Monetary and Fiscal Policy under Imperfect Knowledge

该项目提出了一个议程，探讨不完善的知识对宏观经济动态和稳定政策的影响。学习动力学是理解总体波动的核心，在此期间，代理人对其环境的信息有限，就像全球金融危机期间和之后的情况一样。议程包括两条调查线索。第一个发展的理论问题，在不完善的知识下的货币和财政政策的设计和实施。第二部分列举了任何宏观经济模型都应该考虑的可能信念类别的经验证据。

This project lays out an agenda exploring the consequences of imperfect knowledge for macroeconomic dynamics and stabilisation policy. Learning dynamics are central to understanding aggregate fluctuations in periods during which agents have limited information about their environment, as has been the case during and after the Global Financial Crisis. The agenda comprises two lines of inquiry. The first develops theoretical issues relating to the design and implementation of monetary and fiscal policy under imperfect knowledge. The second adduces empirical evidence on the classes of possible beliefs that any macroeconomic model should account for.
