摘要
在本文中，我们估计了网上拍卖的低效率。由于网络欺诈，网上拍卖效率低下。网络欺诈的一个典型例子是，卖家即使收到了付款，也不向中标者发送货物。因此，投标人始终承担欺诈风险，这种风险可能导致交易失败。在我们的实证例子中，我们使用2009年举行的eBay PlayStation 3拍卖。我们发现，超过5%的在线拍卖的效率损失超过30美元。此外，我们还发现，无效的在线拍卖的概率大于0.25。
In this paper, we estimate the inefficiency in online auctions. Online auctions can be inefficient due to the Internet fraud. A typical example of Internet fraud is when sellers do not send goods to winning bidders even though they have received payment. Therefore, bidders always bear a risk of fraud, and this risk may lead to transaction failure. In our empirical example, we use eBay PlayStation 3 auctions held in 2009. We find that the efficiency loss is over $30 for more than 5% of online auctions. Furthermore, we also find the probability of the inefficient online auction is more than 0.25.
