Abandon inflation targeting while we still have time
Back in 2012, I wrote a piece arguing that Australia should abandon the policy of inflation rate targeting, and switch to one in which the target was the level of nominal GDP. As I argued then, inflation targeting is part of a package deal involving a number of propositions, most particularly
* Macroeconomic management should be left to an independent central bank
* Successful inflation targeting will also stabilize real GDP, and therefore fulfil the dual mandate of price stability and full (or as full as possible) employment
* The best policy approach for central banks involves modest regular adjustments of a key interest rate. In Australia this is the cash rate, which is the overnight money market interest rate.
The idea of nominal income targeting has recently been put forward by .Nick Xenophon and economist Danny Price, in relation to the contract with the new Governor of the Reserve Bank, Phil Lowe. The article mentions my support, and I commented on an earlier draft.
Writing in Crikey, Bernard Keane and Glenn Dyer criticise the idea, making three points
(a) Unlike other countries, we are not yet at the zero lower bound, so we can continue using interest rate policy
(b) Macroeconomic outcomes in Australia have been pretty good under inflation targeting
(c) A nominal GDP target can’t be achieved using monetary policy alone, we need fiscal policy as well.
My response to point (c) is “Yes, that’s the point of the shift. When we dump inflation targeting, we dump the entire package, including exclusive reliance on monetary policy”. On (a) and (b), it seems to me more sensible to make the change when we can, rather than be in the position of most countries, where inflation targeting remains notionally in force, but in practice the only instrument available is open market security purchases (aka quantitative easing). And in all those countries, macro outcomes in the inflation targeting era have ranged from poor to disastrous.
Although Australia is doing well right now, interest rates are heading down, and would certainly hit zero fast in the event of a crisis. So why not fix our policy now, while we still have time.
