Fed's Interest Rate Policy Neutralized, Solution Lies in Longer Loans.
The Taylor Rule's Zero Lower Bound issue can be fixed by setting interest rates on longer-term loans than the current 6 weeks. Lowering the cost of excess reserves to zero has canceled out the Fed's efforts to stimulate the economy. Removing interest on excess reserves would make monetary policy effective again, but it would mean undoing the Fed's Quantitative Easing. In the Taylor Rule, inertial terms should be avoided, and the "output gap" might not be a reliable indicator. The unemployment gap is more useful, but its direct inclusion in the Taylor Rule is debatable.
