Recession from WikiPedia:

In economics, a recession is a general slowdown in economic activity over a long period of time, or a business cycle contraction. 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 during recessions; bankruptcies and the unemployment rate rises.

Governments usually respond to recessions by adopting expansionary macroeconomic policies, such as increasing money supply, increasing government spending and decreasing taxation.

In a 1975 New York Times article, economic statistician Julius Shiskin suggested several rules of thumb for identifying a recession, one of which was "two down quarters of GDP". In time, the other rules of thumb were forgotten, and a recession is now often defined simply as a period when GDP falls (negative real economic growth) for at least two quarters. Some economists prefer a definition of a 1.5% rise in unemployment within 12 months.
