I’m not sure what you mean… “did the lop work for them”?
Korea just lopped last week.
Venezuela lopped Jan 2008.
Did it work?? Let’s start from the beginning. A country starts with a reasonable amount of money to support their economy. They have bills like a 1, 5, 10, 20 and a 100. They adopt poor financial policies and inflation starts to rage. Instead of changing policies, a lot of countries answer by flooding the market with more money, which fuels higher inflation, which they answer by printing more, until they have to print 1000, 5000, 10000, 25000 unit bills to try and keep up… and they end up with money supply numbers in the TRILLIONS.
A lop serves one function… it is to return the money supply to a reasonable number, Billions… and allow them to print smaller denominations again.
So in that respect… yes… every lop works. It reduces money supply to a reasonable level.
That doesn’t guarantee that inflation wont destroy the new lopped currency also. That’s why countries try to wait until inflation is under control before lopping.
