Abstract
In this paper, we revisit the empirical observation that prices rise like rockets when input costs increase but fall like feathers when input costs decrease. The analysis draws on a novel data set that includes daily retail prices of gasoline from 12,804 stations in Germany from January 1, 2014 to December 31, 2018. Our findings based on pooled-panel asymmetric error correction models indicate that the pattern of rockets and feathers is the norm rather than the exception. Our results further show that temporal aggregation of station-level price data leads to inaccurate inferences and could account for the inconclusive findings in the literature.
