This paper explores the effects of mergers on the investment incentives of the levered firm and on levered firm value. Under a fairly broad set of assumptions, it is shown that most firm combinations “improve” investment incentives, bringing about a reduction in the agency costs of underinvestment associated with risky debt. The effect of the merger on debt and equity claim values is also explored. If not properly anticipated, the merger may create a wealth transfer from equity holders to bondholders. Such a wealth transfer includes, but is not limited to, the “coinsurance effect.”

In an experimental setting when outcomes are stochastically related to actions, predictions of equilibrium behavior depend not only on the participants' preference orderings of outcomes, but also on their orderings of lotteries on outcomes as well. We introduce and test a reward structure that can be utilized in any experimental setting to allow the experimenter to decree beforehand the subjects' preferences for lotteries on experimental outcomes. We show analytically that the proposed reward structure can induce subjects to behave as if they have the decreed preference function defined on experimental outcomes. Empirical tests using two different choice settings provide evidence to support this ability to control preferences.
