Corporate Diversification,Information Asymmetry and Insider Trading

The literature suggests that corporate diversification destroys firm value. This value destruction is usually considered to be a consequence of managers' pursuing diversification strategies to benefit themselves rather than to increase firm value. This paper provides evidence that casts doubt on this agency theory‐based explanation for corporate diversification. Evidence based on insider trading suggests that managers themselves consider their diversification strategies to be value‐increasing. Specifically, it is documented that corporate insiders (directors) purchase more of their firms' shares in the open market when corporate diversification is high. Moreover, insiders purchase more when the level of diversification discount is high, suggesting that they disagree with outside investors' undervaluation due to diversification. It is also found that the market reaction to insiders' purchases is positively related to corporate diversification. This result suggests that outsiders consider the amount of favourable information contained in insiders' purchases to increase with the extent of corporate diversification.     

Fads and Fashions in Management Practices: Taking Stock and Looking Forward

Established management practices – such as Six Sigma or business process re‐engineering, as well as more recent practices such as agile management processes, HR analytics and beyond budgeting – are viewed by practitioners as the basic tools of their trade. Yet they have been known to wax and wane in popularity, often quite unpredictably, with one technique following the other in wave‐like fashion. The scholarly observation of this phenomenon has given rise to the literature on fads and fashions in management studies, which – building on earlier work in allied disciplines – has sought to explain the transience, persistence, and overall trajectory of management practices. In this paper, we review and integrate the existing literature on management fads and fashions, taking stock of the sizable body of work that has accumulated over the past three decades and which has, to our knowledge, never been reviewed comprehensively before. At the same time, we also note that technological change – with the advent of social media and the ubiquity of Internet connectivity, for example – has radically transformed how practitioners seek, consume, and engage with new practices, as well as the way in which such practices are broadcast and diffuse. In our review, therefore, we try to make this well‐established body of literature current by explicitly discussing how well its central tenets and theoretical arguments have stood the test of time, and propose useful directions for moving forward.     

Non‐financial Shareholder Activism: A Process Model for Influencing Corporate Environmental and Social Performance*

Shareholders have become increasingly active in endeavouring to influence companies’ environmental and social practices. In comparison with the mature field of financially motivated shareholder activism, limited enquiries have been carried out on its non‐financial counterparts. This paper synthesizes the knowledge base through a review of the academic literature, exploring shareholder activism intended to affect corporate environmental and social performance. Theoretical perspectives appropriate to this phenomenon are critically appraised: in particular, insights from social movement theory, Hirschman's theory of exit, voice and loyalty and stakeholder salience theory, as well as the roles of signalling and symbolic management actions. Data from the literature are organized into a process model of non‐financial shareholder influence. Underpinned by the influencing context, this conceptualization centres on three primary shareholder interventions: divestment, dialogue and shareholder proposals. These interventions are enabled through a range of actors and tools: coalitions, non‐governmental organizations, codes and indices, the media and regulators. The interaction between interventions and the enabling actors and tools helps to determine managers’ perceptions of shareholder salience. These perceptions subsequently shape the organizational behaviours that affect companies’ symbolic and substantive environmental and social performance. An agenda to direct future research in this burgeoning field is articulated.     

The changing professional organization: A review of competing archetypes

The aim of this paper is to summarize literature relevant to the professional organization and to present a contemporary analysis of the archetype concept in this field. In order to understand recent and ongoing changes in professional organizations, the paper begins with a review of how the professional archetype evolved from the 1960s to 1990. Then, with examples from contemporary accounting, health care and law organizations, it considers the processes by which an institutionalized archetype can change. Forces for change – such as deregulation, competition, technology and globalization – can challenge the interpretive scheme and eventually delegitimize the existing archetype. At the same time, significant environmental changes can override isomorphic pressures and de‐institutionalize the long‐accepted structures. Thus we herald the emergence a new professional archetype – or perhaps several competing archetypes. Finally, the paper reviews the evolving field of professional organization as a whole, and understands the extant archetypes. A typology of professional organizations is proposed that currently seems to have three clusters of organizations – possibly three competing archetypes – namely, the traditional professional partnership, the specialized ‘Star’ form and the corporate global professional network, or GPN.     

Political Corporate Social Responsibility: Reviewing Theories and Setting New Agendas

There has been rising interest in political corporate social responsibility (political CSR), defined as activities where CSR has an intended or unintended political impact, or where intended or unintended political impacts on CSR exist. Based on a survey and content analysis of 146 peer‐reviewed academic articles from 18 journals over the 14‐year period 2000–2013, this paper systematically reviews the existing applications of general theories (such as legitimacy theory, the resource‐based view and Habermasian political theory) within the political CSR literature. The survey indicates that the political CSR field is dominated by institutional theory and stakeholder theory, but future theory development needs to go beyond these theories in order to address a number of critical gaps. This review specifically points to several avenues for future political CSR research with regard to the individual level of analysis, domain integration and political CSR in multinational enterprises. The paper ends with a call for a new theory‐informed and pluralist research agenda on political CSR to integrate different perspectives and re‐examine the role of the state.     

