Kevin Warsh, the nominee for the new Federal Reserve Chair, believes that upcoming productivity growth could provide the Fed with room to lower interest rates, provided that higher productivity leads to economic growth with low inflation. According to Jin10, economist Ed Yardeni also anticipates that the economy will benefit from technological advancements this decade. However, he disagrees that such outcomes would justify rate cuts. Yardeni stated, "While we share Warsh's optimism about productivity, we fundamentally differ on what this means for monetary policy." Yardeni argues that faster growth will raise the natural rate of interest, or R*, which neither stimulates nor restrains the economy. He wrote, "If the Fed lowers the federal funds rate below R*, the risk is that it could fuel financial speculation and instability."
