The relationship between portfolio diversification and firm value: The evidence from corporate venture capital activity

Corporate venture capital (CVC) activity exposes firms to new technologies and markets. An important but as yet unexplored question is the relationship of the industry diversification profile of the portfolio of venture companies to corporate value creation. Insights from options and diversification perspectives support our hypothesis that diversification of a corporate investor's portfolio of venture companies is related to corporate wealth creation in a U‐shaped relationship. We also propose that a corporate investor's financial constraints moderate the relationship between the diversification profile of its CVC portfolio and value creation. When we tested our hypotheses using a sample of CVC investments across multiple industries, we found support for them, and these findings may inform the CVC activities of corporate investors.

Skill relatedness and firm diversification

Because of the importance of human capital, a firm's choice of diversification targets will depend on whether these targets offer opportunities for leveraging existing human resources. We propose to quantify the similarity of different industries' human capital or skill requirements, that is, the industries' skill relatedness, by using information on cross‐industry labor flows. Labor flows among industries can be used to identify skill relatedness, because individuals changing jobs will likely remain in industries that value the skills associated with their previous work. Estimates show that firms are far more likely to diversify into industries that have ties to the firms' core activities in terms of our skill‐relatedness measure than into industries without such ties or into industries that are linked by value chain linkages or by classification‐based relatedness.

The effects of CEO equity ownership and firm diversification on risk taking

This research explores the effects of CEO equity ownership and corporate diversification on firms' risk‐taking and risk avoidance behaviors. Hypotheses regarding these effects are tested through econometric analysis of mergers in the U.S. cable television industry. Risk taking and avoidance are measured as horizontal expansion through acquisitions and as the divestiture of assets, respectively, in the face of increasing environmental turbulence.

Within‐industry diversification and firm performance—an S‐shaped hypothesis

This study shows that the interplay between “adjustment costs”, “coordination costs” and within‐industry diversification benefits, results in an S‐shaped relationship between within‐industry diversification and firm performance. At low levels of within‐industry diversification, coordination costs are negligible but “adjustment costs” are higher than the synergy benefits of a limited product scope, hence leading to negative performance outcomes. At moderate levels of within‐industry diversification synergies between related product categories substantially increase and outweigh the rise in adjustment and coordination costs, resulting in positive performance outcomes. Yet, extensive within‐industry diversification gives rise to considerable coordination costs, which, coupled with adjustment costs, outweigh synergy effects and hamper performance. The study further shows that a greater change rate of within‐industry diversification results in negative performance outcomes. Copyright © 2014 John Wiley & Sons, Ltd.     

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.

Product variety and firm survival in the microcomputer software industry

This article provides an analysis of product variety and scope economies in the microcomputer software industry by using detailed firm‐level and product‐level information on firms' bundling of functionalities over application categories and computing platforms. We find that the management of product variety through the way different application categories are integrated in products and the platforms on which these products are offered can be as important as the significance of scope economies at the more aggregated firm level. Specifically, we find that there is little evidence of firm benefits from economies of scope in production, but there is substantial evidence that products benefit from economies of scope in consumption. In addition, we find that firms with products that encapsulate more application categories perform better, and those with products that cover more computing platforms perform worse. Finally, changes in product variety through new product introductions improve firm performance, but extensions to existing products hinder the performance of the firm and the product. We conclude that research in scope economies can benefit from a more detailed model of the evolution of product variety that includes data and analysis at the firm level and at the product level.

Intra‐industry diversification and firm performance

We study how intra‐industry product diversity affects firm performance by analyzing the implications of expanding a firm's product line within its core business. We conjecture that increases in product diversity initially undermine performance because of negative transfer effects but then improve it due to economies of scope. We further theorize that this U‐shaped effect of product diversity becomes more pronounced as the firm increases the intensity of its technology investment, yet is likely to be attenuated by the firm's accumulated experience with intra‐industry diversification. Data on 156 U.S.‐based software firms operating from 1990 to 2001 furnish support for these conjectures. Our study advances emerging research on intra‐industry diversification by underscoring some of its contingent performance effects. Copyright © 2013 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.     

