Tax holidays and the heterogeneous pass-through of gasoline taxes
利用2022年2月至6月美国东海岸108个城市的日度数据，估计汽油税平均传导率为79%，并发现不同地区的传导率存在差异，受供应约束、市场隔离和溢出效应影响。
The pass-through of gasoline taxes to retail prices plays a vital role in determining the extent to which a fuel tax suspension policy provides financial relief to consumers. Given the increased interest in utilizing such “tax holidays” to mitigate the unprecedented rise of gasoline prices in 2022, it is important to obtain location-specific pass-through estimates that will inform future similar policy efforts. Using daily city-level data from a sample of 108 cities in 15 East Coast states and the District of Columbia during the period February 1, 2022-June 30, 2022, I estimate an average pass-through rate of gasoline taxes of 79%. My subsequent analysis reveals heterogeneity in pass-through across locations and explores supply constraints, market isolation, and spillover effects as possible contributing factors to this heterogeneity.
