We provide a tractable model to study monetary policy under discretion. We restrict our analysis to Markov equilibria. We find that for all parametrizations with an equilibrium inflation rate of about 2 percent, there is a second equilibrium with an inflation rate just above 10 percent. Thus,...

In this paper we investigate dynamics of global inflation and short-run inflation expectations. We estimate a global vector autoregressive (GVAR) model estimated using Bayesian techniques. We then explore the effect of three source of inflationary pressure that could drive up inflation...

This paper seeks to document and explain the effect of a commodity price shock on underlying core inflation, and how that effect changes both across time and across countries. Impulse responses derived from a structural VAR model show that across many countries there was a break in the response...

Recent research in macroeconomics has sought to develop a tractable form of heterogeneity in attempting to model sluggishness of response of the economy consistent with data. Sims (2003) argued that limited information processing was a promising avenue for understanding pervasive stickiness....

The inability of central banks to attain their target inflation rates in recent years has raised questions about the extent to which central banks can control the inflation process. This paper discusses the evolution of thought and evidence since the 1960s on the determinants of inflation and...

This comprehensive study delves into the Harmonised Consumer Price Index (HCPI) behavior across European economies from the early 2000s to the post-pandemic period. By analyzing the patterns of convergence and divergence in HCPI persistence, the study aims to uncover the common external and...

It has been argued that economies with more independent central banks experience lower inflation over time. In this paper we show that this relationship is sensitive to the methodology through which central bank independence indices are constructed. We stress the importance of employing dynamic...

In a simple New Keynesian model, we derive a closed form solution for the inflation-gap persistence parameter as a function of the policy weights in the central bank's Taylor rule. By estimating the time-varying weights that the FED attaches to inflation and the output gap, we show that the...

Beginning with the global financial crisis (2008) the correlation between crude oil prices and medium-term and forward inflation expectations increased leading to fears of their un-anchoring. Using the first principal component of commodity prices as a measure for global aggregate demand, we...
