Auction Invention Put to Use
Over the years, I’ve invented several new multi-item auction mechanisms intended for use in practice. Portugal has now adopted the Day-Milgrom core-selecting auction mechanism for an upcoming radio spectrum auction. Detailed rules can be found here or on the Portuguese regulator’s website.
A paper explaining the logic of this design — “Core-Selecting Auctions” — can be found in the Publications section of this website (link).
