The relationship between product and international diversification: The role of experience

We establish prior diversification experience as a key determinant of the relationship between growth of product and international diversification. Prior diversification experience allows firms to overcome short‐run constraints on simultaneous diversification growth imposed by the difficulty to transfer tacit knowledge, ambiguous competencies, and limited absorptive capacity. Studying U.S. and European firms, we find a positive relationship between growth in product and international scope for firms with high and a negative one for those with little prior diversification experience. Further, we find that product diversification experience has greater impact than international diversification experience. Copyright © 2014 John Wiley & Sons, Ltd.     

Foreign‐based competition and corporate diversification strategy

Since the mid‐1980s U.S. domestic firms have faced significant increases in foreign‐based (i.e., import) competition as reductions in barriers to international commerce have resulted in markets and industries becoming increasingly global. Despite the growing and widespread importance of foreign‐based competition, the influence that such competition may exert on corporate diversification strategy is a question largely overlooked in the strategic management literature. This paper examines the impact of foreign‐based competition in a firm's core business on both the level and nature of a firm's diversification strategy at the corporate level in a panel dataset of U.S. firms over the period 1985–94. Our findings provide the first evidence that increased foreign‐based competition is indeed a statistically significant factor explaining both the reduced business‐level diversity and the increased strategic focus of U.S. firms that has been widely perceived over the past two decades.

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.     

Firm success, national status, and product line diversification: An empirical examination

This study investigates the motives for product line diversification by multiproduct firms in the U.S. brewing industry. Historical data are used to examine the evolution of pioneer products, and a Poisson regression model is estimated to analyze the effects of market and firm characteristics on the motives for product line diversification. The results indicate that unsuccessful firms and large national firms are generally more likely to expand their product lines.     

Opportunity costs,industry dynamics,and corporate diversification: Evidence from the cardiovascular medical device industry, 1976–2004

This paper examines how demand conditions across alternative markets impact diversification decisions and firm performance by influencing the opportunity costs of deploying non‐scale free capabilities. Using data within the cardiovascular medical device industry, this study shows that: (1) firms with a larger stock of pre‐entry innovation experience are more likely to diversify; (2) firms in a current market with greater relative demand maturity are more likely to diversify; (3) diversification is associated with a performance decrease in the current market; and (4) diversification is associated with a performance increase at the corporate level. These findings shed new light on the self‐selection process of corporate scope, the conceptualization of firm capabilities, and the connection between industry dynamics and resource deployment.

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.

Inter‐temporal economies of scope,organizational modularity,and the dynamics of diversification

The question of whether corporations add value beyond that created by individual businesses has engendered much debate in recent years. Some of this debate has focused on the pros and cons of related vs. unrelated diversification. A standard explanation of the benefits of related diversification has to do with the ability to obtain intra‐temporal economies of scope from contemporaneous sharing of resources by related businesses within the firm. In contrast, this paper deals with inter‐temporal economies of scope that firms achieve by redeploying resources and capabilities between related businesses over time, as firms exit some markets while entering others. The transfer of resources due to market exit distinguishes our treatment of inter‐temporal economies of scope from standard intra‐temporal economies of scope. In addition, these inter‐temporal economies can benefit from a decentralized and modular organizational structure. This ability to obtain inter‐temporal economies of scope via organizational modularity and recombination suggests that corporations do not necessarily need a high degree of coordination between business units in order to benefit from a strategy of related diversification.

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.     

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.

Multinationals' diversification and the risk-return trade-off

This paper advances a theoretical rationale to explain Bowman's paradox (1980) that firms with high returns can have low risk. Here we draw on the rich body of international management research and argue that global market diversification, which provides firms with three distinct options and opportunities over domestic firms, can explain the high return-low risk profile. We also argue that no strong theoretical rationale exists in support of either related or unrelated product diversification generating such a favorable risk-return profile. By integrating both the product and the global market dimension of diversification into our analyses and by controlling for the industry effect, this paper sheds new light on the relationship between corporate diversification and the risk-return tradeoff. The results of this research, which are based on the diversification experiences of 125 multinationals, reveal the strikingly important, though so far overlooked, role that global market diversification plays in the joint management of corporate risk and return. Global market diversification here reflects both the multiplicity of international market areas in which a firm operates and the distribution pattern of a firm's industries across these multiple areas.     

