Institutions or individuals form connections with each other in different ways for different purposes. Networks, broadly understood as a collection of nodes and connections between nodes, can therefore be a useful representation of financial systems. Using social network analysis (SNA), this thesis provides novel empirical evidence on the effects of network centrality, which refers to an actor’s position and level of connectedness in a network, on Australian initial public offering (IPO) firms that went public between 2001 and 2017. The thesis includes three essays that aim to examine: (1) the relationship between investment bank networks and the accuracy of IPO prospectus earnings forecasts, (2) the overinvestment problem associated with excess cash in seasoned versus newly public firms, and whether investment bank networks affect the performance of IPO firms with excess cash, and lastly, (3) the relationships between board networks, cash holdings, and IPO firms’ performance. The first empirical essay investigates whether investment banks with more central network positions could improve earnings forecast accuracy in the context of Australian IPOs issued during the 2001-2017 period. Using SNA to construct investment bank network centrality, I show that IPOs backed by more central investment banks tend to have higher absolute offer price revision, exhibit greater forecast accuracy, and are associated with more pessimistic forecasts. Taken together, the results support the idea that, relative to their counterparts that are peripheral in the network, more central investment banks may produce more information in the IPO process and certify the quality of IPO issuers by encouraging more conservative and accurate earnings forecasts. This study makes an important contribution by adding to the burgeoning literature on network studies in the context of IPO investment banking. To the best of my knowledge, this study is the
