One hat too many: key executive plurality and shareholder wealth
Article Abstract:
An empirical study is conducted to determine the effects of the announcements of increases in executive plurality on shareholder wealth. The history of the career paths of leading executives of the 1990 Business Week ranking of the 100 most important publicly-held companies is examined to test the hypothesis that the stock market will react unfavorably to the announcement that a company's highest executives have accepted an additional post and have consolidated authority within the firm. The study also tests the assumption that the market will react negatively when the titles of president, CEO and chairman of the board are integrated, than when only two of these titles are consolidated. The findings indicate that the extent of position consolidation is proportional to the level of negativity of shareholder responses.

CEO duality, succession-planning and agency theory: research agenda
Article Abstract:
Harris and Helfat (1998) offer a fresh and unique explanation for the findings of the 1997 study conducted by Worrell et al. Results of this paper show a negative stock market reaction to announcements that a single individual has taken the three executive positions of CEO, Chairman and President. The study found no reaction when an executive in one position is given one other title but found positive reaction when outsiders take two or three titles. According to the researchers, the results provide weak support to agency theory, which posits that directorial boards can more effectively track management performance, thereby improving performance, if major executive posts were divided between two or more people. However, Harris and Helfat contend that these reactions are due to investor concerns about succession planning and executive abilities. However, while plausible, their arguments need to be bolstered by further empirical tests.
