Interest rate control and the transmission of monetary policy
We study how short-term interest rate volatility affects the transmission of monetary policy. To identify exogenous changes in volatility, we exploit the pronounced heteroskedasticity visible in the time-series of euro area short-term rates over the past two and a half decades. Interacting the exogenous variation in volatility with high-frequency-identified monetary policy shocks, we find that increases in volatility dampen the effects of monetary policy on output and prices.
