I would argue that these revisions to u* and r* indicate that the FOMC has been data dependent in this second sense and that these updated assessments of u* and r* have had an important influence on the path for the policy rate actually implemented in recent years.
Indeed, had the Fed not been data dependent in this second sense and remained closed to the possibility that the economy had changed and historical estimates of r* and u* needed to be revised, that stubbornness would have represented a material policy mistake. In addition to u* and r*, an important input into any monetary policy assessment is the state of inflation expectations.
