The role of informal institutions in corporate governance: Brazil,Russia, India,and China compared

This paper argues that the role of informal institutions as well as formal ones is central to understanding the functioning of corporate governance. We focus on the four largest emerging economies: Brazil, Russia, India, and China—commonly referred to as the BRIC countries. Our analysis is based on the Helmke and Levitsky framework of informal institutions and focuses on two related aspects of corporate governance: firm ownership structures and property rights; and the relationship between firms and external investors. We argue that for China and some states of India, “substitutive” informal institutions, whereby informal institutions substitute for and replace ineffective formal institutions, are critical in creating corporate governance leading to enhanced domestic and foreign investment. In contrast, Russia is characterized by “competing” informal institutions whereby various informal mechanisms of corporate governance associated with corruption and clientelism undermine the functioning of reasonably well set-out formal institutions relating to shareholder rights and relations with investors. Finally Brazil is characterized by “accommodating” informal institutions which get around the effectively enforced but restrictive formal institutions and reconcile varying objectives that are held between actors in formal and informal institutions.     

Towards an agenda for institutions of foresight

There are some 200 or 300 purpose-built institutions worldwide whose central focus is the future,¹ but remarkably little comparative knowledge exists about them. An international agenda of research and action is needed to improve understanding of these institutions of foresight (lOFs) and to promote the continued development of their symbolic power and social influence. This report, which outlines a framework for investigating the structure, function and effectiveness of the lOFs and presents some initial proposals for practical action, is intended as the first step in the creation of such an agenda.     

The Dynamics of Industrial Clustering in Biotechnology

This paper is a study of the process by which industrial clusters form. It identifies the forces of attraction to new companies to a cluster in biotechnology in the U.S. as it grows. It uses a model of entry of new firms into the industry to measure the degree of attraction to those new firms of the presence of an existing cluster at a particular location. The paper finds that the main agent of attraction to new firms to enter the biotechnology industry is the presence of a strong science base at that location. This provides a greater magnet than the strength of any particular sector of the industry. In terms of attraction between different sectors within the industry, the paper finds that there is positive attraction and feedback between a group of sectors in the biotechnology industry – namely the therapeutics, diagnostics and the equipment/research tools sector. However in other sectors of the industry – chemicals, food and to some extent agriculture – there is much less attraction and interaction between them. This implies that clusters of firms tend to develop only in particular sectors of the industry and positive feedback mechanisms do not extend to other parts of the industry.     

Value creation and the probability of success in merger and acquisition transactions

This paper presents and tests a hypothesis that expands existing explanations of value creation in merger and acquisition (M&A) transactions. The main premise is that value creation is determined by not only the target’s pre-acquisition value, as indicated by numerous studies in extant literature, but also by the acquirer’s competency (among other factors) demonstrated by their pre-merger financial ratios. The paper shows that M&A transactions create value in the longer-run and the gain is commensurate with the acquirer’s historical performance and the target’s pre-acquisition value. Further, the paper employs statistical procedures and model-building techniques in order to develop and validate parsimonious Altman-style predictive models. The models reasonably identify successful M&A deals and are statistically significant and consistent with a few existing theories. Specifically, the evidence on liquidity supports internal capital markets hypothesis but does not support the theories of agency problems, while the evidence on financial leverage supports the view that lower debt enhances corporate control.     

THE INTELLECTUAL STRUCTURE OF SUPPLY CHAIN MANAGEMENT: A BIBLIOMETRIC APPROACH

Now that supply chain management has a two‐decade research history, it is possible to examine the literature to identify whether there is any latent intellectual structure using bibliometric tools. The study applies a citation and co‐citation approach to reveal four clusters of research that have emerged. One cluster has strong ties to the logistics field, with primarily conceptual articles. A second cluster finds its roots in operations research, and consists mainly of modeling articles. The application of multidimensional scaling, cluster analysis, and factor analysis on co‐citations demonstrated a clearly identifiable structure. The structure is examined and implications for the future development of supply chain research are discussed.     

5 pillars of clinical integration

Implementing an effective clinical integration program requires deliberate investment of time and resources in five key areas: Physician leadership, Physician-led care management, Quality monitoring, Patient information and data sharing, Payer engagement.     

Researching the Opportunities and Challenges for Women in Supply Chain

In this editorial, we call attention to the underresearched issue of women in logistics and supply chain management. Despite growing interest in the field and the much recognized gap in talent, women remain underrepresented in the field—and particularly in the senior ranks. We explore some of the reasons offered in existing literature for this deficiency. While progress is noted, much work remains to be carried out. Rigorous research can be instrumental in illuminating the path forward. Possible avenues for research, including an array of research questions, are presented in this call for action.     

Organizational Changes Resulting from the Privatization of State Enterprises

Agency and public choice theories, though commonly used, can only provide a static approach to the study of privatization and often neglect the cultural, contextual and organizational settings of the enterprises affected by privatization. The authors present a new model which can be used to understand the organizational processes involved in a successful privatization. This article analyses the academic literature on privatization, describes the cases of two privatized Swedish companies and then offers suggestions for further research.
