Hybrid strategic groups

The notion of strategic groups has recently emerged as a critical perspective for uncovering firms' strategic postures/recipes and competitive market structures. Firms within strategic groups generally adopt similar strategic recipes and compete more intensely than firms across strategic groups. Building on recent research, the authors develop the concept of hybrid strategic groups, which blend the strategic recipes of more than one group, in contrast to existing conceptualizations of strategic groups, where either firms tightly follow the recipes of a strategic group (i.e., core firms) or firms loosely follow the recipes of a strategic group (i.e., secondary firms). Thus, competition among firms depends not only on the strategic group but also on the overlap of that strategic group with other strategic groups. The authors devise a combinatorial optimization-based classification procedure utilizing a bilinear model that accommodates multiple variable batteries that can estimate hybrid strategic groups. The proposed methodology is illustrated by using archival data on public banks. For this illustration, the hybrid strategic group solution outperforms ordinary cluster analyses and offers critical insights into the nature of competition among firms.

Asymmetric rivalry between strategic groups: response,speed of response and ex ante vs. ex post competitive interaction in the spanish bank deposit market

The objective of this study is to examine asymmetric rivalry between strategic groups in a given industry. Two research hypotheses argue for the existence of asymmetric rivalry in the sense that strategic groups of small companies have a greater degree of response but a slower speed of response to the actions of strategic groups of large companies, than vice versa. To test this, we use an ex post approach that examines the news releases published on the strategic actions and reactions of firms. A third hypothesis compares ex ante competitive expectations with ex post asymmetric rivalry between strategic groups. To test this, we compare ex post news on actions/reactions with an ex ante approach that estimates conjectural variations. The empirical application carried out on bank deposits in the Spanish market defines strategic groups in terms of size due to the historical and institutional conditions of the industry (deregulatory change). The results obtained show that rivalry patterns between strategic groups in terms of company size can be predicted as asymmetric in the sense that smaller bank strategic groups have a greater degree of response (Stackelberg ‘leader–follower’ competitive interaction), and a slower speed of response to the actions of larger bank strategic groups than is found the other way around. Moreover, ex ante expectations of aggressiveness on the part of larger strategic groups characterize greater ex post reactions from the smaller‐size strategic groups. Therefore, the size distribution of strategic groups is valuable to research on complex industries with deregulation changes. Copyright © 2005 John Wiley & Sons, Ltd.     

An evolutionary perspective on strategic group emergence: a genetic algorithm‐based model

We develop a simulation model to examine conditions under which strategic groups emerge and their performance difference persists. In our model, mobility barriers, strategic interactions among high performers, dynamic capabilities (the mechanisms that allow winners to continue to survive), and boundary of rivalry are put together to derive their joint implications for the evolution of strategic groups. Not surprisingly, our model behavior shows that mobility barriers and strategic interactions play an important role in sustaining intergroup performance difference. However, the extremely high level of mobility barriers is shown to impede the emergence of strategic groups. We also find that dynamic capabilities and boundary of rivalry are as essential as mobility barriers in understanding the emergence and stability of strategic groups. When dynamic capabilities are absent or when rivalry is extended over firms with dissimilar strategies, strategic groups are less likely to exist. These findings can serve as a guideline for empirical research to probe why strategic groups exist sometimes and why they do not at other times. Copyright © 2002 John Wiley & Sons, Ltd.     

Strategic groups as reference groups: Theory,modeling and empirical examination of industry and competitive strategy

Previous studies on strategic groups have mainly focused on their static characteristics in order to test the theory of strategic groups and intraindustry performance differences (Porter, 1979; Cool and Schendel, 1988; Fiegenbaum and Thomas, 1990). In contrast, this study takes a longitudinal, dynamic perspective and describes the forces driving strategic group membership and structural evolution. It proposes that a strategic group acts as a reference point for group members in formulating competitive strategy. A partial adjustment model of strategic mobility is then developed which incorporates the idea of a strategic group as a reference group. It models strategic change in an industry both within and across strategic groups. The model is tested in the context of an in-depth industry analysis of the more significant firms in the insurance industry over the 1970-84 time period. The results suggest that strategic groups act as reference points for firm strategies and that predictions of future firm strategies and industry/group structures may also be successfully derived.     

