Trading networks and liquidity provision

Journal of Financial Economics 2014 113(2), 235-251
We study the profitability of traders in two fully electronic and highly liquid markets: the Dow and Standard & Poor׳s 500 e-mini futures markets. Using unique information that identify counterparties to a transaction, we show and seek to explain the fact that the network pattern of trades captures the relations between behavior in the market and returns. Our approach includes a simple representation of how much a shock is amplified by the network and how widely it is transmitted. This representation provides a possible shorthand for understanding the consequences of a fat-finger trade, a withdrawing of liquidity, or other market shock.

How Should Control Theory Be Used to Calculate a Time-Consistent Government Policy?

Review of Economic Studies 1988 55(2), 263
We study different solutions to a simple one-dimensional linear quadratic game with a large number of private agents and a government. A “time-consistent” solution is defined as a solution to the Hamilton-Jacobi-Bellman equation, i.e. as a policy for which the government has noprecommitment capability. This solution is compared to a policy where the government has an “instantaneous” pre-commitment, i.e. an equilibrium in which the government has a period by period leadership. In both cases, we show how control theory should be applied to calculate the equilibrium and how to relate these equilibria to the differential game literature.

The Price Is (Almost) Right

Journal of Finance 2009 64(6), 2739-2782
Most previous research tests market efficiency using average abnormal trading profits on dynamic trading strategies, and typically rejects the joint hypothesis of market efficiency and an asset pricing model. In contrast, we adopt the perspective of a buy‐and‐hold investor and examine stock price levels. For such an investor, the price level is more relevant than the short‐horizon expected return, and betas of cash flow fundamentals are more important than high‐frequency stock return betas. Our cross‐sectional tests suggest that there exist specifications in which differences in relative price levels of individual stocks can be largely explained by their fundamental betas.

The Value Spread

Journal of Finance 2003 58(2), 609-641
We decompose the cross‐sectional variance of firms' book‐to‐market ratios using both a long U.S. panel and a shorter international panel. In contrast to typical aggregate time‐series results, transitory cross‐sectional variation in expected 15‐year stock returns causes only a relatively small fraction (20 to 25 percent) of the total cross‐sectional variance. The remaining dispersion can be explained by expected 15‐year profitability and persistence of valuation levels. Furthermore, this fraction appears stable across time and across types of stocks. We also show that the expected return on value‐minus‐growth strategies is atypically high at times when their spread in book‐to‐market ratios is wide.

PCAOB Inspections: Public Accounting Firms on “Trial”

Contemporary Accounting Research 2019 36(2), 694-731
The objective of our article is to obtain a better understanding of how auditors anticipate the potential for PCAOB inspection, experience the inspection, cope with the consequences of the inspection, and understand the PCAOB's influence within the context of professionalism. We use a qualitative approach that uses both surveys (55) and interviews (20) of auditors (of varying rank and firm) across a five‐year period (2012–2017). Respondents suggest that PCAOB inspectors are powerful, representing the “prosecution,” “judge,” and “jury” of the auditing profession. We therefore use a structural metaphor of the PCAOB inspection as a judicial “trial.” By controlling the criteria used to evaluate performance, inspectors have the power to repeatedly “subpoena,” “interrogate,” and return a “verdict” on the firm (auditor); those judged as “guilty” require supervised “probation.” This process is perceived as having improved audit quality but at a cost. Passing an inspection is so important that auditors (firms) have resorted to impression management strategies and “functionally stupid” work practices (e.g., excessive documentation, a decrease in critical thinking as a result of a “box ticking” approach to auditing). Furthermore, some respondents believe that being a good auditor has come at the expense of being a good accountant; the emphasis on audit process and concurrent de‐emphasis on technical accounting could ultimately lead to audits themselves falling short. In addition, it is evident that inspectors and auditors differ in their perceptions of risk, likely manifesting because inspectors are standards‐focused while auditors (firms) are methodology‐focused. Finally, the inspection process has created excessive stress and tension, beyond budget and fee pressures, which some auditors perceive as affecting the pool of talented auditors that firms may be able to attract and retain in the future.

Corporate Governance and the Audit Process*

Contemporary Accounting Research 2002 19(4), 573-594
There has been growing recognition in recent years of the importance of corporate governance in ensuring sound financial reporting and deterring fraud. The audit serves as a monitoring device and is thus part of the corporate governance mosaic. The objective of this paper is to examine the impact of various corporate governance factors, such as the board of directors and the audit committee, on the audit process. Importantly, there is little professional guidance on how auditors should consider such factors when formulating an appropriate audit strategy, and there has been only one prior study on this issue (Cohen and Hanno 2000). Because there are no current specific auditing standards that relate to the effect of corporate governance on the audit process, we conducted a semi‐structured interview with 36 auditors on current audit practices in considering corporate governance in the audit process. Reflecting on client experiences, auditors indicate a range of views with regard to the elements included in the rubric of “corporate governance”. Most significantly, auditors view management as the primary driver of corporate governance. The inclusion of top management in the “corporate governance mosaic” is inconsistent with agency theory's prescription of the board and other mechanisms serving as a means to independently oversee management's actions to protect stakeholders. Auditors consider corporate governance factors to be especially important in the client acceptance phase and in an international context. Further, despite the attention placed on the audit committee in the academic literature, in the business community, and by regulators in different countries (e.g., Canada, United States, Australia), several respondents indicated that their experiences with their clients suggest that audit committees are typically ineffective and lack sufficient power to be a strong governance mechanism. Implications for research and practice are presented.
