We explore the nature of Business Groups, that is network-like forms of hierarchical organization between legally autonomous firms spanning both within and across national borders. Exploiting a unique dataset of 270,474 headquarters controlling more than 1,500,000 (domestic and foreign)...

The first striking feature is that ownership of the average UK company is diffuse: a coalition of at least eight shareholders is required to reach an absolute majority of voting rights. Even though the average firm has a dispersed ownership, the reader should bear in mind that there are about...
