Perhaps current researchers can take comfort in the fact that one day the outcomes of current scientific debates may also become glaringly obvious. But in the meantime we need to struggle on before science reveals the answer to us. Conclusion Let me conclude with a forward looking perspective.
It seems obvious that globalisation and financial innovations will continue, so that complexity in the economic and financial system will continue to increase. Take the financial turmoil of the past year, to which I referred already. Obviously there is a need to tailor our policies, for example financial supervision and monetary policy, to the dynamics that we have witnessed in the financial sector.
