Responding to the letter by 108 economists raising concerns over the validity of statistical data, Finance Minister Arun Jaitley said that the majority of them are \u2018compulsive contrarians\u2019. It comes a day after 131 Chartered Accountants came forth to counter the allegations over political interference influencing data quality. "A few days ago 108 so called economists issued a statement questioning its validity. I analysed the credentials of all 108 economists and found out that 70% of those are compulsive contrarians, critics of the government who have signed multiple memorandums against this government in the last five years. Most of these memorandums are on the issue of politics and not economy\u201d, he said in a video posted on his Twitter account.

"As against this, credible international institutions like IMF and World Bank have always accepted our data. So two campaigns are on. Well the Indian economy hasn't created jobs - a myth. Our infrastructure growth has been the fastest\u201d, Arun Jaitley also said. He further said that at a time when the incumbent government is working on a large scale on building infrastructure, such a campaign claiming there are no jobs is incorrect.
