How should authorities that care about match quality and diversity allocate resources in the face of uncertainty? We introduce adaptive priority mechanisms (APM) that prioritize agents based on their scores and characteristics. We show that APM uniquely implement the ex post optimal allocation....

Kidney exchange emerges as a pioneering application in the early stages of market design. In contrast to most other successful applications in the field, where design economists primarily serve as consultants to decision-makers, in the context of kidney exchange, they assumed the role of...

We conduct an incentivized lab experiment to test participants' ability to understand the DA matching mechanism and the strategyproofness property, conveyed in different ways. We find that while many participants can (using a novel GUI) learn DA's mechanics and calculate its outcomes, such...

A menu description presents a mechanism to player i in two steps. Step (1) uses the reports of other players to describe i's menu: the set of i's potential outcomes. Step (2) uses i's report to select i's favorite outcome from her menu. Can menu descriptions better expose strategyproofness,...

We study the volunteer's dilemma in environments with heterogeneous preferences and private information. We characterize the efficiency properties of equilibrium, which is a departure from all the previous literature that focuses only on the probability of group success. While the probability of...

We propose a sufficient statistic for designing AI information-disclosure and selective automation policies. The approach allows for endogenous and biased beliefs, and effort crowd-out, without using a structural model of human decision-making. We deploy and validate our approach in a...

We examine whether large-scale information interventions can improve college application outcomes in a centralized admissions system. Using nationwide surveys from Chile, we document widespread information frictions and frequent application mistakes, such as omitting attainable preferred...

Sequential choices are ubiquitous in daily life, yet making optimal decisions in such settings--where properly accounting for option value is crucial--can be challenging. This paper provides field experimental evidence on the neglect of option value in high-stakes decisions and quantifies the...

We derive the optimal funding mechanism to incentivize development and production of vaccines against diseases with epidemic potential. In the model, suppliers' costs are private information and investments are noncontractible, precluding cost-reimbursement contracts, requiring fixed-price...

Can incorporating expectations-based-reference-dependence (EBRD) considerations reduce seemingly dominated choices in the Deferred Acceptance (DA) mechanism? We run two experiments (total N = 500) where participants are randomly assigned into one of four DA variants--{static, dynamic} * {student...
