Anthony de Jasay attempts to demonstrate that public goods can be supp
lied privately without loss of efficiency, since there may be enough p
eople willing to finance public-goods production voluntarily, even at
the risk of subsidizing free riders, rather than risk that public good
s will not be produced at all. Jasay's argument rests on the implausib
le assumption that the goods in question are completely indivisible. T
his assumption forces persons interested in having a given public good
either to finance it or do without it entirely; they do not have the
option of financing smaller quantities or poorer qualities of the good
.
