In my post on neutral interest rates I mentioned productivity figures. I wondered whether the reason the estimate of the (real) neutral interest rate of 1.8% (which is implausibly high) is a function of (i) using the wrong productivity measure; (ii) the problems with UK productivity measures. Labour market productivity is released each quarter, but ideally we want to use MFP.

The closest I've come is a January 2014 ONS estimate of MFP. It's labelled "experimental" but at least provides annual data from 1997-2012. It looks like this:

If anyone is aware of quarterly estimates, I'd be interested to know.
