What is a Recession?

In economics, a recession is a contraction in the business cycle. There is a decline in economic activity, which we measure using several macroeconomic indicators.

In recessions, the following factors drop: GDP (gross domestic product), investment spending, household income, inflation, and business profits. There is also an increase in bankruptcies and the unemployment rate.

An adverse demand shock, an external trade shock, an economic bubble burst, or a financial crisis are possible causes of recessions. Economists say that if we do nothing to address banks’ reluctance to lend money, recessions get worse or last longer.

Recession
Keynesian economists say that if there is a recession, the government should intervene to boost economic activity. Otherwise, the economy can remain flat and fragile for a long time.

When governments detect signs of a slowdown, they usually start off by increasing the money supply and decreasing taxation. They may also boost government spending.

There are various definitions of what recessions are. Some economists believe that they occur when there has been a 1.5% rise in unemployment in the past year.

National Bureau of Economic Research (NBER) defines the term 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.”

In the European Union defines the term as two successive quarters of GDP contraction. This definition is, in fact, gaining traction across the world.

Forecasting a recession

There are no definite ways of accurately predicting when recessions occur. However, there are few indicators that economists measure.

If economists detect recessionary signs, they can subsequently warn their government, central bank, and other stakeholders. Some of the indicators include:

– An inverted yield curve.

– A three-month drop in the employment rate.

– Index of Leading (Economic) Indicators.

– Assets substantially drop in price. Property prices and the value of financial assets, especially, are more likely to point to potential economic consequences.

In addition to the indicators above, severe stock market declines may precede recessions.

Jeremy J. Siegel stated that since 1948, there have been ten recessions that followed stock market declines. Siegel is Professor of Finance at the Wharton School of the University of Pennsylvania in Philadelphia. He is the author of Stocks for the Long Run.’

A double-dip recession is one that experiences recovery and then dips straight back into another recession. It occurs when an initial recovery fails. In other words, the recovery does not manage to gain back total economic output. The economy subsequently slides back into decline.

According to ft.com/lexicon, a recession is:

“A marked contraction in economic activity. There is little agreement on a definition, but a recession is often associated with at least two consecutive quarters of declining GDP or the verification that one exists by an august body such as the National Bureau of Economic Research in the US.”

“A global recession is often thought to be a situation when global GDP growth falls below 2 percent.”

The Great Depression and the Great Recession

The Great Recession followed the global financial crisis of 2007/8 and the subprime mortgage crisis of 2007-2009.

In the 1930s, many countries’ economies deteriorated during the Great Depression. From 1929 to 1932, global GDP shrank by 15%.

Depressions are much more severe and longer-lasting than recessions.

When a country is in a recession, the central bank may try to kick-start the economy by injection money into the private banking system. However, sometimes the measure does not work. We call this situation a liquidity trap.

Even though banks offer loans at very low interest rates, people still want to hoard cash. In fact, during a liquidity trap, very few people want to borrow or spend more.

When a recession affects many countries in different parts of the world, we call it a Global Recession.
