Fiscal Equalization and Tax Enforcement Timm Bönke, Beate Jochimsen, Carsten Schröder In: German Economic Review 18 (2017), 3, S. 377-409

Abstract:

In many countries organized as federations, fiscal equalization schemes have been implemented to mitigate vertical or horizontal imbalances. Such schemes usually imply that the member states of the federation can only partly internalize (marginal) tax revenue before redistribution. Aside from the internalized marginal revenue, referred to as the marginal tax-back rate, the remainder is redistributed. We investigate the extent to which state-level authorities in such federation under-exploit their tax bases. By means of a stylized model, we show that the member states have an incentive to align the effective tax rates on their residents with the level of the marginal tax-back rate. We empirically test the model using state-level and micro-level taxpayer data, OLS regressions and natural experiments. Our empirical findings support the results from our theoretical model. Particularly, we find that states with a higher marginal tax-back rate exploit the tax base to a higher extent.
