Sargent and John Stachurski a1 aUK:bCambridge University Press,c2024. a244p. aIt has become increasingly clear that economies can fruitfully be viewed as networks, consisting of millions of nodes (households, firms, banks, etc.) connected by business, social, and legal relationships. These relationships shape many outcomes that economists often measure. Over the past few years, research on production networks has flourished, as economists try to understand supply-side dynamics, default cascades, aggregate fluctuations, and many other phenomena. Economic Networks provides a brisk introduction to network analysis that is self-contained, rigorous, and illustrated with many figures, diagrams and listings with computer code. Network methods are put to work analyzing production networks, financial networks, and other related topics (including optimal transport, another highly active research field). Visualizations using recent data bring key ideas to life. aChapter 1: Introduction Motivation Spectral Theory Probability Graph Theory Chapter 2: Production Multisector Models General Equilibrium Additional Spectral Theory Chapter 3: Optimal Flows Shortest Paths Linear Programming and Duality Optimal Transport Chapter 4: Markov Chains and Networks Markov Chains as Directed Graphs Asymptotic Behavior Chapter 5: Nonlinear Interactions Fixed Point Theory Financial Networks Appendices Appendix A: Math Review Appendix B: Solutions to Selected Exercises aEconomics/Theory Aspects aStachurski, John
