Abstract
This paper studies heterogeneous precautionary saving behavior under rational inattention. In the model, consumers face uninsured capital income risk, have CRRA preferences, and suffer from an information-processing capacity constraint. For given attention devoted to capital income risk, I solve for the optimal consumption-saving choices and show that the expected utility from consumption is increasing with the amount of attention. Furthermore, I solve for the optimal attention choice and find that households with more initial wealth would pay less attention to capital income risk. As a result, wealthier households have higher perceived uncertainty in their future capital income and display precautionary motive by saving at higher rates. I also provide empirical evidence to support these results by using data from 2016 wave of the Survey of Consumer Finances.
