难民重新安置:一种机制设计方法

Refugee Relocation: A Mechanism Design Approach
The Economic Journal · 2024 · Martin Hagen

中文摘要

本文提出一种在欧盟内部分配难民的新机制。通常采用的强制难民配额做法遭到若干国家的强烈反对。我们的机制根据各国对移民的偏好来调整这些配额。所有国家均实现弱改善,即便它们并不进行在伦理上颇具争议的货币转移支付。我们将难民重新安置形式化建模为具有单峰偏好的分配问题。我们的“配额调整机制”是唯一同时满足防策略性、帕累托效率以及一种考虑了国家间不对称性的新型公平概念的机制。

Abstract

Abstract This paper introduces a new mechanism to distribute refugees within the European Union. The usual approach of assigning mandatory refugee quotas has been heavily opposed by several countries. Our mechanism adjusts these quotas to countries’ preferences on immigration. All countries become weakly better off, even though they do not exchange monetary transfers, which are ethically controversial. We formally model refugee relocation as a division problem with single-peaked preferences. Our ‘quota adjustment mechanism’ is the only one satisfying strategy-proofness, Pareto efficiency and a novel concept of fairness that takes account of the asymmetry across countries.
