Expert's answer

The rate of economic growth per capita in France from 1996 to 2000 was 1.9% per year, while in Korea over the same period it was 4.2%. Per capita real GDP was $28,900 in France in 2003, and $12,700 in Korea.

We use the rule of 70.

The doubling time for France’s per capita real GDP is 70/1.9 = 36.8 years, so France's GDP will double in 2040.

The doubling time for Korea’s per capita real GDP is 70/4.2 = 16.7 years, so France's GDP will double in 2020.

France’s per capita real GDP in 2045 will be 28,900*1.019^42 = $63,710.88

Korea’s per capita real GDP in 2045 will be 12,700*1.042^42 = $71490.43

We use the rule of 70.

The doubling time for France’s per capita real GDP is 70/1.9 = 36.8 years, so France's GDP will double in 2040.

The doubling time for Korea’s per capita real GDP is 70/4.2 = 16.7 years, so France's GDP will double in 2020.

France’s per capita real GDP in 2045 will be 28,900*1.019^42 = $63,710.88

Korea’s per capita real GDP in 2045 will be 12,700*1.042^42 = $71490.43
