How quickly do firms raise price expectations after inflation data?
Core argument: A 1 percentage point increase in CPI inflation is associated with a 0.6 percentage point rise in firms' year-ahead own-price expectations one day after the CPI release, with the coefficient remaining near 0.6 on the second day, significant at the 5% level.
After documenting that firms are attentive to CPI inflation changes, we analyse whether these changes have meaningful effects on their own-price expectations. We begin by estimating the event study specification [using daily data] with own-price expectations as the dependent variable. The results are presented in Figure 7. We find no significant effect of CPI inflation changes on own-price expectations prior to the release. However, following the release, the coefficients become positive and statistically significant. At t + 1, the result suggests that a 1 ppt increase in CPI inflation is associated with a 0.6 percentage point increase in year-ahead own-price expectations. On the second day after the release, the coefficient remains around 0.6, and is significant at the 5% level. The significant effects on t + 1 coincide with the day when firms receive a reminder email, which leads to more responses and hence more precisely estimated coefficients.
