Abstract: 

Algorithms and the Internet are revolutionizing how society allocates its resources. Examples range from wireless spectrum and electricity to online advertising and carpooling opportunities. A fundamental question is how to allocate such resources efficiently by designing robust computational markets.

In this talk I will demonstrate recent progress on this question by considering a problem crucial for major industry players like Google: how to design revenue-maximizing allocation mechanisms. Most existing designs hinge on “getting the price right” – selling goods to buyers at prices low enough to encourage a sale, but high enough to garner non-trivial revenue. This approach is difficult to implement when the seller has little or no a priori information about buyers’ valuations, or when the setting is sufficiently complex, as in the case of markets with heterogeneous goods.

I will show a robust approach to designing auctions for revenue, which “lets the market do the work” by allowing prices to emerge from enhanced competition for scarce goods. This work provides guidelines for a seller in choosing among data acquisition and sophisticated pricing, and investment in drawing additional buyers.
