The definition of depression and recession

A “recession” is actually well-defined.  A recession’s start and end are officially (in the US) declared by the National Bureau of Economic Research.   A “depression”, though is more subjective.  Personally I think we are now in a depression, but not one as big as the Great Depression –maybe we should call it the “little Depression” or “the newer depression”.

What is the difference between a recession and a depression?

THE word “depression” is popping up more often than at any time in the past 60 years, but what exactly does it mean? The popular rule of thumb for a recession is two consecutive quarters of falling GDP. America’s National Bureau of Economic Research has officially declared a recession based on a more rigorous analysis of a range of economic indicators. But there is no widely accepted definition of depression. So how severe does this current slump have to get before it warrants the “D” word?

A search on the internet suggests two principal criteria for distinguishing a depression from a recession: a decline in real GDP that exceeds 10%, or one that lasts more than three years. America’s Great Depression qualifies on both counts, with GDP falling by around 30% between 1929 and 1933. Output also fell by 13% during 1937 and 1938. The Great Depression was America’s deepest economic slump (excluding those related to wars), but at 43 months it was not the longest: that dubious honour goes to the one in 1873-79, which lasted 65 months.
