Models of hierarchy growth

The hierarchies are found in various places, from biological organisms, to social and economic structures and countries. The talk will shortly review various kinds of hierarchy and introduce a model of hierarchy growth.
The simple model focuses on the limits of information accessible to new entrants, as opposed to popular preferential attachment models where entrants have access to information about whole system.
The behavior of the model for different information limits will be presented and implications will be discussed.
