Foundations of pseudomarkets: Walrasian equilibria for discrete resources

Miralles Asensio, Antonio; Pycia, Marek - 2021 - This draft: May 2021

We study the assignment of discrete resources in a general model encompassing a wide range of applied environments, such as school choice, course allocation, and refugee resettlement. We allow single-unit and general multi-unit demands and any linear constraints. We prove the Second Welfare...
