Perfect Bradford multipliers : a definition and empirical investigation

Abstract

This study analyzed two literatures for Bradford multipliers calculated b the methods o f Egghe (forthcoming) and Goffman and Warren (1969). Bradford partitionings were evaluated with Pratt's (1977) index of class concentration. Perfect Bradford partitions had a Pratt index of zero. Bradford multipliers associated with these partitions were defined as perfect Bradford multipliers. A search for partitions with a Pratt index of zero revealed that both literatures have many perfect multipliers. An implication o f these results i s that the Bradford multiplier can take a range of values. It was observed t h a t there i s usually one perfect Bradford multiplier that leaves the smallest nunber o f remainder journals out of the partitioning . The perfect Bradford multiplier that leaves the smallest remainder i s the minimun perfect Bradford multiplier.
