Falsification-proof non-market allocation mechanisms

The paper examines allocation mechanisms that rely on manipulable characteristics and shows that naive optimal rules lead to falsification and inefficiency. It characterizes optimal falsification‑proof rules across various falsification technologies and identifies an honesty condition under which these rules solve the planner’s unconstrained problem of maximizing a weighted sum of allocative surplus and agents’ welfare.

Allocating Indivisible Goods to Strategic Agents: Pure Nash Equilibria and Fairness

The paper studies how to allocate indivisible goods to strategic agents with additive valuations without monetary transfers. It investigates whether mechanisms can guarantee pure Nash equilibria while ensuring fairness, focusing on envy‑freeness up to one good (EF1) and envy‑freeness up to any good (EFX). The authors show that the Round‑Robin algorithm yields EF1 allocations at every pure Nash equilibrium, and that a cut‑and‑choose algorithm for two agents produces EFX and maximin share fair allocations in equilibrium, a property absent in the non‑strategic setting.
