Inattentiveness and the Investment Channel of Monetary Policy
IMF
2025.02.06
How does rational inattention interact with financial frictions? I provide new empirical evidence from survey data suggesting that this interaction likely plays a critical role in understanding macroeconomic dynamics. In a simple model, I demonstrate that financially constrained firms tend to be more attentive to economic conditions, consistent with my empirical findings. Embedding this mechanism into a DSGE model, I show that the aggregate investment response to a monetary policy shock depends on this interaction. The model further predicts that credit-constrained firms reduce their investment after an expansionary shock due to tighter borrowing constraints and higher production costs, a prediction I empirically confirm.
