Rational Inattention and the Business Cycle Effects of Productivity and News Shocks
构建了一个包含理性疏忽的真实商业周期模型,发现该模型能解释就业、投资和产出增长的持续性以及新闻冲击后的协同运动,而标准RBC模型则不能。
We solve a real business cycle model with rational inattention (an RI-RBC model). In the RI-RBC model, the growth rates of employment, investment, and output are about as persistent as in the data, with an amount of inattention consistent with survey data on expectations. Moreover, consumption, employment, and output move in the same direction in response to news about future productivity. By contrast, the baseline RBC model produces neither persistent growth rates nor business cycle comovement after news shocks.
