The generic existence of rational expectations equilibrium in the higher dimensional case

The study of the generic existence of rational expectations equilibrium has concentrated on three cases, according to whether the space of “states of private information” has dimension less than, equal to, or greater than the price space. Previous results have shown that in the first case fully revealing equilibria exist generically and in the second case there are open sets of environments with no equilibrium. This paper shows that in the third case there is a residual set of environments which permits equilibria which are arbitrarily close to fully revealing.

Protecting Strategic Knowledge: Insights from Collaborative Agreements in the Aerospace Sector

This paper explores the dilemma that firms face with respect to knowledge sharing in strategic alliances. On the one hand, alliance success is associated with high levels of interaction and co-operation between partners. On the other hand, full and open co-operation exposes a firm's distinctive knowledge and skills and makes it vulnerable to opportunistic moves by alliance partners. Hence firms experience a fundamental paradox: to gain the greatest benefits they must exchange information and knowledge with external parties yet, at the same time, they must protect themselves against knowledge appropriation. This dilemma is particularly acute in the aerospace sector where political imperatives strongly influence partner choice and collaborators are often strong rivals in other contexts. In this paper we use data drawn from four collaborative agreements in the aerospace sector to explore the ways in which a focal firm has sought to protect its strategic knowledge and manage knowledge flows in alliance relationships. We find that existing theoretical lenses provide valuable but partial insights into the question of knowledge appropriation in alliances and offer limited guidance to managers charged with making alliances work. We suggest that some rich insights can be gained by focusing on the overlaps and interstices between existing theories and that greater exploration of the everyday working practices in alliances may offer a useful starting point for improved theorising.     

Manager-analyst conversations in earnings conference calls

Prior research finds that intraday stock prices move considerably during the discussion period of earnings conference calls. In this study, we explore what features of the manager-analyst dialogue during the discussion drive these price movements. We textually analyze the tone of managers and analysts and find that intraday prices react significantly to analyst tone, but not to management tone, for the full duration of the discussion. This effect strengthens when analyst tone is relatively negative. We then present intraday visual evidence that analysts are more neutral than managers over the call and that the tones of both parties drift downward as the call progresses. Overall, our findings illustrate how manager-analyst information exchanges evolve on earnings calls and indicate that analysts are the participants on earnings calls whose comments move stock prices during the discussion.     

Audit Pricing of Shared Leadership

This study explores audit implications of shared leadership in client firms. Analyzing data from 2002 to 2013 of Korean listed companies, we find that auditors spend fewer audit hours and charge lower audit fees for clients with multiple CEOs. Additional tests reveal that the lower audit fees for co-CEO clients are likely attributable to reduced audit effort rather than to reduced hourly rates. We also document that firms with co-CEOs exhibit better-reporting quality than do firms with a solitary CEO. In sum, this article presents evidence that mutual monitoring via co-CEO appointments assures high-quality financial reporting of audit clients, and thus leads to reduced audit fees.     

Owner-managers and firm performance during the asian and global financial crises: evidence from Korea

We examine the performance of the Korean owner-managers during the 1997?1998 Asian financial crisis and the 2008?2009 global financial crisis to establish whether they overcome the unexpected exterior shocks better than employed managers. We find that the owner-managers record a significantly greater performance during the crises, and especially during the latter period. Moreover, our results suggest that such a tendency comes from the owner-managers’ superior investment decisions. Our paper thus highlights the role of owner-managers by studying their performance during the Korean economic crisis periods. (JEL G01, G32, G34)
