Difference between the growth rate of
Explanation of Solution
GDP measures the value of all final goods and services produced by an economy in an accounting year.
It is given that the economy of countries A and B grow at an annual rate of 3 percent and 4 percent respectively. And the two countries start with a similar GDP.
The growth rate after 25 years can be calculated using the following formula-
Here,
FV represents the
PV represents the present value of GDP
t represents the total number of years
Assuming, the GDP of both countries equal to $10 at the initial stage. Plug the given values in (1) to determine the value of the GDP of both the countries after 25 years.
Country A
Thus, the future value of country A's GDP is equal to $20.094.
Country B
Thus, the future value of country B's GDP is equal to $26.65.
After 25 years, country B's economy is larger than country A by the following proportion,
Thus, country B's economy is approximately 27% higher than country A. The answer is not 25% because the rate at which the economy is growing is compounding.

How much larger (in percentage terms) is this country if its growth rate is 4.33% instead of 3.13% after 36 years of growth? Answer this as a percentage and round your answer to two digits after the decimal without the percentage sign. ex. If you found the rate to be 5.125%, answer 5.13.arrow_forward
