Spatial equilibrium in deviations: An application to skill‐premium and skill‐mix heterogeneity
提出一种新的空间一般均衡线性表示方法，用局部百分比偏离对称基准来建模，并应用于解释技能溢价和技能组合的空间异质性，提供统一框架和实证检验方法。
Abstract In this paper, we propose a novel—and general‐purpose—modeling approach. We give a linear representation of the spatial general equilibrium, expressed in terms of local percentage deviations from the benchmark case of symmetry, where all the areas in the economy are taken to be initially identical. To illustrate the flexibility of our approach, we revisit the literature on the spatial heterogeneity of local skill premia and local skill mix. We show that our approach is able to encompass a variety of alternative explanations in a simple “unifying framework.” Finally, we exploit a graphical version of the model to show how to implement empirical tests.
