Accounting Information and Contracting Dynamics

I develop a dynamic principal-agent framework to examine the role of accounting information in a long-term contracting relationship with uncertainty over fundamental performance. Using this model, I characterize the marginal impact of accounting information on intertemporal incentive provision in the face of other sources of information. Cash flows and realizations of an accounting measurement system provide imperfect signals of unobservable firm fundamentals. Accounting information increases the rate at which the principal’s beliefs over fundamentals match those of the agent’s, above and beyond the impact of cash flows, thereby mitigating the difficulty in providing intertemporal incentives that is induced by uncertainty. The belief matching process and the reversal property embedded in the accounting system give rise to an endogenous demand for long-term incentives, and measurement precision directly influences the necessary path-dependence of these incentives over the course of the contractual relationship. Furthermore, equilibrium manipulation of the accounting report becomes increasingly positive as the agency approaches termination. My framework allows for falsifiable empirical predictions regarding the relationship between the properties of accounting measurement and managerial turnover, the evolving nature of incentives over the manager’s tenure, managerial risk-taking activity, and the use of performance-vesting incentives.

Accounting for Compensation: Dynamic Moral Hazard and Optimal Accruals

with Jonathan Bonham

We investigate the impact of accrual accounting policies on contracting and productive efficiency in a continuous-time moral hazard framework. An agent who controls unobservable fundamental performance is compensated via a contract written on cash flows, which contain timing errors, and accounting earnings, which correct timing errors at the expense of introducing estimation errors. Deferred compensation and accruals act as substitutes in solving the incentive problems created by timing errors in cash flows. Accruals are the primary control mechanism late in the agency relationship, when the most efficient accrual policy is time-invariant and standardized—it depends only on the controllability and measurability of fundamental performance as opposed to agency-specific parameters such as risk aversion and discount rates. By contrast, deferred compensation is the primary control mechanism early in the agency relationship, when the most efficient accrual policy changes over time, is non-standardized, and corrects fewer timing errors than the standardized policy.

Uncertainty, Performance Measurement, and the Provision of Dynamic Incentives: Theory and Evidence

In this paper, I examine how the interaction between performance measurement and uncertainty affects the provision of long-term incentives. Guided by a stochastic filtering model where stock prices and earnings provide noisy measures of the same underlying economic construct, unobservable firm fundamentals, I develop a novel empirical measure of intertemporal information asymmetry between the principal and the agent, the rate at which the principal’s beliefs over underlying fundamentals match those of the agent’s. It represents the degree to which stock price and earnings information alleviate the moral hazard problem. This measure helps explain variation in executive pay duration and the use of performance-vesting incentive provisions in long-term compensation contracts. The dynamics of incentives are thus driven primarily by informational concerns, in contrast to the managerial entrenchment view of the executive pay process.

Trade Under Asymmetric Information: A Reader’s Companion

(monograph)
with Thomas Hemmer

There are plenty of good books available that provide summaries and overviews of key contributions of information economics to our understanding of the role of rules and contracts for the functioning of markets. Writing another book of this form makes little sense, and this is not our aim. Rather than providing a substitute for reading the fundamental papers we cover, our goal is to help facilitate the reading of the underlying papers. As such, although entirely feasible, this monograph is not meant to be read as a stand-alone document, but instead read in conjunction with the papers that we cover. The individual notes are structured to help readers through some of the technicalities that, in our experience, stand between readers new to this literature and the important insights that these papers contain. While technically rigorous, we also provide intuition and tie the papers together to help the user better “see the forest for the trees.” Although the monograph spans both classical so-called “Disclosure” and “Contracting” papers, we avoid this segmentation and instead emphasize the commonalities to help readers better explore the links between the individual papers and particular market structures and circumstances.

Accounting Aggregation in Long-Term Incentive Contracts

with Amoray Riggs-Cragun

The construction of accounting-based performance measures entails two primary forms of aggregation. First, the occurrence of like transactions or events are aggregated over time into distinct accounts as dictated by Generally Accepted Accounting Principles (GAAP). Second, accounts are aggregated together in specific ways to construct relevant accounting measures. We develop a fully dynamic principal-agent model which captures both types of aggregation. In our model, a manager controls the intensity of the firm’s revenue and expense accounts, which we model as Poisson processes. These accounts can be aggregated into earnings, which we model as a Skellam process. We study how the second-best levels of revenue-generating effort versus cost-cutting effort evolve over the course of the contracting relationship, as well as how optimal incentives change over time. We also explore conditions under which contracting on aggregated measures may be desirable.

Continuous Measurement with Periodic Reporting: The Economic Effects of Disclosure Frequency

In this paper, I examine the relation between disclosure frequency and the properties of incentives in executive compensation contracts in a setting where periodic financial reports measure unobservable fundamental performance. I develop a continuous-time framework of periodic financial reports that are released at discrete points in time to capture the fact that, while transactions take place continuously, financial statements are only released at predetermined points in time. I explicitly model the financial reporting process as a stochastic jump process where the agent controls the mean jump size at each reporting time. The earnings release times are deterministic at a given frequency level. When financial statements are the only source of information regarding fundamental performance, the optimal compensation contract exhibits jumps for low frequency levels, but gets smoother as disclosure frequency increases. If there is another source of information that is observed continuously, such as cash flows or voluntary disclosures, the contract contains both smooth and discontinuous incentive components.
