Appointments of academic directors

- Demonstrates importance of heterogeneity in the director selection process
- Examines factors influencing academic director appointments and market reactions
- Specialized professors are appointed for expertise and are valued by the market.
- Administrative academics are appointed for networks but the market reaction varies.
- Business professors are appointed for prestige with no significant reaction.

We examine the outside director selection process using unique data on appointments of academic directors. Overall, we find that academic directors tend to be appointed by small- and mid-cap firms expanding their boards. However, we find important differences in both the factors influencing academic appointments and the market's reaction when allowing for firm, board, and director heterogeneities. Academics in science, medicine and engineering appear to be appointed for their expertise, and the market reacts favorably. Academic administrators appear to be appointed for their networks, and the market reacts favorably when the administrator is affiliated with a business school but negatively when the administrator is not within close geographic proximity. Business professors appear to be appointed for general expertise and reputation, but we find little evidence of any significant market reaction. The results in this paper highlight the importance of recognizing heterogeneity in understanding the director selection process and the role of outside directors.
