Do Busy Bees Still Make Honey? Examining the Impact of Non‐CEO Executives’ Outside Roles on Firm Performance

Financial Review, Volume 61, Issue 1, Page 229-260, February 2026.
ABSTRACT We examine how non‐CEO executives (NCEs) serving on outside boards affect their focal firm performance. Firms with such NCEs exhibit lower return on asset (ROA) and profit margins than those without. These effects begin after board service starts, are not explained by busy boards or CEOs, and persist at least a year.

Motivation in All‐Pay Contests

Journal of Public Economic Theory, Volume 28, Issue 1, February 2026.
ABSTRACT This paper studies how agents with monetary and non‐monetary motivation interact strategically in competitions. Examining the question under an all‐pay contest framework, we show that there do not exist pure‐strategy equilibria when the competing agents share the same motivation. When agents with different motivation compete against each other,
