Abstract

We document the existence of expertise rents by finding that financial experts on audit committees obtain higher abnormal returns from insider purchases than do non‐financial experts on audit committees. We further investigate whether information processing skills work alone or jointly with an information advantage to generate expertise rents. While financial experts on audit committees outperform financial experts on other committees, financial experts on compensation, executive, nominating, and governance committees do not outperform non‐financial experts on these committees. These findings suggest that expertise rents are domain‐specific and can be obtained only when directors have both access to private information and information processing skills. In additional testing, we find that expertise rents for financial experts on audit committees are primarily driven by non‐accounting financial experts, whose finance or supervisory experience could make them better than accounting financial experts in understanding market conditions and assessing firm risk. Les auteurs documentent l'existence de rentes d'expertise en constatant que les membres de comités d'audit qui sont des experts financiers tirent des achats d'initiés des rendements anormaux supérieurs à ceux qu'obtiennent les membres des comités d'audit qui ne sont pas des experts financiers. Poussant plus loin leur analyse, ils se demandent si les compétences dans le traitement de l'information ont sur la génération de rentes d'expertise une incidence propre, ou une incidence conjuguée à celle d'un avantage au chapitre de l'information. Bien que les experts financiers membres de comités d'audit affichent une performance supérieure à celle des experts financiers appartenant à d'autres comités, la performance des experts financiers membres des comités de rémunération, de direction, de mises en candidature et de gouvernance n'est pas supérieure à celle des membres de ces comités qui ne sont pas des experts financiers. Ces constatations semblent indiquer que les rentes d'expertise sont particulières au domaine et ne peuvent être obtenues que lorsque les dirigeants bénéficient à la fois d'un accès à de l'information privilégiée et de compétences dans le traitement de l'information. Les résultats de tests supplémentaires effectués par les auteurs indiquent que les rentes d'expertise, dans le cas des experts financiers membres de comités d'audit, sont principalement le fait d'experts financiers ne possédant pas de compétences en comptabilité, dont l'expérience en finance ou en supervision pourrait expliquer leur supériorité sur les experts financiers dotés de compétences en comptabilité dans la compréhension des conditions du marché et l'évaluation du risque auquel est exposée l'entreprise.
