Optimal Urban Employment Policies: Notes on Calvo and Quibria
证明，在包含城市工会和非正规部门的模型中，对城市雇主征收收入中性的就业税补贴组合可以改善就业，并说明广义哈里斯-托达罗模型如何解释这一反直觉结果。
We show that Quibria's insightful observation on the efficacy of urban policy in a model with an urban trade union and an urban informal sector holds, but with a revenue‐neutral employment tax‐subsidy combination levied on the urban employer. We also draw the relevance of the generalized Harris–Todaro model in providing intuition for the validity of this surprising result.
