Abstract

This study empirically analyzes that the asymmetry of domestic gasoline price adjustment to the crude oil price changes can vary depending on the level of gasoline price using quantile autoregressive distributed lag model. The data used are the weekly average Dubai price, domestic gasoline price at refiners and gas stations from the first week of May 2008 to the second week of October 2022. The study estimates three price transmission channels: changes in gas station gasoline prices in response to changes in Dubai oil prices, changes in refiners gasoline prices in response to changes in Dubai oil prices, and changes in gas station prices relative to refiners gasoline prices. As a result, the price adjustment of refiner's gasoline price with respect to Dubai oil price appears asymmetrically across all quantiles of gasoline price, whereas the adjustment of gas station prices for Dubai oil price and refiner's gasoline price tend to be more asymmetric as the quantile of gasoline price increases. Such a result is presumed to be due to changes in the inventory cost of gas stations. When the burden of inventory cost is high, gas stations have an incentive to more actively pass the increased buying price on their selling price.

동 연구는 휘발유 가격 수준에 따른 국제 유가에 대한 국내 가격 조정의 비대칭성을 분위수 자기회귀시차분포 모형을 사용하여 확인한다. 추정에 사용된 자료는 2008년 5월 첫 번째 주부터 2022년 10월 두 번째 주까지의 주간 평균 두바이유가, 정유사 휘발유가, 주유소 휘발유가이다. 추정은 두바이유가에 대한 주유소 휘발유 가격, 두바이유가에 대한 정유사 휘발유 가격, 정유사 휘발유 가격에 대한 주유소 가격의 변화, 세 가지에 대해 이루어졌다. 추정 결과, 두바이유가에 대한 정유사 휘발유 가격의 조정은 휘발유 가격의 모든 분위에 걸쳐 비대칭적으로 나타난 반면 두바이유가와 정유사 휘발유 가격에 대한 주유소 가격의 조정은 휘발유 가격의 분위수가 높을수록 비대칭적으로 나타났다. 이와 같은 결과는 휘발유 가격 변화에 따른 주유소의 재고 비용 변화에 기인하는 것으로 추측된다. 재고 비용에 대한 부담이 높을수록 주유소에게는 상승한 휘발유의 매입가격을 보다 적극적으로 판매가격에 전가하고자 하는 유인이 있다.
