Last week, a group of 40 economists wrote an open letter to United Progressive Alliance (UPA) chairperson Sonia Gandhi arguing for cash transfer as a mode of delivery for the proposed National Food Security Act (NFSA). The letter was carried in detail in several newspapers including Mint. The good thing is that there is now almost a consensus, at least among economists, that whatever be the mode of delivery of subsidy, there is no space for a targeted system.
