ms. mester: i do agree with that.t case for a while that we really need to be moving interest rates up gradually given where the economy is. growth is at a sustainable pace. labor markets continue to improve. inflation is below target, no doubt, but it is on a path to moving up gradually at 2%. we have been at interest rates that are very low for quite a while. it just makes sense to start bringing it up gradually. of course, we respond to data as it comes in, and as the outlook changes, we would change off of that. but the strategy of moving interest rates up, relative to where economy is or where it has been or relative to our goals makes sense to me. remember, monetary policy has to be preemptive. i don't have concerns about moving interest rates up given how low it is, even though we have not hit 2% inflation yet. michael: but in the last two days, governor powell and chair yellen both said there is a possibility our inflation models are wrong, and we will not see it rise to 2%. how much credence to you give that?
