This paper describes a hierarchy with peer hiring to explore the reasons behind the management rule “A’s hire A’s and B’s hire C’s”. Workers are promoted based on talent and therefore like to hire less talented co-workers. This is why B’s hire C’s. The same logic should cause A’s to hire B’s, but there is a trade-off in the model: A’s are more likely to be promoted, and a manager profits from more talented subordinates. If this effect is strong enough, then indeed A’s hire A’s.
