Subramanian who is specialised in economic growth and intellectual property rights criticised the Indian Government's decision to derail a WTO deal struck last year. He had said that India should not opposed to the pact (WTO) and revisit the issue at WTO in the near future.
Not only this, Subramanian also criticised Jaitley's first budget for being too optimistic in its revenue forecasts.
According to reports, Modi himself handpicked Arvind Subramanian to be his chief economic adviser. As per analysts, one of the prime factors that tipped scales in his favour was his proximity to RBI governor Raghuram Rajan.
The post of chief economic advisor fell vacant after Rajan was appointed as governor of the central bank in September last year.
Subramanian has served as a senior fellow at Peterson Institute for International Economics and at the Center for Global Development in US. He has worked with International Monetary Fund as an assistant director in research department.
