let's bring in randy crosner with the yirnt of chicago booth consume of business.elcome back. >> they needed to do this and needing to raise rates through the year so i think finally on the right path if question is, is it going to be enough? little bit too late? inflation is already obviously gotten into the system. >> you're in the same camp that we might find larry summers and opposite from the market practitioners on the panel what would you say who say the fed is making a mistake here >> it is important that inflation expectations don't get out of control and these disruptions associated with the war in the ukraine, with the lockdowns in china that are going to disrupt supply, that's out of the fed's direct control and doesn't mean they shouldn't respond to it. people don't care about the source prices going up they demand higher wages and if the fed doesn't do anything about it they say the fed doesn't care and even higher wages from inflation from under 2 to 8 and could go to 10. >> randy, how does the fed thread the needle and go from maybe behind the curve
