The Evolution of Corporate Structure, Internal Governance, and Leadership

My research documents the evolution of the internal governance of senior management in large US firms over a 20-year period and explores, via multiple methods, the causes and consequences of these changes. My findings suggest that firms, in response to increased competition from globalization and reduced costs of information technology, have adopted a structure at the top that is distinct from the traditional, highly-decentralized multidivisional organization documented by Chandler (1962). In large-sample, longitudinal studies of Fortune 500 firms, I show that CEOs have substantially changed the structure and incentives at the top as they shift strategies toward less diversified portfolios. They have “flattened” their firms: they reduced the number of management levels, doubled the size of their executive teams while changing the composition, and substantially increased performance-based pay. To investigate the implications for decision-making, I complement the large-sample research with CEO interviews – what CEOs “say” – and a survey of CEO time use – what CEOs “do.” Taken together, the evidence from multiple methods suggests that large US firms have shifted toward a structure that relies on greater coordination among the top team and a more involved CEO. Another novel insight from this research is that “delayering” at the very top of the pyramid – typically associated with the delegation of authority – is a complex phenomenon that is more indicative of centralization.

Non-Financial Incentives

My research shows how firms combine many facets of internal governance to motivate managers. A perspective that underlies much of my research is that managers are not motivated by financial rewards alone: “it’s not just about the money.” Armed with this perspective, I have investigated compensation design in conjunction with other governance aspects that managers care about. For example, I study perquisites that increase managerial productivity or enhance status (e.g., corporate jets and chauffer services); location decisions that acknowledge social factors (i.e., managerial concern for employee welfare and visibility in the community); the effect of peer comparisons in the setting of executive pay; decision rights or “the right to be the boss” in mergers and acquisitions; the size of divisional investment budgets in internal capital markets; and the position in the organizational hierarchy. Taken together, these papers provide compelling evidence of the importance of non-financial rewards in motivating managers.

Financial Incentives

My research examines how the performance effects of internal governance and the design of compensation vary by managerial position. For example, I document links between innovation and stock options for corporate R&D heads; resource allocation in internal capital markets and the performance measures for division manager bonuses; and earnings management and bonuses for CFOs. Overall, these findings are significant because they demonstrate the complementary nature of internal governance choices, the importance of recognizing non-monetary incentives, and the differential incentive effects across managerial positions.
