[Question] What are good models of collusion in AI?

I’m working on a paper and accompanying blog post examining theories of collusion in the context of oligopolistic firms in economics, to see what those models would say about AI safety scenarios (e.g. values handshakes, acausal negotiation, etc.). I’m very familiar with the econ literature, but I want to make sure I’m drawing on the state-of-the-art in AI theory as well. Any advice on which sources I should look at?