Dynamic strategic groups: deriving spatial evolutionary paths

Recent theoretical developments in the domain of strategic groups, specifically those related to cognitive groups and strategic group identity, seem to suggest that strategic group membership is likely to be relatively stable over time and that firms in a strategic group co‐evolve. Yet appropriate data analytic approaches that use information about firms over time to identify stable strategic groups and their evolutionary paths have been lacking. To overcome such limitations, this research proposes a new clusterwise bilinear multidimensional scaling model that can simultaneously identify (1) the number of strategic groups, (2) the dimensions on which the strategic groups are based, and (3) the evolution of the strategy of these groups over time. Our discussion encompasses various alternative model specifications, together with model selection heuristics based on statistical information criteria. An illustration of the proposed methodology using data pertaining to strategic variables for a sample of public banks in the tristate area of New York, Ohio, and Pennsylvania across three time periods (1995, 1999, and 2003) identifies two underlying dimensions with five strategic groups that display very different evolutionary paths over time. Post hoc analysis shows pronounced differences in firm performance across the five derived strategic groups. This article concludes with a discussion of the implications of the findings, as well as potential future research directions. John Wiley & Sons, Ltd. Copyright © 2009 John Wiley & Sons, Ltd.     

Strategic groups,competitive groups and performance within the U.K. pharmaceutical industry: Improving our understanding of the competitive process

Strategic group research originated in the 1970s and a number of notable studies centered on the U.S. pharmaceutical industry. Results were, however, conflicting. This paper explores the nature of strategic groups in the U.K. pharmaceutical industry. The study confirms the presence of between six and eight strategic groups across the period studied, 1998–2002. The study also demonstrates a statistically significant relationship between these strategic groups and performance using three performance measures. The paper then compares strategic groups with competitive groups and concludes that the distinction is important and may explain the contradictory findings in earlier strategic group research.

Do strategic groups differ in reputation?

While most strategic group research has focused on performance implications, we consider the relationship between strategic group membership and reputation. Using strategic group identity and domain consensus concepts, we propose strategic groups have different reputations. We find significant differences exist in reputation across three identified strategic groups of U.S. property/casualty insurers, supporting our contention that reputation is a multilevel concept. Post hoc analyses suggest strategic groups with higher reputation also have higher performance on some critical measures, indicating reputation may be a mobility barrier beneficial to members of certain groups. Practitioner implications include challenges of within‐group differentiation in firm reputation. Copyright © 2000 John Wiley & Sons, Ltd.     

STRATEGIC GROUPS AND RIVALROUS FIRM BEHAVIOR: TOWARDS A RECONCILIATION

This research examines the question of whether rivalry is greater between or within strategic groups by utilizing more direct, dynamic and fine-grained measures of rivalry. Examining the competitive actions of firms in different strategic groups to determine if competitive responses were more likely to occur from firms in the same strategic group, or from firms in different strategic groups, the research found that competitive responses cannot be predicted by strategic group membership. Importantly, however, strategic group membership is a predictor of the manner by which firms compete with one another, or the frequency with which they undertake competitive actions, cut prices, instigate warfare and imitate rivals. © 1997 by John Wiley & Sons, Ltd.     

Strategic groups as subsets of strategic scope groups in the Belgian brewing industry

This research report proposes a distinction between strategic scope groups and strategic groups whereby strategic groups are delineated within strategic scope groups. A strategic scope group (SSG) includes firms within an industry that define their business using a four-dimensional ‘strategic space’ consisting of buyer types, product types, geographical reach and level of vertical integration, in a similar way. Within each SSG there may be several strategic groups (SGs). An SG includes firms within an SSG that deploy their resources in a similar way and that compete in the same way. While all firms within an SSG may compete against each other, firms within the same SG compete against each other in a similar way. Within the brewing industry in Belgium five SSGs could be identified. These SSGs differ statistically significantly on a risk-adjusted return on assets measure. SGs themselves did not differ on this performance measure. One may therefore conclude that mobility barriers between SSGs are higher than they are between SGs. © 1997 by John Wiley & Sons, Ltd.     

