Rethinking ‘Data‑Driven’: Why Friedman’s Long‑View Philosophy Matters Again

Slightly more than a week before a critical Federal Reserve interest rate meeting, the outlook on prices has been muddied once again by uncertainty over tariffs. Potential fiscal policy actions involving credit card rate caps, oil price manipulation, or home buyer subsidies have also been disruptive. The best way for monetary policy authorities to think about assessing the risks to price stability may be to embrace the reality that the much-desired steady state of data reliability and predictable policy is simply not going to happen. Stepping away from being “data driven” would potentially put the Federal Reserve on a path of Miltonian simplicity, as in Milton Friedman and his basic premise that monetary policy should not attempt to micromanage short-term economic developments. In such a world, the Federal Reserve would simply ensure that the money supply was appropriate for a long-range equilibrium growth rate of 2.5% — very close to where the US is at the moment. Of course, the problem is that Friedman is long gone from the scene, and there are none of his acolytes currently in the corridors of executive power. Friedman’s ideas are somewhat captured in the debate over the neutral or natural rate of interest, aka R*, yet this debate is really only playing out in academic circles and at the Federal Reserve. Friedman’s views were not without controversy during his lifetime, but one suspects that there may be more than a few converts now at the Fed to his perspective on what he would have deemed the fool’s errand of chasing monthly data in this environment.
