Inflation dynamics have been difficult to explain over the last decade. This paper explores if a more comprehensive treatment of globalization can help. CPI inflation has become more synchronized around the world since the 2008 crisis, but core and wage inflation have become less synchronized....

A major challenge for monetary policy has been predicting how exchange rate movements will impact inflation. We propose a new focus: incorporating the underlying shocks that cause exchange rate fluctuations when evaluating how these fluctuations "pass through" into import and consumer prices. We...

This paper uses a ‘trendy' approach to understand UK inflation dynamics. It focuses on the time series to isolate a low-frequency and slow-moving component of inflation (the trend) from deviations around this trend. We find that this slow-moving trend explains a substantial share of UK...

Understanding and forecasting inflation has always been a key focus of macroeconomics and monetary policymaking. Historically, many macroeconomists and central banks have relied on the “Phillips curve� framework for this purpose. Recently, however, the Phillips curve framework has...

The relationship central to most inflation models, between slack and inflation, seems to have weakened. Do we need a new framework? This paper uses three very different approaches - principal components, a Phillips curve model, and trend-cycle decomposition - to show that inflation models should...

This paper finds strong support for a Phillips curve that becomes nonlinear when inflation is "low"--which our baseline model defines as less than 3 percent. The nonlinear curve is steep when output is above potential (slack is negative), but flat when output is below potential (slack is...

This paper revises and extends PIIE Working Paper 20-6. It continues to find strong support for a Phillips curve that becomes nonlinear when inflation is “low”—which our baseline model defines as less than 3 percent. The nonlinear curve is steep when output is above potential (slack is...
