In the United Stares, the two principal modes of producing local gover
nment services are in-house provision by government employees and cont
racting out to private suppliers, also known as privatization. We exam
ine empirically how U.S. counties choose the mode of providing service
s. The evidence indicates that state clean-government laws and state l
aws restricting county spending encourage privatization, whereas stron
g public unions discourage it, This points to the important roles play
ed by political patronage and taxpayer resistance to government spendi
ng in the privatization decision.
