Business Groups in Emerging Markets: Paragons or Parasites?

Tarun Khanna, Yishay Yafeh


Diversified business groups, consisting of legally independent firms operating across diverse industries, are ubiquitous in emerging markets. Groups around the world share certain attributes but also vary substantially in structure, ownership, and other dimensions. This paper proposes a business group taxonomy, which is used to formu-? late hypotheses and present evidence about the reasons for the formation, prevalence, and evolution of groups in different environments. In interpreting the evidence, the authors pay particular attention to two aspects neglected in much of the literature: the circumstances under which groups emerge and the historical evidence on some of the questions addressed by recent studies. They argue that business groups are responses to different economic conditions and that, from a welfare standpoint, they can some-? times be paragons and, at other times, parasites. The authors conclude with an agenda for future research.
