The adoption of outside boards by small private US firms

Abstract
The research issue motivating the present study is concerned with why some small private firms adopt an ‘outside board’ (i.e. larger boards in which the majority of directors are neither managers of the firm nor relatives of the Chief Executive Officer (CEO)) and others do not. This issue is addressed by investigating whether differing contextual conditions distinguish adopters from non-adopters of outside boards. The authors consider the adoption of an outside board to be one part of a larger organizational life-cycle process in which organizations implement more ‘professional management’ structures and practices in response to their evolving internal and external contexts. The authors examine simultaneously three contextual pressures that commonly confront small private firms as they develop over time- firm growth and larger size, the succession of the CEO, and the diffusion of equity to individuals outside the firm- to determine which of these are salient in explaining the presence of an outside board. Logistic regression results (3070 respondents toa cross-industry mail survey) indicate that outside boards are more likely when more equity is held by individuals outside the firm, CEOs are older and CEOs do not intend to implement an intra-family transition of leadership. The results suggest that firms adopt outside boards primarily to satisfy the desires of external owners, and only secondarily for the service and resource benefits that outside directors provide.
