Curvilinearity in the diversification–performance linkage: an examination of over three decades of research

While an extensive literature examines the diversification‐performance relationship, little agreement exists concerning the nature of this relationship. Both theoretical and empirical disagreements abound. This study synthesizes findings from three decades of research to address major theoretical issues that remain open to debate. We derive three competing models from the literature and empirically assess these using meta‐analytic data drawn from 55 previously published studies. The results of our tests indicate that moderate levels of diversification yield higher levels of performance than either limited or extensive diversification. Thus, we provide support for the curvilinear model; that is, performance increases as firms shift from single‐business strategies to related diversification, but performance decreases as firms change from related diversification to unrelated diversification. The results also indicate major effects from variation in diversification and performance operationalizations. Copyright © 2000 John Wiley & Sons, Ltd.     

Corporate diversification and the value of individual firms: A Bayesian approach

Research summary: Prior theory suggests that the performance effects of a firm's diversification strategy depend on a firm's individual resources and capabilities and the setting within which it is operating. However, prior tests of this theory have examined the average diversification‐performance relationship across all firms, instead of estimating the diversification‐performance relationship at the individual firm level. Efforts to estimate this average relationship are inconsistent with a central assumption of much of strategic management theory—that firms maximize value by choosing strategies that exploit their heterogeneous resources and individual situation. By adopting an approach that allows an evaluation of the diversification‐performance relationship for individual firms, this article shows that firms, both focused and diversified, tend to choose that diversification strategy—focus, related diversification, or unrelated diversification—that maximizes value. Managerial summary: Instead of a universal diversification discount or premium, this article shows that the effect of diversification on performance is heterogeneously distributed across firms and that firms tend to be rational in their diversification decisions.

Technological diversity,related diversification,and firm performance

Previous findings that related diversification creates value have been called into question over concerns about methodology and measures. Reviewing existing theory to consider how a firm's knowledge base interacts with its product market activity, I address several of these concerns by creating a measure of technological diversity based on citation‐weighted patents. The measure indicates a firm's opportunity for corporate diversification based on economies of scope in valuable knowledge assets, is defined for both single‐ and multibusiness firms, and is not correlated with more fundamental aspects of diversification, such as the number of businesses in the corporate portfolio. Evidence from a large sample of firms shows the positive relationship between diversification based on technological diversity and market‐based measures of performance, controlling for R&D intensity and capital intensity as further indicators of the type of assets underlying diversification. Results hold when controlling for the endogeneity of diversification and performance in a cross‐sectional sample or when controlling for unobserved factors using panel data.

In Search of Innovation and Customer‐related Performance Superiority: The Role of Market Orientation,Marketing Capability,and Innovation Capability Interactions

Understanding the mechanisms through which firms realize the value of their market‐based knowledge resources such as market orientation is a central interest of innovation scholars and practitioners. The current study contends that realizing the performance impact of market orientation depends on know‐how deployment processes and their complementarities in functional areas such as marketing and innovation that co‐align with market orientation. More specifically, this study addresses two research questions: (1) to what extent can market orientation be transformed into customer‐ and innovation‐related performance outcomes via marketing and innovation capabilities; and (2) does the complementarity between marketing capability and innovation capability enhance customer‐ and innovation‐related performance outcomes? Drawing upon the resource‐based view and capability theory of the firm, a model is developed that integrates market orientation, marketing capability, innovation capability, and customer‐ and innovation‐related performance. The validity of the model is tested based on a sample of 163 manufacturing and services firms. In answer to the first research question, the findings show that market orientation significantly contributes to customer‐ and innovation‐related performance outcomes via marketing and innovation capabilities. This finding is important in that market‐based knowledge resources should be configured with the deployment of marketing and innovation capabilities to ensure better performance. In answer to the second research question, the findings indicate that market orientation works through the complementarity between marketing and innovation capabilities to influence customer‐related performance but not innovation‐related performance. Managers are advised to have a balanced approach to managing the deployment of capabilities. If they seek to achieve superiority in customer‐related performance, marketing capability, innovation capability, and their complementarity are essential for attracting, satisfying, building relationships with, and retaining customers. On the other hand, this complementarity would be considerably less important if firms placed greater emphasis on achieving superiority in innovation‐related performance. In contrast to many existing studies, this study is the first to model the roles of both innovation capability and marketing capability in mediating the relationship between market orientation and specific performance outcomes (i.e., innovation‐ and customer‐related outcomes).     