Do strategic groups exist? an economic framework for analysis

This paper offers a framework and methodology for resolving the question regarding the existence of strategic groups. We say that a strategic group exists if characteristics of the group affect firm performance independently of firm-level and industry-level effects. We argue that group-level effects are a byproduct of strategic interactions among members, and develop an empirical testing model, based on the ‘New Economics of Industrial Organization,’ to distinguish true group effects from spurious effects. From this model, we derive a series of logically consistent propositions, suggesting that while strategic interactions are critical for a group-level effect on profits, mobility barriers are necessary to preserve both groups and their effects over time. A review of prior empirical studies of strategic groups suggests that the inconclusive nature of prior research has been due more to the lack of a theoretical foundation for empirical analysis than to the nonexistence of groups. To the extent that our methods have been employed, there is limited evidence that a rigorous search for strategic groups may prove fruitful. © 1998 John Wiley & Sons, Ltd.     

Competitive positioning within and across a strategic group structure: the performance of core,secondary, and solitary firms

Drawing from economic and cognitive theories, researchers have argued that firms within an industry tend to cluster together, following similar strategies. Their positioning in strategic groups, in turn, is argued to influence firm actions and firm performance. We extend this research to examine performance implications of competitive positioning not just among but also within groups. We find that performance differences within groups are significantly larger than across groups, suggesting that some firms within groups develop better resource or competitive positions. We also find that secondary firms within a group outperform both core firms within the group and solitary firms, the latter being those not belonging to any multifirm strategic group. This suggests that secondary firms may be able to effectively balance the benefits of strategic distinctiveness with institutional pressures for similarity. We conclude that the primary implication of strategic groups does not relate to the ability of firms to create stable, advantageous market segments through collusion. Instead, strategic groups represent a range of viable strategic positions firms may stake out and use as reference points. Moreover, our results concerning secondary firms indicate that firm positioning within a group structure can have performance implications. Copyright © 2002 John Wiley & Sons, Ltd.     

Strategic groups: Theory,research and taxonomy

This paper discusses the concept of strategic groups, focusing upon the importance of intra-industry strategic groupings in understanding differences across firms within an industry. The problems involved in identifying strategic groups within industries are examined through a comprehensive review of recent studies. It is demonstrated that much of the research has used surrogates for elements of a firm's strategic direction, e.g. vertical integration, product range, R & D expenditure, to suggest bases by which creative and sustainable groups are formed. The authors argue that certain theoretical concepts such as mobility barriers, isolating mechanisms and controllable variablesprovide much firmer bases for identifying strategic groups within industries. Thus, taxonomies for understanding the nature of strategic group formulation can be developed. Implications of the strategic group concept for such strategic issues as the structure-performance linkage, firm mobility, patterns of rivalry, industry evolutionand firm growthare then examined. The paper concludes by indicating fruitful directions for strategic group research in the context of the strategic management field.     

Strategic groups and competitive enactment: a study of dynamic relationships between mental models and performance

This study used computer-assisted content analysis of more than four hundred presidents' letters to shareholders to examine empirical linkages between cognitive strategic groups clustered by themes in the reports and strategic groups clustered by performance. We found these groups converged as predicted by the literature, and that mental models and performance are involved in a recursive process of competitive enactment which contributes to strategic group stability. Our research used inductively derived themes from the letters to structure a mental model widely shared in the pharmaceutical industry, and then employed thematic variations to find stable clusters of companies. These thematic clusters were triangulated with the strategic groups from a published study of the same industry, in the same period, and were shown to converge. Additionally, longitudinal linkages between earlier mental models of strategic goals and later reports of performance were found. The findings of our large-scale empirical study support strategic group theory, demonstrate a novel approach to data mining, and pose questions for future research.

Knowledge structures of prospectors,analyzers, and defenders: content,structure, stability,and performance

The managerial cognition perspective argues that managers operating in complex, dynamic environments develop knowledge structures that help them focus their attention, interpretation, and actions. We explore the content and structure of top managers' strategic knowledge structures by measuring differences in the level of attention they give in annual reports to strategic issues and themes that Miles and Snow used to describe their main strategic types. Twenty-one themes that form seven main factors describing managers' strategic cognition are identified, and these demonstrate reasonable fit with the Miles and Snow model. We show that expert raters can recognize these factors when they read annual reports that contain them. Cluster analysis is then used to identify groups of firms that share similar profiles on these strategic dimensions which are interpreted as examples of cognitive strategic groups. These groups show alignment with Miles and Snow's strategic types, are relatively stable over time, and differ in financial performance. The sample comprises 1,038 listed Australian firms between the years 1992 and 2003. Copyright © 2007 John Wiley & Sons, Ltd.     

