In a perfectly rational world the economy is characterised by an average agent (consumer, producer, investor, etc.), who is a perfect optimiser with rational expectations about the future. But the real world is much more complex, and socio-economic systems are highly influenced by people’s differing expectations and adaptive behaviours.
 

Panics, bubbles, crashes, herding. Crises like these are nightmares for policy-makers and citizens alike. The 2008 fall of Lehman Brothers, for example, triggered a cascade of events that had a profound impact not just on banks and stock markets, but also on the incomes and well-being of people around the world.

Developing more realistic economic models

The goal of this research theme is to develop a more realistic financial-economic, agent-based, network model that policy-makers can use to predict or manage socio-economic crises. As a starting point, we are investigating whether complexity modelling tools that have been successful in the natural sciences can be applied to complex socio-economic systems.

Understanding the complexity of economic systems requires drawing on a wide range of disciplines including not only economics but also for example psychology, sociology, physics and computational science.
