Question

In the Harrod-Domar model, which scenario correctly characterises the instability (knife-edge) principle?

A If G > Gw, entrepreneurs find inventories depleting — they increase investment, pushing G further above Gw — a self-reinforcing boom; if G < Gw, the reverse — a self-reinforcing recession
B If Gw > Gn, the economy automatically adjusts through flexible factor prices until G = Gw = Gn
C If G > Gw, excess capacity builds up, discouraging investment and pulling G back toward Gw — the model is self-stabilising
D The knife-edge problem disappears in the long run because the saving rate s adjusts to close the gap between Gw and Gn
