Economic Networks

It 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.
