What Do Investment Banks Truly Bring to the Table?

摘要

This paper investigates the role of intermediaries in the initial public offering (IPO) process. In the U.S. market, investment banks have traditionally been involved in a firm-commitment or best-efforts underwriting capacity. However, in the Australian IPO market, investment banks are increasingly being named in association with new issues in diverse roles such as issue managers, sponsoring brokers and corporate advisers. Using a sample of 468 IPOs over the 1996 to mid-2006 period, we examine the influence of investment banks across these different engagements. In support of the signalling and information production roles of intermediaries, we find that issuers choosing high intermediary involvement are typically older, retain more capital, seek to raise larger amounts of capital and are without independent expert certification. We find mixed support for the certification hypothesis when testing for the effect of intermediary reputation on IPO issuer wealth loss. Further, the impact of intermediary involvement on underpricing is not significantly different for the different levels of intermediary involvement once issue characteristics have been accounted for. This is puzzling since these different roles by definition do not provide the same level of issue quality assurance.
