This paper explores how a seller should transmit product information to bidders with horizontally differentiated preferences. Under cheap-talk, we show that, in an informative equilibrium, the seller provides less precise information for more popular product attributes. Second, for any given...

We present an approach to automate the bidding and budgeting of multi-unit digital advertising campaigns. Such campaigns typically involve groups of ad-units that span multiple user segments, ad-delivery channels and media that together are meant to deliver on the advertiser's goals. Our model...

An organization must decide which proposals to fund. In evaluating the proposals, the organization may rely on those applying for funding to produce evidence about the merits of their own proposals. We consider the role of a capacity constraint preventing the organization from funding all...

We study optimal auctions in a symmetric private values setting, where bidders' care about winning the object and a receiver's inference about their type. We reestablish revenue equivalence when bidders' signaling concerns are linear, and the auction makes participation observable via an entry...

We study optimal auctions in a symmetric private values setting, where bidders have signaling concerns: they care about winning the object and a receivers inference about their type. Signaling concerns arise in various economic situations such as takeover bidding, charity auctions, procurement...

Dealers, who strategically supply liquidity to traders, are subject to both liquidity and adverse selection costs. While liquidity costs can be mitigated through inter-dealer trading, individual dealers' private motives to acquire information compromise inter-dealer market liquidity. Post-trade...

This paper provides a more general sufficient condition than Hummel and McAfee (2015) for optimal information disclosure in auctions when there are three bidders. We show that the optimal disclosure policy is related to the skewness of the distribution of bidders' valuations. Specifically, if...

Poor user experiences with search advertisements can lead to ad avoidance thus reduce search engine’s long-term revenue. We capture the effect of negative user experiences on search engine’s future revenue in a new variable called “shadow costs” and examine the optimal keyword auction...

Keyword auctions are another multi-billion dollar application of auctions after the celebrated eBay-like business-to-consumer auctions in electronic commerce. Inevitably, keyword auctions have recently gained attention among researchers. Questions regarding what (is keyword auction), why (we...
