A wonderfully written piece in today’s FT Magazine by Stephen Foley, on the changing role of physicists in financial markets. A short extract below, and the full article is here (sign up may be required but is free for a certain number of articles). ‘…complex systems are not systematically predictable. They’re only predictable in some regimes…’ The […]

This New Scientist ‘Science in Society’ Briefing examines the issues. What is a complex network? Complex networks have many interconnected components which influence each other’s […]

It is built around an innovative, network-based methodology for understanding economies and their potential for  growth. It represents perhaps the most systematic and in-depth application of the ideas […]

Complexity scientists have long argued for the use of concepts such as nonlinearity and interconnectednesss to better understand economic phenomena, including growth, market failures and crashes. Ongoing research at the Harvard Center for International Development is taking this area of work forward in very promising ways. In some ways, as Tim Harford has argued, the notion […]
