We study priority-based matching markets with public and private endowments. We show that efficiency-adjusted deferred acceptance (EADA) is justified-envy minimal in the class of efficient mechanisms, while Top trading cycles (TTC) and other popular mechanisms are not. Our findings highlight...

A growing body of evidence suggests that decision-makers fail to account for correlation in signals that they receive. We study the relevance of this mistake in students' interactions with school- choice matching mechanisms. In a lab experiment presenting simple and incentivized school-choice...

Although many centralized school assignment systems use strategically simple mechanisms, applicants often make dominated choices. Using administrative data from Hungary, we show that many college applicants forgo the free opportunity to receive a tuition waiver. Using two empirical strategies,...

In a centralized marketplace that was designed to be simple, we identify participants whose choices are dominated. Using administrative data from Hungary, we show that college applicants make obvious mistakes: they forgo the free opportunity to receive a tuition waiver worth thousands of...

We study college admissions markets, where colleges offer multiple funding levels. Colleges wish to recruit the best-qualified students subject to budget and capacity constraints. Student-proposing deferred acceptance is stable and strategy-proof for students, but the set of stable allocations...

We review the process of redesigning the Israeli Psychology Masters Match (IPMM), with special attention given to the fellowships granted by the departments and the interplay between different programs within the same department. These features make the IPMM a two-sided matching with contracts...

We present direct field evidence of preference misrepresentation under deferred acceptance. A large fraction of highly educated participants, who had been informed about the strategy-proof nature of the mechanism in numerous ways, failed to play truthfully: they ranked a non-funded position...

Stability and "no justified envy" are used almost synonymously in the matching theory literature. However, they are conceptually different and have logically separate properties. We generalize the definition of justified envy to environments with arbitrary school preferences, feasibility...
