Short Bio

    I am an applied microeconomic theorist with a focus on organizational economics and industrial organization. At a broad level, my research studies how incentives—predominately financial ones—affect the behaviors of individuals and organizations. One line of research studies how firms can design effective incentive schemes to motivate their employees. Another line analyzes public good provision problems, and specifically, how inefficiencies such as freeriding can be attenuated.
     
    At Kellogg, I teach Strategy and Organizations (STRT 452), an elective MBA course on organizational economics, which offers a microeconomic approach to both the internal organization of firms and its relationship with their rivals' overall strategies. Topics include incentive pay, decentralization (e.g., transfer pricing and coordination issues), horizontal mergers, and vertical integration.


Working Papers / Work in Progress

  • Contracting with Moral Hazard: A Review of Theory & Empirics  (August, 2022)
    To appear in the Elgar Encyclopedia on the Economics of Competition and Regulation (ed. Michael Noel)

    Abstract: This article surveys the literature on principal-agent problems with moral hazard that gained popularity following the seminal works of Mirrlees (1976), Holmstrom (1979), and others. This literature is concerned with designing incentives to motivate one or more workers—typically by paying for performance—in settings where his actions cannot be directly contracted on. I begin with the canonical framework, and then in Section 2, I categorize the subsequent literature that relaxes various assumptions of this framework. Section 3 focuses on the empirical research, and Section 4 discusses other strands of the literature. My goal is to provide a broad and concise overview-sometimes at the expense of depth, and focus on the economic insights (rather than methodological contributions).

  • Flexible Moral Hazard Problems  [Slides]  (December, 2023)
    with Doron Ravid and Balazs Szentes
    Econometrica, Forthcoming

    Abstract: This paper considers a moral hazard problem where the agent can choose any output distribution with a support in a given compact set. The agent's effort-cost is smooth and increasing in first-order stochastic dominance. To analyze this model, we develop a generalized notion of the first-order approach applicable to optimization problems over measures. We demonstrate that each output distribution can be implemented and characterize those contracts which implement that distribution. Contracts are shown to satisfy a simple first-order condition which equates the agent's marginal cost of changing the implemented distribution locally with its marginal benefit. Furthermore, the agent's wage turns out to be increasing in output. Finally, we consider the problem of a profit-maximizing principal and provide a first-order characterization of principal-optimal distributions.

  • Robust Contracts: A Revealed Preference Approach  [Slides]  [EC'23]  (June, 2023)
    with Nemanja Antic

    Abstract: We study an agency model in which the principal has outcome data under different incentive schemes and aims to design an optimal contract under minimal assumptions about the way the agent responds to incentives. In particular, the principal knows the agent-optimal actions, which are distributions over outcomes, in response to K "known" contracts but is unaware of other actions available, and importantly, of their costs. The principal seeks a contract that maximizes worst-case profits. The optimal contract is a mixture of the known contracts and the (linear) one that makes the agent residual claimant. Moreover, when K=1, the single known contract maximizes the principal's profit guarantee, whereas, with two known contracts, the optimal mixture puts strictly positive weight on one of the known contracts. Our methodology is straightforward to implement, a point that we demonstrate using data from the DellaVigna and Pope (2018) experimental study of different incentive schemes.

  • Feedback Design in Dynamic Moral Hazard  [Slides]  (February, 2024)
    with Jeffrey Ely and Luis Rayo
    Econometrica, Revise & Resubmit

    Abstract: We study the joint design of dynamic incentives and performance feedback for an environment with a coarse (all-or-nothing) measure of performance, and show that hiding information from the agent can be an optimal way to motivate effort. Using a novel approach to incentive compatibility, we derive a two-phase solution that begins with a "silent phase" where the agent is given no feedback and is asked to work non-stop, and ends with a "full-transparency phase" where the agent stops working as soon as a performance threshold is met. Hiding information leads to greater effort, but an ignorant agent is also more expensive to motivate. The two-phase solution—where the agent's ignorance is fully frontloaded—stems from a "backward compounding effect" that raises the cost of hiding information as time passes.