Revisiting the firm,industry, and country effects on profitability under recessionary and expansion periods: A multilevel analysis

Research summary: Despite voluminous past research, the relevance of firm, industry, and country effects on profitability, particularly under adverse contexts, is still unclear. We reconcile institutional theory with the resource‐based view and industrial organization economics to investigate the effects of economic adversity, such as the 2008 global economic crisis. Using a three‐level random coefficient model, we examine 15,008 firms across 10 emerging and 10 developed countries for the 2005–2011 period. We find that firm effects become stronger under adversity, whereas industry effects become weaker, as well as country main and interaction effects, particularly among the emerging economies. These findings confirm our assumptions that the firm's own fate is, to a great extent, self‐determined; a reality that is even more pronounced during periods of extreme economic hardship. Managerial summary: In this research, we examine how generalized economic adversity affects the balance across the firm‐, industry‐, and country‐specific factors determining firm profitability. We specifically examine 15,008 firms from 10 emerging and 10 developed countries during the 2005–2011 period to investigate the effects of the 2008 global economic crisis on firm performance. We find that in such adverse conditions, the role of the industry and the country are reduced and the firm's own resources and capabilities become more pertinent for firm performance. This phenomenon is more pronounced across emerging markets. We conclude that the firm's own fate is, to a great extent, self‐determined, a reality that is markedly more evident during periods of extreme economic hardship.

People and process,suits and innovators: the role of individuals in firm performance

Performance differences between firms are generally attributed to organizational factors rather than to differences among the individuals who make up firms. As a result, little is known about the part that individual firm members play in explaining the variance in performance among firms. This paper employs a multiple membership cross‐classified multilevel model to test the degree to which organizational or individual factors explain firm performance. The analysis also examines whether individual differences among middle managers or innovators best explain firm performance variation. The results indicate that variation among individuals matter far more in organizational performance than is generally assumed. Further, variation among middle managers has a particularly large impact on firm performance, much larger than that of those individuals who are assigned innovative roles.

What determines the scope of the firm over time and around the world? An Asia Pacific perspective

“What determines the scope of the firm?” is a fundamental question in strategy research. We argue that a new generation of diversification research needs to address the extended question: What determines the scope of the firm—both product and geographic—over time and around the world? This article has three goals: (1) to increase awareness among researchers on the necessity to add the much needed but often neglected time and geographic dimensions by introducing a new typology in diversification research, (2) to review how Asia Pacific research, including articles in this Special Issue, has contributed to our global understanding along both dimensions, and (3) to advance an institution-based view on diversification strategies that has largely been propelled by Asia Pacific research.     

Synergy,coordination costs,and diversification choices

Sharing common inputs across business lines can potentially generate synergy that justifies related diversification. The pursuit of such synergy through diversification is, however, fundamentally driven by the indivisibility of inputs between firms. Following Penrose's insight, I argue that to realize this synergy, a firm needs to actively manage the interdependencies between different business lines, which, in turn, increases its coordination costs. The coordination costs may increase faster than synergy and set a limit to related diversification. This is particularly salient when the firm's existing business lines already have complex interdependencies among them. I test these arguments on a dataset of U.S. equipment manufacturers for the period 1993 to 2003. The results show that a firm is more likely to diversify into a new business when its existing business lines can potentially share more inputs with the new business; however, the firm is less likely to diversify into any new business when its existing business lines are complex. Importantly, the firm's likelihood of diversifying into a new business decreases more with the complexity in the firm's existing business lines if they share more inputs with the new business. These results suggest that increasing coordination costs counterbalance the potential synergistic benefits associated with related diversification. Copyright © 2010 John Wiley & Sons, Ltd.     

