Abstract

Due to managerial myopia, managers may be reluctant to make long-term investment decisions that do not produce immediate results. Effective corporate governance can align managers’ short-term-oriented incentives with shareholders’ long-term interests. Because the board of directors is the paramount governance mechanism, we explore the role of board governance on managerial myopia. In particular, we investigate the effect of independent directors on corporate innovation. To minimize endogeneity, we exploit the passage of the Sarbanes–Oxley Act as an exogenous shock that raises board independence. Our difference-in-difference estimates show that board independence leads to significantly higher investments in innovation as well as higher innovation productivity. Our results are consequential as they show that board governance has a palpable effect on important corporate outcomes such as innovation productivity.
