Randomness and Fairness in Two-Sided Matching with Limited Interviews

Authors: Hedyeh Beyhaghi and Éva Tardos

Published in: LIPIcs, Volume 185, 12th Innovations in Theoretical Computer Science Conference (ITCS 2021)

Abstract
We study the outcome in a matching market where both sides have limited ability to consider options. For example, in the national residency matching program, doctors are limited to apply to a small set of hospitals, and hospitals are limited by the time required to interview candidates. Our main findings are the following: (1) In markets where jobs can only consider a limited number of candidates for interview, it increases the size of the resulting matching if the system has a limit on the number of applications a candidate can send. (2) The fair system of all applicants being allowed to apply to the exact same number of positions maximizes the expected size of the matching. More particularly, starting from an integer k as the number of applications, the matching size decreases as a few applicants are allowed to apply to one additional position (and then increases again as they are all allowed to apply to k+1). Although it seems natural to expect that the size of the matching would be a monotone increasing and concave function in the number of applications, our results show that neither is true. These results hold even in a market where a-priori all jobs and all candidates are equally likely to be good, and the judgments of different employers and candidates are independent. Our main technical contribution is computing the expected size of the matching found via the deferred acceptance algorithm as a function of the number of interviews and applications in a market where preferences are uniform and independent. Through simulations we confirm that these findings extend to markets where rankings become correlated after the interviews.

Interface of Computation, Game Theory, and Economics (Dagstuhl Seminar 13161)

Authors: Sergiu Hart, Éva Tardos, and Bernhard von Stengel

Published in: Dagstuhl Reports, Volume 3, Issue 4 (2013)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 13161 "Interface of Computation, Game Theory, and Economics". The workshop was strongly interdisciplinary, on the leading edge of current topics generally connected to algorithmic game theory: Mechanism design and auctions, interactions in networks, social models, and dynamics and equilibrium in games and markets. We summarize these topics, give the talk abstracts, and comment on experiences related to the organization of the workshop.

07271 Summary – Computational Social Systems and the Internet

Authors: Peter Cramton, Rudolf Müller, Eva Tardos, and Moshe Tennenholtz

Published in: Dagstuhl Seminar Proceedings, Volume 7271, Computational Social Systems and the Internet (2007)

Abstract
The seminar "Computational Social Systems and the Internet" facilitated a very fruitful interaction between economists and computer scientists, which intensified the understanding of the other disciplines' tool sets. The seminar helped to pave the way to a unified theory of social systems on the Internet that takes into account both the economic and the computational issues---and their deep interaction.
