**Summary:**The course covers classic and state-of-the-art results on computational and
game-theoretic questions related to electronic marketplaces.

**Abstract: **This PhD-level course covers classic and state-of-the-art results on computational and game-theoretic questions related to electronic marketplaces. We will start with classic and recent results in mechanism design. We will then cover integer programming algorithms for scalable market clearing. Further topics include expressiveness in mechanisms, preference elicitation from multiple parties, multi-stage mechanisms, communication complexity, automated mechanism design, mechanism design for computationally limited agents, online (i.e., dynamic) mechanisms, and revenue maximization techniques. Applications discussed vary from year to year, and may include combinatorial auctions, sponsored search, display advertising markets, kidney exchange, prediction markets, and automated market making.

**Instructor:** Prof.
Tuomas Sandholm (sandholm@cs.cmu.edu)

**This page:** http://www.cs.cmu.edu/~sandholm/cs15-892F13/cs15-892.htm

**Class times:** MoWe 10:30-11:50 am in GHC 4101. First lecture is on September 9th.

**Instructor’s office hour:** By appointment.

**Reading materials:**

There is no book that adequately covers all of the covered
topics. However, we will be using the book **Combinatorial Auctions** (MIT Press 2006). In addition, we will use a
collection of readings from recent research papers, chapters that are about to
appear in other books, and slides by the instructor. Some of these papers are brand new, and have
not even appeared publicly yet.

**Format: **

- Lectures by Prof. Sandholm. In addition, guest lectures by outside experts.
**In advance of each lecture, each student is expected to download the paper and the slides for that lecture from the course web page, and to read the paper carefully before the lecture.**There may be surprise quizzes on the readings.- Three homework assignments, which will mostly consist of analytical questions.
- Final project. Each student is expected to complete an original final project
(alone, or for a larger project, in a pair). The students are free to
pick the topics of the final projects, but they have to be related to the
topic of the course. The projects can involve analytical work, computer experiments, building a prototype,
etc. The project might also involve applying some of the techniques learned in this course to the student’s
research in another area. Two-page project plans are due on October 2nd by the beginning of
class. Students are expected to present their final projects in the last couple of lectures.
The writeups of the final projects are due on December 4
^{th}(i.e., last class) in the beginning of class.These are hard deadlines.

**Evaluation:** Participation 10%, homework assignments
and quizzes 40%, final project 50%. The course must be taken for credit: there is no audit option.

**Prerequisites:** No background is required in game theory, mechanism design, or integer programming. Basic knowledge of probability theory, algorithms, and computational complexity is needed. This is a full-semester course given by the Computer Science Department primarily to
Ph.D. candidates. However, others may also take it with the instructor's permission.

**Title:**Draft Auctions.**Abstract:**We introduce draft auctions, which is a sequential auction format where at each iteration players bid for the right to buy items at a fixed price. We show that draft auctions offer an exponential improvement in social welfare at equilibrium over sequential item auctions where predetermined items are auctioned at each time step. Specifically, we show that for any subadditive valuation the social welfare at equilibrium is an O(log^2(m)) approximation to the optimal social welfare, where m is the number of items. We also provide tighter approximation results for several subclasses. Our welfare guarantees hold for Bayes-Nash equilibria and for no-regret learning outcomes, via the smooth-mechanism framework. Of independent interest, our techniques show that in a combinatorial auction setting, efficiency guarantees of a mechanism via smoothness for a very restricted class of cardinality valuations, extend with a small degradation, to subadditive valuations, the largest complement-free class of valuations. Variants of draft auctions have been used in practice and have been experimentally shown to outperform other auctions. Our results provide a theoretical justification. Joint work with Nikhil Devanur and Vasilis Syrgkanis.

- Nov 21: Optional bonus talk on automated mechanism design by Costis Daskalakis (3:30-4:30 pm in Wean Hall 8220).
**Title:**An Optimization Approach to Mechanism Design.**Abstract:**I will present an optimization framework based on optimal transport theory characterizing the structure of revenue-optimal mechanisms in single-bidder multi-item settings. Our framework provides closed-form descriptions of mechanisms, generalizes Myerson's celebrated single-item auction, and exhibits simple settings with very rich structure in the optimal mechanism. This part of the talk is based on work with Alan Deckelbaum and Christos Tzamos. For the second part of the talk, which will be algorithmic, I will revisit the question posed by Nisan and Ronen in the birth of algorithmic mechanism design: How much harder is optimizing an objective over inputs that are furnished by rational agents compared to when the inputs are known? I will present a computationally efficient reduction from mechanism design (i.e. optimizing an arbitrary objective over rational inputs) to algorithm design (i.e. optimizing the same objective over known inputs) in general Bayesian settings. This part of the talk is based on work with Yang Cai and Matt Weinberg. - Nov 25: Homework 3 due by the beginning of class. Sponsored search: basics and newest results on ranking and pricing. Slides.
