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 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.
