Tim is keen to understand how emergent behaviour and evolutionary forces shape the market and society. One of his goals to bring complexity into economics and increase the understanding of agent-based modelling as that is the only experimental tool he knows that can explore emergence and evolution arising from a heterogenous population. Modelling people as living beings that need basic necessities to survive, reproduce, and care for children are important foundations of economic models, he believes, as the population impacts the economy and vice versa. He is not well known for demonstrating that long-term supply and demand do not determine price in a complex system. He is currently writing a book about all this to be published by MacMillan.
