Both traditions, though, were eclipsed by the Chicago school of “rational expectations,” which has dominated mainstream economics for the last twenty-five years. With economic agents supposedly possessing perfect information about all possible contingencies, systemic crises could never happen except as a result of accidents and surprises beyond the reach of economic theory.
但这两大流派都在芝加哥学派“理性预期”理论的光芒下黯然失色，后者在过去25年内统治了整个主流经济学界。该理论认为只要所有经济部门都能充分了解所有可能出现的突发事件，那么除非出现某些超出现有经济学理论范畴之外的意外事件，否则系统性危机永远不会发生。
