Corporate control and underinvestment

This paper reports a study of how the benefits that large shareholders derive from their control of a firm affect the equity issue and investment decisions of the firm. I introduce an explicit agency cost structure based on the benefits of control of the largest shareholder. In a simple extension of the model developed by Myers and Majluf (J Financial Econ 13:187–221, 1984), I show that underinvestment is aggravated when there are benefits of being in control and these benefits are diluted if equity is issued to finance an investment project. Using a large panel of US data, I find that the concerns of large shareholders about the dilution of ownership and control cause firms to issue less equity and to invest less than would otherwise be the case. I also find that it makes no significant difference whether new shares are issued to old shareholders or new shareholders.
