GDP is important in macroeconomics as it measures the total final goods and services produced in a country. Real GDP is more accurate as it accounts for inflation. GDP can indicate economic booms and recessions, and is used by investors to assess the state of an economy.
The role of gross domestic product (GDP) in macroeconomics can be seen in the importance of GDP in assessing the state of an economy. GDP is an important component of macroeconomics that measures the total final goods and services produced in a country within a given period, usually on a quarterly basis. This role of GDP in macroeconomics is important because an analysis of the pattern of GDP collected over a given period will allow stakeholders such as governments, organizations and individuals to understand the business cycle behavior for that region.
GDP is divided into real GDP and nominal GDP. An understanding of the two concepts will further establish the role of GDP in macroeconomics. Nominal GDP is a number that does not take into account the effect of inflation. Real GDP is adjusted to take inflation into account. As such, real GDP is real GDP, as opposed to nominal GDP, which can be misleading to potential investors and other parties who use it as a yardstick to measure the state of the economy.
Real GDP is the basic factor to be studied when considering the role of GDP in macroeconomics. This is because any decision stemming from the GDP assessment must be based on real GDP for greater accuracy. An assessment of real GDP allows governments to measure the state of their countries’ economies. An increase in GDP can be seen as positive if it is done in a moderate and sustained manner. GDP numbers must also maintain a balance that economists find desirable for a nation’s economy.
When GDP rises too sharply to a higher than preferred level, it can lead to an economic boom period characterized by increased consumer confidence and excessive spending. This period of overspending can lead to inflation, especially since demand is often greater than supply during these periods. This role of GDP in macroeconomics is important because these periods of intense and unsustainable economic activity often indicate to economists and other investors that a recession may not be too far away.
Another role of GDP in microeconomics is based on the fact that GDP numbers are used by investors to assess the state of a country’s economy before making any investment decisions. Most organizations include an assessment of quarterly GDP numbers in their environmental and market analysis. Others depend on it for making various financial decisions and for preparing their periodic financial reports.
