ABSTRACT
This study investigates the spatial heterogeneity of the flypaper effect in a sample of 2,451 Spanish municipalities over the period 2003–2015 by means of Bayesian spatial panel data econometric techniques including municipal and time-period fixed effects. In particular, we analyse how differences in the degree of political competition and the local governments’ monitoring and enforcement effort in tax collection affect the size of the flypaper effect. Our results suggest that municipalities with higher tax collection efficiency and where local governments have more political strength exhibit a lower flypaper effect.

Notes
1. See Hines and Thaler (Citation1995) or Inman (Citation2008) for an overview.
2. The estimation strategy for cross-section spatial models of Acosta (Citation2010) and Bastida, Guillamón, and Benito (Citation2013) is based on the IV estimator, which in the context of spatial regressions has as a main drawback the fact that the coefficient estimate of the spatial autoregressive term may fall outside its parameter space and it is usually less efficient (Elhorst and Fréret Citation2009).

4. In the case of Spain, intergovernmental grants are mainly unconditional and account for more than a third of municipal revenues on average.
5. In this setting is smoothed using a combination of values in neighbouring areas. The value of
is based on a cross-validation procedure where the score function
is minimised.
6. Using data on Peruvian municipalities, he finds that municipalities facing higher tax collection costs are more responsive to additional grants, which should increase the size of the FPE.
7. The use of political variables has forced us to restrict the panel data to the electoral years (i.e., 2003, 2007, 2011 and 2015). Therefore, our . This limited time dimension precludes us to employ a dynamic specification given that by construction we would lose one period leaving us with
, and such a short panel could yield very noisy estimates of both the temporal and the space-time diffusion parameters.
8. The first spatial weights matrix is based on the concept of first-order contiguity, according to which if jurisdictions
and
are physical neighbours and
otherwise. The definition of neighbouring regions used here is based on physical contiguity. To ensure that every region has at least one neighbour, we employ the Delaunay triangulation by constructing Voronoi polygons from the centroids of the sample municipalities using the Matlab function xy2cont.m developed by LeSage. See LeSage and Pace (Citation2009, 118) for further details. Secondly, several matrices based on inverse distance with cut-offs at different thresholds of distance in kilometres are introduced. In addition, power distance and exponential decay matrices with cut-offs at the first and second quartile are employed. Finally, k-nearest neighbours computed from the great circle distance between the centroids of the various jurisdictions are also considered.
9. The results are shown in Table A1 in the Appendix.
10. In order to save space, the results are not shown here but available upon request to the authors.
11. We use the tilde notation to distinguish them from the parameter estimates in Equations (5) and (12), given that to simulate the FPE conditional on we use the total effects implied by the Monte Carlo simulation of the partial derivative of the reduced form of the SDM in Equation (8).
12. A concern might arise as to whether our measure of tax collection efficiency may simply reflect higher per capita income of the local taxpayers, thus affecting the interpretation of the previous result. Nevertheless, this is not the case in our sample of municipalities as there is a negative but relatively weak correlation between these two variables (−0.31 with p-value 0.00).
