带“金融加速器”的RBC模型

本文将在RBC模型引入“金融加速器”来分析金融信贷市场中存在的信息不对称对经济所造成的影响。我们采用数值模拟的方法,具体分析了在引入“金融加速器”后技术冲击对经济造成的影响,并且将模拟出来的结果和传统的RBC理论中数值模拟的结果进行对比。我们发现,由于金融加速器的存在,加大了波动对经济的影响,很可能一点小的波动都会对经济带来极大的影响。

By introducing 'financial accelerator' into Real Business Cycle model, this paper studies the effect of asymmetric information on economy. Comparing with the traditional RBC model which does not think about the 'financial accelerator', it is found that the 'financial accelerator' enlarges the effect of economic fluctuation on economic performance and even a small fluctuation may affect economic performance largely.
