资源简介:
How does an economy behave if (1) fundamentals are truly hump-shaped, exhibiting momentum in the short run and partial mean reversion in the long run, and (2) agents do not know that fundamentals are hump-shaped and base their beliefs on parsimonious models that they fit to the available data? A
若(1)基本面(fundamentals)确实呈驼峰形,短期内表现出动量效应(momentum)而长期内呈现部分均值回归(partial mean reversion);(2)经济主体(agents)并不知晓基本面为驼峰形,而是基于其拟合可用数据得到的简约模型(parsimonious models)形成信念,那么经济将如何运行?A
