A rain barrel is a container that captures and stores rainwater for landscape and garden use during dry periods. Rain barrels provide an external benefit to the community through water conservation.If the government offers a per unit subsidy on rain barrels equal to the per-unit externality, then
the after-subsidy equilibrium quantity of rain barrels will equal the socially optimal quantity of rain barrels.
