The Japanese government has pinned its hopes of defeating deflation on monetary policy. This article applies a new analytical technique, reiterative truncated projected least squares, (RTPLS) to monthly Japanese data from January 1970 to January 2003. In this application, RTPLS produces a separate estimate of dCPI/d(M2 + CD) and of dCPI/d(M2 + CD) for each observation, which makes it possible to see how they change over time due to the influence of omitted variables. I find that dCPI/d(M2 + CD) falls by 55 percent between October 1997 and January 2003, hampering the Bank of Japan's efforts to fight deflation. I recommend that Japan change its strategy. I recommend that Japan fight deflation with deflation just as firefighters often use smaller fires to burn a fire break in the path of out-of-control forest fires.
