While the degree of policy inertia in central banks' reaction functions is a central ingredient in theoretical and empirical monetary economics, the source of the observed policy inertia in the U.S. is controversial, with tests of competing hypotheses such as interest-smoothing and...

With positive trend inflation, the Taylor principle is not enough to guarantee a determinate equilibrium. We provide new theoretical results on restoring determinacy in New Keynesian models with positive trend inflation and combine these with new empirical findings on the Federal Reserve's...

We consider a DSGE model in which firms follow one of four price-setting regimes: sticky prices, sticky-information, rule-of-thumb, or full-information flexible prices. The parameters of the model, including the fractions of each type of firm, are estimated by matching the moments of the...

We assess whether central banks may use inflation expectations as a policy tool for stabilization purposes. We review recent work on how expectations of agents are formed and how they affect their economic decisions. Empirical evidence suggests that inflation expectations of households and firms...

Using a large-scale survey of U.S. households during the Covid-19 pandemic, we study how new information about fiscal and monetary policy responses to the crisis affects households' expectations. We provide random subsets of participants in the Nielsen Homescan panel with different combinations...

We provide a comprehensive assessment of five monetary policy regimes-inflation targeting (IT), dual mandate (DM), average inflation targeting under 4-period (AIT-4) and 10-period (AIT-10) horizons, price level targeting (PLT), and nominal GDP level targeting (NGDP)-in a unified experimental...

Elevated inflation can threaten the credibility of central banks and increase the risk that inflation expectations do not remain anchored. Wage-price spirals might develop in such an environment, and high inflation could become entrenched. We quantitively assess the risks of a wage-price spiral...
