Generic knowledge strategies in the U.S. pharmaceutical industry

Abstract

The purpose of this study is to identify groups of firms with similar generic knowledge strategies, determine how these strategies change over time, and compare profit margins of the groups. Knowledge strategies of 21 U.S. pharmaceutical firms are analyzed from 1977 to 1991. Cluster analysis is used to group firms over different time periods based on: (a) balance between internal and external learning, (b) preference for radical or incremental learning, (c) learning speed, and (d) breadth of knowledge base. Our findings indicate that there are four generic knowledge strategy groups: ‘Explorers’, ‘Exploiters’, ‘Loners’, and ‘Innovators’. Most firms remain in the same knowledge group over time. The firms in the ‘Innovator’ and ‘Explorer’ groups tend to be more profitable than the firms in the ‘Exploiter’ and ‘Loner’ groups.
