Title: Revenue Maximization with Non-Obligatory and Deferred Inspection

Abstract: We consider the problem of selling $k$ items to $n$ unit-demand buyers to maximize revenue in two settings with inspection. In the first setting, the buyers' values are independently distributed (not necessarily identical) but unknown to the buyers themselves, with the option of allowing buyers to inspect the item at a cost. In the second setting, the buyers' values are known to themselves, and the auctioneer can inspect to learn buyers' values and potentially punish the non-truthful buyers.

For both problems, we present an approximation mechanism that achieves $1-1/\sqrt{k+3}$ of the optimal revenue in expectation. Our mechanisms are sequential and have a simple implementation that works in an online setting where the buyers arrive in an arbitrary unknown order and yet achieve the aforementioned approximation with respect to the optimal offline mechanism.

Based on the following two papers: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3855810 and https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3700525
