Q. India’s first five-year plan was based on which of the following models?

1. Mahalanobis model
2. Feldman model
3. Harrod-Domar model
4. Leontief model

Answer: Harrod-Domar model

The first Indian prime minister, Jawaharlal Nehru, presented the First Five-Year Plan to the Parliament of India and needed urgent attention. The First Five-year Plan was launched in 1951 which mainly focused in the development of the primary sector. The First Five-Year Plan was based on the Harrod–Domar model with few modifications.

The Harrod–Domar model is a Keynesian model of economic growth. It is used in development economics to explain an economy's growth rate in terms of the level of saving and of capital. It suggests that there is no natural reason for an economy to have balanced growth. The model was developed independently by Roy F. Harrod in 1939, and Evsey Domar in 1946, although a similar model had been proposed by Gustav Cassel in 1924. The Harrod–Domar model was the precursor to the exogenous growth model.
