Topics in Market Design: Econ 287/365: Winter quarter, Itai Ashlagi

Itai Ashlagi will be teaching Econ 287 this quarter, on topics in market design.  It's highly recommended.

He writes that the syllabus below is very tentative, and will depend in part on how many of the enrolled students took Econ 285 (Ostrovsky and Roth) in the Fall (back in 2023:-)

Topics in Market Design 2024, Itai Ashlagi

Market design is a field that links the rules of the of the marketplace to understand frictions, externalities and more generally economic outcomes. The course will provide theoretical foundations on assignment and matching mechanisms as well as mechanism design. There will be emphasis on theories at the intersection of economics, CS and operations as well as applications that arise in labor markets, organ allocation, platforms.

The class will further expose students to timely market design challenges and will we will host a few guest lectures. The class offers an opportunity to begin a research project. Students will reading critique papers, present papers and write a final paper.

Lectures: Monday 10:30am-1:20pm Shriram 052

Course requirements: (i) reading and writing critiques about papers, (ii), presenting papers in class, and (iii) a term paper.

Two courses on matching and market design in Stanford's MS&E department, by Ashlagi and Saberi (first meeting is today)

Itai Ashlagi and  Amin Saberi are offering courses on matching theory and market design this quarter. First meetings are today, in the morning and in the afternoon:

MS&E 230: Market design for engineers

Itai Ashlagi  T-Thu 9:45-11:15

Course description:  Marketplaces use algorithms and sets of rules in order to allocate resources among self-interested agents, who often hold necessary information. This course will provide key principles in engineering a marketplace, to identify relation between the rules in the marketplace and market failures, and how to redesign them to achieve desirable outcomes.  The course provides foundations of resource allocation systems building on game theoretic analysis.  The course explores economic and algorithmic tools from matching, mechanism design, auction theory and information design. Cases of existing and future marketplaces will be discussed, including ride-sharing systems, school choice programs, online dating, online advertising and organ allocation.

Some applied questions include: How should we assign students to schools? How should we match doctors to residency programs? Shall we price roads and the impact of tolls? How should we allocate affordable housing and arrange waiting lists? How should we incentivize hospitals to collaborate on kidney exchanges? How should we allocate food to food banks? How should reduce organ discards?  How can we assist in migration?  Why is some marketplace decentralized (college admissions) and others are more controlled? How should platforms set incentives? What incentives and frictions arise in blockchains? 

 **********

MS&E 319: Matching Theory
Amin Saberi  
T Th 01:30p-03:00p

The theory of matching with its roots in the work of mathematical giants like Euler and Kirchhoff has played a central and catalytic role in combinatorial optimization for decades. More recently, the growth of online marketplaces for allocating advertisements, rides, or other goods and services has led to new interest and progress in this area.  


The course starts with classic results characterizing matchings in bipartite and general graphs and explores connections with algebraic graph theory and discrete probability. Those results are complemented with models and algorithms developed for modern applications in market design, online advertising, and ride-sharing.

Topics include: 


Matching, determinant, and Pfaffian

Matching and polynomial identity testing
Isolating lemma and matrix inversion, matching in RNC

Combinatorial and polyhedral characterizations 
The assignment problem and its dual, primal-dual, and auction algorithms
Tutte’s theorem, Edmond’s LP, and the Blossom algorithm

The Gallai-Edmonds decomposition, Berge-Tutte formula, and applications in Nash bargaining

The stable marriage problem
Gale-Shapley theorem, incentive and fairness issues
LP characterization, counting stable matchings

Matching in dynamic environments
Online matching under various arrival models
Applications in ride-sharing and online advertising

 

Computation of matching  

Combinatorial vs continuous algorithms, near-linear time algorithms

Matchings in sub-linear time, streaming computational models

Sparsifiers and stochastic matching 

Counting matchings  
The Van der Waerden conjecture, Bregman-Minc’s inequality
Deterministic approximations, counting matchings in planar graphs
Markov chain Monte Carlo algorithms, sequential importance sampling
The Ising model, applications, and basic properties

