| Gaia: | One prediction of the Permanent Income Hypothesis is that households who are illiquid may wish to borrow against future income when there is a positive shock to their future income process. We informally model this prediction in a two-period setting and then test it using Equifax data. We demonstrate that Democrats experience a strong, positive shock to their expectations about their future real income around the 2020 presidential election. Our difference-in-difference analysis finds that in response Democrats were 0.08% more likely to take on debt in order to buy a car, and that their outstanding auto loan balance increased by $104 on average. Compared to the rate at which Democrats purchased cars via loan prior to the election, this 0.08% increase represents a 1.37% increase in the purchase rate. We validate our results by finding a similar result holds for installment loan purchases. We show that this result is robust to our empirical assumptions. |
