Unravelling heterogeneities in taxable agglomeration rents: a lens through location elasticity
改进了空间自回归固定效应模型，利用西班牙7141个市镇2009-2021年的面板数据，发现可征税集聚租金仅存在于少数城市，并探讨了马德里的特殊案例。
The approaches used to assess the existence of taxable agglomeration rents (TARs) impose the fact that all jurisdictions face the same TARs elasticity. This paper reassess the TARs phenomenon in Spain, proposing a modification of the workhorse spatial autoregresive model with fixed effects (SAR-FE) which controls for heterogeneities in the effect of agglomeration on business tax rates using functional urban areas. The estimation of the model using a panel of 7141 municipalities from 2009 to 2021 shows that TARs are only confirmed for a small number of urban municipalities. Madrid emerges as a striking result, and we point out a potential explanation by considering who are its competitors.
