The Role of Monetary Policy in Japan: A Break in the 1990s?

Abstract

This article documents time series evidence suggesting the case for a possible structural break in the role of Japan's monetary policy during the 1990s. It uses a simple vector autoregressive framework and offers some suggestive results: While a persistent effect of monetary policy on real output is detected over the full sample of 1975–1998 and the subsample that ends in 1993, such effect disappears with the recent subsample of the 1990s. The stability analysis also provides more specified evidence that there is a break in the reduced form dynamic system in 1995. Some interpretations are offered to intuitively support these findings.
