The market share‐profitability relationship: An empirical assessment of major assertions and contradictions

While previous research on the relationship between market share (MS) and business profitability (BP) has found a positive relationship, its nature (i.e. direct versus spurious), its context‐specificity, and the validity of MS as a predictor of BP have not been adequately addressed. Employing path analysis, this study examined the nature of this relationship across a taxonomy of homogeneous environments. The major findings were that (1) the association between MS and BP is context‐specific; (2) both direct and spurious relationships exist, and their relative strengths vary across environments; and (3) the validity of MS as a predictor of BP is context‐specific. Further, key firm conduct variables accounting for the spuriousness have been identified. Finally, implications of these findings for managers pursuing market share as a goal are discussed.
