India’s Green Revolution is a

dramatic example of how the input

of greater knowledge in the form of

improved production technologies can

rapidly increase the productivity of

scarce land resources. India’s IT

revolution is a striking instance of

how the importance of human capital

has come to acquire a higher position

than that of material, plant and

machinery.
