Yes, I agree it is a good contrary case to consider.
My understanding is that an explicit target really hits it home. It makes things legal. It gives people the ability to plan things around it. Did the BOE draw a line the way the swiss central bank did at 1.2 CHF to EUR and should out "You will not Pass"? If it did and still this happened, I would be quite surprised.
You can check out Lars Christensen and Scott Sumner's posts on Britain, as I will do the same.
As an aside, I myself live in a country (India) where nominal GDP growth is there, but practically nothing else for a healthy economy is there. I have no illusions that without serious regulatory and fiscal reform, India would not achieve the results of a good economic system - Supply side issues, not so much demand side.
Thanks for your interesting reply. I've read lots of Sumner (and to a lesser extent Christensen) but their discussion of Britain is fleeting at best.
How do you draw a line in the sand and say "you shall not cross" when it comes to NGDP? That is the whole question. If you are defending a currency peg, you have a clear policy tool (forex purchases) and you can see the effects of your interventions in an actively traded market. The SNB can check the CHF:EUR exchange rate at any time, and intervene in the market to sell CHFs and buy EURs as necessary...
The last thread didn't fare too badly, I think; let's make it a monthly tradition. (Me, I'm more interested in thinking about real-world policies or philosophies, actual and possible, rather than AI design or physics, and I suspect that many fine, non-mind-killed folks reading LW also are - but might be ashamed to admit it!)
Quoth OrphanWilde:
Let's try to stick to those rules - and maybe make some more if sorely needed.
Oh, and I think that the "Personal is Political" stuff like gender relations, etc also belongs here.
