• Resumen

  • The foot-loose capital (FC) models predict that agglomeration forces create rents for the mobile factor (capital), which can be easily taxed, and thus higher equilibrium tax rates are expected. This paper uses a highly flexible econometric specification (P-Spline spatial autoregressive model, PS-SAR) to look at the relationship between tax rates and agglomeration economies in Spain over the period 2013-2020. Our results show the existence of a minimum level of agglomeration economies that are required to find taxable agglomeration rents. This outcome calls for a reassessment of the linear FC models to disentangle which mechanisms might lead to these phenomena.
