Substitution Effect through Fiscal Transfers?!

Whether the results of fiscal transfers have positive or negative implications depends upon the incentives that transfer systems create for both central and local governments. The complexity and ambiguity of the relationship between fiscal transfers and tax revenues of local governments is one of the main causes why research projects, even in the same country, come to different results. This investigation is seriously questioning the often stated substitution effect based only on an analysis of aggregated data and finally rejects in the qualitative part of this research (using survey techniques) a substitution effect in the majority of the assessed municipalities.
