Word has it that World Bank economists use "obviously fabricated" data from time to time. These are not Sitaram Yechury or Medha Patkar’s words, but those of Paul Romer, former chief economist of the World Bank, in a recent email exchange reported by Financial Times. Romer retracted them later, but this "may not end the controversy", as The Economist mildly put it. This not the first time that World Bank economists skate on thin ice. Another recent example concerns the widely-quoted estimate of $11 billion annual savings (or potential savings) due to Aadhaar
