UPSC Prelims 2018 GS Paper I · Q50 of 100 Economy medium

Despite being a high saving economy, capital formation may not result in significant increase in output due to

  1. (a) weak administrative machinery
  2. (b) illiteracy
  3. (c) high population density
  4. (d) high capital-output ratio ✓ UPSC's answer

Why the answer is (d)

• The capital–output ratio (ICOR) measures how much capital is needed to produce one additional unit of output.

• A high capital–output ratio means investment is inefficient — much capital yields little output — so even a high-saving economy sees little growth from its capital formation (Harrod–Domar: growth = savings rate ÷ ICOR) — option (d).

• Weak administration (a), illiteracy (b) and population density (c) may affect efficiency but are captured in economics through the ICOR.

• Hence option (d).

Why the other options are wrong

(a) weak administrative machinery
Administrative weakness is not the economic explanation.
(b) illiteracy
Illiteracy is not the direct link between capital and output.
(c) high population density
Population density does not determine capital productivity.
