Diesel Price Adjustments: Further Evidence for Spain

A fertile literature analyses the asymmetric cost pass‐through between retail fuel prices and oil prices (“rockets and feathers”) for different countries and time periods. Recent legislative changes in Spain, provoking a true market shock, and the inconclusive results from previous studies, make it worth revisiting the rockets and feathers effect in the Spanish retail market. Using two series of 365 weekly and 1825 daily prices of diesel collected between January 2011 and December 2017, our results show that the null of existence of asymmetries is either rejected or not depending on the period under consideration and the
frequency of the data
