Storable products allow consumers to time their purchases to exploit price fluctuations. It has been documented that during promotions consumers buy more. The additional purchases are potentially intended not only for current use, but to be stockpiled for future consumption. This paper discusses the predictions of a consumer inventory model and reviews the available evidence. We then discuss the implications for demand estimation and present estimates of the economic magnitude of the dynamic effect of storability.
