We propose a pseudo-market solution to resource allocation problems subject to
constraints. Our treatment of constraints is general: including bihierarchical constraints due …

Interdistrict school choice programs—where a student can be assigned to a school outside
of her district—are widespread in the US. We introduce a model of interdistrict school choice …

Stability and “no justified envy” are used almost synonymously in the matching theory
literature. However, they are conceptually different and have logically separate properties …

Several structural results for the set of competitive equilibria in trading networks with frictions
are established: The lattice theorem, the rural hospitals theorem, the existence of side …

In this paper, we consider a multi-modal mobility system of travelers each with an individual
travel budget, and propose a game-theoretic framework to assign each traveler to a" mobility …

The classic two-sided many-to-one job matching model assumes that firms treat workers as
substitutes and workers ignore colleagues when choosing where to work. Relaxing these …

We consider a matching with contracts model in which buyers face financial constraints. In
this model, a competitive equilibrium may fail to exist. We therefore propose the new notion …

We study two-sided many-to-one matching markets with transferable utilities, eg, labor and
rental housing markets, in which money can exchange hands between agents, subject to …

We provide conditions under which a market mechanism can be used to allocate indivisible
goods efficiently. We consider an economy with no transfers and show the existence and …

I study the relationship between diversity preferences and the choice rules implemented by
institutions, with a particular focus on the affirmative action policies. I characterize the choice …
