I had the pleasure last week of attending the conference on
Central Bank Governance And Oversight Reform at Hoover, organized by John Taylor.
Avoiding the usual academic question of what should the Fed do, and the endless media question will-she-or-won't she raise rates, this conference focused on
how central banks should make decisions. Particularly in the context of legislation to constrain the Fed coming from Congress, with financial dirigisme and "macro-prudential" policy an increasing temptation, I found these moments of reflection quite useful.
Some of the issues: Should the Fed follow an "instrument rule," like the Taylor rule? Should it have "goal," like an inflation target, but then wide latitude to do what it takes to attain that goal? What structures should implement such a rule? Implicit in a rule that the Fed should do things, like target inflation and employment, is an implicit rule that it should ignore others, like asset prices, exchange rates and so on. (I think this is much too often overlooked. As financial reform should start by delineating what is
not systemic, and hence exempt from regulation, monetary policy rules should start by saying what the Fed should
ignore.) Should that limitation be more explicit? What's the right governance structure? Should we keep the regional Feds? How should Fed meetings be conducted? Is "transparency" the enemy of productive debate? How much discretion can an agency have while remaining independent? And so on.
I was going to post thoughts on he whole conference, but
John Taylor just posted an excellent summary, so I'll just point you there.
My job was to discuss Paul Tucker's (ex Deputy Governor of the Bank of England) thoughtful paper, "
How Can Central Banks Deliver Credible Commitment and be “Emergency Institutions" Paul's paper starts to think deeply about independent regulatory agencies in general, and monetary and fiscal policy together. My discussion is narrower. I'll pass on the discussion (

Comments on “How Can Central Banks Deliver Credible Commitment and be “Emergency Institutions” By Paul Tucker
May 21 2015
Let me start by summarizing, and cheering, Paul’s important points.
The standard view says that perhaps monetary policy should follow a rule, but financial-crisis firefighting needs discretion; a big mop to clean up big messes; flexibility to “do what it takes”; “emergency” powers to fight emergencies.
I think Paul is telling us, politely, that this is rubbish. Crisis-response and lender-of-last-resort actions need rules, or “regimes,” even more than monetary policy actions need rules. At a basic level any decision is a mapping from states of the world to actions. “Discretion” just means not talking about it.
More deeply, you need rules to constrain this mapping, to pre-commit yourself ex-ante against actions that you will choose ex-post, and regret. Monetary policy rules guard against “just this once” inflations. Lender of last resort rules guard against “just this once” bailouts and loans.
But you need rules even more, when the system responds to its expectations of your actions. And preventing crises is
all about controlling this moral hazard.
