不可分资源市场中的经济干预政策:基于替代性条件的理论分析

Economic Intervention Policies in Markets for Indivisible Resources:Theoretical Analysis Anchored on the Substitutes Condition

在不可分资源市场中,工作单位在雇佣职工或购买物品时通常面临经济干预政策。考虑到替代性条件对于不可分资源市场中竞争性均衡存在性的关键作用,本文讨论了约束和财政转移政策两类代表性的干预政策对替代性条件的影响。当替代性条件在干预政策前成立,对于哪些约束和财政转移政策可以保护替代性条件,本文给出了一系列的刻画结论。当替代性条件在干预政策前可能不成立,本文给出的结论表明了如何通过适当的干预政策重建替代性条件。这些结论说明了干预政策将会如何影响不可分资源市场,并为政府制定干预政策提供了参考。

In markets for indivisible resources,firms often face economic intervention policies in hiring workers or buying goods.This paper discusses the effect of constraints and transfer policies-two kinds of representative intervention policies-on the substitutes condition,which is critical for the existence of competitive equilibria in markets for indivisible resources.When the substitutes condition is established before intervention policies,this paper gives a series of characterization conclusions about which kinds of constraints and transfer policies can preserve the substitutes condition.When the substitutes condition may fail before intervention policies,the conclusion given by this paper shows how to reestablish the substitutes condition using well-designed intervention policies.These conclusions explain how intervention policies impact markets for indivisible resource,and provide reference for the government to formulate reasonable intervention policies.
