In response to the public criticism of the inadequate disclosures mandated by SFAS No. 157, Fair Value Measurements, the FASB issued ASU (Accounting Standards Update) 2010–06, Improving Disclosures about Fair Value Measurements, and ASU 2011–04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements, in an effort to increase the reporting transparency. We examine whether the increased fair value disclosures required by these two updates effectively decrease crash risk, defined as the frequency of extreme negative stock returns. In support of the hypothesis, we find that increased transparency from these updates reduces crash risk among U.S. banking firms and that the reduction is greater in banks that have a higher level of Level 3 financial assets.  相似文献

ABSTRACT

The purpose of the study was to present a comprehensive view on the associations among polychronicity, job satisfaction, work engagement, and turnover intention within a restaurant context. Using a sample of 252 servers in full-service restaurants, structural equation modeling results found that polychronicity positively linked with job satisfaction, work engagement, and turnover intention. An indirect effect from polychronicity to job satisfaction to turnover intention was found. Results can assist restaurant managers in selecting candidates that best fit their organization. It will also assist employees in determining which career path best matches their personality traits.  相似文献

We study parametric and non‐parametric approaches for assessing the accuracy and coverage of a population census based on dual system surveys. The two parametric approaches being considered are post‐stratification and logistic regression, which have been or will be implemented for the US Census dual system surveys. We show that the parametric model‐based approaches are generally biased unless the model is correctly specified. We then study a local post‐stratification approach based on a non‐parametric kernel estimate of the Census enumeration functions. We illustrate that the non‐parametric approach avoids the risk of model mis‐specification and is consistent under relatively weak conditions. The performances of these estimators are evaluated numerically via simulation studies and an empirical analysis based on the 2000 US Census post‐enumeration survey data.  相似文献

This paper explores the contracting costs of conducting mergers and acquisitions (M&A), creates a theoretical model of the information asymmetry involved, and shows how buying firms employ several mechanisms to reduce such asymmetry. Extending prior literature, the paper examines these costs in both domestic and cross‐border settings using a sample of over 3000 M&A deals. I consider both the fees paid and the time required in the bargaining phase to be contracting costs, and model them simultaneously to help explicate their endogenous relationship. The results show that buyers in cross‐border deals are more likely to employ mechanisms to affect information asymmetry, while the employment of these mechanisms affects contracting costs. The results help to explain why cross‐border M&A are more costly yet more quickly executed. Finally, modelling the use and effects of the mechanisms is sufficient to explain the contracting cost differences between domestic and cross‐border M&A.  相似文献

This article investigates the effects of information and communication technologies (ICT) on female labor force participation in a sample of 48 African countries. We specify and estimate linear regression and dynamic panel data models with fixed effects (FE) and system-generalized method of moments (SYS-GMM) estimation over the period 2001–2017. The three main results are that ICT use (mobile phone and internet) significantly stimulates female labor force participation in Africa; this effect is enhanced by financial development and female education; the effect of ICT on female employment in Africa is strongest in the industrial sector. These results remain robust to the provision of social, cultural, and institutional variables.  相似文献

The apparent success of state‐managed market economies has challenged the conventional wisdom that liberal democracy is the norm around which all capitalist countries tend to converge. If the link between democracy and development is more tenuous than we often think, the authoritarian variety of capitalism is not without its own problems, especially with respect to political legitimacy, innovation and regional development. This article explores these issues through the prism of ‘authoritarian modernization’ in Russia. We argue that this strategy is unlikely to succeed, even in its own terms, because (1) the political system fails to create favourable institutional conditions for modernization; (2) the economic system is beset by deeply embedded structural problems; and (3) the regional policy apparatus is torn between the goals of spatial equalization and spatial agglomeration. The article focuses on the Skolkovo Innovation Centre, the main symbol of Russian modernization, to demonstrate the territorial repertoire of the mega‐project, a state‐sponsored development strategy to create innovation clusters from above because they cannot emerge from below.  相似文献

Previous studies demonstrate the detrimental effect of ethical conflict (i.e., incompatibility between ethical values of employees and organizations) on employee organizational commitment. However, few studies have assessed the underlying mechanisms and boundary conditions that may contribute to a deeper understanding of how and when the detrimental effect manifests. Drawing on the transactional model of stress and literature on the moral self, our study examines the psychological strain as a key intermediate mechanism that channels the negative relationship between the ethical conflict and organizational commitment. Furthermore, we posit that employees with different levels of moral identity and moral efficacy may suffer differently from ethical conflict. We tested our research model with two-wave lagged data obtained from 265 healthcare employees and found that the indirect, negative effect of ethical conflict on organizational commitment via psychological strain is strongest among employees with high moral identity and low moral efficacy. Interestingly, results show that employees with low moral identity and high moral efficacy do not suffer from ethical conflict. These findings suggest that ethical conflict is differentially harmful to employees and that a more nuanced understanding of its contingent effects is needed.  相似文献
