有人认为,通过在离散时间新凯恩斯(NK)模型中结合使用积极的货币政策和被动的财政政策,可以实现局部均衡确定性,该模型包括一个在政策反应中具有时滞的财政政策规则。然而,即使在这样的政策下,在生产函数中包含金钱的模型中也可能出现不确定性。在本文中,我们首先证实了这些结果在无政策滞后的连续时间NK模型中成立。此外,我们提出了能够避免不确定性的财政政策滞后的情况。
It has been suggested that local equilibrium determinacy can be achieved by applying active monetary policies combined with passive fiscal policies in discrete-time New Keynesian (NK) models that include a fiscal policy rule with a time lag in the policy response. However, indeterminacy can occur even under such policies in models with money in the production function. In this paper, we first confirm that these results hold in a continuous-time NK model without a policy lag. Furthermore, we present the case of a fiscal policy lag that is capable of avoiding indeterminacy.
