A propos our topic du jour, here is former Federal Reserve Chairman Paul Volcker:

I recently commented to some of my economist friends that I’m not
aware of any large contribution that economic science has made to
central banking in the last 50 years or so.

Our ability to forecast is still very limited. The old issues of the
relative role of fiscal and monetary policies are still debated.
Markets are certainly more complex, and some of the old approaches
toward monetary control seem less relevant. Recent events have
certainly illustrated limitations in our understanding of the economy.
