Recession? Depression? What's the difference?Before the Great Depression of the 1930s any downturn in economic activity was referred to as a depression. The term recession was developed to differentiate periods like the 1930s from smaller economic declines that occurred in 1910 and 1913. A depression is simply a recession that lasts longer and has a larger decline in business activity.
A good rule of thumb for determining the difference between a recession and a depression is to look at the changes in Gross National Product. A depression is any economic downturn where real Gross Domestic Product declines by more than 10 percent.
Gross Domestic Product (GDP) is the total amount of goods and services produced in the United States in a year and is calculated by adding together all final market values.By this yardstick, the last depression in the United States was from May 1937 to June 1938, where real GDP declined by 18.2 percent.
The Great Depression of the 1930s was actually two separate events: an incredibly severe depression lasting from August 1929 to March 1933 where real GDP declined by almost 33 percent, followed by a period of recovery and another less severe depression of 1937-38. The United States hasn’t had anything even close to a depression in the post-war period. The worst recession in the last 60 years was from November 1973 to March 1975, where real GDP fell by 4.9 percent.
Data Trends
Following the 2001 recession, growth in real GDP increased in 2002, 2003, and 2004, reaching 3.9 percent in 2004. The annual rate of growth decreased slightly in 2005 and 2006 to 3.2 and 3.3 percent respectively. Growth in the first quarter of 2006 was rapid and slowed in the second, third, and fourth quarters 0f 2006. The rate of growth in the first quarter of 2007 is the lowest since the fourth quarter of 2002.
The rate of growth over the last twelve months has been slightly under 2 percent, the slowest of any twelve-month period since the end of 2002 and beginning of 2003. The actual rates for the last three quarters of 2006 were 2.6, 2.0, and 2.5 percent
The causes of the slowdown over the last twelve months are the lagged effects of a restrictive monetary policy (See the latest FOMC case study.), the lagged effects of the slowing growth in prices of homes and importance of that change for consumption spending, and a slowdown in investment spending on the part of businesses.
The particular slowing of growth in the first quarter comes from what are likely temporary factors. Businesses have reduced inventory investment during the quarter and that is viewed as a positive sign for future spending on the part of businesses. Even though we should remember that this is just one quarter of a year, growth this slow should be of some concern.
