We examine how Corporate Social Responsibility (CSR), jointly with influential institutional ownership (IO), affects firm value around the 2008 global financial crisis. We find that the effect of CSR on firm value varies with the level of influential institutional ownership and depends upon economic conditions. Using difference-in-difference methods, we show that compared with non-CSR firms, CSR firms have higher firm values before the financial crisis but experience more loss in firm value during the crisis. Our findings suggest that the overall CSR effect depends on the relative dominance of two effects: conflict-resolution and overinvestment effect. In addition, we apply triple difference analysis and show that the relation between CSR and firm value depends upon the level of influential institutional ownership. Specifically, before the crisis, CSR positively affects the value of low institutional ownership firms and the effect is significantly weaker for firms with higher influential IO. During the crisis, the CSR-firm value relation is positive for high institutional ownership firms, suggesting that overinvestment concerns dominate when the crisis occurs. However, such a positive IO effect is not significant for CSR firms with high rollover risks. Our results are supported by a series of robustness tests.

We examine how firms respond to uncertainty around U.S. tax policy changes, namely the individual level tax rate increases set to take effect on January 1, 2011 and January 1, 2013. We provide evidence that firms time the uncertainty in the tax environment and revise their dividend policy to an expected tax increase. We find that firms are likely to initiate their dividends or intensively increase their existing dividend amount one year before the expected tax increase. In addition, in 2012 when there is much less uncertainty on dividend tax changes than in 2010, firms are less likely to initiate a regular dividend but are more likely to initiate special dividends. The results suggest that firms facing less tax uncertainty are less likely to make long-term commitments on regular dividend payments but are more likely to take advantage of the last-minute low tax benefits by issuing special dividends. Furthermore, the response to the possible elimination of a tax cut was strongest in firms with high levels of tax-affected ownership, supporting the argument that when facing policy uncertainty, firms behave to prepare for the worst scenarios from the viewpoint of the shareholders, which in this case is a tax increase.
