TOKYO: Bank of Japan board member Takehiro Sato said labour market reform and other measures to boost Japan’s growth potential must accompany monetary easing to raise the country’s low long-term inflation expectations. Prolonged economic stagnation has pushed down long-term inflation expectations to around zero percent, and it is not easy to raise them even through massive monetary stimulus if monetary policy is the “only game in town,” Sato said in a speech at Yale University on Tuesday. “Given that monetary policy on its own has limited effects, it is vital to make steady efforts, such as through labour market reform … to change Japan’s conservative inflation expectations,” Sato said in the text of his speech posted on the BOJ’s website on Wednesday. Japanese companies and labour unions have traditionally prioritised job security over pay rises, a practice that has restrained wage increases and worked to push down long-term inflation expectations, Sato said.
