Some argue that the solution is to return to the simpler economic models of the past, which yielded policy prescriptions that evidently sufficed to prevent comparable crises. Others insist that, on the contrary, effective policies today require increasingly complex models that can more fully capture the chaotic dynamics of the twenty-first-century economy.
有人认为，解决办法是回归过去比较简单的经济模型，这类模型所产生的政策药方显然足以阻止可以比较的危机。其他人坚持相反的意见，认为如今有效政策日益需要复杂模型以充分把握二十一世纪经济的混乱动态。
