Optimal inattentive length in macroeconomic models

This paper proposes an approximate solution of firm's optimal inattentive length in a standard macroeconomic model. The approximate solution conceptually fits a sticky-information model better, and predicts empirically more plausible inattentive length than the one proposed by Reis [Reis, R., 2006. Inattentive producers, Review of Economic Studies 73, 793-821].
