Auctions and Market Design
This is the webpage for my course on Auctions and Market Design co-taught with Dirk Bergemann. It also includes four lectures from the course, Economic Engineering, which I co-teach with Axel Ockenfels and Alex Westkamp. Students are encouraged to take both courses for a broad introduction to Market Design.
Auctions and Market Design and the first part of Economic Engineering will use the flipped-classroom model. Before class you will view two lectures for the day—roughly 4.8 hours of material. The lectures are available on YouTube from the links below. You can do this whenever you want and at any playback speed. As you watch or after, you should write down three questions to bring to class. The best questions target broad ideas and research directions rather than some narrow element. For example, the question “I don’t understand how you got from line 3 to line 4 when you changed the order of integration” is better answered with a Google search “wiki order of integration“. A good question may help you understand market design research.
The purpose of the discussion sessions is to apply the lectures to real-world problems. Together we can get a glimpse of the market design process in many exciting settings.
The discussion sessions will not be recorded. Your real-time (1:30-4 pm) virtual attendance is expected. We will keep our cameras on except for emergencies and breaks. To facilitate discussion, we may call on you to ask one of your questions. We hope this format will be more active and engaging than the lectures alone. You will have to work a bit harder, but we expect that you will learn more.
Description [Requisites, Exercises, Grading]
Market design combines auction and matching theory with behavioral and experimental economics to design innovative markets to better meet goals. Applications are seen in almost all markets and government programs that assign and sometimes price scarce resources. Market design research leads to a better understanding of the incentives that guide behavior. Applications include matching students to schools, interns to hospitals, and kidneys to patients. In settings where prices are used to motivate behavior, auction markets are developed to assign and price scarce resources. Applications include markets in mobile communications, electricity, financial securities, transportation, and emissions.
Market design takes as given that participants interact in the market to maximize their objectives given the market rules. The question we ask is, “Are the market rules best-suited to the market’s objectives, or can they be improved?” This is an important and practical question. In nearly all cases, market rules can be improved, and often the improvements can transform entire industries for the better.
Congratulations to Paul Milgrom and Robert Wilson, two auction theorists and market designers, who received the 2020 Nobel Prize in economics “for improvements to auction theory and inventions of new auction formats.” [Scientific background] This course has benefited tremendously from the contributions of Robert Wilson and Paul Milgrom to auctions and market design.

Lecture 1: Introduction to auctions and market design, Peter Cramton [2h23m] View before Monday, 27 Sep 2021
Our first lecture presents an introduction to auctions and market design. Chen, Cramton, Ockenfels, and List (2020) presents a survey of recent work. For discussion of market design, see Roth (2002, 2015, 2018). For the initial paper on matching, see Gale and Shapley (1962). For matching with contracts, see Hatfield and Milgrom (2005), which nicely connects main results in auctions and matching. Bichler (2017) presents a nice introduction to market design from a linear programming perspective. Good textbooks on game theory are Fudenberg and Tirole (1991), Gibbons (1992), and Osborne and Rubinstein (1994). More recent work on algorithmic game theory is in Nisan, Roughgarden, Tardos, and Vazirani (2008). Parkes and Seuken (2021) is the first textbook on economics and computation. For textbooks on optimization, see Nocedal and Wright (2006) and Kochenderfer and Wheeler (2019).
Lecture 2: Auctions and bargaining, Peter Cramton [2h11m] View before Monday, 27 Sep 2021
McAfee (2017) covers the standard auctions in a fun 14-minute video. McAfee and McMillan (1987) is the seminal survey on auctioning a single item. Krishna (2009) provides an excellent treatment of auction theory. Vickrey (1961) is a pathbreaking paper on auctions, focusing on private values. Wilson (1967, 1969) introduces common value auctions. Milgrom and Weber (1982) generalize auction theory to affiliated values. Akbarpour and Li (2020) provide a nice rationale for some of the standard auctions. Cramton (1998) provides reasons ascending auctions perform well. Bergemann, Breuer, Cramton, and Ockenfels (2021) explore how a soft reserve price can capture the benefits of both ascending and sealed-bid auctions.
Lecture 3: Mechanism design, Peter Cramton [2h21m] View before Tuesday, 28 Sep 2021
The seminal paper is Myerson (1981). Borgers (2015) provides an excellent treatment of mechanism design. Vohra (2011) presents mechanism design from a linear programming perspective. Hartline and Lucier (2015) and Camara, Hartline, and Johnsen (2020) focus on algorithmic approaches that work well in a variety of environments.
