Abstract
We present three hierarchical models for the evolution of compositional language. Each has the basic structure of a two-sender/one receiver Lewis signaling game augmented with executive agents who can learn to influence the behavior of the basic senders and receiver. With each game, we move from stronger to weaker modeling assumptions. The first game shows how the basic senders and receiver might evolve a compositional language when the two senders have pre-established representational roles. The second shows how the two senders might coevolve representational roles as they evolve a reliable compositional language. Both of these games impose an efficiency demand on the agents. The third game shows how costly signaling alone might lead role-free agents to evolve a compositional language.
