In this book, J. Doyne Farmer, a pioneer in complexity science and chaos theory, argues for a new economic paradigm that uses complex systems, big data, and advanced computing to build more realistic economic models. Farmer blends scientific insight, personal experience, and critical analysis to explain how traditional economic approaches have fallen short in addressing real-world challenges like inequality, financial instability, and climate change, and outlines a vision for how economics can become a more effective science for understanding and shaping global economic dynamics
