This paper investigates the effects of pre‐IPO banking relationships on a firm's IPO. Using a new and unique data set, which compares the firm's pre‐IPO banking relationships to the underwriters managing the firm's new issue, I test whether banking relationships established before the firm's IPO ameliorate asymmetric informa tion problems behind high IPO underpricing. The results show that firms with a pre‐IPO banking relationship with a prospective underwriter face about 17% lower underpricing than firms without such banking relationships. These results are robust to controlling for the firm's endogenous selection of the pre‐IPO banking institution.

Institutions often own equity in multiple firms that compete in the same product market. Prior research has shown that these institutional “common owners” induce anticompetitive pricing behavior in the airline industry. This paper reevaluates this evidence and shows that the documented positive correlation between common ownership and airline ticket prices stems from the market share component of the common ownership measure, and not the ownership and control components. We further show that the results are sensitive to measures of investor control and to assumptions about equity holders' ownership and control during bankruptcy.
