The year was 1971. The place Delhi School of Economics, which was undergoing a major upheaval.
Amartya Sen, who taught welfare economics and social choice theory, had just left for London School of Economics. So had Manmohan Singh, who taught international trade theory, for commerce ministry. So, too, had Arjun Sengupta who taught economic policy.
Into the breach left by Sen and Singh walked a 28-year old, ex-student of Sen. He had done both his MA and PhD at DSchool, as it is called, and then gone off abroad somewhere.
His name, we were told, was Prasanta Pattanaik. He was shy and self-effacing.
