Abstract
For their study, Ongena and Smith (1999b) collect annual information on the identity of bank relationships maintained by non-financial firms listed on the OSE between 1979 and 1995.12 Their sample covers, on average, 95% of all firms listed on the OSE during that period. Although these firms represented less than 0.10% of the total number of incorporated companies in Norway, their total market value in 1995 equaled 45% of Norway's GNP.
