On the Emergence of Hierarchies as Governance Structures — •Diana Mangalagiu¹ and Radel Ben-Av² — ¹Reims Management School, 59, rue Taittinger, 51061 Reims, France — ²Racah Institute Of Physics, Givat Ram Hebrew University Jerusalem 91104 Israel

We discuss a model for the emergence of hierarchies and firms. The hierarchy, as governance structure is a contractual construction. It is conceived not as a stand-alone entity, but is to be compared with alternative modes of governance. In our model, the agents represent individuals in the market. They are heterogeneous, cognitive, self-interest and their only goal is to increase their own achievements. Initially, the agents are isolated. The model dynamics allows the use of contracts between agents in order to increase the overall utilization. The model rewards collaboration. The collaboration is achieved through No-dqemployment contractsNo-dq between the initially isolated agents. There is a limitation on the bandwidth of communication between the agents, which forces the agents to have only a limited number of connections. When an opportunity in the market is optimally executed only with a large number of agents, a hierarchy is bound to appear as a favourable outcome of the dynamics. As a result a tree-graph of relations between agents can emerge. We investigate the contracts that are generated in the model. Some forms of contract facilitate the emergence of hierarchies while others not. In addition, we investigate the emerged hierarchies as a function of the different contract parameters (attributes, renewal interval, incentives intensity).
