Semitractability of optimal stopping problems via a weighted stochastic mesh algorithm

In this paper, we propose a Weighted Stochastic Mesh (WSM) algorithm for approximating the value of discrete‐ and continuous‐time optimal stopping problems. In this context, we consider tractability of such problems via a useful notion of semitractability and the introduction of a tractability index for a particular numerical solution algorithm. It is shown that in the discrete‐time case the WSM algorithm leads to semitractability of the corresponding optimal stopping problem in the sense that its complexity is bounded in order by with being the dimension of the underlying Markov chain. Furthermore, we study the WSM approach in the context of continuous‐time optimal stopping problems and derive the corresponding complexity bounds. Although we cannot prove semitractability in this case, our bounds turn out to be the tightest ones among the complexity bounds known in the literature. We illustrate our theoretical findings by a numerical example.     

Testing Macro Models by Indirect Inference: A Survey for Users

With Monte Carlo experiments on models in widespread use we examine the performance of indirect inference (II) tests of DSGE models in small samples. We compare these tests with ones based on direct inference (using the Likelihood Ratio, LR). We find that both tests have power so that a substantially false model will tend to be rejected by both; but that the power of the II test is substantially greater, both because the LR is applied after re-estimation of the model error processes and because the II test uses the false model’s own restricted distribution for the auxiliary model’s coefficients. This greater power allows users to focus this test more narrowly on features of interest, trading off power against tractability.

Using Signals to Initiate Importer-Exporter Relationships: Evidence from Vietnamese Importers

ABSTRACT

Purpose: Realizing the existence of information asymmetry in export markets and the use of signals to distinguish high-qualified sellers from low-qualified sellers, this study investigates the effects of signal consistency and signal clarity on exporter credibility, and subsequently, importer relationship intention.

Methodology: Using a survey data set collected from a systematic sample of 418 Vietnamese importers, the authors tested a model hypothesizing the impact of signal consistency and signal clarity on exporter credibility, and subsequently, on importer relationship intention.

Findings: The authors found that signal consistency and clarity have a positive impact on exporter credibility. Signal consistency also enhances the level of signal clarity. They also found that exporter credibility underlies importer relationship intension.

Research Implications: Under the condition of information asymmetry, importers face difficulties in identifying and evaluating the best supplier among available suppliers in order to make the most appropriate selection decision. The findings confirm that signal clarity and consistency can help exporters to overcome such problems. Exporters should ensure that all signals sent to importers are clear and consistent over time to encourage importers to build long-term business relationships with them.

Contributions: The findings of this study add to the literature on signaling in exporter–importer relationships and can serve as an initiation for further research in the area in transitioning economies.     

Upper‐echelon executive human capital and compensation: Generalist vs specialist skills

This study extends current knowledge of upper echelon executive compensation beyond the CEO, specifically CFO compensation, based on whether they possess generalist or specialist skills. We find that “strategic” CFOs with an elite MBA (generalist) consistently command a compensation premium, while “accounting” CFOs (specialist) and CFOs with a non‐MBA master's degree, even from an elite institution, do not. Further, scarce “strategic” CFOs are awarded both higher salaries and higher equity‐based compensation. Our findings support the view that unique complementarities between scarce CFOs and firms increase these executives' bargaining power leading to pay premium. Our results are robust to post‐hiring years, firm sizes, board characteristics, and CFO's insider/outsider status. We contribute at the confluence of upper‐echelon compensation, executive human capital, resource‐based view, and assortative matching literatures. Copyright © 2014 John Wiley & Sons, Ltd.     

Is the quality of female auditors really better? Evidence based on the Chinese A-share market

Unlike previous studies in which a single index was used to measure audit quality, this study establishes a new comprehensive index to measure audit quality via Discretionary Accrual, as estimated by Jones’ basic model (1991) and Audit Opinions. The former is used to measure the quality of financial statements, and the latter is used to measure the auditors’ independence in the mainstream international literature. We examine whether and how an auditor’s gender affects the quality of his or her audits under the framework of empathy theory and gender role socialization theory. Using a large sample of 9861 auditor-firm-year observations from Chinese A-share–listed companies from 2011 to 2015, we find that the audit quality of signed auditors shows significant gender differences: these significant gender differences differ from the findings of previous studies that female auditors could provide a higher-quality audit than male auditors; that is, in our study the audit quality of the male auditors exceeds that of the female auditors. After distinguishing the positive and negative directions of the Discretionary Accrual, we find no significant gender differences in audit quality between male and female auditors when the earnings had been adjusted upward by the client; that is, female and male auditors had the same audit risk perception. However, when the client adjusted earnings downward, which indicates a lower audit risk for the auditor, the audit quality of female auditors was significantly lower than that of the male auditors. After controlling for the age and position of the auditors, we also find that the gender differences in the auditors’ audit quality decreased significantly or even disappeared when the auditor’s age exceeded 45?years and/or their position was manager or above. These results are consistent with the empathy theory and gender role socialization theory.     

Can Management Turnover Restore the Financial Statement Credibility of Restating Firms? Further Evidence

This paper investigates the association between management turnover following financial restatements and the probability of subsequent restatements. We find that restating firms that replace management (CEO and/or CFO) are more likely to restate their financial statements again. We also find that subsequent restatements are mainly attributable to the new management. Overall, our results suggest that management turnover following restatements may not be an effective mechanism to remediate financial restatements, but the change to a new management results in a greater possibility of lower earnings quality (i.e., higher probability of subsequent financial restatements and accruals‐based earnings management). Our study supports prior literature's findings that the change in the top management leads to organizational instability and higher accounting information risk. Our findings have implications for internal decisionmaking with regard to top executive replacement.     

REORGANIZATION AND FINANCIAL DISTRESS: AN EMPIRICAL INVESTIGATION

Prior studies on financial distress focus on the restructuring of one aspect of the firm. By examining various forms of restructuring, we provide empirical evidence that asset restructuring and governance restructuring play significant roles before bankruptcy filing. Our analysis shows that financial restructuring before bankruptcy is influenced by the holdout problem among creditor groups. Evidence suggests that the fraudulent conveyance provision does not pose a serious impediment to divestitures during the two years before bankruptcy. The evidence also indicates that Chapter 11 reorganization is lenient toward management. Although Chapter 11 allows the firm to breach burdensome executory contracts with employees, our findings suggest that union busting is not an important part of the reorganization process. Finally, we identify various financial characteristics to predict the different types of restructuring a firm may undertake.
