Endogeneity and the relationship between board structure and firm performance: a simultaneous equation analysis for the Athens Stock Exchange

Abstract

The main goal of this paper is to examine the relationship between the three most important characteristics of the board of directors with firm performance. More specifically, we investigate whether the independence of the board, the leadership structure and the board size, are exogenous determinants to the firm's performance, using a simultaneous equations framework. Our database is composed of firms quoted in the ASE, starting from 146 observations in 2000 and ending with 232 firms in 2006. The findings suggest that the board independence and the leadership structure do not affect the firm performance. On the other hand, an inverse relationship between board size and firm performance is observed. Copyright © 2010 John Wiley & Sons, Ltd.

Influence of board of directors on firm performance: Analysis of family and non-family firms

“…While some studies found a negative correlation between these variables (Agrawal and Knoeber, 1996;Bhagat and Black, 1999), others supported the idea of a positive correlation between the variables (Rosenstein and Wyatt, 1990;Dahya and McConnell, 2007). However, many studies also suggested that board independence has no statistically significant effect on the firm's financial performance (Hermalin and Weisbach, 1991;Drakos and Bekiris, 2010). Johnson et al (1996) concluded that relationships between board independence and performance might not exist.…”

“…On the other hand, numerous researchers favour smaller boards and are of the view that large boards lead to non-cooperation and waste of time in decision making as they suffer from social loafing. Thus, their knowledge and skills remain unutilized (Dharmadasa et al, 2014;Drakos, & Bekiris, 2010;Jensen, 1993;Lin, 2011).…”

“…This approach also assists us in addressing issues of endogeneity in relation to board appointments and performance (Hermalin and Weisbach (2003) and Drakos and Bekiris (2010)). For example, as specified, NXXDs positively affect the appointing firm's performance.…”
