Toward a political economy of complex interdependence

How should we theorize about international political economy in an era of complex interdependence? The global economy is much more interdependent today than it was 40 years ago. As a result, there is a widening appreciation that we need new theoretical tools to understand how complex interdependence arose, how it operates, and where it might be headed. I argue that to develop such tools, we must embrace new theoretical logics that more readily accommodate and explain change. I develop this point by drawing on complexity theories, ecology, and information theory. I first develop the core elements of a complexity-based approach and contrast it to the central assumptions of the Open Economy Politics approach. I then illustrate this complexity-oriented approach by using the logic of coevolution and the information-entropy cycle to explain key elements in the development of the 2008 global financial crisis.
