Corporate Governance Objectives of Labor Union Shareholders

The SEC has been considering the issue of increased shareholder access to the corporate proxy and director elections. Labor union pension funds have been among the more vocal proponents of increased access, arguing that such access will lead to improved financial performance. Business groups, such as the Business Roundtable, have argued against increased access on the grounds that such access would encourage special-interest shareholders and would decrease shareholder value. The desirability of increased shareholder access, then, depends to a large degree on the extent to which labor unions (and other politically minded shareholders) pursue the interests of shareholder value rather than their own self-interest.

One of our Ph. D. students, Ashwini Agrawal, has written one of the first papers that addresses this issue. Ashwini noticed that in 2005, the AFL-CIO (the central federation of labor unions in the U.S.) split into two groups. Several of its member unions, representing roughly 35% of its members, left to form a new organization–the Change To Win (CTW) coalition. This exogenous shift in AFL-CIO membership allows Ashwini to examine changes in the voting behavior of AFL-CIO affiliated shareholders toward management and director nominees.

The results are striking. Ashwini finds that AFL-CIO affiliated pension funds are significantly more supportive of director nominees once the AFL-CIO no longer represents workers at a given firm (roughly 74% after versus 55% before). At the same time, AFL-CIO affiliated pension funds do not change their voting behavior when the AFL-CIO still represents workers at a given firm. Ashwini finds the opposite pattern in voting behavior for a pension fund associated with the CTW coalition. Finally, he finds no change in voting behavior for mutual funds.

These differences suggest that labor unions use their pension funds to pursue labor relations issues at the expense of shareholder value. And they suggest that there is some truth to the concerns that increased shareholder access might have unintended consequences.
