In HANK, we show that fiscal policy is an appropriate macroeconomic stabilization tool at the ZLB. Fiscal policy achieves the same macroeconomic aggregates and the same welfare as hypothetically unconstrained monetary policy by replicating its transmission mechanism. Consumption taxes and labor...

We show that in a New Keynesian model with household heterogeneity, fiscal policy can be a perfect substitute for monetary policy: three simple conditions for consumption taxes, labor taxes, and the government debt level are sufficient to induce the same consumption and labor supply of each...

In standard macroeconomic models, the costs of inflation are tightly linked to the price dispersion of identical goods. Therefore, understanding how price dispersion empirically relates to inflation is crucial for welfare analysis. In this paper, I study the relationship between steady-state...

This paper contrasts empirically four leading models of inflation dynamics - the accelerationist Phillips curve (APC), new Keynesian Phillips curve (NKPC), hybrid Phillips curve (HPC) and sticky information Phillips curve (SIPC). We employ an encompassing Phillips curve specification that allows...

A regime shift towards increased inflation expectations is credited with jumpstarting the recovery from the Great Depression in the United States. Germany experienced a recovery as fast and strong in the 1930s. What role did inflation expectations play at the start of this remarkable economic...

This paper aims to explain the causes of rapidly increasing prices in Venezuela and establish whether the current episode can be considered to be of hyperinflationary nature from the post-Keynesian theoretical approach. The chosen approach highlights the role of distributive conflict, indexation...

This paper discusses the likely evolution of U.S. inflation in the near and medium term on the basis of (1) past U.S. experience with very low levels of inflation, (2) the most recent Japanese experience with deflation, and (3) recent U.S. micro evidence on downward nominal wage rigidity. Our...

This paper examines the role of inflation expectations in Solomon Islands, a Pacific Island Country, using the Hybrid New Keynesian Phillips Curve model. The study applies the Generalized Method of Moments to estimate the Hybrid New Keynesian Philips Curve model using quarterly time series data...

Recent survey evidence reveals misaligned inflation expectations among economic agents. While households associate higher expected inflation with lower output growth, professional forecasters often link higher future inflation to stronger economic fundamentals and higher output growth. Firms'...

Central banks in most advanced economies have reacted similarly to the increase in inflation that started in 2021. They initially looked through the rising inflation by leaving monetary policy relatively unchanged. Then, after inflation continued to increase, central banks pivoted by quickly...
