【 摘 要 】

This report documents two mathematical models for extracting the price-demand relationship, commonly known as the demand function or demand curve, for consumer products using on-line auction bid data. The first model assumes that all bidding sequences are equally likely; the second model assumes that the bidders arrive in Poisson streams and utilizes the time of bid information. Our goal is to estimate, from recorded bids in n auctions, the proportions of potential (in addition to the known) bidders who are willing to bid a price. 36 Pages
