• Incremental Capital Output Ratio (ICOR) measures additional capital needed.
  • It shows how much additional capital is required to produce one additional unit of output.
  • Formula: ICOR = (Change in capital / Change in output).
  • It represents how efficiently new capital is used.
  • A lower ICOR means more efficient use of new capital.
  • Investment % in GDP = ICOR x % change in GDP.
  • A lower ICOR allows for higher economic growth with less investment.
  • Or, it can achieve the same growth with less investment.
  • ICOR depends on governance, labor quality, education, skills, and technology.
