We analyze the duration of bank relationships using a unique panel data set
of listed firms and their banks from the bank-dominated Norwegian market.
We find that firms are more likely to leave a bank as the relationship matu
res. Small, profitable, and highly leveraged firms maintain shorter bank re
lationships, as do firms with multiple bank relationships. These findings a
re robust to censoring, alternate specifications for the distribution of re
lationship duration, and other control variables relevant to the Norwegian
market. Overall., our results cast doubt on theories suggesting that firms
become locked into bank relationships. (C) 2001 Published by Elsevier Scien
