Decentralized systems of government finance give rise to fiscal disparities
due to interjurisdictional variations in tax bases and expenditure needs.
Intergovernmental aid is used to address such disparities. This article exp
lores changes in local tax capacity and intergovernmental aid resulting fro
m urban shopping malls that extract retail sales and sales tax revenue away
from surrounding areas especially rural counties. A model is developed and
estimated to determine the impact of urban malls on local government sales
tax bases, controlling for sales tax rate differentials and other factors.
The results reveal a 15.9% decline in the sales tax base for counties in c
lose proximity to two new malls. The analysis is extended to examine impact
s of changing local tax capacity on state education aid Based on the progra
m considered here, less than 20% of the loss in own-source revenue is recov
ered through increased aid.
