A public choice approach is used to examine the level of a tax-finance
d grant chosen by a cohort, allowing for a wide range of interdependen
cies, including the government's budget constraint. The existence of a
n externality is necessary, but not sufficient, for support of a grant
. It is shown that a majority voting equilibrium exists. Comparative s
tatic analyses are carried out using a minimum of assumptions about th
e structure of the model. An increase in government expenditure for no
n-higher education purposes is associated with an increase in the pref
erred grant, while an increase in private returns to education reduces
the grant.
