Theory suggests that financial report-based debt covenants engender incentives for the manager to relax covenant constraints through accounting choices in order to avoid costly covenant violations. Prior studies directly testing this hypothesis in the context of financial misreporting fail to find consistent evidence. Using a more refined measure of debt covenant restriction, we find that debt covenant restriction is positively associated with the probability of financial statement misstatements. This positive association is driven by performance covenants rather than capital covenants and is more consistent with the manager striving to avoid a “false-positive” violation than to delay the violation. Our results also imply that managers resort to both income-increasing and non–income-increasing misreporting to relieve covenant constraints and rely more on the latter when faced with greater earnings management constraints. Additionally, the auditor charges higher audit fees to firms with more binding covenants even outside the violation state, and audit fees increase with constraints relative to both performance and capital covenants, reflecting greater financial reporting risk and bankruptcy risk, respectively. Within capital covenants, we find some evidence of even higher audit fees for tighter intangible-inclusive versus intangible-exclusive capital covenants. Lastly, our evidence suggests that the positive association between covenant constraints and misreporting is attenuated when the auditor has more experience with debt covenants, has greater bargaining power over the client, or faces greater litigation risk.  相似文献

Aims: This study compared the risk for major bleeding (MB) and healthcare economic outcomes of patients with non-valvular atrial fibrillation (NVAF) after initiating treatment with apixaban vs rivaroxaban, dabigatran, or warfarin.

Methods: NVAF patients who initiated apixaban, rivaroxaban, dabigatran, or warfarin were identified from the IMS Pharmetrics Plus database (January 1, 2013–September 30, 2015). Propensity score matching (PSM) was used to balance differences in patient characteristics between study cohorts: patients treated with apixaban vs rivaroxaban, apixaban vs dabigatran, and apixaban vs warfarin. Risk of hospitalization and healthcare costs (all-cause and MB-related) were compared between matched cohorts during the follow-up.

Results: During the follow-up, risks for all-cause (hazard ratio [HR]?=?1.44, 95% confidence interval [CI]?=?1.2–1.7) and MB-related (HR?=?1.57, 95% CI?=?1.0–2.4) hospitalizations were significantly greater for patients treated with rivaroxaban vs apixaban. Adjusted total all-cause healthcare costs were significantly lower for patients treated with apixaban vs rivaroxaban ($3,950 vs $4,333 per patient per month [PPPM], p?=?.002) and MB-related medical costs were not statistically significantly different ($100 vs $233 PPPM, p?=?.096). Risk for all-cause hospitalization (HR?=?1.98, 95% CI?=?1.6–2.4) was significantly greater for patients treated with dabigatran vs apixaban, although total all-cause healthcare costs were not statistically different. Risks for all-cause (HR?=?2.22, 95% CI?=?1.9–2.5) and MB-related (HR?=?2.05, 95% CI?=?1.4–3.0) hospitalizations were significantly greater for patients treated with warfarin vs apixaban. Total all-cause healthcare costs ($3,919 vs $4,177 PPPM, p?=?.025) and MB-related medical costs ($96 vs $212 PPPM, p?=?.026) were significantly lower for patients treated with apixaban vs warfarin.

Limitations: This retrospective database analysis does not establish causation.

Conclusions: In the real-world setting, compared with rivaroxaban and warfarin, apixaban is associated with reduced risk of hospitalization and lower healthcare costs. Compared with dabigatran, apixaban is associated with lower risk of hospitalizations.  相似文献

Estimation, inference and interpretation of the causal effects of programs and policies have all advanced dramatically over the past 25 years. We highlight three particularly important intellectual trends: an improved appreciation of the substantive importance of heterogeneous responses and of their methodological implications, a stronger focus on internal validity brought about by the “credibility revolution,” and the scientific value that follows from grounding estimation and interpretation in economic theory. We discuss a menu of commonly employed partial equilibrium approaches to the identification of causal effects, emphasizing that the researcher's central intellectual contribution always consists of making an explicit case for a specific causal interpretation given the relevant economic theory, the data, the institutional context and the economic question of interest. We also touch on the importance of general equilibrium effects and full cost–benefit analyses.  相似文献

Recently, the Public Company Accounting Oversight Board (PCAOB) issued a concept release soliciting public recommendations to improve auditor independence and audit quality (PCAOB, 2011). The focus of the release is on mandatory audit firm rotation (MAFR) with a request for commentaries addressing the advantages and disadvantages of MAFR. In this paper, we briefly summarize the recent literature on mandatory audit firm rotation and suggest how it can be useful to regulators as they consider the implementation of mandatory rotation. We find that the conclusions reached about the possible effectiveness of MAFR appear to depend on the type of data used (voluntary vs. mandatory auditor changes), suggesting that regulators should exercise care when drawing inferences from past audit firm rotation research.  相似文献

I develop and analyze a set of cross‐country facts regarding employment and wage setting institutions over the decade surrounding the 2008 financial crisis. Among long‐industrialized countries, young adult employment declined more than prime age employment over this time period. I show that differences in countries' wage setting institutions strongly predict variations in the magnitude of declines in young adult employment. Both unconditionally and conditional on changes in macroeconomic conditions, young adult employment declined 5 percentage points less in countries where wage setting is driven by collective bargaining arrangements than in countries with statutory wage floors. Evidence on the evolution of legislated minimum wage rates and of an asymmetry in the relationship between growth and young adult employment suggest an important role for a standard “wage rigidity” mechanism.  相似文献

With the growing rise in consumer spending and economic power in Asian societies, it is increasingly important to explore the implications of these developments on consumer culture. This cross‐cultural study first discusses the rise of materialism and conspicuous consumption in post‐revolution China then examines differences in these phenomena between young adult consumers, aged 18–35, living in urban China and the United States. Utilizing survey data from over 600 respondents, significant differences were found in both materialism and conspicuous consumption, with Chinese young adults scoring higher in both variables. The findings show, that compared with past comparative studies, it appears both materialism and conspicuous consumption are on the rise among urban Chinese consumers.  相似文献
