Due to its distinctive institutional background, Oman offers a valuable opportunity to examine stock price reactions to dividend announcements. In Oman, (1) there are no taxes on dividends and capital gains, (2) there is a high concentration of share ownership, (3) there is low corporate transparency, and (4) firms frequently change their dividends. Our results show that announcements of dividend increases are associated with increased stock prices, while announcements of dividend decreases cause decreases in stock prices. Firms that do not change their dividends experience insignificant negative returns. These results contradict tax-based signaling models, which argue that higher taxes on dividends relative to capital gains are a necessary condition for dividends to be informative.

We analyse both initial underpricing and post-listing returns for Australian IPOs. Our results are consistent with the view that unique institutional characteristics may have overwhelmed previous Australian tests of equilibrium models of IPO underpricing. The results also show that Australian IPOs significantly underperform market movements in the three-year period subsequent to listing. Further investigation of these anomalous post-listing returns lead us to reject various ‘speculative bubble’ explanations. Rather, the evidence suggests a curvilinear relationship between initial and subsequent returns, although the economic significance of the relationship is low.

This paper examines the value-added role of industry specialist advisors in M&As. We find that compared to non-industry specialists, advisors specializing in the target industry help acquirers garner higher announcement returns. However, there is no significant difference in acquirer returns between advisors specializing in the acquirer industry and non-industry specialists. The choice of a specialist advisor in the target industry benefits acquirers most when there is significant information asymmetry surrounding the targets. Moreover, the bulk of value creation comes from small- to medium-sized financial advisors, rather than large, top-tier investment banks. Finally, our results suggest that advisors specializing in the target industry add value mainly through their ability to help acquirers purchase targets at a lower price.
