题目：Nominal Rigidities, Rational Inattention, and the Optimal Monetary Policy

内容摘要：Optimal monetary policy has traditionally assigned greater importance to stabilizing prices in sectors with stickier prices, based on multi-sector models with full information or exogenous information frictions. This paper challenges the prevailing policy prescription by introducing rational inattention with endogenous information acquisition. Surprisingly, the optimal policy assigns a smaller weight to sectors with stickier prices when information acquisition is sufficiently costly. This counterintuitive result stems from the endogenous relationship between attention and nominal rigidities: firms in sectors with more flexible prices pay less attention to macroeconomic conditions. We provide empirical evidence supporting this mechanism.
