Stanley has already been all over IPAB, but I wrote a column about it today. Thanks to Michael Cannon of the Cato Institute who drew my attention to this very apt Hayek quote:

Parliaments come to be regarded as ineffective ‘talking shops,’ unable or incompetent to carry out the tasks for which they have been chosen. The conviction grows that if efficient planning is to be done, the direction must be taken ‘out of politics’ and placed in the hands of experts — permanent officials or independent autonomous bodies.
