Simplifying Complexity

The dynamics of financial instability

Dec 9, 2024
Steve Keen, an accomplished economist and Honorary Professor at University College London, delves into the failures of neoclassical economics versus post-Keynesian thought. He emphasizes how complexity science and chaos theory can illuminate economic cycles of booms and busts. Keen critiques the flawed aggregation in neoclassical models and argues for integrating private debt into frameworks. He champions multi-agent modeling and government intervention in financial systems to foster stability and prevent crises, making a compelling case for rethinking economic dynamics.

Deep dives

Understanding Economy Through Complexity Science

An effective understanding of the economy can be developed by using a limited number of critical variables rather than focusing on individual agents, as suggested by Professor Steve Keen. By applying concepts from complexity science and chaos theory, it's possible to create a model that accurately reflects economic dynamics, including cycles of booms and busts. This approach challenges the traditional neoclassical view of the economy as being in a constant state of equilibrium. Instead, Keen argues for building a non-equilibrium model that better represents the fluid nature of economic interactions.
