We examine the existence of the investment signaling equilibrium without assuming a specific utility function for the managers of the corporations. We assume the managers have the initial holdings of their own corporations as a form of the executive compensation. Under the different financing schemes to finance the investment, the new equity financing and the risky debt financing, we derive the investment signaling equilibrium and compare the the investment signaling equilibrium under each financing scheme. We show that the investment signaling equilibrium with each financing will obtain with the underinvestment of the high quality firm and that the investment signaling equilibrium with the risky debt financing will dominate the investment signaling equilibrium with the new equity financing.