Rivalry within strategic groups and consequences for performance: the firm‐size effects

Our study examines how, in a given industry, rivalry functions within strategic groups defined according to the size of their member firms and how this rivalry affects performance. We hypothesize that, owing to several forms of group‐level effects including market power, efficiency, differentiation, and multimarket contact, strategic groups that comprise smaller firms will exhibit both increased rivalry and decreased performance compared with strategic groups that comprise larger firms. We test our hypotheses by estimating the effect of group‐level strategic interactions (i.e., conjectural variations) on firm performance. Ultimately, our analysis of empirical data on loans in the Spanish banking industry demonstrates that increased rivalry and decreased performance indeed characterizes firms belonging to a strategic group that comprises smaller firms.

Convergence across alternative methods for forming strategic groups

We studied the convergence of three different methods for identifying group structure (strategic groups) in a single competitive environment. Using a version of the MTMM matrix, we tested the convergent validity of the concept of strategic groups in a mature, geographically delimited competitive environment. We find significant evidence of convergence between competitive structures identified using archival and perceptual data as well as those identified using archival measures of strategy and direct measures of competitors. There is limited evidence of convergence between competitive structures identified from perceptual and direct measures. Taken as a whole, these results are consistent with the emerging theory of strategic groups. We conclude that strategic groups are a theoretical construct and not a methodological artifact, as is suggested by some authors. © 1997 John Wiley & Sons, Ltd.     

A taxonomy of competitive retailing strategies

An important aspect of any scientific investigation involves classifying the phenomena being studied. This research focused on a taxonomic analysis of the limited domain of competitive retailing strategies employed by U.S. supermarket chains for generic brand grocery products. Using cluster analysis, an empirically derived taxonomy was developed, and the characteristics of firms in each of the four strategic groups were examined. In addition, the performance of particular strategic groups was analysed. Firms in one of the strategic groups (aggressive initiators) consistently indicated higher levels of success.     

GETTING TO KNOW YOU: A THEORY OF STRATEGIC GROUP IDENTITY

This paper develops a theory of strategic group identity that explains how strategic groups emerge in an industry and how they can affect firm behaviors and outcomes. In so doing, it provides a theoretical basis for the existence of strategic groups. We argue that managers cognitively partition their industry environment to reduce uncertainty and to cope with bounded rationality. Social learning theory and social identification theory are used to describe how cognitive groups coalesce into meaningful substructures and how a group-level identity emerges. We describe the ways in which macro level factors condition the development of groups and their identities. We introduce the notion of a strong identity, which characterizes any group sufficiently recognized and attended to by members to affect individual action. Groups with ‘weak identities’ are no more than transient agglomerations of firms and do not exist in any meaningful sense. These ideas are developed into propositions that describe the conditions under which groups with strong identities are likely to emerge. A second set of propositions describes their transformation over time. Identity strength is linked to both positive and negative outcomes in a final set of propositions. We show how strategic groups with strong identities can affect firm performance, resolving a longstanding problem which has plagued strategic groups research and conclude by suggesting some approaches for measurement and future research. © 1997 by John Wiley & Sons, Ltd.     

Sources of Competitive Advantage and Firm Performance: The Case of Sri Lankan Value-Added Tea Producers

Given the greater importance of firm-effects as opposed to industry-effects in explaining firm performance, this study incorporated the resource and strategy-based views of the competitive advantage paradigm in explaining the performance of value-added tea producers in Sri Lanka. The study revealed the existence of three significantly different strategic groups and justified the assertion that there is significant intra-industry heterogeneity. Only one strategic group, which comprised four dominant firms, revealed strong mobility barriers and higher performance differences. However, no performance differences were evident between the other two strategic groups.     

An application of clustering for strategic group analysis

Taxonomies, factor analysis and clustering are discussed as tools to investigate the structure of competitors within an industry (‘strategic groups’). An example using cluster analysis is presented as one means of operationalizing this concept. Careful definition and selection of the dimensions used to identify the boundaries between strategic groups (their mobility barriers) are particularly crucial in the effective application of analytical tools.
