We use Tobin’s q models of investments to estimate the relationship between corporate governance and the level of innovative activity. Simple ordinary least squares (OLS) models suggest that poor governance reduces innovative activity. However, OLS results are sensitive to controlling for serial correlation, unobserved effects, or using instrumental variables to control simultaneity. Controlling for these effects substantially reduces or eliminates the relationship between governance and innovative activity.

When financial market frictions exist, executives may have to decide which investment activities to reduce when internal funds decrease. Expenditures on research and development (R&D) may be particularly vulnerable because of the long-term nature of innovative activity. We find that equity compensation is associated with lower levels of firm R&D expenditures. Rewarding executives to incur more risk has little effect on R&D expenditures, but rewarding executives for higher returns reduces R&D expenditures and makes R&D expenditures more sensitive to financial market frictions. In contrast, cash compensation reduces the sensitivity of R&D expenditures to financial market frictions.
