During a visit to the hallowed halls of the Finance Ministry not very long ago, KV Subramanian and his wife were admiring the names of the illustrious economists carved on a big brown board in one of the more spacious offices of North Block in the capital. In 2018, the couple came back, but this time, it was his name that was being engraved on the board as India’s chief economic adviser. Subramanian now is the youngest to have achieved that distinction.
