Measuring the Economy Growth Rate of GDP GDP is an excellent index with which to compare the economy at two points in time. That comparison can then be used formulate the growth rate of total output within a nation. In order to calculate the GDP growth rate, subtract 1 from the value received by dividing the GDP for the first year by the GDP for the second year. GDP growth rate = [(GDP 1 )/(GDP 2 ] - 1 For example, using , in year 1 Country B produced 5 bananas worth \$1 each and 5 backrubs worth \$6 each. In year 2 Country B produced 10 bananas worth \$1 each and 7 backrubs worth \$6 each. In this case the GDP growth rate from year 1 to year 2 would be: [(10 X \$1) + (7 X \$6)] / [(5 X \$1) + (5 X \$6)] - 1 = 49% There is an obvious problem with this method of computing growth in total output: both increases in the price of goods produced and increases in the quantity of goods produced lead to

Unformatted text preview: increases in GDP. From the GDP growth rate it is therefore difficult to determine if it is the amount of output that is changing or if it is the price of output undergoing change. This limitation means that an increase in GDP does not necessarily imply that an economy is growing. If, for example, Country B produced in one year 5 bananas each worth \$1 and 5 backrubs each worth \$6, then the GDP would be \$35. If in the next year the price of bananas jumps to \$2 and the quantities produced remain the same, then the GDP of Country B would be \$40. While the market value of the goods and services produced by Country B increased, the amount of goods and services produced did not. This problem can make comparison of GDP from one year to the next difficult as changes in GDP are not necessarily due to economic growth....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
