In economics, a recession is a business cycle contraction, a general slowdown in economic activity. During recessions, many macroeconomic indicators vary in a similar way. Production, as measured by gross domestic product (GDP), employment, investment spending, capacity utilization, household incomes, business profits, and inflation all fall, while bankruptcies and the unemployment rate rise.
Recessions generally occur when there is a widespread drop in spending, often following 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.
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
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 decrmed L-shaped.
Psychological aspects
Recessions have psychological and confidence aspects. For example, if the expectation develops that economic activity will slow, firms may decide to reduce employment levels and save money rather than invest. Such expectations can create 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 pe
ople."
Balance sheet recession
The bursting of a real estate or financial asset price bubble can cause a recession. 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.
Liquidity trap
A liquidity trap situation can develop in which interest rates reach near zero (ZIRP) 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.
Government responses
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 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, will work when monetary policy fails. Spending is more effective because of its larger multiplier but tax cuts take effect faster.
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 DJIA 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 when a recession 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.
Impacts
Unemployment
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 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. a