Demand‐side strategy,relational advantage,and partner‐driven corporate scope: The case for client‐led diversification

Research Summary: We advance research on corporate diversification by joining insights from the demand‐side and relational views in strategy to offer a novel theory of client‐led diversification. We propose that client‐led diversification results from a combination of the customer‐driven opportunities emphasized in the demand‐side view and the creation of added value through relational assets that is a central tenet of the relational view. Furthermore, we hypothesize that suppliers’ client‐specific knowledge, clients’ relational commitment to suppliers, and growth opportunities in clients’ markets (relative to the suppliers’ own markets) will magnify the client‐led diversification effect. We test our hypotheses using a longitudinal dataset on patent law firms and their diversification into new domains of patent prosecution work for their corporate clients. Managerial Summary: Explanations of why firms diversify into new lines of business have largely concerned the redeployment of underutilized resources, with little regard to opportunities or influences stemming from firms’ existing customers. In our article, we show how the changing scope of business needs from a knowledge‐based supplier firm's set of existing clients is a central driver of supplier‐firm diversification, and this is especially the case when the level of relational assets shared between a supplier and its clients is higher. In a competitive landscape where suppliers compete intensively for the business of clients, our results show how managers can increase the likelihood of capturing additional business from its existing exchange relationships rather than bearing the risks of seeking new exchange relationships.     

Prior performance characteristics of related and unrelated acquirers

In the diversification literature, studies, particularly those using accounting‐based performance measures, have found that related diversifiers are more profitable and that related diversifiers are in more profitable industries than unrelated diversifiers. Due to the very nature of these studies based on cross‐sectional data, however, the causal relationship between diversification strategy and performance was not clear. This paper focuses on a single event of a large acquisition, which enables us to better identify the sequential relationships between prior firm profitability, prior industry profitability, and subsequent acquisition strategies. By doing so, this paper makes clearer the causal relationships between firm profitability, industry profitability, and acquisition strategies. Copyright © 2003 John Wiley & Sons, Ltd.     

Within‐business diversification in technology‐intensive industries

This study extends diversification research to a new level of analysis, examining how within‐business diversification, which occurs when firms extend existing product lines or expand into new ones, affects organizational survival. While prior research suggests that corporate‐level diversification accounts for relatively little variation in performance, within‐business diversification matters a great deal, by influencing which start‐ups survive and which firms better cope with rapid environmental change. Specifically, we find that the relationship between within‐business diversity and survival is contingent on the amount of environmental change wrought by a firm's competitors as they simultaneously diversify their own product portfolios and innovate technologically. Analysis of the population of U.S. personal computer manufacturers from the industry's founding in 1975 through 1994 supports our premise: Regardless of its effects across businesses, diversification matters a great deal within them.

Geographic scope,product diversification,and the corporate performance of Japanese firms

The study extends research on the geographic scope, product diversification, and performance relationship by exploring both the antecedents and consequences of geographic scope. In so doing, it addresses a fundamental criticism of the geographic scope–performance relationship; namely, that the observed positive relationship between geographic scope and performance is spurious because it is the possession of proprietary assets that is the foundation of superior performance, not expansion into international markets per se. We tested the research model with data on the corporate performance of 399 Japanese manufacturing firms. In the partial least squares analyses used to examine the study’s six main hypotheses, we demonstrate that geographic scope was positively associated with firm profitability, even when the competing effect of proprietary assets on firm performance was considered. Further, we find that performance was not related to the extent of product diversification, although investment levels in rent‐generating, proprietary assets were related to the extent of product diversification.

Diversification in context: a cross‐national and cross‐temporal extension

This research note examines the stability of diversification performance relationships in three countries (France, Germany and the United Kingdom), for two time periods (1982–84 and 1992–94). The aggregate findings, taking the three countries and two time periods together, support a general model favoring related‐constrained diversification. However, disaggregated analyses show sharp variations in different countries and time periods. The note concludes that although broad performance relationships can be found, these can be expressed very differently in particular contexts. We consider implications for further research.

