Identification of Maximal Affine Term Structure Models

Building on Duffie and Kan (1996) , we propose a new representation of affine models in which the state vector comprises infinitesimal maturity yields and their quadratic covariations. Because these variables possess unambiguous economic interpretations, they generate a representation that is globally identifiable. Further, this representation has more identifiable parameters than the “maximal” model of Dai and Singleton (2000) . We implement this new representation for select three‐factor models and find that model‐independent estimates for the state vector can be estimated directly from yield curve data, which present advantages for the estimation and interpretation of multifactor models.     

Bank Competition: Measurement,Decision‐Making,and Risk‐Taking

This paper investigates whether greater competition increases or decreases individual bank and banking system risk. Using a new text‐based measure of competition, and an instrumental variables analysis that exploits exogenous variation in bank deregulation, we provide robust evidence that greater competition increases both individual bank risk and a bank's contribution to system‐wide risk. Specifically, we find that higher competition is associated with lower underwriting standards, less timely loan loss recognition, and a shift toward noninterest revenue. Further, we find that higher competition is associated with higher stand‐alone risk of individual banks, greater sensitivity of a bank's downside equity risk to system‐wide distress, and a greater contribution by individual banks to downside risk of the banking sector.     

The Determinants of Long‐Term Corporate Debt Issuances

A significant proportion of the debt issued by investment‐grade firms has maturities greater than 20 years. In this paper we provide evidence that gap‐filling behavior is an important determinant of these very long‐term issues. Using data on individual corporate debt issues between 1987 and 2009, we find that gap‐filling behavior is more prominent in the very long end of the maturity spectrum where the required risk capital makes arbitrage costly. In addition, changes in the supply of long‐term government bonds affect not just the choice of maturity but also the overall level of corporate borrowing.     

Worrying about the Stock Market: Evidence from Hospital Admissions

Using individual patient records for every hospital in California from 1983 to 2011, we find a strong inverse link between daily stock returns and hospital admissions, particularly for psychological conditions such as anxiety, panic disorder, and major depression. The effect is nearly instantaneous (within the same day) for psychological conditions, suggesting that anticipation over future consumption directly influences instantaneous utility.     

Forecasting the PSBR Outside Government: The IFS Perspective

Expectations regarding the future state of the public finances are vital for public policy formation. The UK experience has been that forecast of the PSBR have been beset with problems since the mid-1980s. Independent assessments of the accuracy and plausibility of public finance forecasts are an important check on government forecasts and serve to increase public debate over government finance issues. We examine the success of various possible methods available to those outside government. JEL classification: E6, H1, H6.     

Mandatory Disclosure and Operational Risk: Evidence from Hedge Fund Registration

Mandatory disclosure is a regulatory tool intended to allow market participants to assess operational risk. We examine the value of disclosure through the controversial SEC requirement, since overturned, which required major hedge funds to register as investment advisors and file Form ADV disclosures. Leverage and ownership structures suggest that lenders and equity investors were already aware of operational risk. However, operational risk does not mediate flow‐performance relationships. Investors either lack this information or regard it as immaterial. These findings suggest that regulators should account for the endogenous production of information and the marginal benefit of disclosure to different investment clienteles.     

Bank Lending Standards and Access to Lines of Credit

This paper examines how changes in bank lending standards are related to the availability of bank lines of credit for private and comparable public firms. Overall, we find that access to lines of credit is more contingent on bank lending standards for private than for public firms. The impact of bank lending standards is however asymmetric: while private firms are less likely than public firms to gain access to new lines when credit market conditions are tight, we find no difference between public and private firms in terms of their use or retention of pre‐existing lines. We also find that private firms without lines of credit use more trade credit when bank lending standards are tight, which is suggestive of a supply effect. Overall, the evidence suggests that “credit crunches” are likely to have a disproportionate impact on private firms. However, pre‐existing banking relationships appear to mitigate the impact of these contractions on private firms.     

Closing the Loop: Review Process Factors Affecting Audit Staff Follow‐Through

The PCAOB recently expressed concern regarding the sufficiency and effectiveness of review and supervision of audit fieldwork. For the audit review process to succeed as a quality control mechanism, any issues or questions identified by a reviewer must be adequately resolved and documented in the workpapers. If audit review fails to correct for errors/biases in the work of reviewees, there can be serious detrimental effects on audit quality and, in turn, financial statement quality. Our study extends the literature by examining the phase of the review process in which reviewees respond to (or “close”) notes/comments provided by their reviewers. Utilizing an experiment, we find that certain contextual factors (review timeliness and review note frame) influence reviewee follow‐through during this critical phase. Specifically, we find that a delayed review elicits significantly lower effort levels than a timely review. Review note frame (i.e., how the reviewer phrases the rationale given for the underlying directive of a review note) significantly affects reviewee effort and performance when the review is timely. Through mediation analyses, we explore the mediating effect of effort on performance. In addition, we find that reviewer delay leads to greater over‐documentation.     

Taking a View: Corporate Speculation, Governance, and Compensation

Using responses to a well‐known confidential survey, we study corporations' use of derivatives to “take a view” on interest rate and currency movements. Characteristics of speculators suggest that perceived information and cost advantages lead them to take positions actively; that is, they do not speculate to increase risk by “betting the ranch.” Speculating firms encourage managers to speculate through incentive‐aligning compensation arrangements and bonding contracts, and they use derivatives‐specific internal controls to manage potential abuse. Finally, we examine whether investors reading public corporate disclosures are able to identify firms that indicate speculating in the confidential survey; they are not.
