Consumer stockpiling behavior in the retail gasoline market

ABSTRACT

I examine consumer stockpiling behavior in the retail gasoline market and factors that affect consumer stockpiling. Past research such as Hendel and Nevo (2006b Hendel, I. , and A.Nevo . 2006b. “Sales and Consumer Inventory.” The Rand Journal of Economics 37 (3): 543–561. doi:10.1111/(ISSN)1756-2171.[Crossref], [Web of Science ®] , [Google Scholar]) found evidence that implies stockpiling behavior. However, they did not observe actual inventory or consumption and have to rely on simplifying assumptions about these quantities. I collected a novel data set of gasoline purchase history of consumers with actual inventory and consumption to test several hypotheses that relate consumer stockpiling to price, duration between purchases, and consumption. I found that consumers purchase more gasoline when their inventory is low and those holding high inventory are more price sensitive. Consumption habits after a purchase may change due to two forces: previous consumption habit and purchase price. The exact change in consumption and duration between purchases depends on which force is stronger.
