自由選擇
When Milton Friedman visited India in 1963, Pai was responsible for his meetings in India. The friendship generated during this visit lasted till Pai's death. When the Friedmans published their book "Free to Choose" in 1982, an autographed copy was sent to Pai, with an offer to publish any portion as a booklet. The Forum obliged them by bringing a booklet "Central Economic Planning" in September 1982.
