Interest rate swaps, a financial innovation in recent years, are based upon the principle of comparative advantage. An interest rate swap is a useful tool for active liability management and for hedging against interest rate risk. The purpose of this paper is to provide a simple economic analysis of interest rate swaps. Alternative uses of and the appropriate valuation procedure for interest rate swaps are described.

Capital market data were used to examine the divestiture effects pertaining to deregulation, the dropping of antitrust charges, and the reversing of the co‐insurance effect associated with the recent breakup of AT&T. The empirical results of the study indicate that significant economic events took place during the breakup process, which led to transfers of wealth from various parties to the securityholders of AT&T. The results also indicate that the buffering effect of regulation was reduced as AT&T went through the total deregulation process. This is in accordance with Peltzman's prediction.

The ownership of pension assets in a defined benefit pension plan is an unresolved issue in corporate finance. The issue is important because it defines the appropriate investment policy for a pension fund. In this paper, we summarize the ownership debate in the form of two mutually exclusive theories. We then focus on a recently popular event in pension finance, excess asset reversions. Our paper demonstrates the valuation effects associated with this event in a stochastic dominance framework. Under certain conditions, a reversion constitutes an expropriation of wealth from the participants and beneficiaries of the plan to the firm. Using data provided by the Pension Benefit Guaranty Corporation and the Center for Research in Security Prices tape, we examine the returns to the shareholders of 58 companies which conducted excess asset reversions between 1980 and 1984. Our results show that large abnormal returns accrued to these shareholders around the time of the reversion. These findings have implications both for the appropriate investment policy of pension funds and for public policy with respect to plan terminations.
