Striving for Economic Growth
Read this explanation of the United States economy and its relationship to the GDP. The combination of expansion and contractions is called the business cycle. The United States GDP has had slow, steady growth, allowing citizens to have a high standard of living. Over the last two decades, China's GDP has been growing much faster than most other countries.
Perhaps the most important way to judge a nation's economic health is to look at its production of goods and services. The more the nation produces, the higher its standard of living. An increase in a nation's output of goods and services is economic growth.
The most basic measure of economic growth is the gross domestic product (GDP). GDP is the total market value of all final goods and services produced within a nation's borders each year. The Bureau of Labor Statistics publishes quarterly GDP figures that can be used to compare trends in national output. When GDP rises, the economy is growing.
The rate of growth in real GDP (GDP adjusted for inflation) is also important. Recently, the U.S. economy has been growing at a slow but steady rate of between 3 and 4 percent annually. This growth rate has meant a steady increase in the output of goods and services and relatively low unemployment. When the growth rate slides toward zero, the economy begins to stagnate and decline.
One country that continues to grow more rapidly than most is China, whose GDP has been growing at 6 to 7 percent per year. Today few things in the global marketplace are not or cannot be made in China. The primary contributor to China's rapid growth has been technology. For example, most tablets and laptops are manufactured in China.
The level of economic activity is constantly changing. These upward and downward changes are called business cycles. Business cycles vary in length, in how high or low the economy moves, and in how much the economy is affected. Changes in GDP trace the patterns as economic activity expands and contracts. An increase in business activity results in rising output, income, employment, and prices. Eventually, these all peak, and output, income, and employment decline. A decline in GDP that lasts for two consecutive quarters (each a three-month period) is called a recession. It is followed by a recovery period when economic activity once again increases. The most recent recession began in December 2007 and ended in June 2009.
Businesses must monitor and react to the changing phases of business cycles. When the economy is growing, companies often have a difficult time hiring good employees and finding scarce supplies and raw materials. When a recession hits, many firms find they have more capacity than the demand for their goods and services requires. During the most recent recession, many businesses operated at substantially lower than capacity. When plants use only part of their capacity, they operate inefficiently and have higher costs per unit produced. Let's say that Mars Corp. has a huge plant that can produce one million Milky Way candy bars a day, but because of a recession Mars can sell only half a million candy bars a day. The plant uses large, expensive machines. Producing Milky Ways at 50 percent capacity does not efficiently utilize Mars's investment in its plant and equipment.
