Optimal starting price for eBay-like online auctions. (English) Zbl 1272.91059

Summary: Reserve price auctions are one of hot research issues in traditional auction theory. Here we study the starting price in an online auction, the counterpart of the public reserve price in a traditional auction. By considering three features of eBay-like online auctions: stochastic entry of bidders (subject to Poisson process), insertion fee proportional to the starting price, and time discount, we have analyzed the properties of extremum points of the starting price for maximizing the seller’s expected revenue, and found that, under certain conditions, the optimal starting price should be at the lowest allowable level, which is contrary to the results from the classic auction theory and finds its optimality in reality. We have also developed a general extended model of multistage auctions and carried out analysis on its properties. At last, some directions for further research are also put forward.
