Measuring the diffusion of housing prices across space and over time: Replication and further evidence
复制了Brady（2011）关于房价空间扩散的研究，发现不同房价指数会导致模型设定和估计结果差异，并进行了更长时间的稳健性检验。
Summary Brady ( Journal of Applied Econometrics , 2011, 26 (2), 213–231) studies how fast and how long a change in housing prices in one region affects its neighbors by estimating the impulse response functions using a spatial autoregressive model (SAR). This paper replicates Brady's empirical results, but reports different SAR test statistics. Additional robustness checks are conducted by analyzing three different housing price indexes covering a more extensive period. Analysis shows that the model specifications and model estimates vary with the housing price indexes.
