A widely held view among the general public is that the Great Depression and the current financial and economic crisis triggered by the subprime debacle are evidence that economics is not a science in the same sense that mathematics or mechanics are sciences. The research reported in this symposium is proof of the contrary. It illustrates how mathematical models of the economic and financial worlds developed from first principles before the crisis can help us understand a world in crisis and how we got there. Regulators call for the monitoring of systemic risk. This can only mean the study of general equilibrium. Economics is a difficult science with many still unchartered territories. It is through more research of the kind reported in the articles published in this symposium that our understanding of the operations of modern economies will be able to improve.
