讲座内容摘要:

We provide a dynamic new Keynesian model in which entrepreneurs face uninsurable idiosyncratic investment risk and credit constraints. Government bonds provide liquidity service and raise net worth. Multiple steady states with positive values of public debt can be supported for a given permanent deficit-to-output ratio. The steady-state interest rates are less than economic growth and public debt contains a bubble component. We analyze the determinacy regions of policy parameter space and find that a large set of monetary and fiscal policy parameters can achieve debt and inflation stability given persistent fiscal deficits.

我们提供了一个动态的新凯恩斯主义模型,在这个模型中,企业家面临着不可保险的特异性投资风险和信贷约束。政府债券提供流动性服务并提高净资产。在给定的永久性赤字与产出比率下,可以支持多个公共债务为正值的稳定状态。稳态的利率低于经济增长,公共债务包含泡沫成分。我们分析了政策参数空间的决定性区域,发现在持续的财政赤字的情况下,一大套货币和财政政策参数可以实现债务和通货膨胀的稳定。
