Nicht alle Güter werden über einen Preismechanismus auf Märkten gehandelt. Angebot und Nachfrage von Plätzen an Schulen und Universitäten, die Zuweisung von Organen bei Lebendspendern und die Partnerwahl vollziehen sich nach anderen Regeln. Wie diese Regeln gestaltet sein müssen, um zu...

I provide a brief introduction to the early literatures on Matching, Auctions, and Market Design.The design of matching markets and auctions has brought economic theory and practice together. Indeed, this is an area where microeconomic theory has had its largest direct impact. This is in part...

In many markets, sellers advertise their good with an asking price. This is a price at which the seller is willing to take his good off the market and trade immediately, though it is understood that a buyer can submit an offer below the asking price and that this offer may be accepted if the...

We study manipulability of stable matching mechanisms and show that manipulability comparisons are equivalent to preference comparisons: for any agent, a mechanism is more manipulable than another if and only if this agent prefers the latter to the former. In particular, this implies that no two...

We characterize choice rules for schools that regard students as substitutes while expressing preferences for a diverse student body. The stable (or fair) assignment of students to schools requires the latter to regard the former as substitutes. Such a requirement is in conflict with the reality...

Each year, over a hundred thousand defendants who are too poor to pay for a lawyer are assigned counsel. Existing procedures for making such assignments are essentially random and have been criticized for giving indigent defendants no say in choosing the counsel they are assigned to. In this...

We provide a real-life application of a large scale affirmative action policy in school choice in the context of engineering school admissions in India where students not only care about what program they are matched to but also what type of seat category they are admitted under. We explain the...

We investigate the teacher assignment problem where one has to assign both newly tenured teachers without an initial assignment and tenured teachers with an initial position. Each school has a priority ordering over the teachers. In this framework, there is no mechanism that is both i)...

Divided enrollment systems cause school assignments to be unfair and wasteful. Iterative version of the student-optimal stable mechanism (I-SOSM), proposed by Manjunath and Turhan (2016), achieves individually rational and fair assignments in such partitioned school choice markets for any number...
