New Institutional Economics' contribution to strategic groups analysis

Rather than consider the two broad strands of strategic group research-performance-based and behavior-based studies-as competing approaches, we argue that they relate to complementary levels of analysis. We present a four-level framework for analyzing structures within industries drawn from New Institutional Economics (NIE) which covers different approaches to strategic group formation from institutional isomorphism and embeddedness through to the firm-level effects of certain resource deployments. We apply an institutional approach to a case study of the Australian banking industry and supplement this with a quantitative approach based around key strategic variables. This analysis suggests that distinct groups have emerged due to the institutional environment and the different regulatory environments experienced by various banks in the industry.
