Information flows within and across sectors in Chinese stock markets   总被引:1,自引:0,他引:1  
We examine the patterns of information flows within and across sectors of the two Chinese stock exchanges in Shanghai and Shenzhen during 1994–2001. Using the generalized forecast error variance decomposition, we find a high degree of interdependence, indicating that the sectors are highly integrated and sector prices reflect information from other sectors. Industry is the most influential sector in both exchanges, while Finance in Shenzhen is the least integrated with other sectors. Implications of the findings for investors and policymakers are also discussed.  相似文献

This study examines whether individually held cultural values moderate the relationship between transformational leadership behavior of supervisors and the job involvement of subordinates in the Middle Eastern organizational context. Hierarchical regression analysis was used to analyze survey data from 229 employees of 10 organizations in the United Arab Emirates. In line with the findings of studies in Western countries, transformational leadership was found to influence job involvement positively. In addition, the cultural value orientations of individuals were found to moderate this relationship. Collectivism positively influenced the relationship between transformational leadership and job involvement, whereas uncertainty avoidance had a negative effect. These findings provide an insight into how transformational leadership may be used to motivate culturally diverse groups of employees within the Middle East. To enhance job involvement, organizations need to realize that the attitudinal response of subordinates to transformational leadership can depend on their cultural values. This has significant implications regarding the training and effective deployment of transformational leaders within Middle Eastern organizations.  相似文献

Informed by Institutional Theory, this study adopts an exploratory, qualitative, in-depth interviews-based approach as it explores the self-reported career paths of 32 women managers in Lebanon. The results indicate that in contrast with the majority of Western-based literature, the traditional-organizational career path in comparison to contemporary career patterns is still relevant, and continues to exist for Lebanese women managers as they progress in their managerial careers. At the same time, the findings suggest that women selectively adopt some aspects of contemporary, flexible careers to navigate their career paths amidst the macro-national economic and sociocultural factors and institutional challenges. The overall results and the implications for various stakeholders are further discussed in light of the related literature. This study suggests that scholars interested in women's careers in under-researched developing nations need to further integrate the agentic process – and the role played by women's individual agency in constructing their careers as they respond to institutional mandates – into their career models in more details. Similarly, multinational companies currently operating or interested in expanding their operations to the developing Arab Middle East region should incorporate these factors into their management and human resource practices.  相似文献

This paper focuses on the price determinants of gold, and on the challenges associated with gold’s safe haven property. Specifically, it analyses the interlinkages and the return spillover effect among gold, crude oil, S&P 500, dollar exchange rate, Consumer Price Index (CPI), economic policy uncertainty and Treasury bills, by employing a Vector Autoregression (VAR) and the spillover index of Diebold and Yilmaz (2012), Diebold and Yılmaz (2014). Monthly realized return series, covering the period from 2nd of January 1986 to 31st of December 2019 are used to examine the short-run linkages, and the return spillovers rolling-window estimates in analyzing the transmission mechanism in a time-varying fashion, respectively. Our findings identify gold as a strong dollar hedge, while crude oil and Treasury bills appear to drive inflation; they also indicate strong spillover effects between exchange rate and gold returns. In general, co-movement dynamics display state-dependent characteristics. Both total and directional spillovers increase significantly during market turbulence caused by severe financial crises such as the Global Financial Crisis (GFC) of 2007–2009 and the European Sovereign Debt Crisis of 2010–2012. Net spillovers switch between positive and negative values for all these markets, implying that the recipient/transmitter position changes drastically with market events. Economic policy uncertainty, stock market returns, and crude oil price returns are the main transmitters, while Treasury bills and CPI are the main return shock recipients. Gold and exchange rate act both as receivers and transmitters over the sample period.  相似文献

This study investigates the moderating role of gender and spousal working status on between work–family conflict (WFC)/family–work conflict (FWC) and affective commitment (AC). Based on 196 employees from a diverse range of industries in Hong Kong, a structural equation model is employed to examine the influences of WFC and FWC on AC. Multi‐group structural equation modelling and a t‐test analysis are used to examine whether such influences differ significantly by gender and spousal working group. Results indicate that negative effects of WFC and FWC on AC are stronger among employees with working spouses than non‐working spouses. Moreover, females have more negative perceptions of the relationship between WFC and AC than their males. Unexpectedly, the link between FWC and AC is found to be stronger among males than females. This study contributes to the human resource management literature by identifying circumstances that affect the influences of WFC and FWC on AC.  相似文献

The present study represents the first efforts to empirically examine the impact of mentoring on mentors’ work–family interface. Drawing on work–family enrichment theory, this study investigates the impact of mentorship quality perceived by mentors on their personal learning (i.e. relational job learning and personal skill development) and work–family interface (i.e. work–family conflict and work–family enrichment). Results from a two‐phase field survey of 117 mentors in China indicate that mentorship quality is positively associated with relational job learning but not personal skill development. Relational job learning was found to be positively related to work–family enrichment and negatively related to work–family conflict; it also mediates the relationships of mentorship quality with work–family conflict and work–family enrichment. Meanwhile, personal skill development positively relates to work–family enrichment, but does not relate to work–family conflict. These findings provide evidence that mentoring is beneficial for mentors’ family lives, thereby encouraging senior employees to become mentors.  相似文献

