Inflation as a Redistribution Shock: Effects on Aggregates and Welfare

Episodes of unanticipated inflation reduce the real value of nominal claims and thus redistribute wealth from lenders to borrowers. In this study, we consider redistribution as a channel for aggregate and welfare effects of inflation. We model an inflation episode as an unanticipated shock to the wealth distribution in a quantitative overlapping-generations model of the U.S. economy. While the redistribution shock is zero sum, households react asymmetrically, mostly because borrowers are younger on average than lenders. As a result, inflation generates a decrease in labor supply as well as an increase in savings. Even though inflation-induced redistribution has a persistent negative effect on output, it improves the weighted welfare of domestic households.
