I left Delhi, in 1971, shortly after Collective Choice and Social Welfare was published in 1970.

The educational excellence of Presidency College was captivating. My interest in economics was amply rewarded by quite outstanding teaching.

The curriculum of the school did not neglect India's cultural, analytical and scientific heritage, but was very involved also with the rest of the world.

People's identities as Indians, as Asians, or as members of the human race, seemed to give way - quite suddenly - to sectarian identification with Hindu, Muslim, or Sikh communities.

It is also very engaging - and a delight - to go back to Bangladesh as often as I can, which is not only my old home, but also where some of my closest friends and collaborators live and work.

I was born in a University campus and seem to have lived all my life in one campus or another.
