This paper studies the implications of rational inattention (RI) for asset pricing in a LQ-PIH model. We find that RI increases the size of risk adjustment to asset prices and expected excess returns, which helps resolve extant asset pricing puzzles.

In this paper, we consider a finite-horizon model with the time-additive utility and the time varying discount rate. With the assumption of the concavity of absolute risk tolerance, the concavity of the consumption function has been proved. This result significantly broadens the conclusion of...
