UPDATE: I have edited my post significantly – I misread what Scott really said. That is the result of writing blog posts very early in the morning after sleeping too little. Sorry Scott…
Scott Sumner has a blog post on who might become the next governor of Bank of Japan. Scott ends his post with the following comment:
Naturally I favor the least dovish of the three.
Note that Scott is saying “least dovish” (I missed “least” in my original post). But don’t we want a the most dovish BoJ governor? No, we want the most principled governor – or rather the governor most committed to a rule based monetary policy.
The debate over doves versus hawks is a debate among people who fundamentally think about monetary policy in a discretionary fashion. Market Monetarism is exactly the opposite. We are strongly against discretion in monetary policy (and fiscal policy for that matter).
The important thing is not who is BoJ governor – the important thing is that there are good institutions – good rules. As I have argued before – what we really want is a monetary constitution in spirit of Jim Buchanan. In that sense the BoJ governor should be replaced – as Milton Friedman suggested – by a ‘computer’ and not by the most ‘dovish’ candidate.
Market Monetarists would have been “hawks” in the 1970s in the sense that we would have argued that for example US monetary policy was far too easy and we are ‘doves’ now. But that is really a mistaken way to think about the issue. If we favour for example a 5% NGDP level target for the US today – then we would have been doves in 1974 or 1981. That would make us more or less dovish/hawkish at different times, but that debate is for people who favours discretionary monetary policies – not for Market Monetarists.
If we just want a ‘dovish’ BoJ governor then we should advocate that Prime Minister Shinzo Abe gives Zimbabwean central bank governor Gideon Gono a call. He knows all about monetary easing – and so do the central bank governors of Venezuela and Argentina. But we all know that these people are ludicrously bad central bankers. In similar fashion Janet Yellen would not be the Market Monetarist candidate for the Federal Reserve chairman just because she tends to favour monetary easing – in fact it seems like Yellen always favours monetary easing. In fact you should be very suspicious of the views of policy makers who will always be hawks or doves.
The reason that Mark Carney is a good choice for new Bank of England governor is exactly that he is not ‘dovish’ or ‘hawkish’, but that he tend to stress the need for a rule based monetary policy. That said, the important thing is not Mark Carney, but rather whether the UK government is serious about introducing NGDP level targeting or not.
Monetary policy is not primarily about having the right people for the job, but rather about having the best institutions. Obviously you want to have the best people for the job, but ultimately even Scott Sumner would be a horrible Fed governor if his mandate was wrong.
If the BoJ had a rule based monetary policy and used for example NGDP futures to conduct monetary policy then it wouldn’t matter who becomes BoJ governor – because the policy would be the same no matter what. We cannot rely on central bankers to do the ‘right thing’. Central bankers only do the right thing by chance. We need to tie their hands with a monetary constitution – with strong rules.
Forget about “hawks” and “doves” – what we need is a “monetary constitution”
NGDP targeting is not about ”stimulus”
NGDP targeting is not a Keynesian business cycle policy
