在财政货币政策交互作用的早期研究中,博弈论模型进路研究依赖于经济结构模型的理论限制和约束;基于特定政策组合的研究只是财政货币政策实践的片面和局部刻画,因而渠道机制有限;传统新凯恩斯主义动态一般均衡模型中财政政策的作用非常有限。因而,放松消费者假设,增加财政变量,拓展新凯恩斯主义动态一般均衡模型,融合更多李嘉图等价不成立特征,为财政货币政策交互作用的总需求尤其是总供给渠道机制正规建模,并以此进行实证研究,成为财政货币政策交互作用研究符合学科发展趋势且可用以政策评价与设计的首选。
In the early research on the interaction of fiscal and monetary policies, the research on the game theory model relies on the theoretical limitations and constraints of the economic structure model. The study based on the specific policy portfolio is only one-sided and partial depiction of the practice of fiscal and monetary policy, so the channel mechanism is limited. The role of fiscal policy in the traditional New Keynesian dynamic general equilibrium model is very limited. Thus, the relaxation of consumer hypotheses, the increase of financial variables and the expansion of the general Keynesian dynamic equilibrium model, the fusion of more Ricardian equivalence is not established characteristics, the total demand for fiscal and monetary policy interaction, especially the general supply channel mechanism formal modeling, and This empirical study has become the first choice of research on the interaction of fiscal and monetary policies that is in line with the development trend of disciplines and can be used for policy evaluation and design.