Lecture 4: Auctioning many similar items, Peter Cramton [2h19m] View before Tuesday, 28 Sep 2021
Much of the material is in Ausubel, Cramton, Pycia, Rostek, and Weretka (2014). Ausubel and Cramton (2004) present the Vickrey auction with reserve pricing. Ausubel and Cramton (2001) discuss revenue-maximizing auctions with resale.
Lecture 5: Spectrum auctions and communications, Peter Cramton [2h21m] View before Wednesday, 29 Sep 2021
Coase (1959) is the first paper arguing for spectrum auctions. His testimony before Congress is wonderful; Cramton (2012) provides another example of Congressional testimony but on Medicare auctions. For an excellent discussion of spectrum auctions, see Milgrom (2004). Cramton, Shoham, and Steinberg (2006) cover combinatorial auctions. Cramton (2013) and Day and Cramton (2012) covers much of the material here. On bid signaling, see Cramton and Schwartz (2000). Cramton and Ockenfels (2017) provide a more recent treatment focusing on the German auctions. Open access wireless markets are presented in Cramton and Doyle (2017). Harchol et al. (2020) presents a similar idea for the internet backbone.
Lecture 6: Electricity market design and climate policy, Peter Cramton [2h21m] View before Wednesday, 29 Sep 2021
Electricity market design is discussed in Cramton (2017). The electricity transition is studied in Cramton, Bobbio, Malec, and Sujarittanonta (2020). Learning from market failures is essential in market design; Cramton (2021) (32-minute talk) discusses lessons from the 2021 electricity crisis. Climate policy is discussed in Cramton, MacKay, Ockenfels, and Stoft (2017) and MacKay, Cramton, Ockenfels, and Stoft (2015). Foundational research on engineering trust is presented in Bolton, Greiner, and Ockenfels (2013).
Lecture 7: Transportation and finance, Peter Cramton [2h29m] View before Wednesday, 29 Sep 2021
Transportation is discussed in Cramton, Geddes, and Ockenfels (2017). The arms race for speed is studied in Budish, Cramton, and Shim (2015). Flow trading is explored in Budish, Cramton, Kyle, Lee, and Malec (2021). Rostek and Yoon (2020) provide an excellent survey of financial market models. An interesting application of matching with prices in an artificial currency is Budish, Cachon, Kessler, and Othman (2017). Cramton, Ockenfels, Roth, and Wilson (2020) provide another example using both real and artificial currency to motivate supply and efficient allocation of scarce medical resources. Duffie (2020) argues for central clearing in the Treasury market—the paper is presented at CAFIN with questions from Cramton and others.
Lecture 8: Position auctions and common value auctions, Dirk Bergemann [2h19m] View before Thursday, 30 Sep 2021
Edelman, Ostrovsky, and Schwarz (2007) provide the basic results on position auctions. Varian (2007) covers similar ground with a different solution concept. Mas-Collel, Whinston, and Green (1995), chapter 23, remains one of the best treatments of mechanism design and incentives. Nisan, Tardos, and Vazirani (2008), chapter 28, gives an insightful introduction with a more algorithmic perspective on the generalized second-price auction.
Bergemann, Brooks, and Morris (2020) provides the basic results on common value auctions. Bergemann, Brooks, and Morris (2019) give a novel perspective on the revenue equivalence theorem. Bulow and Klemperer (2002) is a splendid and transparent introduction into the new insights that arise in common value auctions. Bulow and Klempeer (1996) is an excellent treatment of optimal auctions with interdependent values and more.
Lecture 9: Price discrimination and Bayesian persuasion, Dirk Bergemann [2h17m] View before Friday, 1 Oct 2021
Kamenica and Gentzkow (2011) provide the basic results on Bayesian persuasion and information design. Bergemann and Morris (2019) provide a survey of this growing area of research and generalizations to strategic settings.
Lecture 10: Dynamic mechanism design: efficiency and revenue, Dirk Bergemann [2h12m] View before Friday, 1 Oct 2021
Bergemann and Valimaki (2010) provide basic results on dynamic mechanism design from an efficiency perspective. Bergemann and Valimaki (2019) provide a survey of the efficiency results over the last decade.
Courty and Li (2000) provide basic results on dynamic mechanism design from a revenue perspective. Borgers (2015) is an excellent reference on mechanism design. Chapter 11 covers much of the material presented here.
