Business Groups and Their Types

Abstract:     
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.
