A Plan sets a target GDP growth rate of 6% per annum. If the economy's incremental capital-output ratio (ICOR) is 4, what must be the required investment rate (investment as a percentage of GDP) to achieve the target?

The required investment rate is 24% of GDP. Since ICOR equals the investment rate divided by the growth rate, the investment rate equals ICOR multiplied by growth, which is 4 times 6 percent. Dividing growth by ICOR, giving 1.5%, would be incorrect.

  1. A24%Correct
  2. B1.5%
  3. C10%
  4. D20%

Explanation

ICOR = Investment rate / Growth rate, so Investment rate = ICOR x growth rate = 4 x 6% = 24%. Check: 24% / 4 = 6%. The 1.5% option comes from dividing 6 by 4, which inverts the relationship.
