Was the German fuel discount passed on to consumers?
利用法国作为对照组，采用双重差分法分析德国加油站是否将2022年6月至8月的汽油税减免传递给消费者，发现平均传递率很高但不完全，且农村和南部地区传递率较低。
In this article, I analyze whether German gasoline stations passed on the gasoline tax reduction to consumers. I use a difference-in-differences approach with France as the control group, as well as data for all countries in the European Union. The German fuel discount was in effect from June to August 2022. As I am the first to use complete French and German high-frequency data for the entire treatment period, I can examine how the pass-through of the tax cut evolved over time, varied for different brands, and in various geographic regions. I find a substantial variance in pass-through rates over time and space. On average, the pass-through of the fuel discount was very high but remained incomplete for all fuel types. The pass-through rates were systematically lower in rural regions and in the south of Germany. • Pass-through of the German gasoline tax reduction was high but incomplete. • There was no price increase before the gasoline tax reduction came into effect. • Pass-through rates vary substantially over time and in geographic regions. • There were no differences in pass-through between the major brands.
