Are there differences in the effectiveness of quantitative easing at the zero-lower-bound in Japan over time?

摘要

Using a time-varying parameter vector autoregression (TVP-VAR) framework with a new set of sign restrictions, we study the changing effectiveness of the Bank of Japan's Quantitative Easing policies over time. We specifically analyse the so-called Zero-Interest Rate Policy from 1999 to 2000, the Quantitative Easing Policy from 2001 to 2006, and most recently the so-called 'Abenomics' strategy.
