(1) Divide and Inform: Rationing Information to Facilitate Persuasion. 2017. The Accounting Review, Vol 92 (5)
featured in “Do fair disclosure rules lead to more or less information?" by Michael Totty, UCLA Anderson Review, May 16, 2018

This article develops a Bayesian persuasion model examining a manager’s incentives to gather information when the manager can disseminate this information selectively to interested parties (“users”) and when the objectives of the manager and the users are not perfectly aligned. The  model predicts that, if the manager can choose the subset of users to receive the information, then the manager may gather more precise information. The article identifies conditions under which a regime that allows managers to grant access to information selectively maximizes aggregate information. Strikingly, this happens when the objectives of managers and users are sufficiently misaligned. This finding is robust to variations of the model such as information acquisition cost, unobservable precision, sequential noisy actions taken by the users and delayed choice of the subset of users in “the know.” These results call into doubt the common belief that forcing managers to provide unrestricted access to information to all potential users is always beneficial.

(2) Investments and Risk Transfers. With Tim Baldenius. 2017. The Accounting Review, Vol 92 (6)

We demonstrate a novel link between relationship-specific investments and risk in a setting where division managers operate under moral hazard and collaborate on joint projects. Specific investments increase efficiency at the margin. This expands the scale of operations and thereby adds to the compensation risk borne by the managers. Accounting for this investment/risk link overturns key findings from prior incomplete contracting studies. We find that, if the investing manager has full bargaining power vis-a-vis the other manager, he will underinvest relative to the benchmark of contractible investments; with equal bargaining power, however, he may overinvest. The reason is that the investing manager internalizes only his own share of the investment induced risk premium (we label this a "risk transfer"), whereas the principal internalizes both managers' incremental risk premia. We show that high pay-performance sensitivity (PPS) reduces the managers' incentives to invest in relationship-specific assets. The optimal PPS thus trades off investment and effort incentives.

(3) Optimal Reporting When Additional Information Might Arrive. With Henry Friedman and John Hughes. Journal of Accounting and Economics, forthcoming

We study how the potential for discretionary disclosure affects the way a firm designs its reporting system. In our model, the firm's primary but nonexclusive concern is to induce beliefs that exceed a threshold. Such thresholds arise in numerous contexts, including investing decisions, liquidation/continuation choices, covenants, audits, impairments, listing requirements, index inclusion, credit ratings, analyst recommendations, and stress tests. The optimal reporting system is characterized by informative good reports when the threshold is high and, potentially, uninformative reports when the threshold is low. Under an optimal impairment-type reporting system, the likelihood of reported impairments and the information content of non-impairment reports both increase in the probability of the firm observing private information. We provide a novel motivation for the quiet period around an IPO and empirical predictions relating the probability of discretionary disclosure to the properties of financial reports. In extensions, we consider disclosure mandates, report manipulation, endogenous thresholds, and alternative payoff functions.

(4) Integrated Ownership and Managerial Incentives with Endogenous Project Risk. With Tim Baldenius. Review of Accounting Studies, forthcoming

Integrated ownership is often seen as a way to foster specific investments. However, even in integrated firms, managers invest to maximize their compensation which is chiefly driven by divisional income. Thus it is not clear that integration has any effect on investments in a world of decentralized decision-making. Building on recent findings that efficiency-enhancing investments raise not only the expected value of a project but also its variance, we show that under plausible conditions integration calls for low-powered incentive contracts: the managers invest more as they are less exposed to the investment-related (endogenous) risk, and the principal of an integrated firm has more to gain from greater investment. On the other hand, integration may result in higher-powered incentives if the project is inherently very risky or if the project-specific input is personally costly to the managers (rather than a monetary investment). The qualitative takeaway remains, however, that the contract adjustments under integration mitigate any input distortions present under non-integration. We also allow for firmwide performance evaluation under integration and show that it may lead to larger input distortions, but those are outweighed by improved risk sharing.

(5) Responsibility Centers, Decision Rights, and Synergies. With Tim Baldenius. The Accounting Review, forthcoming

We consider the optimal allocation of decision rights in an incomplete contracting setting where business unit managers choose inputs that enhance the efficiency of "joint projects" (projects that benefit their own and other divisions). With scalable project inputs, decision rights should be bundled in the hands of one division manager. Which of the managers to designate the investment center manager-the one facing the more volatile or the more stable environment-depends on whether the project input is a monetary investment or personally-costly effort. With discrete project specific inputs, on the other hand, it is always optimal to split decision rights symmetrically between the managers provided they face comparable levels of operating volatility. This runs counter to the conventional wisdom that bundling stimulates the provision of complementary inputs. The model also generates empirical predictions for the association of organizational structure and managers' relative incentive strength: bundling of decision rights results in PPS divergence across divisions; splitting them results in PPS convergence.

(6) A Rationale for Imperfect Reporting Standards. With Henry Friedman and John Hughes

The aim of general purpose financial reporting is to provide information that is useful to investors, lenders, and other creditors. With this goal, regulators have tended to mandate increased disclosure. We show that increased mandatory disclosure can weaken a firm's incentive to acquire and voluntarily disclose information. Specifically, we provide conditions under which a regulator, seeking to maximize the total amount of information provided to investors via both mandatory and voluntary disclosures, would impose an imperfectly informative mandatory reporting regime even when a perfectly informative regime entails no direct costs. The results contribute to our understanding of potential interactions between mandatory reporting and voluntary disclosure, and demonstrate a novel benefit of accounting standards that mandate imperfectly informative reports.

(7) Optimal Information Design and Incentive Contracts with Performance  Measure Manipulation. With Robert Gox

We study how a firm owner motivates a manager to create value by optimally designing an information system and a compensation contract based on a manipulable performance measure. In equilibrium, the firm either implements a perfect or an uninformative system. The information system and the pay-performance sensitivity (PPS) of the compensation contract can be substitutes in a sense that the firm optimally combines a perfect information system with a low PPS or an uninformative system with a high PPS. Because the information design is endogenous, firms facing relatively high manipulation threat may offer financial incentives that are higher-powered than the ones offered by their peers facing lower manipulation threat. If the manager is in charge of implementing the information system, he chooses a perfect one unless the firm uses the information for internal control. The firm may prefer to commit to an internal control level before observing  any information. 

(8) How Does Media Coverage Affect Corporate Disclosures? With Elyashiv Wiedman

This paper considers the effect that external sources of information, such as media, have on firm disclosure. A manager, who may be endowed with accurate information about the value of the firm, decides whether to voluntarily disclose this information to the market. The manager maximizes firm price, which reflects the expected firm value, conditional on the disclosure and a media report. The media representative (journalist) always observes and truthfully communicates, in a news report, a noisy signal of the firm value. We focus on the dynamic interaction between the manager’s disclosure and the news report. If the manager discloses before or simultaneously with the news report, he or she withholds some values that would have been disclosed in the absence of media coverage. We further find that, if the manager waits until after the media report, he may respond with a disclosure of some information that is less favorable than the media report but may also withhold some more favorable information. As one would expect, if the manager does not respond to the news report, the price drops. However, we find that the price may drop even if the manager responds. This happens when the manager discloses values that, while decreasing the price, still keep it above the price that would have prevailed had the manager remained silent
