Identifying Quantitative and Qualitative Monetary Policy Shocks
This paper proposes a novel method for identifying quantitative and qualitative monetary policy shocks in central bank's balance sheet operations. Compared with existing identification methods, our method is agnostic and flexible in that it does not assume the way of response of two balance sheet instruments, namely, the size and composition of the central bank's balance sheet, after the bank makes policy decisions. Under some restrictions imposed in the vector autoregressive model, we identify the two unconventional policy shocks as "anticipated" shocks that best portend the current and future paths of the unconventional policy indicators in response to the policy shocks. We observe in a robust manner that the qualitative easing shocks have expansionary effects on the real economy, while the quantitative easing shocks do not.
