A Dynare toolbox for social learning expectations
本文开发了一个Dynare工具箱，用于求解带有社会学习预期的线性状态空间模型，并以新凯恩斯模型为例分析了最优货币政策规则。
Social learning (SL) is a behavioral model in which expectations and the resulting aggregate dynamics stem from the interactions of a large number of heterogeneous agents. Nonetheless, this framework has so far lacked a parsimonious development with a general-solution method. This paper bridges this gap and introduces a Dynare toolbox to solve any linear state-space model with SL expectations, opening up a wide range of potential applications. As an illustration, optimal monetary policy rules are studied in a microfounded New Keynesian (NK) model under SL and rational expectations (RE).
