In this paper we estimate the rate of exchange rate pass-through (ERPT) into UK import prices using disaggregate data at the SITC-2 and SITC-3 digit level. Consistent with earlier studies, we find evidence for significant heterogeneity among the estimated industry-specific pass-through rates. In an environment where cross-sectional heterogeneity is significant the use of aggregate data can be misleading since aggregation may lead to heavily biased ERPT estimates at the economy-wide level. We demonstrate that the aggregation bias caused by this heterogeneity is not negligible for the UK data. Further, we investigate the source of the cross-sectional variation in the estimated industry-specific pass-through rates. For our sample, we find the industry-specific average inflation rates to be significant in explaining this variation. Furthermore, we find evidence for short-run and long-run partial pass-through into food and manufacturing sectors. As for the economy-wide ERPT the conclusion stands, possibly reflecting the relatively large weight of manufacturing goods in UK imports. Finally, we find a significant reduction in estimated ERPT rates since 1995 caused by increased stability of the UK economy over the past decade.
