Using a novel dataset of firm product introductions, we examine whether public short campaigns (PSCs) have real impacts on targets. Targets introduce fewer new products and experience declines in productivity and product quality relative to matched firms following PSCs. These declines in product outcomes are partly attributed to the withdrawal of support from key stakeholders, resulting in reduced access to external capital, decreased employee commitment, and weakened customer relationships. Our results suggest that the public nature of PSCs has distinctive impacts on target firms compared to traditional short selling, primarily through their impact on the firm's stakeholders.

We provide empirical evidence on the positive effect of non-executive employee stock options on corporate innovation. The positive effect is more pronounced when employees are more important for innovation, when free-riding among employees is weaker, when options are granted broadly to most employees, when the average expiration period of options is longer, and when employee stock ownership is lower. Further analysis reveals that employee stock options foster innovation mainly through the risk-taking incentive, rather than the performance-based incentive created by stock options.

We examine how real investment decisions of firms are affected by their CEOs' career concerns. Relative to their older counterparts, younger CEOs are more likely to enter new lines of businesses and exit from existing ones. Younger CEOs undertake bolder expansions and divestments, which lead to significant increases and decreases in firm size, respectively. Younger CEOs also prefer to grow through acquisitions than de novo investments. However, such busier investment style of the younger CEOs appears not to hurt firm efficiency. Additional results also shed light on how CEO favoritism distorts capital allocation within firms.

Companies actively seek to appoint outside CEOs to their boards. Consistent with our matching theory of outside CEO board appointments, we show that such appointments have a certification benefit for the appointing firm. CEOs are more likely to join boards of large established firms that are geographically close, pursue similar financial and investment policies, and have comparable governance to their own firms. The first outside CEO director appointment has a higher stock-price reaction than the appointment of another outside director. Except for a decrease in operating performance following the appointment of an interlocked director, CEO directors do not affect the appointing firm's operating performance, decision-making, and CEO compensation.

Following surprise independent director departures, affected firms have worse stock and operating performance, are more likely to restate earnings, face shareholder litigation, suffer from an extreme negative return event, and make worse mergers and acquisitions. The announcement returns to surprise director departures are negative, suggesting that the market infers bad news from surprise departures. We use exogenous variation in independent director departures triggered by director deaths to test whether surprise independent director departures cause these negative outcomes or whether an anticipation of negative outcomes is responsible for the surprise director departure. Our evidence is more consistent with the latter. Received January 12, 2016; editorial decision October 7, 2016 by Editor David Denis.

We examine the value impact of independent directors nominated by activists (Activist IDs). Firms appointing Activist IDs experience larger value increases than firms appointing other directors, particularly when Activist IDs have private firm experience and when their nominators remain as shareholders. This value increase persists over a long period and is greater than that of activism events without director appointments. The increase is also higher among firms with greater monitoring needs and entrenched boards. Moreover, the appointments of Activist IDs are greeted more positively by the market, and Activist IDs obtain more favorable shareholder votes and additional future directorships.
