Inflation, relative price variability and the markup: evidence from the United States and the United Kingdom
Title: Inflation, relative price variability and the markup: evidence from the United States and the United Kingdom
Citation: Economic Modelling, 2007, 24, 82-100
This paper links two separate empirical literatures on inflation, relative price variability (RPV) and the price–cost markup. Measures constructed from annual and quarterly data for the US and UK are used to examine the nature of the relationships among these variables. The results show that two long-run relationships can be identified from the data: a negative relationship between inflation and the markup and a positive relationship between inflation and RPV. We eliminate the possibility that inflation is a proxy for RPV in the inflation–markup relationship and show systems estimates to be superior to single-equation estimates.