The effect of within‐industry diversification on firm performance: synergy creation,multi‐market contact and market structuration

This paper examines the effect of diversification upon intra‐industry performance. We propose that intra‐industry diversification promises three sets of benefits, which, separately and in combination, provide firms with a competitive advantage: synergies arising from economies of scope; premiums from mutual forbearance enabled by multi‐market competition; and efficiencies derived from market structuration. The additive and integrative effects of the first two have not been explored. The benefits of market structuration remain untheorized and thus untested. The test of our theoretical model in the Canadian general insurance industry indicates that mutual forbearance provides advantage under specified conditions, that market structuration also provides advantages, but that diversification per se does not.

The effects of leveraged buyouts on corporate growth and diversification in large firms

This study investigates the effects of LBOs on corporate growth and diversification in large U.S. firms which underwent leveraged buyouts during the 1980s. Based on the analysis, this study found that revenue and employee growth are significantly lower in LBO firms than in control firms that remained public. Strategically, we find that LBO firms decreased the size of both their periphery and core businesses more than public control firms and that LBO firms divested a significantly higher volume of periphery and core businesses than control firms. These postbuyout differences between LBO and public firms are consistent with the argument that LBO firms provide managers with incentives to downsize and prune lines of business, resulting in reduction in overall firm size and diversifcation.     

The effects of managerial ownership on international and business diversification: Balancing incentives and risks

Research has examined the effects of managerial share ownership on business diversification, typically from the incentive alignment perspective. Yet, share ownership also shifts risk to managers (the efficient managerial contracting perspective). Furthermore, the effects of managerial ownership on international diversification are unexplored. We examine how managerial ownership influences both international and business diversification in light of the trade‐off between incentive alignment and risk bearing. Based on the differing risk profiles of the two types of diversification, we argue that incentive contracts with higher levels of managerial ownership will be inefficient, i.e., counter to shareholder interests—reducing international diversification and increasing business diversification. Our findings support our arguments for international diversification. We find no significant effect for business diversification after accounting for endogeneity and serial correlation.

Dynamic capabilities as antecedents of the scope of related diversification: the case of small firm accountancy practices

We propose that differences in the scope of related diversification in firms can be accounted for by differences in their dynamic capabilities. In order to test this, we analyze 254 Norwegian small firm accountancy practices' possession of key dynamic capabilities including the heterogeneity of their human capital, their internal development routines, and their alliances with complementary service providers. We also analyze the influence of strategic choice, in terms of the positioning of the practice and its underlying strategic intent. While we observe no clear effects for these two latter factors, we find that dynamic capabilities have a distinct impact on the scope of services. Copyright © 2008 John Wiley & Sons, Ltd.     

Testing alternative theories of the firm: transaction cost,knowledge-based,and measurement explanations for make-or-buy decisions in information services

Firms boundary choices have undergone careful examination in recent years, particularly in information services. While transaction cost economics provides a widely tested explanation for boundary choice, more recent theoretical work advances competing knowledge-based and measurement cost explanations. Similar to transaction cost economics, these theories examine the impact of exchange attributes on the performance of markets and hierarchies as institutions of governance. These theories, however, offer alternative attributes to those suggested by transaction cost economics or offer alternative mechanisms through which similar attributes influence make–buy choices. Traditional empirical specifications of make–buy models are unable to comparatively test among these alternative theories. By developing and testing a model of comparative institutional performance rather than institutional choice, we examine the degree of support for these competing explanations of boundary choice. Hypotheses are tested using data on the governance of nine information services at 152 companies. Our results suggest that a theory of the firm and a theory of boundary choice is likely to be complex, requiring integration of transaction cost, knowledge-based, and measurement reasoning. © 1998 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.

多元化经营与多元化折价--企业多元化研究的新进展

对多元化经营的讨论是传统金融学的一个重要议题。一致的共识是多元化经营会损害企业价值，多元化企业存在着多元化折价；而且大量的实证研究也具体度量了多元化折价程度。而近期对多元化经营的研究却从不同的侧面对上述结论提出了置疑。本文在总结了国外对企业多元化最新研究的基础上，认为对多元化折价的置疑本身仍存在诸多问题，因此，不能仅凭相对少量的研究结论就轻易否认多元化折价的存在。
