We analyze a theoretical model in which entrepreneurs’ property rights are threatened by “raiders” who can challenge them to a contest for control of their firms. Entrepreneurs have heterogeneous productivity, and decide how much capital to invest before raiders decide whom to attack. In...

We study priority-based assignment problems with distributional and diversity objectives. Our work provides an axiomatic characterization of a general class of choice rules which are based on type-specific reserves and quotas. The choice rules in the class differ by the order in which applicants...

We study the problem of allocating COVID-19 vaccines or other scarce and heterogeneous medical resources to patients. We develop algorithms for maximizing aggregate match-effectiveness subject to fairness and distributional constraints. Our solution uses a novel cutoff characterization result...

In centralized allocation problems participants have incomplete information about each others’ types. Hence, the designer may deviate from the announced allocation mechanism without the participants being able to detect these deviations. In this paper, I develop a theory of transparency in...

School districts commonly ration public school seats based on students preferences and priorities. Priorities reflect the school districts’ objectives for reducing busing costs (walk-zone priority) or utilizing siblings’ learning spillovers (sibling priority). Our work develops a simple...

In priority-based matching problems, there is a trade-off between efficiency andreducing justified-envy. We show that finding an efficient and justified-envy minimalmatching is an NP-hard problem when objects have weak priority rankings. Consequently, we focus on resolving the trade-off in a...

Proponents of school choice argue that it improves educational outcomes by allowing parents to self-select into schools that are most effective for their children. Contrary to these arguments, empirical evidence suggests that parents may not incorporate school effectiveness or match quality when...
