On the existence of EFX allocations for goods

Theoretical Economics 2025-07-15 v1

Abstract

We consider a set EE of mm indivisible goods and a set NN consisting of n2n \geq 2 agents. The paper shows that if two agents have \textit{arbitrary} set monotonic valuation functions and the remaining agents have size monotonic valuation functions, then EFX allocations always exist.
