Housing and Tax Policy: Comment
指出Alpanda和Zubairy（2016）关于住房税收政策长期乘数的代码错误，修正后乘数几乎减半，并计算了短期乘数，发现其数值更低。
Abstract Alpanda and Zubairy (2016) examine the effects of permanent changes to four types of housing‐related tax policies in the context of a multiagent dynamic general equilibrium (DGE) model. They find long‐run tax multipliers that range from −2.21 to −1.53. However, we find an error in their codes that has a significant impact on the size of these multipliers. We correct their error and resimulate their model. The long‐run multipliers we find are reduced almost in half—they now range from −1.25 to −0.84. We also compute short‐run multipliers at a 20‐quarter horizon and find much lower multipliers, ranging between −0.14 and −0.02.
