Abstract
This paper studies the effect of bank relationships on underwriter choice in the U.S. corporate‐bond underwriting market following the 1989 commercial‐bank entry. I find that bank relationships have positive and significant effects on a firm's underwriter choice,over and abovetheir effects on fees. This result is sharply stronger for junk‐bond issuers and first‐time issuers. I also find that there is a significant fee discount when there are relationships between firms and commercial banks. Finally, I find that serving as arranger of past loan transactions has the strongest effect on underwriter choice, whereas serving merely as participant has no effect.
