On Moneyness, JP Koning argues that India’s demonetization experiment could have proceeded more smoothly if bank notes had been overstamped rather than immediately withdrawn.
On Alt-M, Larry White discusses three aspects of the Indian “demonetization” experiment.
The transition from old notes blocks “honest” currency transactions, reduces income, and harms the poor who don’t have access to alternative means of payment. Because not all old notes will be redeemed, the transition into new notes will generate seignorage revenue for the government on the order of USD 40 billion, according to White’s estimates. Not all groups or industries get access to the new notes at the same time; this changes the terms of trade (Cantillon effects).
India follows suggestions to fight tax evasion by taking high denomination notes out of circulation … and introducing new ones. Until the end of the year, Indians may exchange the old banknotes against new ones, at banks or post offices, by identifying themselves. On his blog, J P Koning discusses earlier demonetization episodes in Iraq and Sweden.
India’s move does not exactly follow the well publicized suggestions currently debated. But it might work.