To Divest or not to Divest: A Meta‐Analysis of the Antecedents of Corporate Divestitures

Corporate divestitures have been identified as important strategic actions with a positive impact on firm performance. Yet, what is still missing in the strategic management literature is an integrative framework that quantitatively synthesizes the relative impact of various antecedents to divestitures, and theoretically reconciles the multitude of theories underlying divestiture research. To fill this gap, the author conducts a meta‐analysis (based on a sample of 35 studies) and develops four broad categories of determinants: corporate governance; firm strategy; performance; and industry environment. Evidence is found that divestitures are driven mainly by prior divestment experience, structural factors (firm size and firm diversification) and weak unit performance. In addition, the relative predictive validity of several theoretical perspectives on divestment decisions is assessed.     

A commonsense approach to portfolio planning

For the diversified firm, business portfolio planning offers a way of determining its individual businesses' roles and developing a synergistic corporate strategy. In practice, however, the common tools of portfolio planning—the growth/share and market attractiveness/business position matrices—present problems in that often neither of the matrices is precisely suitable for a given individual business. This article makes use of modifications of the growth/share and market attractiveness/business position matrices in order to make them more operational. The authors believe that a step-by-step ‘shirt-sleeve’ approach to portfolio planning can make this type of analysis accessible and invaluable to a small diversified firm, as well as providing insights to larger corporations with formal planning departments.     

Risk‐Based Sampling: I Don't Want to Weight in Vain

Recently, there has been considerable interest in developing risk‐based sampling for food safety and animal and plant health for efficient allocation of inspection and surveillance resources. The problem of risk‐based sampling allocation presents a challenge similar to financial portfolio analysis. Markowitz (1952) laid the foundation for modern portfolio theory based on mean‐variance optimization. However, a persistent challenge in implementing portfolio optimization is the problem of estimation error, leading to false “optimal” portfolios and unstable asset weights. In some cases, portfolio diversification based on simple heuristics (e.g., equal allocation) has better out‐of‐sample performance than complex portfolio optimization methods due to estimation uncertainty. Even for portfolios with a modest number of assets, the estimation window required for true optimization may imply an implausibly long stationary period. The implications for risk‐based sampling are illustrated by a simple simulation model of lot inspection for a small, heterogeneous group of producers.     

Are Friendly Acquisitions Too Bad for Shareholders and Managers? Long‐Term Value Creation and Top Management Turnover in Hostile and Friendly Acquirers

The well‐documented failure of the majority of acquisitions to create value is often identified in popular discussion with hostile acquisitions, whereas friendly acquirers seem to get a friendly press. The relative performance of friendly and hostile acquirers therefore warrants a rigorous empirical investigation. Clear evidence of superior value creation in hostile over friendly acquisitions allows us to judge the efficacy of the market for corporate control. In this article we examine the long‐term shareholder wealth performance of four types of acquirers – friendly bidder, hostile bidder, white knight and hostile bidder facing a white knight or another hostile bidder. For a sample of 519 acquisitions of UK target firms during 1983–1995, we estimated the three‐year post‐acquisition gains to acquirer shareholders and found that hostile acquirers deliver significantly higher shareholder value than friendly acquirers. We found that friendly acquirers with high stock‐market ratings destroyed more value than hostile acquirers with a similar rating. Friendly acquirer top managers suffered greater job losses than those of hostile acquirers, perhaps paying the price for their inferior value‐creation performance. Our study provides evidence of the superior value‐creation performance of hostile acquirers and makes the case against takeover regulatory rules that may impede hostile takeovers.     

Accelerating the Innovation Process: A Systematic Review and Realist Synthesis of the Research Literature

There is continued interest among academics, practitioners and policy‐makers in methods to achieve accelerated innovation. Academic studies of this complex phenomenon have succeeded in reaching a high degree of consensus on the antecedents of innovation speed. The aim in this review is to elucidate further the mechanisms underlying management interventions to promote speed. The review adopts a theory‐led, realist synthesis of innovation speed research – the first example of this methodology in management studies. The authors develop a new time‐based framework for categorizing the innovation‐speed literature. The framework has a CIMO logic, and is built by invoking the organizational studies literature on time. The authors contextualize the innovation‐speed literature in relation to the three generic temporal challenges faced by all organizations: reducing temporal uncertainty; resolving temporal conflicts over activities; and allocating resources amid conditions of temporal scarcity. They problematize extant explanations of innovation speed as not taking account of different temporal orientations (temporal dichotomies) within innovation work, and thereby neglecting a potential barrier to achieving accelerated innovation outcomes. They further draw on the literature on time in organizations to suggest new avenues of research, and methodological approaches new to the study of innovation speed. The principal contribution of this review is to offer a new conceptual perspective on the complex empirical research examining how innovation projects may be accelerated from original idea to launch.     

