消费者拍卖在互联网商务的早期非常流行，但今天的在线卖家大多使用张贴的价格。来自eBay的数据显示，正在出售的商品或提供这些商品的卖家的成分变化无法解释这种演变。相反，使用拍卖的卖家的回报已经减少。我们开发了一个模型来区分两个假设：买方需求的转移远离拍卖，和一般缩小有利于张贴价格的卖方利润率。我们的估计表明，前者更为重要。我们还提供了拍卖仍然使用的证据，以及为什么一些卖家可能会继续使用拍卖和公布的价格。
Consumer auctions were very popular in the early days of internet commerce, but today online sellers mostly use posted prices. Data from eBay shows that compositional shifts in the items being sold, or the sellers offering these items, cannot account for this evolution. Instead, the returns to sellers using auctions have diminished. We develop a model to distinguish two hypotheses: a shift in buyer demand away from auctions, and general narrowing of seller margins that favors posted prices. Our estimates suggest that the former is more important. We also provide evidence on where auctions still are used, and on why some sellers may continue to use both auctions and posted prices.
