BEYOND GAPS AND IMBALANCES: RE‐STRUCTURING THE DEBATE ON INTERGOVERNMENTAL FISCAL RELATIONS

How do we know whether a country suffers from vertical fiscal imbalance (VFI)? What should be done about it? Academic appreciation of these issues in general, and the nature of political behaviour in particular, both have major implications for the way federations are fiscally structured. While the latter clearly is a problem of political negotiations, our focus is on the former, that is, conceptual clarity, which precedes meaningful negotiations. Thus, the paper aims to clarify the multiple usages of the symbolically loaded terms VFI and VFG (vertical fiscal gap) by critically engaging the fundamental assumptions and premises underlying these ostensibly similar notions. It proposes an alternative conceptual framework and introduces the concepts of vertical fiscal asymmetry (VFA) and vertical fiscal difference (VFD) that have the potential to better structure public debate on issues of vertical fiscal relations and stimulate a sensible appreciation of the problem and possible remedies.     

Mexican Municipalities and the Flypaper Effect

We investigate the phenomenon of flypaper effect and its relationship with the local tax effort by using a panel data comprising approximately 48 percent of the Mexican municipalities. Our estimations based on the fixed effect and difference GMM estimators confirm the existence of flypaper effect. Moreover, we find evidence to suggest that the richer municipalities are likely to experience substitution effect, i.e., the lower levels of tax effort. We also find that the magnitude of the flypaper effect is a decreasing function of the economic wellbeing of municipalities. This calls for an overhaul of the allocation mechanism of unconditional grants to the Mexican municipalities.
