This appendix is organized as follows.  Section A illustrates another case of wealthy hand to mouth behavior which completes the discussion of Section 4.1 in the main text. Section B contains more details on our definitions of liquid and illiquid wealth from the SCF and on the measurement of hand-to-mouth households.  Section C describes certain steps of the model's calibration omitted from the main text.  Section D contains a robustness analysis on the baseline rebate experiment.  The numerical computation of the model and the simulation of the policy experiments are delineated in Section E.
