6.The amount of Country A’s increase in GDP per labor hour that can be attributed to the change in capital per labor hour is closest to:
A) 2.50%. B) 3.33%. C) 5.00%. D) 1.67%. The correct answer was D) According to the “one-third” rule, at a given level of technology, a one percent increase in capital per labor hour results in a one-third of one percent increase in real GDP per labor hour. If capital labor per hour grew by 5%, then the capital growth contribution to the increase in GDP is 1.67% (1/3 x 5%). 7.If in the next year, Country A’s investment in new capital increases by an additional $0.90 per labor hour, and the level of technology remains unchanged, GDP per labor hour will increase: A) and the increase will be greater than the increase resulting from the previous decade’s $0.90 increase in investment in new capital.

D) and the increase will be less than the increase resulting from the previous decade’s $0.90 increase in investment in new capital.
