Abstract One potential real effect of inflation is its influence on the dispersion of relative prices in the economy which affects economic efficiency and aggregate output. Using a novel data set for the US and UK and a VARMA asymmetric bivariate GARCH-M model of inflation and relative price dispersion, we test for the effects of inflation and inflation uncertainty on relative price dispersion.
