Another concern for the cautionary wing of the BOJ centers on the unusual structure of Japan’s economy. Japan’s jobless rate – at 4 percent – is half that of the United States. But wages remain on the decline, down 1.1 percent in November from a year earlier to mark the third straight month of falls.

Unable to fire workers in mass layoffs because of rigid labour rules, Japanese firms are unwilling to raise salaries. Without a rise in wages, the only practical way overall prices could go up would be through higher commodity and fuel costs which would curb consumption, not boost it, the BOJ has argued.
