Abstract: This study investigates whether the Federal Reserve (Fed) should care about inequality. We develop a Heterogeneous Agent New Keynesian (HANK) model, which generates empirically realistic inequalities and business cycle properties observed in the U.S. data. We consider the income Gini coefficient in a monetary policy rule to see how an inequality-targeting monetary policy affects aggregate and disaggregate outcomes, as well as economic welfare. We find that a monetary policy rule with an explicit inequality target can be welfare improving, even if inequality becomes volatile. In particular, the policy reform can improve the welfare of the poorest the most. Finally, we demonstrate the feasibility of a subgroup targeting monetary policy as a tool for an implementable inclusive monetary policy.
