Common ownership, competition, and top management incentives

An interesting looking revised version of a working paper from the Cowles Foundation for Research in Economics at Yale University on "Common Ownership, Competition, and Top Management Incentives" (pdf). The paper is by Miguel Antón, Florian Ederer, Mireia Giné, and Martin Schmalz.

The abstract reads:

We show theoretically and empirically that managers have steeper financial incentives to expend effort and reduce costs when an industry’s firms tend to be controlled by shareholders with concentrated stakes in the firm, and relatively few holdings in competitors. A side effect of steep incentives is more aggressive competition. These findings inform a debate about the objective function of the firm.

The basic conclusion of the paper is,

We found that the sensitivity between top managers’ wealth and their firm’s performance is weaker when the firms’ largest shareholders are also large shareholders of competitors. The wealth-performance relation for managers is steeper when firms are owned by shareholders without significant stakes in competitors.

Thus you will get more competition when a firm is owned by shareholders without significant stakes in competitors.
