We model the impact of public and private ownership structures on firms' incentives to invest in innovative projects. We show that it is optimal to go public when exploiting existing ideas and optimal to go private when exploring new ideas. This result derives from the fact that private firms are less transparent to outside investors than are public firms. In private firms, insiders can time the market by choosing an early exit strategy if they receive bad news. This option makes insiders more tolerant of failures and thus more inclined to invest in innovative projects. In contrast, the prices of publicly traded securities react quickly to good news, providing insiders with incentives to choose conventional projects and cash in early.

Executives can only impact firm outcomes if they have influence over crucial decisions. On the basis of this idea, we develop and test the hypothesis that firms whose CEOs have more decision-making power should experience more variability in performance. Focusing primarily on the power the CEO has over the board and other top executives as a consequence of his formal position and titles, status as a founder, and status as the board's sole insider, we find that stock returns are more variable for firms run by powerful CEOs. Our findings suggest that the interaction between executive characteristics and organizational variables has important consequences for firm performance.

We develop a theory of blockchain governance. In our model, the proof-of-work system, the most common set of rules for validating transactions in blockchains, creates an industrial ecosystem with specialized suppliers of goods and services. We analyze the interactions between blockchain governance and the market structure of the industries in the blockchain ecosystem. We show that the proof-of-work system may lead to a situation in which some large firms in the blockchain industrial ecosystem—blockchain conglomerates—capture the governance of the blockchain.
