This paper investigates the implications of heterogeneous price rigidities across sectors for the distributional and aggregate effects of monetary policy. First, we identify and characterize analytically a new set of earnings and expenditure channels of monetary policy that emerge in the...

Should central banks’ inflation targets remain set in stone? We study a dynamic mechanism design problem between a government (principal) and a central bank (agent). The central bank has persistent private information about structural shocks. Firms learn the state from the central bank’s...

This paper characterizes optimal monetary policy in a canonical heterogeneous-agent New Keynesian (“HANK”) model with wage rigidity. We develop a timeless Ramsey approach to study optimal long-run policy, time inconsistency, and optimal stabilization policy, as well as optimal policy under...

This paper characterizes optimal monetary policy in a canonical heterogeneous-agent New Keynesian (HANK) model with wage rigidity. Under discretion, a utilitarian planner faces the incentive to redistribute towards indebted, high marginal utility households, which is a new source of inflationary...

This paper studies monetary policy in a New Keynesian model with persistent supply shocks, that is, sustained increases in production costs due to factors such as wars or geopolitical fragmentation. First, we demonstrate that Taylor rules fail to stabilize long-term inflation due to endogenous...
