Dixit-Stiglitz-Krugman模型是新经济地理学中最基本的模型之一，它由名义工资方程描述。在给定工人分布的条件下，短期均衡由名义工资方程的解定义，我们得到了该模型短期均衡存在唯一的充分条件.我们构造了一个迭代方案，以获得数值短期平衡。对开展经济活动的地点总数没有限制。
The Dixit–Stiglitz–Krugman model is one of the most fundamental models in the new economic geography, and is described by the nominal wage equation. We obtain sufficient conditions for the existence and uniqueness of short-run equilibrium of this model, where a short-run equilibrium is defined by a solution of the nominal wage equation under the condition that the worker distribution is given. We construct an iteration scheme to obtain numerical short-run equilibria. No restriction is imposed on the total number of locations where economic activities are conducted.
