This paper investigates the evolution of the monetary policy in Peru between 1996Q1 and
2016Q4 using a mixture innovation time-varying parameter vector autoregressive model
with stochastic volatility (TVP-VAR-SV)model proposed by Koopetal.(2009).The
main empirical results are:(i)VARcoe¢cients and volatilities change more gradually than
covariance errors overtime;(ii)the volatility of monetary policy shocks is higher during
pre-In ation Targeting (IT) regime;(iii)a surprise increase in the interest rate produces
GDP growth falls and reduces in ation in the longrun;(iv)the interest rate reacts more
quickly against aggregate supply shocks than aggregate demand shocks;(v)monetary
policy shocks explain a high percentage of domestic variables during pre-IT regime and
then,their contribution decrease during IT-regime.
