I'm working on my master's thesis in industrial organization and I have a model that is based on social networks. I have had two courses about social networks (one more focused on basic industrial organization questions in networks and the other more about basic graph theory) but as I work more on the model I feel I'm not really using the network in solving the questions that arise and leaving it more as a descriptive structure, and I fear it is mostly due to ignorance.
Can anyone refer to a good book, class notes or papers that might help me learn more deeply the implications of the network structure and/or the pros and cons of modeling a problem as a network? For example on how the network structure might be helpful when trying to determine existence of equilibrium.
