Inflation rates in advanced economies experienced two consecutive puzzles during the period following the global financial crisis—unexpectedly high inflation from the end of 2009 to 2011 and unexpectedly low inflation from 2012 to the middle of 2014. We investigate these developments in two ways. First, we show that accounting for inflation expectations by households explains a significant share of the inflation puzzles at the international level. Second, we find that, for Canada, elevated competition in the retail sector is also important for understanding inflation dynamics in the post-crisis period.
