Secret reserve prices in auctions impact seller revenue and bidders' utility.
The article explores how different types of auction strategies affect revenue and buyer satisfaction. It shows that setting a public reserve price slightly higher than the seller's value can maximize revenue. Adding an entry fee along with this reserve price can increase revenue even more. In some auction formats, using a secret reserve price can lead to fewer buyers, lower chances of a sale, and less profit for the seller. However, in a different auction format, a secret reserve price equal to the seller's value can actually benefit buyers and increase seller revenue.
