THE ROLE OF THE PAYBACK PERIOD IN THE THEORY AND APPLICATION OF DURATION TO CAPITAL BUDGETING

The payback period has been a widely used capital budgeting tool in the analysis of capital projects. It has come under criticism for its inablility to consider all the project's flows in a present valued context. The purpose of this article is to present the duration measure in a capital budgeting framework and show how it is related to the payback period. The relationship is shown analytically and empirically. As a result, the payback period assumes a new identity which goes far to overcome the objections historically levied against it.
