Purpose – This chapter aims to identify and address methodological issues inherent in business group studies, especially within the context of South Korean chaebols, many of which have been exalted as most remarkable cases of business groups.

Design/Methodology/Approach – After reviewing the theoretical background and the evolution of chaebols, the authors identify methodological issues focusing on the constructs of major interest to researchers, which need careful treatment for enhancing the internal and external validity of studies on business groups in general and chaebols in particular.

Findings – Any sample of business groups must be composed based on accurate definitions rather than conventional lists readily available, in accordance with the research purpose. Identifying and quantifying the strategic and structural characteristics of business groups should be accompanied by an understanding of the various types of economic organizations. The uniqueness of business groups in each country should also be considered, especially in conducting comparative analyses and generalizing research findings. Measuring performance needs more careful attention given the increasing complexity in many business groups. The embeddedness of business groups in a specific society as well as their coevolution with the institutional context urges researchers to employ more qualitative or ethnographic methods.

Originality/Value – The authors suggest alternatives through which we can cope with the methodological issues, and make suggestions for future research. As business groups continue to play a significant role in many emerging economies, continuing efforts to elaborate methods will contribute to improving the value of our scholarly work in both academic and practical dimensions.

Welcome to the eighth volume of Research Methodology in Strategy and Management. The theme of this volume is West Meets East: Building Theoretical Bridges. It complements the seventh volume West Meets East: Toward Methodological Exchange. The two volumes together examine the relevance of Western theories and methods in the Eastern research context. In particular, this volume examines the key theoretical areas that strategic management research draws from to understand how managers can lead their companies to achieve competitive advantage in the increasingly globalised economy. We not only focus on the extent to which theories developed in the West can be applied in the understanding of business practice and performance in the East, but also explore methods for developing new insights and theories rooted in the Eastern business practice.

Summarizes several strategic briefings, conference presentations and reports on the topic of logistics management. Covers in turn logistics in China and Japan, including a profile of Braun Electric; methods of improving the supply chain, highlighting new technology, the “bullwhip effect” of distorted information and a case study of Tektronix; logistics in retailing, including direct mail in Japan, home shopping and distribution networks; and applications of the Internet in the logistics field, focusing on “knowledge logistics” (electronic publishing). Concludes with a summary of research conducted by McKinsey which suggests that doing business in a world of plentiful and cheap interactions will require new skills and new ways of thinking and those who anticipate and understand the fundamental nature of the changes will be best placed to exploit the opportunities.

The policy choices of Eurasian states whether to form a coalition along with the “Eurasia Initiative” can be explained by the cooperative game theory. While the each bilateral relationship before making a binding agreement seems to be a non-cooperative game, the coalitions with many other states through a binding agreement of Mega-FTA would be a cooperative game. Despite the lack of numerical data, this study at least tries to show the possibility of applying the game theory to analyze the “Eurasia Initiative” and it’s the impacts of Mega-FTAs on this ambition. While the Eurasia Initiative necessarily involves some economic projects requiring enough investment promotion, Korea can strategically set up the policies linked with the development of Mega-FTAs. To utilize the investment promotive effect of Mega-FTAs, Korea has to assure that the core of the cooperation game would be the grand coalition of a Mega-FTA. If it continues to search for the best policies to maximize the superadditivity of this cooperative game, Korea will finally be able to achieve the co-promotion of Mega-FTAs and the Eurasia Initiative.

The purpose of this paper is to study whether a fast supply network structure interacts with customer integration (CI) by positively moderating the relationship between CI and efficiency performance.

The authors developed two hypotheses, incorporating dimensions of CI, fast supply network structure and efficiency performance. The hypotheses are tested through a hierarchical regression analysis using data from a sample of 200 manufacturing plants.

CI alone is not enough to guarantee cost reductions because a fast supply network structure acts as a moderator of the CI‐efficiency relationship. The role of this moderator is twofold. On the one hand, it interacts with CI, strengthening the positive impact of CI on efficiency through a positive complementary effect. On the other hand, if the supply network structure is not intended to support fast lead times, the impact of CI on efficiency can be hindered and, in extreme cases, CI can even make efficiency worse.

Efficiency maximization requires levering simultaneously on CI and the supply network structure, rather than investing and acting on CI only. Managers should carefully weigh up the supply network structural context before embracing a CI program, because adopting CI in a wrong context could amplify a series of problems (e.g. nervousness of plans) and offset CI benefits in terms of efficiency.

This study provides an original contribution to the literature on the relationship between CI and efficiency by adopting a contingency perspective, namely assuming that the relationship between supply chain practices and performance is contingent upon how supply networks have been designed. Accordingly, this research questions the assumption that CI always improves efficiency, by analysing the complementary effect between CI and a fast supply network structure. This provides a number of original implications for the interpretation of the relationship between CI, supply network structure and efficiency.
