This study investigates a communication game between a CEO and a board of directors where the CEO's career concerns can potentially impede value‐increasing informative communication. By adopting a policy of aggressive boards (excessive replacement), shareholders can facilitate communication between the CEO and the board. The results are in contrast to the multitude of models which generally find that management‐friendly boards improve communication, and help to explain empirical results concerning CEO turnover. The results also provide the following novel predictions concerning variation in CEO turnover: (1) there is greater CEO turnover in firms or industries where CEO performance is relatively more difficult to assess; (2) the board is more aggressive in their replacement of the CEO in industries or firms where the board's advisory role is more salient; and (3) there is comparatively less CEO turnover in firms or industries where the variance of CEO talent is high.

We study a dynamic timing game between multiple firms, who decide when to go public in the presence of possible information externalities. A firm's IPO pricing is a function of its privately observed idiosyncratic type and the level of investor sentiment, which follows a stochastic, mean-reverting process. Firms may wish to delay their IPOs in order to observe the market reception of the offerings of their peers. We characterize the unique symmetric threshold equilibrium, whereby pioneer firms with high idiosyncratic types endogenously emerge. The results provide novel implications regarding variation in IPO timing, sequential clustering, IPO droughts, the composition of new issues over time, and how IPO volume fluctuates over time. These include, among others, that in more populated industries, a lower proportion of firms emerge as industry pioneers, but follower IPO volume is intensified. Additionally, heightened uncertainty over investor sentiment exacerbates delay and leads to lower IPO volume.

We study a dynamic voluntary disclosure setting where the manager’s information and the firm’s value evolve over time. The manager is not limited in her disclosure opportunities, but disclosure is costly. The results show that the manager discloses even if this leads to a price decrease in the current period. The manager absorbs this price drop in order to increase her option value of withholding disclosure in the future. That is, by disclosing today, the manager can improve her continuation value. The results provide a number of novel empirical predictions regarding asset prices and disclosure patterns over time. These include, among others, that disclosures are negatively correlated in time, and stock return skewness is negatively correlated with lagged returns for firms with low uncertainty over their future profitability, in more competitive industries, and in industries with less informative public news.
