Complexity economics is an interdisciplinary field between economics and complex systems that is studying economic phenomena in the context of complex systems. This approach is considering the economy as a complex system, and the web of actors and relationships in the economy displays features such as heterogeneity, emergence, non-linearity, system dynamics, near-deomposability, and many more... in other words it displays of the characteristics of a living complex system.
Another field of research in economics and complex systems comes from computational approaches to economics, such as agent-based modeling. The field of computational economics lies at the intersection between computational social science and complexity economics. Some of the most relevant research in the field can be found here.
