Summary:
Most of the literature on retail fuel markets find high-frequency and asymmetric price cycles. This is typically explained by the model of Edgeworth price cycles. A key element of this model is that prices fall to marginal costs during a cycle. It seems challenging to address this assumption empirically. However, I use a natural experiment in the German fuel market to analyze the effects of an external cost shock. I find strong evidence that prices do not fall to marginal costs. This is not in line with Edgeworth cycles and thus, should be taken into account when analyzing fuel markets.
