Intergovernmental grants have been conventionally explained on the bas
is of either equity/efficiency and/or institutional considerations. Th
is paper seeks to model Australian intergovernmental grants by includi
ng both traditional public finance variables and public choice influen
ces; that is, grants are used by federal government politicians to pur
chase political capital, thereby enhancing their own chances of reelec
tion. The models employed in this paper are tested for six Australian
states for the period 1981-82 to 1991-92 using unsystematic grant tran
sfers. The results provide support for these public choice considerati
ons, and highlight the importance of incorporating institutional facto
rs and controlling for misspecification in the error structure in esti
mates of this type.
