Coordination of Fiscal Policy among a Subset of Countries
构建了一个包含工会工资谈判导致失业的一般均衡模型，分析不同国家群体间财政政策协调的福利效果，发现所有国家协调最优、无协调次优、同类产品国家协调仅第三优，但后者仍有协调动机。
A general equilibrium model, with unemployment due to labor unions having wage bargaining power, is set up. There are a number of produced goods which are imperfect substitutes in consumption and there are a number of countries producing each good. It is shown that coordination of fiscal policy among all countries is first best, no coordination at all is second best, whereas coordination among countries producing the same type of good (i.e., countries which are 'most alike') is only third best. In spite of this, countries producing the same good have an incentive to coordinate their policies. Copyright 1996 by The editors of the Scandinavian Journal of Economics.
