任何垂直移动的迹象（表明在NAIRU水平的失业率上通胀出现上升 ） ， 而不是水平移动迹象（失业率下降而不出现CPI通胀 ） ， 对于日本银行来说都是好事，对总体经济亦然。
Any sign of a vertical move (implying higher inflation with an unemployment rate at NAIRU), rather than a horizontal one (a lower unemployment rate without CPI inflation), will be welcomed by the BOJ, and good for the economy at large.
