Economics GDP and the Business Cycle

Gross domestic product (GDP) is the economic measure which quantifies the production within a country's economy in a single period of time. The measure, which is usually on an annual or a quarterly basis, is usually calculated as the total market value of all the finished goods and services that country during the period (Nellis and Parker, 2000). In 2012 the GDP in the U.S. had reached $15,094 billion dollars, an increase on the 2011 figure of $14,582.4 billion (Trading Economics, 2013). This in turn was an increase on 2010, when the GDP was $14,043 billion. This would appear to indicate a growing economy, where there is an increase in output. However, this is the market value on current prices, each year the increase includes inflation, so the real growth, that is the actual growth less an allowance for inflation, is a better measure of how an economy is performing. Even without allowing for inflation it is possible to see that while there appears to have been a period of growth, 2010 was not a growth year, as the GDP figure reflected a fall, as 2009 had a higher GDP of $14,296.9 billion (Trading Economics, 2013). Historically the U.S. economy tends to grow at a mean of approximately...

This reflects what is known as the business cycle, a cycles where there are periods of growth or expansion and periods where the economy slows down or contracts. The GDP is the primary indicator of the stage in the business cycle that a country is experiencing.
There are four stages to the business cycle; these are an economic contraction, an economic trough, an economic expansion and an economic peak. The U.S. economy shows these different cycles, to appreciate what they are each of the business stages can be considered and then a graph may be used to show where they have occurred. The first stage mentioned was that if an economic contraction. During the economic contraction there is a slow down in the rate of growth, where the GDP for the period, will still show an increase, but the increase will be less than in pervious periods. The slow down of growth reflects a decreasing level of demand in the economy, which may start a negative cycle;…
