Research into the determinants of online auction prices has tended to group them into buyer factors, seller factors and site factors. A case is presented which recounts how a $30 handbag was sold for $ 22,750 in an online auction shortly after a national sport event. Analysis of the case indicates that, in addition to the three groups of factors already identified, other factors can exert a considerable influence on the final auction price. A model is proposed which depicts five groups of factors impacting the final price: buyer factors, seller factors, site factors which are expanded to include timing of the auction, and site brand strength; product factors which include product features, brand strength, and brand extension/association; and promotion, which includes media publicity. While not all factors will impact on every auction, due consideration should be accorded each of them by both buyers and sellers.

The online auction has become an important channel for procurement and sourcing management. As firms often expect lower procurement prices through online auctions, how the prices are determined in online auctions should be of major interest to procurement managers and supply chain researchers. Despite the abundant empirical studies on online auction prices, an aggregated view is still absent. This study fills this gap with a review of extant studies. More specifically, this study provides summaries of all major theories behind online auction pricing, defines and analyzes often encountered econometric issues, and discusses how the treatments of these issues have been operationalized. Towards the end, existing findings on determinants of online auction prices are integrated and examined. The purpose of this study is to provide a convenient and precise package of current studies for researchers and professionals.

Analysis of the case indicates additional factors which can exert a considerable influence on the final auction price. A model is proposed which depicts five groups of factors impacting the final price: buyer factors, seller factors, site factors which are expanded to include timing of the “action”, and site brand strength; product factors which include product features, brand strength, and brand extension/association; and promotion, which includes media publicity. While not all factors will impact on every auction, due consideration should be accorded each of them.

We employ a novel approach to identify overbidding in auctions. We compare online auction prices to fixed prices for the same item on the same webpage. In detailed data on auctions of a board game, 42 percent of auctions exceed the simultaneous fixed price. The result replicates in a broad cross-section of auctions (48 percent overbidding). A small fraction of overbidders, 17 percent of bidders, suf fices to generate the large fraction of auctions with overbidding. We show that the observed behavior is inconsistent with rational behavior, even allowing for uncertainty about prices and switching costs, since the expected auction price also exceeds the fixed price. Limited attention best explains our results. (JEL D12, D44)
