Does this imply that inequalities are irrelevant for central bankers? Not at all, as first, monetary policy may have impact on inequalities, and second, stability is conducive to equity”.Benoît Cœuré, ECB, Oct 17, 2012AbstractInequality has been largely ignored in the literatureand practice ofmonetary policy, butis gaining more attentionrecently. We look at how a decade of unconventional monetary policy (UMP) in Japan affected inequality among households using survey data. Our vector autoregression (VAR) results showthat UMP widened income inequality,especially after 2008 whenquantitative easing became more aggressive. This is largely due to the portfolio channel. To the best of our knowledge, this is the first study to empirically analyze the distributional impact of UMP. Japan’s extensiveexperience with UMP may hold important policy implicationsfor other countries.
