This paper extends pre-existing results concerning voluntary private funding of public goods. The assumption that individuals care about themagnitude of their own contributions only insofar as these contributions affect the aggregate level of expenditures is shown to have untenable implications. The analysis suggests that a reexaminationof the factors that motivate individuals to make contributions is in order. Copyright 1986 by American Economic Association.
