Abstract

Japan has failed to escape from deflation despite extraordinary monetary policy easing over the past four years. Monetary easing undoubtedly stimulated aggregate demand, leading to an improvement in the output gap. However, since the Phillips curve was almost flat, prices hardly reacted. Against this background, the key question is why prices were so sticky. To examine this, we employ sectoral price data for Japan and seven other countries including the United States, and use these to compare the shape of the price change distribution. Our main finding is that Japan differs significantly from the other countries in that the mode of the distribution is very close to zero for Japan, while it is near 2 percent for other countries. This suggests that whereas in the United States and other countries the "default" is for firms to raise prices by about 2 percent each year, in Japan the default is that, as a result of prolonged deflation, firms keep prices unchanged.
