Knowledge that Transforms

This paper examines linkages between audit and nonaudit fees and accrual quality. We measure accrual quality by the Francis, Lafond, Olsson, and Schipper 2005 modification of the Dechow and Dichev 2002 measure. We posit that in settings where audit quality is compromised by a loss of auditor independence, managers use accruals more opportunistically and thereby drive down the accrual quality. Conversely, higher audit effort and quality translate to better accrual quality. Our dependent variables are the relative magnitude of nonaudit fees to audit fees and the absolute magnitudes of audit, nonaudit, and total fees. Results show that accrual quality has a significant negative association with the magnitude of nonaudit fees and a significant positive association with audit fees. This latter result is consistent with the proposition that higher audit fees reflect higher audit effort and better judgements about the propriety of accruals, but is not consistent with the proposition that audit fees are associated with economic bonding.

A company officer is an "alumnus" if he previously worked for an audit firm. Iyer, Bamber, and Barefield (1997) find that alumni have ties with their former audit firms and alumni are more inclined to provide economic benefits to former firms if they have stronger ties. If the alumnus is a senior corporate officer, the alumnus may benefit his former firm by recommending that the company appoint the firm as its auditor. However, the company's audit committee may be concerned that officer-auditor ties threaten audit quality. Therefore, an independent audit committee may not sanction the appointment of the officer's former firm. This study investigates (a) whether companies tend to appoint officers' former audit firms, and (b) whether independent audit committees mitigate this tendency. We document that companies appoint officers' former firms more often than they appoint alternative audit firms. However, companies are less likely to appoint officers' former firms if audit committees are more independent. This suggests that independent audit committees strengthen audit quality by deterring affiliations between audit firms and officers. © CAAA.

We investigate a sample of 50 firm-events, identified in the Global Research Analysts Settlement, in which analysts were discovered to have acted misleadingly ex post. In this setting, analysts' incentives caused them to issue public disclosures that differed from their private beliefs. We document that these firms' institutional holdings decline significantly during the period in which the analysts issued misleading disclosures. During this period daily small-size trades (a proxy for individual investors) are dominated by buy orders while daily large-size trades (a proxy for institutional investors) are dominated by sell orders. Short interest increases during the event period, consistent with the idea that sophisticated investors are selling. Our estimates of investors' trading losses show that individual investors lost about two and a half times the amount lost by institutions. Overall, the results suggest a wealth transfer from individuals to institutions that is likely attributable to analysts' misleading behavior.

We analyze the role of knowhow acquisition in the formation and duration of joint ventures. Two parties become partners in a joint venture to benefit from each other’s knowhow. Joint operations provide each party with the opportunity to acquire part of its partner’s knowhow. A party’s increased knowhow provides the impetus for the dissolution of the joint venture. We characterize the conditions under which dissolution takes place, identify the party that buys out its partner, determine the time to dissolution, establish its comparative statics, and examine the implications of knowledge acquisition for the desirability of joint venture formation.

We derive an asymptotic expansion formula for option implied volatility under a two-factor jump-diffusion stochastic volatility model when time-to-maturity is small. We further propose a simple calibration procedure of an arbitrary parametric model to short-term near-the-money implied volatilities. An important advantage of our approximation is that it is free of the unobserved spot volatility. Therefore, the model can be calibrated on option data pooled across different calendar dates to extract information from the dynamics of the implied volatility smile. An example of calibration to a sample of S&P 500 option prices is provided.

This article applies the methodology of Bai and Ng (2002, 2004) for decomposing panel data into systematic and idiosyncratic components to both stock returns and turnover panels. This approach works well for both returns and turnover, despite the presence of severe heteroscedasticity and nonstationarity of individual stocks' turnover. We test the mutual fund separation model of Lo and Wang (2000). Trading due to systematic risk in returns can account for 66% of systematic turnover. Thus, portfolio rebalancing due to systematic risk is a very important motive for stock trading. Finally, several common turnover measures may understate the impact of stock trading.
