New Facts about Firms' Inflation Expectations: Simple Tests for a Sticky Information Model

In this paper, we use a large dataset based on firm-level micro-data from the Tankan survey to examine firms' inflation expectations. We first present two basic findings: (i) firms' inflation expectations are downwardly rigid at zero, and (ii) differences in firms' inflation expectations are larger across firm sizes than across sectors. We then report three findings which are in line with predictions of the simple sticky information model proposed by Mankiw and Reis (2002). First, in each period, a number of firms do not revise their expectations. Second, the frequency of forecast revisions is constant over time. Third, our estimates of the frequency of forecast revisions based on the Tankan survey are much smaller than those in previous studies and are much closer to the value that Mankiw and Reis (2002) assumed in their simulation exercises.
