Trading frequency and event study test specification

We examine the effects of thin trading on the specification of event study tests. Simulations of upper and lower tail tests are reported with and without variance increases on the event date across levels of trading volume. The traditional standardized test is misspecified for thinly traded samples. If return variance is unlikely to increase, then Corrado's rank test provides the best specification and power. With variance increases, the rank test is misspecified. The Boehmer et al. standardized cross-sectional test (Event-study methodology under conditions of event-induced variance, Journal of Financial Economics 30, pp. 253–272) is properly specified, but not powerful, for upper-tailed tests. Lower-tailed alternative hypotheses can best be evaluated using the generalized sign test.     

The impact of prior working papers on auditor evidential planning judgments

There has been significant concern in auditing about the effects of relying on prior working papers in planning audit procedures (“anchoring”). This study employed an experiment with varying information sets: prior working papers, current year information and “scenario” (summarized prior year information). Practicing auditors were asked to design a substantive audit program for a case where changes in the client's environment dictated additional procedures. A consensus program from three partners was used as a bench-mark. Experimental groups were about equally adaptive to the changing environment. However, auditors provided with prior working papers demonstrated lower efficiency. The scenario group exhibited both high relative effectiveness and efficiency, while current information subjects displayed the lowest overall level of performance.     

Qualität im Journalismus – ein integratives Konzept

To determine the various performance criteria concerning journalism it is reasonable to develop a broad concept, which integrates the different theoretical approaches. In a functional and system-oriented perspective, fundamental performance criteria can be based on the social function and the specific code of journalism, which emerged in an historical process of mutual observation of journalists and audiences. In a normative-democratic perspective, performance criteria can be derived from societal and human values codified in diverse regulations. However, in this regard it has to be taken into account that specific claims of the political subsystem also play an important role. Finally from an audience and action oriented viewpoint, it is important to keep in mind that journalistic communication must be useful and applicable in the world the audience lives in.     

Enterprise Risk Management and the Financial Reporting Process: The Experiences of Audit Committee Members,CFOs, and External Auditors

The recent financial crisis has brought to the forefront the need for companies to effectively manage their risks. In this regard, one approach that has gained prominence is enterprise risk management (ERM). Importantly, little is known about the link between ERM and the financial reporting process. This link is critical, because it is imperative that financial reporting adequately depicts the financial status (e.g., valuations, estimates) and associated risks of a company as revealed by ERM. Additionally, from an auditing perspective, ERM affects the risks of misstatement, which should impact audit planning. Accordingly, the objective of this study is to examine the experiences of audit partners, CFOs, and audit committee (AC) members (“the governance triad”) on the link between ERM and the financial reporting process. To determine whether members of the governance triad focus on monitoring, strategy, or both, we also examine their definition of and experiences with ERM with respect to agency and/or resource dependence theory. To address these issues, we conduct semistructured interviews of experienced individuals that form the governance triads from 11 public companies. There are three major findings from our study. First, importantly, all three types of participants see a strong link between ERM and the financial reporting process. Second, despite recognition of the broad nature of ERM, the predominant experiences of the actual roles played by triad members center on agency theory, while resource dependence may be relatively underemphasized by all triad members. Finally, CFOs and AC members indicate that auditors may be especially underutilizing ERM in the audit process, suggesting an “expectations gap.”     

Evaluating a Global Vector Autoregression for Forecasting

Global vector autoregressions (GVARs) have several attractive features: multiple potential channels for the international transmission of macroeconomic and financial shocks, a standardized economically appealing choice of variables for each country or region examined, systematic treatment of long-run properties through cointegration analysis, and flexible dynamic specification through vector error correction modeling. Pesaran et al. (2009) generate and evaluate forecasts from a paradigm GVAR with 26 countries, based on Dées, di Mauro et al. (2007). The current paper empirically assesses the GVAR in Dées, di Mauro et al. (2007) with impulse indicator saturation (IIS)??a new generic procedure for evaluating parameter constancy, which is a central element in model-based forecasting. The empirical results indicate substantial room for an improved, more robust specification of that GVAR. Some tests are suggestive of how to achieve such improvements.

Chinese consumer decision-making styles: A comparison between the coastal and inland regions

China is rapidly becoming an important market for consumer goods, but relatively little is known about variations in consumer shopping patterns in different regions of China. We employ a cultural materialism perspective in understanding decision-making styles of inland and coastal shoppers. Our findings reveal that consumers in the two regional markets do not differ in utilitarian shopping styles but they do in hedonic shopping styles. Marketers need to understand these differences to be able to market effectively to consumers in different regional markets within China.     

UNDERSTANDING THE FINANCIAL CONSEQUENCES OF THE BULLWHIP EFFECT IN A MULTI‐ECHELON SUPPLY CHAIN

This article is concerned with how supply chain strategies can mitigate the Bullwhip Effect and inflated inventories from the perspective of the central firm (typically a manufacturer) in the supply chain. We first outline a base case scenario with a validated system dynamics simulation model, using supply chain characteristics as reported by a real firm, in this case a Mexican electronics supplier to U.S. automobile assemblers. We find, surprisingly, that a lower Bullwhip Effect Index (BE) does not always lead to lower costs in the supply chain studied. Furthermore, sensitivity analysis suggests some interesting, counterintuitive results. The implications of these findings are further developed as we test how lead time reduction can also reduce the Bullwhip Effect in the simulated setting.
