We find that chaebols grow vertically (that is, pyramidally) as the family uses well-established group firms ("central firms") to set up and acquire younger firms that have low profitability and high capital requirements. Chaebols grow horizontally (that is, using direct family ownership) when the family acquires firms that are highly profitable and require less capital. Our evidence suggests that the (previously documented) lower profitability of pyramidal firms is partly due to a selection effect (e.g., the family optimally places low profitability firms in pyramids). To show this, we examine insta...
