3. Consider a "star" network of K≥ 2 agents. Label Agent 1 as the "central" agent. (a) Suppose that all agents update according to a DeGroot process whereby they equally weight their own and their neighbors' information. Completely characterize the updating matrix A. Note that this is not the same as the adjacency matrix. (Hint: Your answer should state entries as a function of K.) (b) Agents 2,..., K are all similarly-situated in the network. What should be true of their social influence? (c) Using your answer to (b), derive the social influence for each player (Note that this will be a function of K). Comment on how the influence of the central agent changes as K increases.
