We investigate Italy's centralized teacher assignment system where teachers can rank "geographical regions", leading to ties in their rank order lists (ROLs). We show that the way ties in teachers' ROLs are resolved in the current assignment mechanism ...

The arrival of the gig economy has led to an unprecedented explosion of person-to-person task outsourcing: driving, food pickup, and shopping can all be done by someone other than the consumer. Such outsourcing potentially creates new challenges for gig ...

The use of product reviews in online platforms is ubiquitous and it is well established that reviews play a significant role on customer purchase decisions. The process in which reviews impact product purchases can be seen as a problem of social learning,...

Standard game-theoretic analysis yields highly incomplete descriptions of behavior in complex games of complete information. A key part of the reason is that standard models do not account for the role of complexity in shaping players' strategic ...

We study the impact of diversifying recommendations for inclusivity on one of the largest visual content discovery platforms in the world, Pinterest. Pinterest re-designed its recommendation systems to improve the representation of all skin tones in ...

Robust aggregation integrates predictions from multiple experts without knowledge of the experts' information structures. Prior work assumes experts are Bayesian, providing predictions as perfect posteriors based on their signals. However, real-world ...

We derive robust predictions in games involving flexible information acquisition, also known as rational inattention (Sims 2003). These predictions remain accurate regardless of the exact specification of players' learning abilities. Compared to ...

In this paper, we analyze a novel information-sharing policy to reduce stockouts and improve performance on online grocery retail platforms. Stockouts are particularly relevant to our setting, as online platforms lack control over retailers' inventory ...

The increasingly prevalent "fulfillment by platform" practice in the digital economy (e.g, Fulfillment by Amazon launched in 2006, JD marketplace in 2010, Fulfilled by Sears in 2013, Fulfillment by Shopee in 2022) presents platforms with the unique ...

We model the problem facing a policymaker who must allocate rapid rehousing support to people experiencing homelessness and wishes to minimize the steady-state size of the homeless population. Typically, support is given to the most vulnerable applicants,...

We study Prioritized Selection Problems in which an organization is presented with a set of individuals, and must choose which subset to accept. The organization makes a selection based on a priority ranking of individuals as well as other observable ...

Food waste and food insecurity are two closely related pressing global issues. Food rescue organizations worldwide run programs aimed at addressing the two problems. In this paper, we partner with a non-profit organization in the state of Indiana that ...

Maritime transportation is critical for the global economy, with about 90% of goods traded by sea and volumes expected to triple by 2050. Despite rising demand, 40% to 50% of total miles are sailed empty (known as ballasting), causing significant ...

The adoption of Artificial Intelligence (AI) for hiring processes is often impeded by a scarcity of comprehensive employee data. We hypothesize that the inclusion of behavioral measures elicited from applicants can enhance the predictive accuracy of AI ...

We analyze a problem of revealed preference given state-dependent stochastic choice data in which the payoff to a decision maker (DM) only depends on their beliefs about posterior means. Often, the DM must also learn about or pay attention to the state; ...

How should an expert send forecasts to maximize her utility subject to passing a calibration test? We consider a dynamic game where an expert sends probabilistic forecasts to a decision maker. The decision maker uses a calibration test based on past ...

In the video streaming market, streaming services use exclusive contracts to differentiate their content offerings and soften competition, while studios leverage these contracts to negotiate higher licensing fees against streaming services. I investigate ...
