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.

Prior research on international diversification has focused primarily on multinational enterprises (MNEs) from developed economies, such as the U.S. and other developed nations. As an increasing number of MNEs are now located in emerging economies, new theoretical frameworks are needed to better understand the motivations of these MNEs to diversify internationally. This paper contributes to the theory development of MNEs by examining the characteristics of international diversification by business groups from emerging economies. Using the resource-based view (RBV) of the firm and organizational learning theory, we suggest that the international diversification motives of business groups from emerging economies vary by host country context. Business groups from emerging economies are more likely to enter developed economies (rather than other emerging economies) when their primary aim is exploring new resources and capabilities, and more likely to enter other emerging economies (rather than developed economies) when their primary aim is to exploit existing group resources and capabilities. We also suggest that these motives influence business-group performance. We identify two important moderators of these relationships: product diversification and social capital. Because of the importance of the business-group organizational form in emerging economies, understanding business-group international diversification may lead to improved MNE theory.

We combine insights from the strategic management and international business literatures in order to explore the moderating role of business group characteristics on the link between innovation and internationalization in the context of the pharmaceutical sector in India. We test our three hypotheses on a sample of 219 Indian pharmaceutical firms affiliated with business groups, over a five-year period (2005–2010) in a panel of 1,096 firm-year observations. Results indicate that, contrary to our contention, research expenditure is negatively associated with export intensity, implying that firms in the Indian pharmaceutical sector may face a trade-off between investing in innovation and international expansion. As expected, business group characteristics significantly impact the strength of the relationship between innovation and internationalization. Theoretical and practitioner implications are discussed.

Business groups often contain banks or near banks that can protect group firms from economic shocks. A group bank subordinate to other group firms can become an “organ bank” that selflessly bails out distressed group firms and anticipates a government bailout. A group bank subordinating other group firms can extend loans to suppress their risk taking to default risk, preserving risk-averse low-productivity zombie firms. Actual business groups can fall between these polar cases. Subordinated group banks magnify risk taking; subordinating group banks suppress risk taking; yet both distortions promote business group firms’ survival. Limiting intragroup income and risk shifting, severing banks from business groups, articulating Business Group Law, or dismantling business groups may mitigate both distortions but also limits business groups’ internal markets, which are thought to be important where external markets work poorly.

We argue that the United States has experienced a decline of economic, political, and military power since the 1970s, and that this decline can be attributed in part to the fragmentation of the American corporate elite. In the mid-twentieth century, this elite – constrained by a highly legitimate state, a relatively powerful labor movement, and an active financial community – adopted a moderate and pragmatic strategy for dealing with the political issues of the day. The “enlightened self-interest” of corporate leaders contributed to a strong economy with a relatively low level of inequality and an expanding middle class. This arrangement broke down in the 1970s, however, as increasing foreign competition and two energy crises led to spiraling inflation and lower profits. In response, the corporate elite waged an aggressive (and ultimately successful) assault on government regulation and organized labor. This success had the paradoxical effect of undermining the elite’s own sources of cohesion, however. Having won the war against government and labor, the group no longer needed to be organized. The marginalization of the commercial banks and the acquisition wave of the 1980s exacerbated the fragmentation of the corporate elite. No longer able to act collectively by the 1990s, the corporate elite was now incapable of addressing issues of business and societal-wide concern. Although increasingly able to gain individual favors from the state, the elite’s collective weakness has contributed to the political gridlock and social decay that plague American society in the twenty-first century.

Business groups have become a significant phenomenon in the evolution and functioning of emerging markets. They also provide important partnership opportunities to foreign firms when they enter these markets. Yet, business groups have not received sufficient attention in the international marketing literature. In this paper, we provide an overview of the theories that explain how business groups function and evolve in emerging markets and generate propositions from that theory. We also present evidence on business group evolution from one emerging market, Turkey. Our work should inspire research questions for future study.

This paper provides a primer on European multinational business groups (BGs) and their subsidiaries. Firms in these BGs appear to have higher sales performance than firms in domestic groups (15% higher). This leads us to investigate which elements increase the likelihood that a group will transition towards multinational status. BGs’ characteristics matter for foreign acquisition: groups becoming multinational are usually larger, have a more hierarchical structure with respect to the number of layers in a group, and are more diverse in terms of sectors. Groups tend to expand into bordering countries or countries providing particular advantages, such as a large internal market. The first acquisition is a corporate-level decision that appears to be made by the group’s controlling firm and is often a diversification into a different industry.

Business group affiliation seems to make a firm more opaque. The benefits of group affiliation (internal market transactions) and the negative aspects of group affiliation (agency problems of group control) both may make group firms more opaque than non-group firms. Using the opacity index developed by Anderson, Duru, and Reeb (2009), this paper reports that Korean group firms are more transparent than non-group firms after the Asian financial crisis (1997–1998) and this leads to better performance of group firms. The improved transparency results from disappeared internal market benefits and diminished agency problems. These results are robust after controlling for the size of internal markets of groups, industry diversification, the existence of group inside financial institutions, and endogeneity.

This study investigated the association between structural conditions and social incentives and their effect on the ethnic composition of mobile social networks. Regarding structural conditions, we examined the role of the ethnic group’s size, socioeconomic status, and heterogeneity of the city in which the business was located. Regarding social incentives, we investigated the social diversification hypothesis, which expects that residentially and socially segregated minority groups will take advantage of mobile communications to diversify their mobile communication ties with outgroup members.

Two data sets were used. The first was the aggregation of the mobile communication patterns of business customers as measured by one of Israel’s mobile phone operators in April 2010. The database included 9,099 call data records. The second was a data set of the social characteristics of 103 Israeli cities from the Israeli Bureau of Statistics. Both data sets were merged according to the place of residence of each customer.

Israeli Arab businesses in homogeneous Jewish and mixed cities operate in an environment with more structural opportunities to create outgroup ethnic ties than Arab businesses in homogeneous Arab cities. Jewish businesses in ethnically mixed cities have more outgroup mobile ties than comparable businesses in homogenous Jewish cities.

We expand previous models and suggest a structural diversification approach in which ethnic mobile social networks vary across homogeneous and ethnically mixed cities. These variations result in different social incentives as the diversification approach assumed, as well as different structural conditions, as the structural approach indicates.