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.

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.

The performance implications of intra‐ and inter‐regional geographic diversification

Engaging the debate regarding the appropriate level of geographic diversification for multinational enterprises (MNEs), we examine a critical, yet unresolved, question: How is performance impacted by the MNE's level of intra‐ and inter‐regional diversification versus the total level of geographic diversification? Using data from 123 U.S.‐based MNEs over a seven‐year period and leveraging both sales‐based and subsidiary‐based measures for diversification, we find that performance increases at an increasingly higher rate as firms concentrate more heavily on intra‐regional diversification. Regarding inter‐regional diversification and total geographic diversification, we find inverted‐U relationships to exist between firm performance and the level of geographic diversification. Different from recent research on multinationality, our robustness checks indicate no evidence of a sigmoidal relationship between the degree of regional diversification and performance.

The relationship between corporate diversification and corporate social performance

Does diversification affect firm response to stakeholder demands and social issues? Despite extensive interest in corporate diversification in the strategy literature, the relationship between diversification and corporate social performance (CSP) remains largely unexplored. In this study, I propose that the level of diversification will be positively related to the CSP of firms. However, when diversified firms have a strong focus on short‐term profit, it may discourage firm response to stakeholder demands and investment in social issues, thereby negatively moderating the positive relationship between the level of diversification and CSP. Empirical testing on a sample of U.S. firms generally supports my predictions. Copyright © 2012 John Wiley & Sons, Ltd.     

Global equity offerings,corporate valuation,and subsequent international diversification

Researchers have long wondered why U.S. firms offer their equity in multiple global capital markets even though they have access to a deep domestic capital market. Based on a propensity score‐matching sample of IPOs for U.S. firms from 1990 to 2003, this paper offers some potential answers. We find strong evidence that issuers who choose global equity offerings experience higher valuations at the IPO stage, as measured by Tobin's q. Our evidence also shows that global equity offerings serve as a deliberate strategic tool to increase issuers' international visibility and their propensity to diversify operationally to international markets.

Firms' technological resources and the performance effects of diversification: a longitudinal study

While agency theory claims managerial self‐interest creates a diversification discount, strategic theory explains that firms with certain kinds of resources should diversify. Longitudinal data on 227 firms that diversify between 1980 and 1992 reveal that the sample firms invest less in R&D and have greater breadth of technology (based on patent citations) than their industry peers prior to the diversification event. Also, acquiring firms may appear to have lower performance because of accounting conventions and because firms that use internal growth rather than acquisition pursue less extensive diversification. These findings help explain how diversification and financial performance are endogenous. Copyright © 2004 John Wiley & Sons, Ltd.     

Core business regulation and dual diversification patterns in the telecommunications industry

A firm is confronted with the separate decisions of product and international diversification. It is suggested that these postures are linked to external contingencies in firms who face core business regulation. A technique is developed to explain dual diversification patterns using evidence obtained from the new industry comprised of the Regional Bell Operating Companies (RBOCs).     

Product and international diversification among Japanese multinational firms

This paper examines the relationship of performance with product and international diversification on Japanese multinational firms from 1977 to 1993. We show the relationships between diversification and performance change over time through the use of multiple time periods and accounting for keiretsu membership. Results show that while diversity strategies vary between keiretsu and non‐keiretsu firms, performance is not much different. Across time periods, performance varies considerably, but strategies are less variable. Product diversity has weak effects on firm performance only in one time period, while international diversification has negative profitability and positive growth consequences in in some periods. These results suggest first that diversification strategies and their effects on performance vary across time periods and generally produce some unexpected findings. We do not find strong interactive diversity effects. Copyright © 2000 John Wiley & Sons, Ltd.     

Industry Structure,Segmentation, and Quality Competition in the U.S. Hotel Industry*

We examine how quality competition affects the relationship between market size and industry structure at the product level using evidence from the U.S. hotel industry. Starting in the early 1980s, quality competition for business travelers became more based on variable and less on fixed costs, and became less scale intensive. Since then, market size increases have been met by more, but smaller, hotels in business travel destinations but continued to be met by larger hotels in personal travel destinations. Our results illustrate how the way consumers benefit from increases in market size depends on how firms compete.     

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.
