In classical perfect and complete markets, prices form a Martingale and stock returns (or equivalently, successive price changes) are serially uncorrelated. However, there is considerable evidence in the finance literature showing that stock returns are serially correlated both in the short and...

We show that in markets with asymmetric information, even if there is full agreement on the choice of optimal information quality, entrusting the choice of (unverifiable) public information quality to traders who benefit from such information leads to inefficiencies. However, delegation of...

This paper examines an aspect of Security Class Action dynamics that has not been previously analyzed using game theory: the effects of fragmentation of interests across the insured defendant and potentially multiple-insurers who are all subject to losses under the class action. Incentive...

The immediate expensing of Ramp;D expenditures is often justified by the conservatism principle. However, no accounting procedure consistently applied can be conservative throughout the firm' life. We ask the following questions: (a) When is the expensing of Ramp;D conservative and when is it...

The fact that auditors are paid by the companies they audit creates an inherent conflict of interest with investors who rely on the audit report in their capital allocation decisions. We analyze how the provision of financial statement insurance could eliminate this conflict of interest and...

This paper aims to understand the determinants of lawsuits against auditors in securities class action litigation and the settlement pattern by auditors when the suit is not dismissed. The issues we consider are: (i) when are auditors named as defendants (ii) when do auditors choose to settle...

This study examines whether expected rate of return (ERR) manipulation is related to disclosure of pension asset allocation. FAS 132R(1), which requires firms to disaggregate the detailed categories of pension asset allocation, provides a natural experiment for studying the effect of enhanced...

This study examines the effect of internal control weaknesses (ICWs) on managers' choice of pension assumptions, using data disclosed under Sarbanes-Oxley Section 404 from 2004 to 2012. We hypothesize that firms with ICWs are better able to opportunistically set pension assumptions, such as the...

We examine the joint pricing effects of restatement announcements and associated MW disclosures. First, we analyze whether a dual disclosure of both a MW and restatement is viewed more adversely by the market at the time of restatement. We show that firms that announce both a restatement and an...

Auditing may be viewed as an arrangement for reducing inefficiencies arising from the fundamental market conflict between a seller who wants as high a price as possible and a buyer who wants to pay as low a price as possible. In more general terms, sellers prefer policies that boost the stock...
