The purpose of this study is to examine the role of high-performance work practices (HPWPs) in helping to translate corporate social performance (CSP) into corporate financial performance (CFP). We employ arguments from the behavioral view of human resource management to highlight the vertical connection between a firm's proclivity for CSP and the management practices it adopts. Furthermore, we examine the moderating influence of HPWPs on the CSP–CFP linkage. Results suggest that HPWPs moderate the relationship between CSP and financial outcomes, and suggest that human resource practices may play an important role in enhancing a positive CSP–CFP relationship by helping to vertically align the behaviors of employees with the values and orientation of the organization.  相似文献

Abstract

We examine the determinants of clients’ decision to follow departing partners to new audit firms and the effect of this decision on the likelihood of financial restatements. Using Taiwanese audit partner turnover data from 1984 to 2010, we find that clients are more likely to follow departing partners when the partners have more clients, longer tenure, and when both lead and concurring partners leave simultaneously. By contrast, clients are more likely to stay with their incumbent audit firms when the firms are one of the Big Four or when only the concurring partners leave. The extended partner tenure due to clients following departing partners, however, does not enhance audit quality. In fact, clients that stay at the incumbent firm experience a significant decrease in the probability of financial restatements in the first year after the audit partners leave, but clients that follow do not.  相似文献

This study investigates the relationship between continuing professional education (CPE), a mechanism of professional training, and financial performance of public accounting firms. Both training subject (partner and assistant) and training location (internal and external) are included. Public accounting firms are categorized as big, medium, and small-sized ones. Empirical data are obtained from the 1992–1995 Survey Report of Public Accounting Firms in Taiwan, published by the Financial Supervisory Commission, Executive Yuan, Taiwan, ROC. Univariate test and multiple-regression model are employed to examine the financial performance effects of CPE. Main results indicate that both professional training of assistants and external professional training are positively related to financial performance in big-sized firms. Next, we document a significantly positive association between internal training of assistants and financial performance in either big-, medium-, or small-sized firms. Finally, both external professional training of partners in big-sized firms and external professional training of assistants in small-sized firms are positively related to financial performance. Few prior studies investigate professional training of public accounting firms by a regression model due to availability of empirical data. Accordingly, evidences obtained in this study provide useful information to partners for decision-making in public accounting firms under the considerably competitive audit market.  相似文献

This paper studies minimally-supported D-optimal designs for polynomial regression model with logarithmically concave (log-concave) weight functions. Many commonly used weight functions in the design literature are log-concave. For example, and exp(−x 2) in Theorem 2.3.2 of Fedorov (Theory of optimal experiments, 1972) are all log-concave. We show that the determinant of information matrix of minimally-supported design is a log-concave function of ordered support points and the D-optimal design is unique. Therefore, the numerically D-optimal designs can be constructed efficiently by cyclic exchange algorithm.  相似文献

This article investigates the elasticity of different technology choices to energy efficiency and chemical oxygen demand/ammonia nitrogen emission reducing efficiency among 38 industries in China from 2008 to 2011. With data envelopment analysis, total-factor productivity growth, the common measure of technical progress, is divided into different parts: technical efficiency relative to the frontier, technology change and scale efficiency, which are regarded as three different choices of technological progress. For various industries, technology elasticity is quite different and the importance of different technical choices is diverse in the improvement of efficiency on energy saving and emission reduction. Policymakers could focus on the elasticity of different technical progress choices in various industries to improve energy and emission reduction efficiency.  相似文献

Aims: Adverse events (AEs) associated with treatments for metastatic colorectal cancer (mCRC) may compromise the course of treatment, impact quality-of-life, and increase healthcare resource utilization. This study assessed the direct healthcare costs of common AEs among mCRC patients in the US.

Methods: Adult mCRC patients treated with chemotherapy or targeted therapies were identified from administrative claims databases (2009–2014). Up to the first three mCRC treatment episodes per patient were considered and categorized as with or without the AE system/organ category during the episode. Total healthcare costs (2014 USD) were measured by treatment episode and reported on a monthly basis. Treatment episodes with the AE category were matched by treatment type and line of treatment to those without the AE category. Adjusted total cost differences were estimated by comparing costs during treatment episodes with vs without the AE category using multivariate regression models; p-values were estimated with bootstrap.

Results: A total of 4158 patients with ≥1 mCRC treatment episode were included (mean age?=?59 years; 58% male; 60% with liver and 14% with lung metastases; 2,261 [54%] with a second and 1,115 [27%] with a third episode). On average, two treatment episodes were observed per patient with an average length of 166 days per episode. Adjusted monthly total cost difference by AE category included hematologic ($1,480), respiratory ($1,253), endocrine/metabolic ($1,213), central nervous system (CNS; $1,136), and cardiovascular ($1,036; all p?Limitations: Claims do not include information on the cause of AEs, and potentially less severe AEs may not have been reported by the physician when billing the medical service. This study aimed to assess the association between costs and AEs and not the causation of AEs by treatment.

Conclusions: The most costly AEs among mCRC patients were hematologic, followed by respiratory, endocrine/metabolic, CNS, and cardiovascular.  相似文献

This study intended to discuss the interactive influence of the emergence, transformation and decline of the railway in Kaohsiung Port on urban development, the population, the activities and the economy in the region during the period of 1895–2010, from the perspectives of urban planning, railway development, population and industry. This study used the crossover analysis method, and used the factors of railway development and urban planning, within a fixed time period, to explore the chain dependence relationship among the industry, the population, the regional economy and the railway stations in Kaohsiung city. This study found that urban planning, economic development, railway development and industry have an interactive influence on the overall urban development. Urban planning promotes the rapid growth of the population, and economic development propels the growth and shaping of the regional economy, thus increasing employment opportunities. In addition, the railway development process moves forward with urban development.  相似文献

This paper examines the linkages between population growth and standard-of-living growth in 21 countries over the period of 1870–2013. We apply the bootstrap panel causality test proposed by Kónya (Econ Model 23:978–992, 2006), which accounts for both dependency and heterogeneity across countries. We find one-way Granger causality running from population growth to standard-of-living growth for Finland, France, Portugal, and Sweden, one-way Granger causality running from standard-of-living growth to population growth for Canada, Germany, Japan, Norway and Switzerland, two-way causality for Austria and Italy, and no causal relationship for Belgium, Brazil, Denmark, Netherlands, New Zealand, Spain, Sri Lanka, the UK, the USA, and Uruguay. Dividing the sample into two subsamples due to a structural break yields different results over the two periods of 1871–1951 and 1952–2013. Our empirical results suggest important policy implications for these 21 countries as the directions of causality differ across countries and time period.  相似文献

Using new estimates of ad valorem equivalent of nontariff measures (NTMs) over time, this paper examines NTMs and tariffs’ relationship for a sample of 70 economies for 4,949 products at the 6‐digit harmonized system level over the period 2003–2015. A panel data methodology models the lagged adjustment of NTMs to tariffs, consistent with a causal relationship. Trade policy substitution is found when the models are estimated in both levels and changes; with this holding for both OECD and non‐OECD countries, but not for the agriculture sector in OECD countries. Overall, there is a fairly complete substitution between policy instruments in absolute terms.  相似文献
