Do Monetary Policy Shocks Affect the Neutral Rate of Interest?
We develop a trend–cycle Bayesian vector autoregression that jointly estimates the real neutral rate of interest, 𝑟𝑡∗, and identifies monetary policy shocks. As a key innovation, the framework allows cyclical shocks, most notably monetary policy shocks, to affect the trend component of macroeconomic variables, providing a new way to assess whether transitory disturbances have persistent effects. Using external instruments, we find that contractionary monetary policy shocks reduce 𝑟𝑡∗ and lower trend GDP growth, while the model’s estimates of 𝑟𝑡∗ remain consistent ...
