In a dynamic model of local government spending, this paper examines b
oth long-run and short-run effects of permanent federal grant changes
on local public investment and recurrent expenditures. It also utilize
s the Judd approach to quantify the short-run effects of temporary (cu
rrent and future) policy shocks. The interesting, perhaps surprising,
findings are: (1) a permanent increase in the matching grants for inve
stment and recurrent expenditures may accelerate or slow down public i
nvestment and (2) a current, temporary grant increase stimulates curre
nt public investment, but a temporary, future increase in the nonmatch
ing grant reduces current investment and raises current recurrent expe
nditures. (C) 1994 Academic Press, Inc.
