Auditor going concern modifications (GCMs) are intended to provide market participants with information related to financial distress, and prior research suggests that the disclosure of a GCM elicits a substantial negative market reaction from investors. In this study, we investigate the market reaction to GCMs in a contemporary disclosure regime and consider whether the observed market reaction is confounded by other material disclosures. We find that the majority of GCMs are issued concurrently with earnings announcements (EAs) and that EAs in the year of new GCMs elicit large negative cumulative abnormal returns (CARs). We also find that CARs surrounding GCMs are significantly more negative when GCMs are disclosed with EAs versus following EAs. We then evaluate whether GCMs convey distress that is incremental to EA disclosures by measuring i) the market reaction to GCMs disclosed following EAs, and ii) whether EA CARs are substantially more negative for companies disclosing GCMs with EAs as opposed to after EAs. In both cases, we find that the incremental market response to GCMs is statistically weak and much smaller in economic magnitude than is suggested by prior research. Finally, we find that management disclosures in EAs, rather than the presence of a GCM, appear to convey information that investors use to anticipate bankruptcy. Taken together, these findings suggest that GCMs are confounded by other significant disclosures and that the informational benefits of GCM reporting are significantly smaller than previously thought. 相似文献

Background
Arterial hypertension is a widely spread disease which can lead to serious adverse events. On the one hand, an optimal therapy should be provided, and on the other hand it is of major importance to search actively for opportunities to further improve usual care.Objectives
The objective is to conduct a literature review about “Improvement of health care by telemonitoring in patients with arterial hypertension”. Moreover, potential target groups for telemonitoring and the cost-effectiveness of telemonitoring are discussed.Methods
Firstly, it was searched for relevant reviews with help of predefined search terms and in- and exclusion criteria (2005–2015). Subsequently, the second step consisted of a literature search for RCTs (2013–2015). The final studies (12 reviews/6 RCTs) were systematically analyzed and summarized in a qualitative way.Results
It is clear that blood pressure telemonitoring is able to lower blood pressure additionally to usual care. With regards to emerging costs, telemonitoring is initially associated with higher costs. When long-term effects are taken into account, telemonitoring can be classified as cost-effective (1 study). Furthermore, specific patient subgroups (such as patients with uncontrolled hypertension) can particularly benefit from telemonitoring.Conclusions
It is clear that telemonitoring results in an additional reduction of blood pressure compared to usual care. High risk groups can particularly benefit from telemonitoring. Future telemedical studies should focus more on health economic aspects as the current evidence is limited.103.
Antitrust scholars have argued that exclusive contracts have anticompetitive, or at best neutral effects, if no efficiencies are generated. In contrast, this paper shows that exclusive contracts can have procompetitive effects, provided buyers are imperfect downstream competitors and contract breach is feasible. In that case, an efficient entrant is not necessarily foreclosed through exclusive contracts but induces buyers to breach. Because breaching buyers have to pay expectation damages to the incumbent, the downstream profits they obtain when breaching must be large enough. Therefore, the entrant needs to set a lower wholesale price than absent exclusive contracts, leading to lower final consumer prices and higher welfare. 相似文献

This paper progresses an analysis of what it means to be a cellular network operator and what form the ownership and control of future cellular networks may take. Alternative modes of ownership may allow for the creation of more flexible cellular networking environments in which competition for packages of resources, that is, the licenced spectrum, the RAN and core network, ensures that the most efficient and innovative architectures, services and applications are delivered to the consumer. This paper develops the concept of the Cellular Network Cloud and Utility Cellular Networking as a means to explore the possibilities for such revolution in the way in which cellular networks are owned and operated. Changes to current industry practices which would help to meet the objectives of more flexible and competitive network ownership and control are proposed. 相似文献

Many of the pressing questions currently facing accounting education researchers are best addressed through experimental research. For example, experiments are useful in testing the effect of innovative educational practices on student learning. The purpose of this paper is to briefly review the literature addressing sources of invalidity which may cloud the results of experiments and describe several procedures which are helpful in controlling for these sources of invalidity. Examples are provided, from published accounting education research studies, which illustrate how researchers have attempted to address several of these threats to validity. Experiments must be carefully planned and designed, so the experiment on completion fulfills the objectives of the researcher. Although experiments are more difficult to conduct in the educational environment than in a scientist's laboratory, many procedures are available to assist accounting education researchers in designing tightly controlled experiments. 相似文献

We examine changes in the association between auditor type (Big 4, Second‐Tier, and Other non‐Big 4) and perceived financial reporting credibility in the wake of events (e.g., Andersen's failure, the implementation of SOX, creation of the PCAOB, etc.) which led to significant growth in Second‐Tier client portfolios and increased scrutiny of Second‐Tier audit practices. Our results reveal that financial reporting credibility of Second‐Tier clients was lower than that of Big 4 clients and was indistinguishable from that of Other non‐Big 4 clients pre‐Andersen. However, post‐Andersen, we find that financial reporting credibility of Second‐Tier clients is higher than that of Other non‐Big 4 clients and is indistinguishable from that of Big 4 clients. We expect that our results will be of interest to regulators, both in the United States and in the European Union, who have expressed concerns about the current state of competition in the audit market, management and boards of directors that are contemplating switching to a Second‐Tier audit firm, and academics investigating quality differences among audit firm types. 相似文献

A dynamic optimization model of parents choosing investments in their children's health motivates an empirical model of parents' choices of health inputs for their children and the impacts of these decisions on their children's subsequent health. Estimates of the child health input demand functions and the child health production functions from the Cebu Longitudinal Health and Nutrition Survey accord with the prediction that optimizing behavior results in higher levels of aggregate child health. Observable parental behaviors respond to the physical developmental status of their children. These parental responses appear to yield large and statistically significant improvements in children's early physiological outcomes. However, because some health inputs choices are not observable, it is impossible to ascertain whether these measured effects are due solely to variations in the observed input choices. 相似文献
