Optimizing Reserves in School Choice: A Dynamic Programming Approach

By: Franklyn Wang, Ravi Jagadeesan and Scott Duke Kominers

We introduce a new model of school choice with reserves in which a social planner is constrained by a limited supply of reserve seats and tries to find an optimal matching according to a social welfare function. We construct the optimal distribution of reserves via a... View Details

Landing the First Job: The Value of Intermediaries in Online Hiring

By: Christopher Stanton and Catherine Thomas

Online markets for remote labor services allow workers and firms to contract with each other directly. Despite this, intermediaries—called outsourcing agencies—have emerged in these markets. This paper shows that agencies signal to employers that inexperienced workers... View Details

Competition and Resource Sensitivity in Marriage and Roommate Markets

By: Bettina-Elisabeth Klaus

We consider one-to-one matching markets in which agents can either be matched as pairs or remain single. In these so-called roommate markets agents are consumers and resources at the same time. We investigate two new properties that capture the effect a newcomer has on... View Details

Stable Many-to-Many Matchings with Contracts

By: Bettina-Elisabeth Klaus and Markus Walzl

We consider several notions of setwise stability for many-to-many matching markets with contracts and provide an analysis of the relations between the resulting sets of stable allocations for general, substitutable, and strongly substitutable preferences. Apart from... View Details

Manipulability in Matching Markets: Conflict and Coincidence of Interests

We study comparative statics of manipulations by women in the men-proposing deferred acceptance mechanism in the two-sided one-to-one marriage market. We prove that if a group of women employs truncation strategies or weakly successfully manipulates, then all other... View Details

Unravelling in Two-Sided Matching Markets and Similarity of Preferences

By: Hanna Halaburda

This paper investigates the causes and welfare consequences of unravelling in two-sided matching markets. It shows that similarity of preferences is an important factor driving unravelling. In particular, it shows that under the ex-post stable mechanism (the mechanism... View Details

Refugee Resettlement

By: David Delacretaz, Scott Duke Kominers and Alexander Teytelboym

Over 100,000 refugees are permanently resettled from refugee camps to hosting countries every year. Nevertheless, refugee resettlement processes in most countries are ad hoc, accounting for neither the priorities of hosting communities nor the preferences of refugees... View Details

Deep Learning for Two-Sided Matching

By: Sai Srivatsa Ravindranatha, Zhe Feng, Shira Li, Jonathan Ma, Scott Duke Kominers and David Parkes

We initiate the use of a multi-layer neural network to model two-sided matching and to explore the design space between strategy-proofness and stability. It is well known that both properties cannot be achieved simultaneously but the efficient frontier in this design... View Details

Reserve Design: Unintended Consequences and the Demise of Boston's Walk Zones

By: Umut Dur, Scott Duke Kominers, Parag A. Pathak and Tayfun Sönmez

Admissions policies often use reserves to grant certain applicants higher priority for some (but not all) available seats. Boston’s school choice system, for example, reserved half of each school’s seats for local neighborhood applicants while leaving the other half... View Details

Testing Substitutability

By: John William Hatfield, Nicole Immorlica and Scott Duke Kominers

We provide an algorithm for testing the substitutability of a length-N preference relation over a set of contracts X in time O(|X|3⋅N3). Access to the preference relation is essential for this result: We show that a substitutability-testing algorithm with access only... View Details

Unraveling Results from Comparable Demand and Supply: An Experimental Investigation

By: Muriel Niederle, Alvin E. Roth and M. Utku Unver

Markets sometimes unravel, with offers becoming inefficiently early. Often this is attributed to competition arising from an imbalance of demand and supply, typically excess demand for workers. However this presents a puzzle, since unraveling can only occur when firms... View Details
