Optimal Managerial Authority  (New version!)  (Under Review)

Abstract: This paper formulates a dynamic agency framework to explore optimal managerial authority and compensation over a manager's career in a firm: Initially, authority is assigned independently of the manager's outside options or recruitment costs, unlike compensation, which increases in both. Over time, managerial authority and compensation rise after good performance and decline otherwise.  Authority-performance sensitivity decreases with increased authority — reflecting rational entrenchment — while pay-performance sensitivity grows. Moreover, costly authority adjustment causes inefficient self-dealing, and early-career luck followed by late-career misfortune can lead to massive self-dealing; this analysis underscores early-career luck's disproportionate impact on a manager's authority and lifetime utility.

Platform Enterprises: Financing, Investment, and Network Growth   

Abstract: I develop a tractable micro-founded dynamic platform model featuring cross-group network effects. Networks are analogous to capital assets, and the platform enterprise invests in the networks by making subsidies to users. The paper characterizes the entrepreneur's optimal financing and investment strategies. The main findings are: 1) making highly aggressive subsidies by using up available funds is optimal; 2) per-transaction subsidies decrease as the network grows; 3) the platform with stronger network effects has a propensity to make more subsidies at initial stages; 4) staged financing mitigates the limited enforcement problem, and ceteris paribus, the number of funding rounds decreases with the profitability of the platform and increases with required profits by financiers; 5) the value of funds raised each round increases and the financing frequency decreases over time.

Corporate Governance Time Bombs, with Martin Oehmke  

Why are “corporate time bombs’’ (festering problems that can lead to extreme losses for a firm) often kept unsolved? We show that, if the manager’s tenure is uncertain, it can be optimal to provide only low-powered incentives to defuse corporate time bombs, so that procrastination is a rational response. If the problem remains unsolved after the incumbent manager’s departure, incentives given to successive managers to defuse the time bomb are even lower, due to the principal’s belief updating. The model implies that time bombs have to be defused within a certain time frame and shows that frequent managerial turnover leads to missed opportunities for solving the problem.
