This study examines how various aspects of underwriter peer network affect IPOs. We use different network measures to capture underwriter centrality in the global network, cohesion and diversity within network, and prior industry experience of network partners. Our results show that IPOs underwritten by book managers with more central and cohesive networks and partners with previous industry experience are associated with a higher likelihood of an offer price revision and larger price revisions. We also find book managers with more central networks and partners with previous industry experience are associated with higher short-run stock returns, while book managers that maintain more reciprocated peer relationships tend to underprice more. These results indicate that underwriters use peer networks to produce information and place securities, and network structure and characteristics have implications for the quantity and quality of information and the level of cooperative efforts shared among underwriters.

This paper studies the cross-currency and temporal variations in the random walk behavior in exchange rates. We characterize currencies with relatively large investment flows as investment intensive and conjecture that the more investment intensive a currency is, the closer its exchange rate adheres to random walk. Using 29 floating bilateral USD exchange rates, we find that the higher the investment intensity, the less likely it is to reject random walk and the smaller the deviation from random walk is. However, the effect of investment intensity is non-monotonic. Application of threshold models shows that after investment intensity reaches the estimated thresholds, the level of investment intensity has no further effect on the deviation from random walk. These findings help reconcile the previous conflicting results on the random walk in exchange rates by focusing on the effect of cross-currency and temporal variations in investment intensity.
