We show that spatial equilibrium conditions in workhorse models of quantitative spatial economics (QSE) can be generated by the McFadden (1974) model together with the condition that the individual choice probability of a region equals the population share of that region. Thus, recent models of QSE and one of the oldest location choice models can rationalize the same change in equilibrium following shocks to economic fundamentals. However, their welfare implications—even conditional on the same change in equilibrium—may differ, depending on the specification of preferences and on the type of shocks we consider.

关于定量空间经济模型

我们表明，McFadden（1974）模型可以产生量化空间经济学（QSE）的主力模型中的空间均衡条件，以及一个区域的个人选择概率等于该区域的人口份额的条件。因此，最近的QSE模型和最古老的区位选择模型之一可以合理化经济基本面遭受冲击后的均衡变化。但是，它们的福利含义（甚至以平衡的相同变化为条件）可能会有所不同，具体取决于偏好的规范和我们考虑的冲击类型。
