Many economists remain on the fence, unsure whether the benefits of demonetization on such a scale would exceed the cost of implementation. For some, cancellation of the legal tender status for the 1,000-rupee note would have been sufficient, while some question the motive behind introduction of the 2,000-rupee bill. Some doubt if the well-intended measure was ill-timed, when the economy was going strong and hailed "a bright spot" in an otherwisedull global economy. An oft-reported quote of former RBI Governor and ex-IMF Chief Economist Raghuram Rajan suggest that he did not favor the measure. In a speech from 2014, Rajan said, "Unfortunately, my sense is the clever find ways around it. They find ways to divide up their hoard in to many smaller pieces."Rajan left his post at the RBI in September 2016. Capital Economics economist Shilan Shah said over the longer term, efforts to regularize the informal economy and to tackle corruption should deliver economic benefits, including by increasing tax revenues and boosting investor sentiment.
