Summary
We investigate whether the size of operational risk losses can be correlated with geographical
region and ¯rm size. We extend past studies of losses on ¯rm size by applying quantile
regression techniques to obtain a more complete view of scaling relationships across the
loss distribution. Furthermore, we test whether these distributional scaling relations can be
described using simple location-shift or location-scale shift models. In addition, we develop a
novel \quantile matching" algorithm to address statistical issues that arise when estimating
loss scaling models when the data are subjected to a loss reporting threshol