Labour Market Flexibility,Human Resource Management and Corporate Performance

Labour market flexibility is often portrayed as a key to the competitive success of the UK and US economies. We surveyed several hundred firms in the UK, and using the resulting data (on over 200 manufacturing firms) this paper investigates the relationships between firms’ use of flexible work practices, human resource systems and industrial relations on the one hand, and corporate performance on the other hand. The results suggest that ‘low‐road’ practices – short‐term contracts, a lack of employer commitment to job security, low levels of training and low levels of human resource sophistication – are negatively correlated with corporate performance. In contrast, it is found that ‘high‐road’ work practices –‘high commitment’ organizations or ‘transformed’ workplaces – are positively correlated with good corporate performance. It is also found that human resource management practices are more likely to contribute to competitive success where they are introduced as a comprehensive package, or ‘bundle’ of practices. Significant interaction effects between human resource systems, trade unions and flexible work practices add further support to the bundling hypothesis.     

Shades of Grey: Guidelines for Working with the Grey Literature in Systematic Reviews for Management and Organizational Studies

This paper suggests how the ‘grey literature’, the diverse and heterogeneous body of material that is made public outside, and not subject to, traditional academic peer‐review processes, can be used to increase the relevance and impact of management and organization studies (MOS). The authors clarify the possibilities by reviewing 140 systematic reviews published in academic and practitioner outlets to answer the following three questions: (i) Why is grey literature excluded from/included in systematic reviews in MOS? (ii) What types of grey material have been included in systematic reviews since guidelines for practice were first established in this discipline? (iii) How is the grey literature treated currently to advance management and organization scholarship and knowledge? This investigation updates previous guidelines for more inclusive systematic reviews that respond to criticisms of current review practices and the needs of evidence‐based management.     

ISO 9001 and ISO 14001: Towards a Research Agenda on Management System Standards*

Management system standards, also called meta‐standards, have been adopted by an increasing number of organizations across the world. Although these management system standards are based on the same type of management principles and institutional arrangements, the literature remains scattered, with diverse studies focused on specific standards and published in various journals. The main objective of this paper is to analyse the academic research on meta‐standards through an integrative review intended to shed light on the main conclusions and substantial advances made in this area. This integrative review focuses more specifically on the two main meta‐standards which have been adopted by more than 1.3 million organizations worldwide: ISO 14001 and ISO 9001. The paper contributes insights into the main streams of the literature and current knowledge gaps to be addressed in future research on the various issues related to meta‐standards: global governance, diffusion processes, motivations, benefits of adoption and impacts on performance, internalization, integration, consultancy and auditing.     

Managing Risk as a Duality of Harm and Benefit: A Study of Organizational Risk Objects in the Global Insurance Industry

This study examines how organizations construct and manage risk objects as a duality of harm–benefit within their normal operations. It moves beyond the existing focus on accidents, disasters and crisis. We study the risk‐transfer processes of 35 insurers where they navigate the tension of retaining risk in their insurance portfolio to increase the benefit of making profit and transferring risk to reinsurance to reduce the harm of paying claims. We show that organizations’ constructions of risk are underpinned by everyday risk management practices of centralizing, calculating and diversifying. Through variation in these practices, not all organizations seek balance and we in turn uncover the sensemaking processes of abstracting and localizing that enable organizations to prioritize harm or benefit. This contributes to the risk literature by illuminating the co‐constitutive relationship between risk sensemaking processes and everyday risk management practices. Following the complex linkages involved in the construction of risk objects as sources of harm–benefit, our analysis also contributes to the literature on dualities. It shows that while immediate trade‐offs between harm–benefit occur, prioritizing one element of the duality is ultimately a means for attaining the other. Thus, while initial imbalance is evident, prioritization can be an enabling approach to navigating duality.     

Portfolio theory—A planning tool

Portfolio theory is a relatively new development in the area of asset selection and diversification. Nevertheless, many articles, books and dissertations have been written to elaborate on the original concepts to such an extent that portfolio theory is now accepted doctrine in the field of finance.Portfolio theory deals with the rules for the intelligent selection of assets under conditions of risk. In this respect it is similar to planning, part of which consists of examining alternative courses of future action. Most of the research concerning portfolio theory has been directed toward the securities markets. Therefore, some of the terminology is investment oriented. Nevertheless, the concepts developed in portfolio theory can be applied to decisions concerning investments or to decisions that are part of a corporate plan. Think of investing in a security as being analogous to investing in a subsidiary, division, or product line. This article explains the major features of portfolio theory with the hope that corporate decision makers will use portfolio theory as a planning tool.     

