Divestitures and Divisional Investment Policies

We study a sample of diversified firms that alter their organizational structure by divesting a business segment. These firms experience a reduction in the diversification discount after the divestiture. We show that the efficiency of segment investment increases substantially following the divestiture and that this improvement is associated with a decrease in the diversification discount. Our results support the corporate focus and financing hypotheses for corporate divestitures. We demonstrate that inefficient investment is partly responsible for the diversification discount and show that asset sales lead to an improvement in the efficiency of investment for remaining divisions.


Why Do Firms Issue Equity?

Published: 01/11/2007   |   DOI: 10.1111/j.1540-6261.2007.01200.x

We develop and test a new theory of security issuance that is consistent with the puzzling stylized fact that firms issue equity when their stock prices are high. The theory also generates new predictions. Our theory predicts that managers use equity to finance projects when they believe that investors' views about project payoffs are likely to be aligned with theirs, thus maximizing the likelihood of agreement with investors. Otherwise, they use debt. We find strong empirical support for our theory and document its incremental explanatory power over other security‐issuance theories such as market timing and time‐varying adverse selection.
