Valuation and firm investment and financing policies with personal tax biases

Abstract

In this paper we examine firm financial policies in the presence of personal tax biases (e.g., favoring capital gains relative to interest and dividends). A form of the value additivity principle (VAP) for the tax bias case is established and applied to the firm's merger, investment, financial structure, and dividend decisions. As with the neutral tax VAP, the revised VAP requires transaction costless capital markets but does not require capital market completeness or competitiveness. Share value maximization is found not to be the proper goal for a firm that seeks to maximize the shareholders' current expected utility; however, it is found that share value maximization is generally a good approximate objective. Firm investment policy with financial structure irrelevance (owing to offsetting personal and corporate taxes) is examined assuming that the revised VAP holds.
