Economic Networks Structural Analysis

An introduction to economic networks, exploring how economies can be analysed as systems of interconnected entities like households, firms, and banks. It covers foundational graph theory and linear algebra concepts necessary for understanding network structures and dynamics. The text examines various applications, including production networks, financial networks, and Markov chains as models for economic phenomena like income distribution and belief propagation, often utilising concepts like network centrality and spectral theory. Finally, it explores nonlinear interactions and optimisation problems within these networks, including shortest path problems and optimal transport, often framed as linear programming problems.
