Board Structure and Intragroup Propping: Evidence from Family Business Groups in Hong Kong

Using earnings announcement events made by group member firms in Hong Kong, this study examines the governance role of boards of directors in curbing propping activities within family business groups. We find that earnings released by group member firms affect the stock prices of their nonannouncing group peers in a manner consistent with intragroup propping. More importantly, this effect is less pronounced when the announcing firms have a larger board or a board with a higher proportion of independent directors, but more pronounced when they have an executive director from their controlling families acting as board chairperson. Furthermore, the monitoring effect of boards of directors is strengthened for firms subject to new regulations increasing board power. Our results suggest that board oversight can mitigate propping activities.     

Behaviour of intra-daily stock return on an Asian emerging market - Hong Kong

This study examines the intra-daily return behaviour of one of the most open Asian emerging markets - Hong Kong. It is found that there is a general increase in the positive skewness and kurtosis of all the intra-daily returns after the 1987 October crash and the distributions of all the returns have become non-normal after the crash. There seems to be more day-of-the-week and time-of-the-day variations in the post-crash period than in the pre-crash period. There also exists some day-end effect in both of the periods and such a day-end effect seems to be related to the day of the week.

The value of relational learning in global buyer‐supplier exchanges: a dyadic perspective and test of the pie‐sharing premise

Research in collaborative interorganizational relationships has typically focused on the value of these relationships to a specific supply chain partner. Furthermore, the phenomenon has rarely been explored in a global setting. Using primary data from 126 cross‐border dyads, we investigate the influence of relational learning on the relationship performance of both the buyer and the supplier, testing the contention that both members (1) benefit from relational learning efforts and (2) enjoy equal pieces of the benefits pie. We find that three specific types of relational learning (information sharing, joint sensemaking, and knowledge integration) influence relationship performance, and that these dimensions of relational learning affect supply chain partners in different ways. We draw conclusions regarding the relative value of relational learning for both buyers and suppliers. Copyright © 2011 John Wiley & Sons, Ltd.     

Information disclosure quality: correlation versus precision

We investigate how a multidimensional disclosure quality (i.e., correlation and precision) determines an optimal information disclosure strategy. We find that, for an infinitely lived, unlevered firm with market perfection, a truth‐telling disclosure is optimal at increasing the expected firm value. However, for a finitely lived, levered firm in the presence of market imperfections (e.g., bankruptcy cost), the optimal disclosure quality depends negatively on the level of imperfections. Once we consider the agency problem, such dependence can become positive, thereby highlighting the importance of a proper managerial‐incentive scheme to align the information disclosure interests of managers and shareholders.
