The Myers and Majluf (1984) model predicts a nonpositive price reaction to an announcement of a new issue of equity. This paper shows that the Myers and Majluf result is a direct outcome of their assumption that all potential projects facing the firm have a nonnegative net present value. Refining the Myers and Majluf model, by allowing for the realistic possibility of potential projects having negative net present values, leads to different predictions. The refined model predicts positive as well as negative stock price responses, consistent with recent empirical evidence concerning the stock price effects of new stock issues.

This paper provides a model of how borrowers with private information about their credit prospects choose seniority and maturity of debt. Increased short-term debt leads lenders to liquidate too often. It also increases the sensitivity of financing costs to new information, although better-than-average borrowers desire information sensitivity. The model implies that short-term debt will be senior to long-term debt, and that long-term debt will allow the issue of additional future senior debt. The model also has implications on the structure of leveraged buyouts and on how various types of lenders respond to potential defaults.
