Neo-Fisherian Policies Impart Unavoidable Instability

My colleagues have a new paper on interest rate pegs in New Keynesian models:

Interest Rate Pegs in New Keynesian Models by George W. Evans and Bruce McGough Abstract: John Cochrane asks: "Do higher interest rates raise or lower inflation?" We find that pegging the interest rate at a higher level will induce instability and most likely lead to falling inflation and output over time. Eventually, this will precipitate a change of policy. ...
Conclusions: Following the Great Recession, many countries have experienced repeated periods with realized and expected inflation below target levels set by policymakers. Should policy respond to this by keeping interest rates near zero for a longer period or, in line with neo-Fisherian reasoning, by increasing the interest rate to the steady-state level corresponding to the target inflation rate? We have shown that neo-Fisherian policies, in which interest rates are set according to a peg, impart unavoidable instability. In contrast, a temporary peg at low interest rates, followed by later imposition of the Taylor rule around the target inflation rate, provides a natural return to normalcy, restoring inflation to its target and the economy to its steady state.
