New York – The World’s central bankers are a close-knit club, given to fads and fashions. In the early 1980’s, they fell under the spell of monetarism, a simplistic economic theory promoted by Milton Friedman. After monetarism was discredited – at great cost to those countries that succumbed to it – the quest began for a new mantra.
The answer came in the form of “inflation targeting,” which says that whenever price growth exceeds a target level, interest rates should be raised. This crude recipe is based on little economic theory or empirical evidence; there is no reason to expect that regardless of the source of inflation , the best response is to increase interest rates. One hopes that most countries will have the good sense not to implement inflation targeting; my sympathies go to the unfortunate citizens of those that do. (Among the list of those who have officially adopted inflation targeting in one form or another are: Israel, the Czech Republic, Poland, Brazil, Chile, Colombia, South Africa, Thailand, Korea, Mexico, Hungary, Peru, the Philippines, Slovakia, Indonesia, Romania, New Zealand, Canada, the United Kingdom, Sweden, Australia, Iceland, and Norway.)
