We model the strategic interaction between fundamental investors and “back-runners,” whose only information is about the past order flow of fundamental investors. Back-runners partly infer fundamental investors’ information from their order flow and exploit it in subsequent trading. Fundamental investors counteract back-runners by randomizing their orders, unless back-runners’ signals are too imprecise. Surprisingly, a higher accuracy of back-runners’ order flow information can harm back-runners and benefit fundamental investors. As an application of the model, the common practice of payment for (retail) order flow reveals information about institutional order flow and enables back-runners to earn large profits.

Interim CEOs are often viewed as caretakers during CEO transition periods. However, the caretaker function does not fully explain the increasing trend in the use of interim CEO appointments. Recent studies suggest that firms also use the interim position to test potential CEO candidates. This paper empirically examines this argument using a hand-collected dataset of 1936 CEO successions between 1994 and 2014. We find evidence that firms consider interim positions as a testing ground for CEO candidates. Specifically, we find that candidates with uncertain managerial abilities are more likely to be initially named as interim CEOs rather than permanent CEOs. We also find that interim CEOs are more likely to be promoted to the permanent CEO position when they have better interim-period performance attributable to managerial skills. Consistent with the testing-ground option hypothesis, we find interim CEOs promoted to the permanent position result in superior long-run performance, suggesting better CEO-firm matches.

We study whether the presence of major customer-supplier relationships affects a supplier's cost of debt. Using 5,704 U.S. corporate bonds issued from 1983 to 2013, we find that the cost of debt tends to be reduced when there are major customer-supplier relationships. This finding is robust to alternative measures of major customer-supplier relationships, subsample analyses, a propensity score matched sample analysis, and an instrumental variables approach. The results are consistent with the certification hypothesis, where a major customer serves as a monitoring and certifying entity for its supplier, thereby reducing information asymmetry between the supplier and its creditors. Moreover, the supplier's cost of debt is further reduced if the issuing supplier has higher asset specificity, whereas suppliers in more competitive industries do not incur the benefits of the validation.

When almost all underlying assets suddenly lose a certain part of their nominal value in a market crash, the diversification effect of portfolios in a normal market condition no longer works. We integrate the crash risk into portfolio management and investigate performance measures, hedging and optimization of portfolio selection involving derivatives. A suitable convex conic programming framework based on parametric approximation method is proposed to make the problem a tractable one. Simulation analysis and empirical study are performed to test the proposed approach.

The Dodd-Frank Act mandates that certain standard over-the-counter (OTC) derivatives must be traded on swap execution facilities (SEFs). Using message-level data, we provide a granular analysis of dealers’ and customers’ trading behavior on the two largest dealer-to-customer SEFs for index credit default swaps (CDS). On average, a typical customer contacts few dealers when seeking liquidity. A theoretical model shows that the benefit of competition through wider order exposure is mitigated by a winner’s curse problem and dealer-customer relationships. Consistent with the model, we find that order size, market conditions, and customer-dealer relationships are important empirical determinants of customers’ choice of trading mechanism and dealers’ liquidity provision.

This study examines how PCAOB international inspections of non-U.S. auditors affect international Merger and Acquisition (M&A) outcomes. We find that clients of inspected auditors are more likely to become acquisition targets after the public disclosure of auditor's inspection report. We also find that deal completion is more likely and deal announcement returns are higher if deals involve targets with auditors for which inspection reports are available. Engagement deficiencies and unremediated quality control deficiencies identified in inspection reports weaken the positive effect of PCAOB oversight on M&A outcomes. Collectively, our results suggest that PCAOB oversight reduces information uncertainty in M&A deals.

A major threat to the development of financial markets in emerging markets is “tunneling.” In China, this took on the form of controlling shareholders diverting assets from listed firms or coercing firms to serve as guarantors on questionable loans. A new set of rules enacted in 2005 prohibited asset diversion for “non-operational” purposes. Firms complying with these rules have experienced a reduction in related party transactions, an increase in investment, and better performance. In contrast, another set of contemporary rules, which aimed to standardize the practice of firms providing loan guarantees, has had very little impact. We attribute the contrasting design, implementation, and effectiveness of these two sets of rules to the difference in enforcement costs of the two types of tunneling activities. Relative to loan guarantees, it is much easier for a third party to determine (ex ante) whether a particular form of diversion destroys firm value, and to verify (ex post) that the losses to the firm resulted from the diversion. Our results highlight the importance of enforceability—laws and regulations that can be enforced at lower costs are more likely to succeed, especially in countries with underdeveloped formal institutions.

Do credit contractions trigger social unrest? To answer this question, we turn to a natural experiment from 1930s China, where the 1933 U.S. Silver Purchase program acts as a shock to bank lending. We assemble a hand-collected data set of loan contracts between banks and firms, labor unrest episodes, and underground Communist Party penetration. The Silver Purchase shock results in a severe credit contraction, and firms borrowing from banks with a larger exposure to it experience increased labor unrest and Communist Party penetration among their workers. These findings contribute to understanding the socio-political consequences of credit shocks.

In this article, we propose two asymmetry measures for stock returns. Unlike the popular skewness measure, our measures are based on the distribution function of the data rather than just the third central moment. We present empirical evidence that the greater upside asymmetries calculated using our new measures imply lower average returns in the cross section of stocks. In contrast, when using the skewness measure, the relationship between asymmetry and returns is inconclusive.

This study examines whether material corporate events that occur during the year-end closing process constrain management's and the auditor's resources and inhibit them from providing high-quality financial reports. For a sample of U.S. company financial reports issued during 2000–2013, we identify material corporate events using Type II subsequent event footnote disclosures (i.e., material events that occur in year t+1, but prior to the issuance of the year t financial statements, yet do not affect amounts recognized in year t). We find that Type II subsequent events are associated with lower financial reporting quality, as measured by the need to subsequently restate the year t financial statements. The increased restatement likelihood only occurs when managers are resource-constrained. Auditors can mitigate the increased restatement risk, but only when they allocate more resources to the engagement. Our results underscore the importance of resource management in the financial reporting and audit processes.
