Private equity funds implement various management and governance practices in firms they endorse, signaling higher quality of sponsored IPOs (Initial Public Offer). However, the participation of such PE funds comes at a cost for newcomer firms, as they may lose both autonomy and future post-IPO earnings. If they do not choose to signal quality through PE funds, the IPO literature points to the validity of other mechanisms, such as the experience and centrality of the board of directors. We theorize and test the effect of the tradeoff between private equity sponsorship and board centrality and experience on IPO performance. We analyzed the effects of signaling on long-term performance through the one-year cumulative abnormal return in Brazilian IPOs issued between 2004 and 2013. Our results indicate that private equity sponsorship is the most effective signal, completely overtaking the relevance of board centrality and experience to explain IPO performance. However, these latter board characteristics significantly affected the performance of non-private equity-backed IPOs. Between PE-backed companies, there is a reverse effect of the board centrality on the IPO's performance and a substitution effect of the board's previous experience with IPO processes.

To overcome liabilities of foreignness and outsidership during internationalization, board interlock is an effective conduit of foreign knowledge inflows and organizational learning that firms require. We focus on the time dimension of such influence and hypothesize that the tenure of board interlocks with firms with experience in outward foreign direct investment (OFDI) in a country promotes the OFDI decision of the focal firm to that particular country. However, such an effect diminishes as the tenure of interlock ties increases. Moreover, as an alternative knowledge source, OFDI knowledge from the focal firm's neighboring region may weaken the baseline effect. Based on longitudinal data of listed firms in China, our empirical results support the hypotheses. This study enriches the literature on social network learning by identifying its temporal nature and the substitution between different knowledge sources. It also demonstrates the importance of rotating a firm's board members, so that knowledge acquisition and learning remain fresh.
