Farsighted Stability for Roommate Markets

By: Bettina-Elisabeth Klaus, Flip Klijn and Markus Walzl

Using a bi-choice graph technique (Klaus and Klijn, 2009), we show that a matching for a roommate market indirectly dominates another matching if and only if no blocking pair of the former is matched in the latter (Proposition 1). Using this characterization of... View Details

The Effects of a Central Clearinghouse on Job Placement, Wages, and Hiring Practices

By: Muriel Niederle and Alvin E. Roth

New gastroenterologists participated in a labor market clearinghouse (a "match") from 1986 through the late 1990s, after which the match was abandoned. This provides an opportunity to study the effects of a match by observing the differences in the outcomes and... 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

Stability, Strategy-Proofness, and Cumulative Offer Mechanisms

By: John William Hatfield, Scott Duke Kominers and Alexander Westkamp

We consider the setting of many-to-one matching with contracts, where firms may demand multiple contracts but each worker desires at most one contract. We introduce three novel conditions—observable substitutability, observable size monotonicity,... View Details

Stability and Nash Implementation in Matching Markets with Couples

By: Claus-Jochen Haake and Bettina-Elisabeth Klaus

We consider two-sided matching markets with couples. First, we extend a result by Klaus and Klijn (2005, Theorem 3.3) and show that for any weakly responsive couples market there always exists a "double stable" matching, i.e., a matching that is stable for the couples... 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

Smith and Rawls Share a Room: Stability and Medians

By: Bettina-Elisabeth Klaus and Flip Klijn

We consider one-to-one, one-sided matching (roommate) problems in which agents can either be matched as pairs or remain single. We introduce a so-called bi-choice graph for each pair of stable matchings and characterize its structure. Exploiting this structure we... View Details

Matching and Market Design

By: Muriel Niederle, Alvin E. Roth and Tayfun Sonmez

Matching is the part of economics concerned with who transacts with whom and how. Models of matching, starting with the Gale-Shapley deferred acceptance algorithm, have been particularly useful in studying labour markets and in helping design clearinghouses to fix... View Details

Matching in Networks with Bilateral Contracts

By: John William Hatfield and Scott Duke Kominers

We introduce a model in which firms trade goods via bilateral contracts which specify a buyer, a seller, and the terms of the exchange. This setting subsumes (many-to-many) matching with contracts, as well as supply chain matching. When firms' relationships do not... View Details

Hidden Substitutes

In this paper, we show that preferences exhibiting some forms of complementarity in fact have an underlying substitutable structure. Specifically, we show that some preferences that are not substitutable in the setting of many-to-one matching with contracts become... View Details