Strategic promotion tournaments and worker performance

In this analysis I study promotion schemes as human resource management strategies by which the firm can realize strategic goals by motivating workers to higher levels of effort and performance. Using information on promotions, wages, and performance for professional workers in a cross‐section of establishments in four metropolitan areas of the United States, I investigate empirically the proposition that firms strategically organize promotion tournaments to motivate workers to higher levels of performance. I present evidence suggesting that relative performance of workers determines promotions, supporting the notion of internal promotion competitions in which internal hiring policies and fixed job slots combine to create competitions among workers of a given rank in a firm. I then estimate a structural model of promotion tournaments that simultaneously accounts for worker and firm behavior and how the interaction of these behaviors gives rise to promotions. The results are consistent with the prediction of tournament theory that workers are motivated by larger spreads. Copyright © 2006 John Wiley & Sons, Ltd.     

Diversification and Economic Performance: An Empirical Assessment of Chinese Firms

Integrating the impact of both resource and institutional factors and taking into consideration potential agency problems, this study proposes to investigate the joint effect of both related and unrelated diversification strategies on firm performance in an emerging economy setting and to assess empirically the hypothesized relationship using Chinese firms. The empirical results support the basic contention that both resource building and utilization through concentration and related diversification and institutional environmental management through unrelated diversification are important for firm performance in emerging economies but they must be considered together. This paper concludes with a discussion of its contributions, practical implications, and directions for future research.     

How do interdependencies among human‐capital deployment,development, and diversification strategies affect firms' financial performance?

Using key insights from the resource‐based view of the firm, we develop and test a theory of how firms can successfully deploy and develop their strategic human assets while managing the trade‐offs in their service and geographical diversification strategies. In a sample of large law firms we find that, even though firms profit from expert human‐capital leveraging strategy and service and geographical diversification strategies individually, pursuing these strategies simultaneously at high levels produces negative interaction effects on firm profitability. In addition, the internally developed, firm‐specific associate human capital strategically fits better with high levels of expert human‐capital leveraging. While lateral hiring helps firms build new knowledge bases and take advantage of growth opportunities, pursuing high levels of both expert human‐capital leveraging and lateral hiring of associates results in lower profitability. To fully capture the economic benefits from strategies of diversification, human‐capital leveraging and lateral hiring, firms should understand and manage the complex interdependencies among multiple levels of strategy.

The dynamics of product innovation and firm competences

This study examines how product innovation contributes to the renewal of the firm through its dynamic and reciprocal relation with the firm's competences. Field research in five high‐tech firms of varying age, size, and level of diversification is combined with analysis of existing theory to develop the findings of the study. Based on the notion that new products are created by linking competences relating to technologies and customers, a typology is derived that classifies new product projects based on whether a new product can draw on existing competences, or whether it requires competences the firm does not yet have. Following organizational learning theory, these options are conceptualized as exploitation and exploration. These organizational learning concepts are used to gain a dynamic and path‐dependent view of product innovation and firm development, and to reveal the unique nature and challenges of different types of product innovation.

MNC strategies,exogenous shocks,and performance outcomes

This paper examines the effect of international diversification on multinational corporation (MNC) performance in the face of exogenous shocks in the global business environment, and the extent to which MNCs' internationalization aids or impedes post‐shock performance. We use the September 11, 2001 attacks as a research setting to investigate the relationship between international diversification and MNC performance after a sudden change in the environment. The empirical tests on a sample of 191 U.S. MNCs and a matched sample of non‐U.S. MNCs indicate that the level of pre‐September 11 international diversification is negatively correlated with immediate cumulative abnormal returns to shares, but positively correlated with longer‐term performance.

Agency theory and the influence of equity ownership structure on corporate diversification strategies

We articulate the agency theory view of managerial decision making and its implications for corporate diversification strategies. From agency theory, we generate testable predictions for the relation between equity ownership structure and diversification strategies and review the existing evidence on this relation. On balance, the evidence strongly supports the view that ownership structure influences corporate strategy. Copyright © 1999 John Wiley & Sons, Ltd.     

