NETWORK ANALYSISNETWORK ANALYSIS
1) Growth of the Network: This starts with a small number of nodes, say N and each time-step, a new node m is introduced in the network. The new node is connected to the nodes from N.
2) Preferential attachment: The choice of nodes to which m (≤M) is connected, the probability that m will be connected to a node, depends upon the connectivity of the node. 3) After t(≤T) time steps, the model evolves to a network with t + m nodes and Mt edges. The network evolves into a ‘scale variant’ state such that the degree distribution follows a power-law, with the scaling component independent of M.

In economic geography one might think of
economic magnets such as agglomeration of talent, capital, and
services.

Questions….
-How big are agglomerations, and how to measure it?
-How do they function and how can we visualise that?
-What is, from a policy point of view, the ‘dominant’ agglomeration to focus on? (geographical scale and social levels)
-Ways to integrate social network analysis and spatial econometrics?