Market design course for health policy and medical students, at Stanford, taught by Alex Chan and Kurt Sweat

 Starting tomorrow, a short course in market design:

BIOS 203, Fall 2021: Market Design and Field Experiments for Health Policy and Medicine 

Primary Instructor: Alex Chan chanalex@stanford.edu | Office Hours: By appointment

Secondary Instructor: Kurt Sweat kurtsw@stanford.edu | Office Hours: By appointment


Description. Market design is an emerging field in economics, engineering and computer science about how to organize systems to allocate scarce resources. In this course, we study (1) the theory and practice of market design in healthcare and medicine, and (2) methods to evaluate the impact of such designs. Students will be provided with the necessary tools to diagnose the problems in markets and allocation mechanisms that render them inefficient, and subsequently develop a working toolbox to remedy failed markets and finetune new market and policy designs.

With a practical orientation in mind, we will learn how to construct rules for allocating resources or to structure successful marketplaces through successive examples in healthcare and medicine: medical residency matching, kidney exchange, allocation of scarce medical resources like COVID vaccine and tests, medical equipment procurement, online marketplace for doctors, and, if time permits, reward system for biopharmaceutical innovation. Guest lectures by practicing market designers and C-suite healthcare executives (CEO, CFO) would feature in the course as well.

An important goal of the class is to introduce you to the critical ingredients to a successful design: a solid understanding of institutions, grasps of economic theory, and well-designed experiments and implementation. In the final sessions, students will also learn how to design and deploy one of the most powerful tools in practical market design: A/B testing or randomized field experiments. These techniques are widely used by tech companies like UBER, Amazon, eBay, and others to improve their marketplaces.

At the end of the course, students should have acquired the necessary knowledge to become an avid consumer and user, and potentially a producer, of the market design and field experimental literature (recognized by 4 recent Nobel Prizes in Economics: 2007/2012/2019/2020).

Market design comes to Harvard Law School

Here's a piece from the Harvard Law Bulletin that caught my eye:
Holger Spamann brings new thinking to the structure of his class and casebook 

He's teaching "a corporate finance course divided into four different modules, any of which students can opt out of depending on their knowledge level.

"A student who comes in with a great deal of experience in the field will be able to skip the initial module on basic valuation. Subsequent modules cover diversification and market efficiency, capital structure, and then finally auctions and market design. Students who want to only dip their feet can opt out of later modules.

"Spamann, who also earned a master’s and Ph.D. in economics from Harvard and practiced briefly as an M&A attorney, says his background in economics informs his approach to corporate finance and how he teaches the subject."

Spamann and Guhan Subramanian also have a casebook for sale: here's the Amazon link.

Market design at Harvard Business School

Here's the announcement of a new HBS course on market design:

Making Markets

Course Number 1764
Professor Thomas R. Eisenmann
Associate Professor Scott Duke Kominers
Spring; Q3Q4; 3 credits
24 sessions
Paper
Markets are everywhere - and where they’re not, you can build them!

Career Focus

Over the past twenty years, entrepreneurs have created and captured enormous value by launching new marketplaces. Examples include Airbnb, Alibaba, ClassPass, Craigslist, eBay, eHarmony, Etsy, Gerson Lehrman Group, Google, IEX Group, Lending Club, Kickstarter, OpenTable, Rakuten, Uber, Upwork, and many more.
Making Markets (M²) is intended for students who want to manage in marketplace environments and remedy market failures by building new platforms and marketplaces from scratch or by redesigning existing ones - or who want to advise or invest in entrepreneurs who pursue such opportunities.

Educational Objectives

Students will learn how to identify market failures and determine when those failures create opportunities to launch or redesign marketplaces.
First, we will explore how markets function and what makes them fail. Next, we will examine how effective marketplace design-or redesign-can address market failures and improve efficiency, liquidity, and fairness. Then, we will take the entrepreneur’s perspective, studying the key barriers to organizing new marketplaces and devising strategies for overcoming them. Along the way, we will pay special attention to settings in which marketplaces create more value for transaction partners than relying only on unmediated exchanges. As we will see, marketplace design can often “square the circle,” solving seemingly intractable problems simply by reducing transaction costs or barriers to entry.
Case contexts will range from ultra-local (e.g., the HBS EC course lottery) to truly global (e.g., container shipping); will examine private and public/social enterprise settings; will profile both online and offline marketplaces; and will span all stages of marketplace launch and development.

