This paper considers the problem of bargaining between benevolent juri
sdictions about local public goods and head taxes. It is shown that de
legation to benevolent jurisdictions will, in general, induce distorti
ons away from efficiency, where efficiency means an efficient provisio
n of local public goods and an efficient distribution of consumers. Th
is distortion is caused by (1) the divergence between social and juris
dictional objectives, and (2) the impossibility for jurisdictions to r
ealize side payments without modifying either the provision of local p
ublic goods or the distribution of consumers.
