我们研究的最优政策在商业周期的设置,企业持有分散的私人信息,或理性地忽视,经济状况。信息摩擦是名义上和真实的刚性的根源。由于后者,最优货币政策不以价格稳定为目标。相反,它的目标是名义价格水平和真实的经济活动之间的负相关关系。这种逆风的倾斜有助于最大限度地提高生产效率。另一个贡献是适应的原始方法拉姆齐文学的灵活形式的信息摩擦。
We study optimal policy in a business-cycle setting in which firms hold dispersed private information about, or are rationally inattentive to, the state of the economy. The informational friction is the source of both nominal and real rigidity. Because of the latter, the optimal monetary policy does not target price stability. Instead, it targets a negative relation between the nominal price level and real economic activity. Such leaning against the wind helps maximize production efficiency. An additional contribution is the adaptation of the primal approach of the Ramsey literature to a flexible form of informational friction.
