This is a completely different vision from that currently used in most economic models. This view implies new challenges and opportunities for policy and managing economic crises. The dynamics of such models inherently involve sudden and sometimes dramatic changes of state. Further, the tools and approaches we use emphasize the analysis of crises rather than of calm periods. In this they respond directly to the calls of Governors Bernanke and Trichet for new approaches to macroeconomic modelling.30application/pdfeng© The AuthorsInterbank marketuncertaintyriskequilibriumrationalitycriticalitysimulationA complex systems approach to constructing better models for managing financial markets and the economyresearch articleMatemáticas10.1140/epjst/e2012-01696-9open access2951324The European Physical Journal.Special Topics214AR/0000011332
