Gross Domestic Product
The statistic used to measure the United States economy is called the Gross Domestic Product (GDP). The GDP is defined as the “total market value of final goods and services produced within an economy in a given year” (O'Sullivan, Sheffrin, & Perez, 2008, pg. 102). There is the measurement of the nominal GDP, which is the value of the GDP in current dollars, and there is the real GDB, “which is a measure of GDP that controls for changes in prices” (O'Sullivan et al.). The Bureau of Economic Analysis (BEA), generally uses the real GDP when reporting the annual GDP for comparison because it is more accurate. The BEA makes three essential distinctions as they calculate the real GDP:

There are three important ways in which the real GDP affects the United State’s economy. The most significant is that it is used to verify the pace at which the U.S. economy is growing. Is it growing faster, slower, or is it remaining the same as the previous quarter. The GDP is also used to compare the size of other economies throughout the world. It is also used to compare the relative growth of other economies in the world. Investors may use the GDP growth report when making decisions on how to allocate their assets and where there are good business opportunities. The Federal Reserve also uses the GDP growth rate to see if restraint or stimulation is needed for the economy (Amadeo, 2007). Calculation GDP Values for 2004 & 2005 Using a simple Economy