Structure and process of diversification,compensation strategy,and firm performance

This study tests six hypotheses on the extent to which a match between compensation and diversification strategies affects firm performance. Using both archival and survey data, results generally support the notion that a firm's compensation strategies make a greater contribution to firm performance if these are attuned to extent and process of corporate diversification. The paper concludes with a set of recommendations for future research on compensation-diversification strategy relations and their interactive effect on firm performance.     

Variations in ownership behavior and propensity to diversify: a study of the Indian corporate context

The relationship between ownership and diversification has been the focus of renewed debate between financial economists and strategic management scholars. While financial economists hold that manager‐controlled firms tend to reflect higher levels of diversification, strategy researchers argue that ownership and diversification are not systematically related. In throwing light on this debate, this study uses a fine‐grained definition of ownership groups to explore how the different objectives and monitoring predispositions of distinct ownership groups might influence diversification strategy. The empirical examination is set in India to offer a striking contrast from the predominantly U.S.‐based studies that have shaped the ongoing debate. Findings show that diverse ownership groups adopt different postures in monitoring and/or influencing organizational diversification. While some ownership groups are closely associated with focused strategies, and some encourage diversification, others are quite indifferent. These results suggest that the context‐specific variation among ownership groups is germane to our understanding of diversification strategy. Copyright © 2002 John Wiley & Sons, Ltd.     

The industry context of strategy,structure and performance: The U.K. brewing industry

This paper is concerned with identifying influences on the competitive performance of companies involved in the U.K. brewing industry. It seeks to identify key strategic characteristics, relate these to company performance and move towards an explanation of the influences that emerge as influencing competitive standing. It argues that diversification strategies must be studied as an aspect of industry structure, and shows that more focused, limited diversification and regional brewing strategies may be preferable in the context of the U.K. brewing industry. The research findings conflict with those of many previous studies which research the diversification strategies of primarily large firms (both in the U.S. and the U.K.) drawn from across-industry samples (e.g. the Fortune 500 firms) and which identify superior performance for related diversification strategies. The study therefore provides support for the hypothesis that there is an optimum level of diversification within an industry which balances economies of scope and diseconomies of organizational scale. In the context of the U.K. brewing industry the traditional single or dominant business brewers seem to have found the strategy which matches firms effectively with the important characteristics of industry structure.     

基于PSM-DID模型的政策对试点企业经营绩效的影响评价研究——以"供应链创新与应用试点"政策为例

近年来,我国政府积极推进供应链领域政策的制定与发布,如何更好地评估既有政策带来的绩效成为政府进一步完善供应链相关政策的关键。本文选取商务部“供应链创新与应用试点”政策(商建函[2018]142号)作为研究对象,并构建双重差分倾向得分匹配(PSM-DID)模型,将试点企业经营绩效中的盈利能力指标ROA作为被解释变量,利用Stata15.0对2015~2019年5年间覆盖3494家样本企业的面板数据,共15278个样本进行处理计算,以此对该政策实施对试点企业经营绩效的影响效果进行评价。结果表明:2018年开始实施的供应链创新与应用试点政策,对试点企业的经营绩效ROA有着显著的正向促进作用。此外,企业规模、企业的资产负债率、托宾Q值和企业固定资产投资比率都对ROA有显著影响。其中企业规模和托宾Q值对ROA有正向影响,资产负债率和固定资产投资比率对ROA有负向影响。     

Contestability and creative destruction: Two approaches to monopoly

The theory of contestability ’attempts to base a model of economic efficiency on oligopolistic markets, thereby justifying adoption of laissez-faire policies in the absence of atomistic competition. The analysis is similar to Schumpeter’s condemnation of government intervention in the theory of creative destruction: both theories claim that superior economic performance is associated with concentrated rather than competitive market structures. Yet in many respects the contestability analysis is less convincing than Schumpeter’s. Whereas Schumpeter admitted the existence of short rum profits and restrictive strategies, arguing that these inefficiencies, are outweighed in the long run, the theory of contestable markets is based on short run efficiency and cannot accommodate evidence of excess profits nor many of the existing models of oligopolistic strategies, including collusion and predatory pricing. Furthermore, the theory lacks a logical explanation of investment, by entrants and convincing empirical support for its claim that concentrated markets maximize consumer welfare.
