بی توجهی منطقی و پویایی مصرف و ثروت در تعادل عمومی

We propose a recursive utility version of a basic Huggett (1993) model to study the implications of rational inattention (or RI, Sims, 2003, 2010) for the cross-sectional dispersion of consumption and wealth (relative to income) in general equilibrium. We find that incorporating RI can significantly improve the model's predictions in both dimensions in general equilibrium. In addition, we find that intertemporal substitution plays an important role in determining the two key dispersion moments via affecting the degree of optimal attention in equilibrium. Finally, we show that alternative models that rely on habit formation, incomplete information about current income, or borrowing constraints are not consistent with the facts we document.
