Happening of a M&A in a market, is a like a wave that will be propagated in a system of supply chain stakeholders, clients, suppliers, competitors and shareholders. I think by progress of mathematical agent-based modelling of networks and application of graph theory, any M&A can be assessed in a context of agents(stakeholders) not just between limited players. As far as we are precise in system identification and connection of agents, we can have better estimate about gained synergy.
