The Modi government, which promised, among other things, to root out black money, demonetised nearly 86 per cent of cash overnight. This move was taken after other measures (including the Income Declaration Scheme) were not successful. Following demonetisation, there was much criticism about its impact on economic growth, employment, prices, taxes, unaccounted incomes, vulnerable sections, informal economy etc. The scale of impact of such a massive policy is clearly an empirical issue. In the absence of that, these views were at the most anecdotal and based on conjectures; some were based on quick, but thin, surveys.
