Devising optimal criteria for federal fiscal transfers to reduce fisca
l imbalances across the states has always been a demanding job in Indi
a. In particular, two aspects that have become perennial sources of co
ntroversy are: the disintegrated componentwise approach, and the near-
subjective assignment of weights to factors determining the horizontal
shares of states Given that the reduction of horizontal fiscal inequi
ty is an important objective of the federal transfers, the study propo
ses a fiscal behavioural model to help identification of the criteria
and derive weights for deciding the revenue shares, based on their obs
erved degree of association with the fiscal balance of states. The app
roach is illustrated by estimating the model using panel data.
