Atypicality and the Natural Vacancy Rate Hypothesis
基于自然空置率假说，构建并检验了租金变化模型，发现公寓单元的非典型性越高，其自然空置率也越高，整体自然空置率估计为6.5%。
This paper formulates and tests a model of rent change based on the natural vacancy rate hypothesis. It incorporates the Haurin [6] hypothesis in which the natural rate for particular units is determined by their atypicality. Estimates of the model indicate a natural rate of 6.5%. However, the rate is shown to vary systematically across individual units: the more atypical an apartment unit, the higher the natural rate.
