A sender sends a signal about a state to a receiver who takes an action that determines a payoff. A moderator can block some or all of the sender's signal before it reaches the receiver. When the moderator's policy is transparent to the receiver, the moderator can improve the payoff by blocking...

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 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...

Operation Warp Speed (OWS) was a U.S. government-led program to accelerate the development, production, and administration of COVID-19 vaccines. The program cut the typical ten-year timeline needed to develop a new vaccine down to ten months and began vaccinating vulnerable populations within a...

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...

The Covid-19 pandemic has brought renewed attention to rationing guidelines for scarce medical resources. This paper describes the benefits of using a reserve system over a priority system in operationalizing compromises between certain ethical goals. In the last two years, more than a dozen...

Blockchain consensus is a state whereby each node in a network agrees on the current state of the blockchain. Existing protocols achieve consensus via a contest or voting procedure to select one node as a dictator to propose new blocks. However, this procedure can still lead to potential attacks...

We review economic arguments for using public policy to accelerate vaccine supply during a pandemic. Rapidly vaccinating a large share of the global population helps avoid economic, mortality, and social losses, which in the case of Covid-19 mounted into trillions of dollars. However,...

School assignment in Boston and New York City came to national attention in the 1970s as courts across the country tried to integrate schools. Today, district-wide choice allows Boston and New York students to enroll far from home, perhaps enhancing integration. Urban school transportation is...

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...