The Strategic Management of Innovation: A Systematic Review and Paths for Future Research

Strategic management scholars have long emphasized the importance of innovation for a firm's competitive advantage and performance. However, the current state of knowledge about the strategic management of innovation is characterized by conflicting theoretical predictions, persisting knowledge gaps and theoretical inconsistencies. Adopting a ‘systematic’ approach to reviewing the literature, this paper combines different quantitative methods – co‐word analysis, cluster analysis and frequency analysis – to review 342 articles on the strategic management of innovation published in seven journals from 1992 to 2010. On the basis of these analyses, suggestions are developed for future research which could help to promote future theory development and provide relevant material for policy decisions that managers and executives have to make when they manage innovation.     

Human resources management and corporate governance: Integration perspectives and future directions

The aim of this article is to investigate, through a systematic review of the literature, what has been studied and published in the international academic literature regarding the integration between human resources management (HRM) and corporate governance (CG).We accomplished it answering two research questions: How has evolved the academic publications regarding the integration between HRM and CG? and Under which theoretical perspectives the integration between HRM and CG has been studied? The research covered the publications from 2000 to 2017, and the analysis comprises 79 articles from relevant international journals. The results revealed the predominance of a shareholder theoretical perspective and the apparent legitimation of HRM as an important variable of CG, but with a secondary position, as consultant or processes provider. Besides exploring and exposing the state of the art in this area of knowledge, through a critical analysis of the literature, this study highlights the gaps in the literature and provides suggestions for future studies.     

All the bottles in one basket? Evaluating the effect of intra-industry diversification on risk

This paper develops a framework using Monte Carlo simulation to examine risk/return properties of intra-industry product portfolio composition and diversification. We use product-level data covering all Swedish sales of alcoholic beverages to describe the risk profiles of wholesalers and how they are affected by actual and hypothetical changes to product portfolios. Using a large number of counterfactual portfolios we quantify the diversification benefits of different product portfolio compositions. In this market the most important reductions in variability come from focusing on domestic products and from focusing on product categories that have low variability. The number of products also has a large effect in the simulations, moving from a portfolio of 10 products to one of 20 products cuts standard deviation of cash flows in relation to mean cash flows by more than half. The concentration of import origins plays a minor quantitative role on risk/return profiles in this market.     

Making and Mending your Nets: Managing Relevance, Participation and Uncertainty in Academic–Practitioner Knowledge Networks

Making and mending your nets is concerned to examine, from an actor–network theory perspective, how the relevance debate concerning research and teaching is a significant non‐human actor in the development and management of industry–academic networks associated with UK business schools. By significant, we do not imply the most important because it is only one of many human and non‐human actors that may arouse interest, be problematized, enrolled and/or mobilized for such networks to become ‘obligatory passage points’ and ultimately irreversible collective assemblies. The paper then utilizes actor–network theory as a framework for examining our primary empirical research on academic–practitioner knowledge networks – nets that require a continuous making and mending in managing relevance, participation and uncertainty. We argue that the actor–network framework is more compatible than alternative knowledge diffusion or transfer models with the data we have collected on academic–practitioner knowledge networks in the UK. In accounting for the dynamic instability and precariousness of knowledge networks, it avoids raising false expectations about business knowledge and its relevance or effectiveness. If knowledge in the physical sciences and engineering unfolds slowly and unevenly in the face of many disputes, disruptions and setbacks, as actor–network theory has claimed, then how much more likely is this to be the case in the social sciences? Consequently there should be no expectations of one‐to‐one, direct causal chains between knowledge production and application, as some business school critics seemingly demand.     

Managing knowledge in the healthcare sector. A review

Over the past decade, knowledge management (KM), as a concept and a set of practices, has penetrated into the fabric of organizational and managerial processes in the healthcare sector, which has been the site of numerous innovative KM practices. As a result scholars from a range of academic (and non‐academic) fields have begun to document how KM is conceived and practised in health care, what the recurrent issues are and how they can be addressed. The purpose of this paper is to review the current literature on KM concepts, policies and practices in the healthcare sector. Based on the analysis of the most relevant contributions in the last six years, three overarching themes that have occupied the interests of authors are identified and discussed: the nature of knowing in the healthcare sector, the type of KM tools and initiatives that are suitable for the healthcare sector, and the barriers and enablers to the take up of KM practices. The paper concludes with some considerations on what the literature tells us about the state of the art and the future of KM in this important sector of Western economies.
