Susan Carleton Athey (born November 29, 1970) is an American economist. She is The Economics of Technology Professor at the Stanford Graduate School of Business. Prior to joining Stanford, she was a professor at Harvard University. She is the first female winner of the John Bates Clark Medal. She currently serves as a long-term consultant to Microsoft as well as a consulting researcher to Microsoft Research.
Athey attended Duke University from the age of 16. As an undergraduate at Duke, she completed three majors, in economics, mathematics, and computer science. She got her start in economics research during a summer job preparing bids for a company that was selling personal computers to the government through procurement auctions, working on problems related to auctions with Professor Bob Marshall. Bob Marshall, a professor at Duke University who worked on defense procurement and helped her ith procurement auctions. She was involved in a number of activities at Duke and served as treasurer of Chi Omega sorority and as president of the field hockey club.
Athey is married to economist Guido Imbens. They have three children.
Athey's first position was as an Assistant, Associate Professor and Castle Krob Career Development Chair at the Massachusetts Institute of Technology for six years before returning to Stanford's Department of Economics as Professor holding the Holbrook Working Chair for another five years. She then served as Professor of Economics at Harvard University until 2012, when she returned to Stanford Graduate School of Business, her alma mater.
Applied Auction Research
Since auctions were the reason Susan went into economics. She has contributed on all dimensions to research on auctions. Susan's theoretical work on collusion in repeated games applies to auctions. As well as her existence theorem for sets with private information, and she has done an innovative job on the econometrics of auctions. She has performed significant empirical work in econometrics of auctions. She also designed work that has had significant effects on business and public policy. Susan and Jonathan Levin examined the U.S. Forest Service's, oral ascending auctions for the rights to cut timber in the national forests. Typically, a given tract contains several different species of timber-yielding trees. The Forest Service publishes an estimate of the proportions of the various species based on an inspection. Potential bidders then can conduct their inspections. Bids are multidimensional: amounts to be paid per unit for each species. The winner is determined by aggregating each bidder's offer using the Forest Service's estimated proportions. The actual amount the winner pays, however, is computed by applying the bid vector to the exact amounts that are ultimately harvested (the winner has two years to complete the harvest). These rules create an incentive for a bidder whose estimate of the proportions differs from that of the Forest Service to skew its bidding, raising the price bid for the species that the bidder believes are less common than does the Forest Service. Conversely lowering the price bid for the species that the bidder believes are more common than does the Forest Service. For example, suppose there are two species and the Forest Service estimates that they are in equal proportions, but a bidder believes they are in dimensions 3:2. Then bids of ($100, $100) and ($50, $150) yield the same amount under the Forest Service proportions and so are equally likely to win, but the bidder expected payments under the first and under the second is $90 (Roberts, John).
Athey's early contributions included a new way to model uncertainty (the subject of her doctoral dissertation) and understand investor behavior given uncertainty, along with insights into the behavior of auctions. Athey's research on decision-making under uncertainty focused on conditions under which optimal decision policies would be monotone in a given parameter. She applied her results to establish conditions under which Nash equilibria would exist in auctions and other Bayesian games.
Athey's work changed the way auctions are held. In the early 1990s Athey uncovered the weaknesses of an overly lenient dispute mechanism through experiences selling computers to the U.S. government at auctions, discovering that open auctions which resulted in frequent legal disputes followed by settlements were actually rife with collusion, e.g., auction winners shared a portion of their spoils with losers who had cooperated in bidding. She also aided British Columbia in the design of the pricing system used for publicly owned timber. She also published articles about auctions for online advertising and advised Microsoft about the design of their search advertising auctions.
Athey has served as an associate editor of several leading journals, including the American Economic Review, Review of Economic Studies, and the RAND Journal of Economics, as well as the National Science Foundation economics panel, and she also served as an associate editor for Econometrica, Theoretical Economics, and the Quarterly Journal of Economics. She is a past co-editor of the Journal of Economics and Management Strategy and American Economic Journal: Microeconomics. She was the chair of the program committee for the 2006 North American Winter Meetings, and has served on numerous committees for the Econometric Society, the American Economic Association, and the Committee for the Status of Women in the Economics Profession. She is a member of President Obama's Committee for the National Medal of Science.
