Business Groups and Their Types
20 Pages Posted: 6 Dec 2007
We clarify what business groups are and analyze their various types. We first distinguish business groups from other types of firm networks based on the strategic relationships among companies; business groups are defined as those networks that exhibit unrelated diversification under common ownership. We then separate business groups into three types based on their ownership: family-owned, widely-held, and state-owned. We argue that each type has different agency costs and diversification logics. As a result of these differences, their performance varies, with family-owned business groups outperforming widely-held ones, and these in turn outperforming state-owned business groups.
