Pair rationality and top trading cycles on single-peaked and single-dipped domains
Özgün Ekici, M. Bumin Yenmez
In a recent study, Ekici and Yenmez (2026) characterize top trading cycles (TTC) on the unrestricted domain by strategy-proofness, individual rationality, and pair rationality, unc…
Minimally rational reallocation of objects
Özgün Ekici, M. Bumin Yenmez
Matching theory has largely evolved around two canonical rules: deferred acceptance (DA) in the marriage problem and top trading cycles (TTC) in the object reallocation problem. Al…
Priority Blockers: Welfare and Incentives in Matching under General Constraints
Lars Ehlers, M. Bumin Yenmez
Institutions often face constraints richer than a single capacity. Protecting the priority of a student who cannot be accommodated may then block a lower-priority student who fits.…
Diversity as Majorization
Federico Echenique, Teddy Mekonnen, M. Bumin Yenmez
How should institutions compare group diversity, and which group should they select when they value diversity and merit? We take a target-based approach that evaluates the entire g…
Acceptant Expansions of Path-Independent Choice Rules
Christopher P. Chambers, M. Bumin Yenmez
A choice rule is -acceptant if it chooses alternatives from each set . We show that a path-independent rule of maximum cardinality at most need not have a…
Rawlsian equity: a new notion of fairness for the assignment problem
Özgün Ekici, Sinan Ertemel, M. Bumin Yenmez
We introduce Rawlsian equity, a notion of fairness for allocating indivisible objects among agents without object-specific entitlements. Rawlsian equity requires that an object not…
Distributional Preferences for Market Design
Federico Echenique, Teddy Mekonnen, M. Bumin Yenmez
Institutions selecting students, employees, or members value both about who is selected and the resulting group's composition. We study ``distributional'' preferences over group co…
Endogenous Inequality Aversion: Decision criteria for triage and other ethical tradeoffs
Federico Echenique, Teddy Mekonnen, M. Bumin Yenmez
Medical ``Crisis Standards of Care'' call for a utilitarian allocation of scarce resources in public emergencies, whereas standards of care under normal conditions place relatively…
Diversity in Choice as Majorization
Federico Echenique, Teddy Mekonnen, M. Bumin Yenmez
We propose a framework that uses majorization to model diversity and representativeness in school admissions. We generalize the standard notion of majorization to accommodate arbit…
Rationalizing Path-Independent Choice Rules
Koji Yokote, Isa E. Hafalir, Fuhito Kojima +1
Path independence is arguably one of the most important choice rule properties in economic theory. We show that a choice rule is path independent if and only if it is rationalizabl…
Market Design with Distributional Objectives
Isa E. Hafalir, Fuhito Kojima, M. Bumin Yenmez +1
We provide optimal solutions to an institution that has distributional objectives when choosing from a set of applications based on merit (or priority). For example, in college adm…
Efficient Market Design with Distributional Objectives
Isa E. Hafalir, Fuhito Kojima, M. Bumin Yenmez
Given an initial matching and a policy objective on the distribution of agent types to institutions, we study the existence of a mechanism that weakly improves the distributional o…
Market Design with Deferred Acceptance: A Recipe for Policymaking
Battal Doğan, Kenzo Imamura, M. Bumin Yenmez
We introduce a method to derive from a characterization of institutional choice rules (or priority rules), a characterization of the Gale-Shapley deferred-acceptance (DA) matching…
Constitutional Implementation of Affirmative Action Policies in India
Tayfun Sonmez, M. Bumin Yenmez
India is home to a comprehensive affirmative action program that reserves a fraction of positions at governmental institutions for various disadvantaged groups. While there is a Su…
Fair Allocation of Vaccines, Ventilators and Antiviral Treatments: Leaving No Ethical Value Behind in Health Care Rationing
Parag A. Pathak, Tayfun Sönmez, M. Utku Ünver +1
A priority system has traditionally been the protocol of choice for the allocation of scarce life-saving resources during public health emergencies. Covid-19 revealed the limitatio…
Interdistrict School Choice: A Theory of Student Assignment
Isa E. Hafalir, Fuhito Kojima, M. Bumin Yenmez
Interdistrict school choice programs-where a student can be assigned to a school outside of her district-are widespread in the US, yet the market-design literature has not consider…
