since 1950. A 17 November 2008 report from the Federal Reserve Bank of Philadelphia based on the survey of 51 forecasters, suggested that the recession started in April 2008 and would last 14 months. They project real GDP declining at an annual rate of 2.9 % in the fourth quarter and 1.1 % in the first quarter of 2009. These forecasts represent significant downward revisions from the forecasts of three months ago. A 1 December 2008, report from the National Bureau of Economic Research stated that the U.S. has been in a recession since December 2007 ( when economic activity peaked ), based on a number of measures including job losses, declines in personal income, and declines in real GDP. By July 2009 a growing number of economists believed that the recession may have ended. The National Bureau of Economic Research announced on 20 September 2010 that the 2008 / 2009 recession ended in June 2009, making it the longest recession since World War II.

( February 2008 ) Many other countries, particularly in Europe, have undergone negative GDP growth. Some countries have been able to avoid a recession but have still experienced slower economic activity, such as China. India and Australia were able to maintain positive growth throughout the late - 2000s recession. China had their stock market crash, which began with the popping of the stock market bubble on 12 July 2015.
