This article assesses the extent to which managed competition could be
successful in rural areas. Using 1990 Medicare hospital patient origi
n data, over 8 million rural residents were found to live in areas pot
entially without provider choice. Almost all of these areas were serve
d by providers who compete for other segments of their market. Restric
ting use of out-of-State providers would severely limit opportunities
for choice. These findings suggest that most residents of rural States
would receive cost benefits from a managed competition system if purc
hasing alliances are carefully defined, but consideration should be gi
ven to boundary issues when forming alliances.
