Abstract: This paper studies price dispersion in the Norwegian retail market for 766 products across 4297 stores over 60 months. Price dispersion for homogeneous products is significant and persistent, with a coefficient of variation of 37% for the median product. Price dispersion differs between product categories and over time. Store heterogeneity accounts for 30% of the observed variation in prices for the median product-month and for around 50% for the sample as a whole. Price dispersion is still prevalent after correcting for store heterogeneity.