Course Content

Through case studies, simulations, and the occasional interactive lecture, M² will examine the design, launch, and management of marketplaces and marketplace platforms. Core lessons include:
  • The Structure and Purposes of Markets: Markets create value by enabling parties to execute mutually beneficial transactions - exchanging goods, say, or sharing ideas. They are everywhere that transacting parties face incentives - from classic contexts like financial or product markets to dating, recruiting, and the sharing economy.
    Some markets are completely unstructured, but most are subject to at least some rules that shape participation. In this course, we will focus in particular on markets that are organized through marketplaces that combine rules for participation with infrastructure to facilitate interactions and transactions.
  • Common Sources of Market Failure: In many markets, institutional frictions combine with incentives to produce suboptimal outcomes - socially wasteful transactions occur, or productive ones do not. When such market failures occur, entrepreneurial opportunities arise: reshaping the market to improve efficiency creates value that can be captured(!).
    To understand how to fix markets, however, we must first understand how and why market failures occur. The course will classify different types of market failures, and highlight entrepreneurial responses to each.
  • Strategies for Launching and Managing Marketplaces: When launching a marketplace or other market intervention, it is essential to mobilize a critical mass of market participants so that there is enough liquidity for valuable transactions to occur. Once running, a marketplace must maintain balance between its supply and demand sides, or else participants may leave to transact elsewhere. Yet at the same time, marketplaces must avoid crowding that makes it hard for participants to find high-value transaction partners.
    The course will provide strategies for promoting participation and trust in marketplaces, especially early on. Then, we will learn techniques for growing marketplaces, and combating the problems that marketplaces face at scale, such as congestion, “unraveling” (e.g., when recruiters pressure candidates with early and exploding offers), and the risk of disintermediation.
  • Types of Marketplace Mechanisms: Markets work in many different ways. Some compel participants to seek out their own transaction partners; others use centralized transaction discovery and execution systems like auctions and recommendation algorithms. The mechanisms that a marketplace uses to identify and process transactions can be the difference between success and failure.
    Choosing among marketplace mechanisms requires careful attention to market participants’ needs and transaction attributes. The course will provide guidelines for adopting mechanisms best suited for different market contexts.

Incentives in Computer Science--Tim Roughgarden

There was a time when only economists worried about incentives, but as this great looking computer science course by Tim Roughgarden shows, that time is long past...

CS 269I: Incentives in Computer Science



Instructor:
  • Tim Roughgarden (Office hours (note new time): Mondays 12:15-1:15 PM, Gates 474. Email: tim@cs.stanford.edu.)

Prerequisites: Mathematical maturity at the level of undergraduate algorithms (CS161). Programming maturity at the level of 106B/X.
Course Description: Many 21st-century computer science applications require the design of software or systems that interact with multiple self-interested participants. This course will provide students with the vocabulary and modeling tools to reason about such design problems. Emphasis will be on understanding basic economic and game theoretic concepts that are relevant across many application domains, and on case studies that demonstrate how to apply these concepts to real-world design problems. Topics include auction and contest design, equilibrium analysis, cryptocurrencies, design of networks and network protocols, matching markets, reputation systems, and social choice. Possible case studies include BGP routing, Bitcoin, eBay's reputation system, Facebook's advertising mechanism, Mechanical Turk, and dynamic pricing in Uber/Lyft.
General references: Twenty Lectures on Algorithmic Game Theory, Cambridge University Press, 2016. See also the Amazon page.
  • This textbook is based on the course CS364A. The overlap with 269I will be roughly 20-25%. Though if you enjoy this course, you're likely to also enjoy many of the topics in this book.
The following collection is older and targeted more to researchers than to students, but is still useful for several topics.