Past research on the effects of employees' use of work–family support policies tends to draw on a depletion perspective suggesting that using these policies may reduce work–family conflict. The emphasis on depletion fails to consider the expansion perspective that assumes that using work resources may enrich family functioning. Using a sample of 113 matched employee–supervisor pairs and a 1‐month separation between predictor and criterion measurement, we found support for the expansion rather than the depletion perspective. Specifically, the relationships between support policy use and employee job satisfaction and family efficacy (but not organisational citizenship behaviour) were mediated by work‐to‐family enrichment; these effects were realised only for employees with high levels of family identity. In contrast, no support was found for family‐to‐work conflict as a mediator of the model.  相似文献

This article explores the localized experiences of women at work in higher education in the under-researched context of the Arab Middle East and North Africa. Our main research questions are: What is the current status of academic women between and across the countries of this region? How can human resources play a developmental role for women at work in academic institutions, as well as for the region in general? We adopt a two-part research method in this study. First, through a critical review of the literature, we develop a regionally relevant macrolevel hypothetical model to localize a gender perspective on women at work. Second, we engage in a focused empirical examination of publicly available university data to document the: (1) representation of women across ranks; and (2) specific content of pertinent human resource policies. On the basis of these data, we propose a more complete multilevel hypothetical model upon which we put forward a critical discussion and directions for future research on gender, human resource management and regional development more broadly.  相似文献

The Lee–Carter method for modeling and forecasting mortality has been shown to work quite well given long time series of data. Here we consider how it can be used when there are few observations at uneven intervals. Assuming that the underlying model is correct and that the mortality index follows a random walk with drift, we find the method can be used with sparse data. The central forecast depends mainly on the first and last observation, and so can be generated with just two observations, preferably not too close in time. With three data points, uncertainty can also be estimated, although such estimates of uncertainty are themselves highly uncertain and improve with additional observations. We apply the methods to China and South Korea, which have 3 and 20 data points, respectively, at uneven intervals.  相似文献

This paper presents stories from women who work and care for a child with a significant chronic illness or disability. The purpose of this paper is to move towards ending the silence on their lives. A three-phase emergent research design responds to the question: What is life like for a full-time worker who is concurrently the primary carer of a chronically ill child? This paper considers the theory of Silencing the Self (Jack, 1991) in relation to the emergent themes of “Otherness” and “Doing it All.” As in Jack’s study, these women also engaged in silencing of the self. However, unlike the respondents in Jack’s study, these women did not demonstrate feelings of worthlessness and hopelessness for the future, nor were they alone in contributing to their silence. Indeed, many experienced silencing behaviors from others around them, and many rallied against the silence, not accepting that their burden should continue. Consideration of Jack’s theory is made to point out the distinctions between the women in this study and Jack’s study, and analytical commentary is provided to demonstrate the relevance of this analysis in light of the current debates surrounding the Work–Home Conflict and the rising levels of informal care provided by women in our communities.  相似文献

There is some debate whether job strain or working hours is more prominent in explaining work–family conflict. We tested a multi‐group structural equation model and the results suggested the model was equally applicable to academic and administrative staff employed at an Australian regional university. After controlling for demographic and work‐related factors the main predictors of work–family conflict were: job strain, total work hours, job satisfaction, employment as an academic and having dependent children. Social support was negatively related with work–family conflict but the association was not significant. Despite greater job control, academics reported greater job strain and work hours. The results suggest that strategies aimed at decreasing job strain and work hours may reduce the extent of work–family conflict.  相似文献

This paper investigates and reports on the extent and nature of corporate internet disclosure and the determinants of internet financial disclosure (IFD) by companies listed in three Gulf Corporation Council (GCC) countries. This paper uses data from 207 listed companies in Muscat Securities Market (MSM), Dubai Financial Market (DFM), and Qatar Exchange (QE). Binary logistic regression analysis is used to examine the determinants of IFD. Kruskal-Wallis test is used to examine the differences in disclosure characteristics among the three countries. The results of this study reveal that firm size is the major factor influencing intemet financial reporting in the GCC. The results reveal that the three countries differ significantly in all the disclosure attributes with the exception of the existence of email link. This paper extends the stream of research that confirms the widespread use of internet in disclosing financial information. The results are consistent with previous literature that corporate size is a major determinant of internet financial reporting. This paper provides insights into corporate internet disclosure in the GCC that will benefit all stakeholders with an interest in corporate reporting in this important region of the world.  相似文献

In this article we propose to exploit topological information embedded in forecast error variance decomposition derived from large Bayesian vector autoregressive models (VAR) to study network connectedness and risk transmission of multivariate time series observations. Firstly, we design a robust link classification procedure based on shortest paths, so to identify salient directional spillovers in a high-dimensional framework. Secondly, we study recurrent and statistically significant sub-graphs, i.e. network motifs, on the induced network backbone by means of null models which account for local node heterogeneity. The methodology is applied to analyze spillover networks of a set of global commodity prices. We demonstrate that spillovers become key drivers of the system variance during commodity price bubbles and bursts, giving raise to complex triadic structures which do not manifest during normal business periods. By accounting for local node connectivity, we observe a departure from the null models due to the high participation of Crude Oil, Food and Beverages and Raw Materials in complex recurrent sub-graphs.  相似文献

The purpose of this study is to examine the relationship between high‐performance work systems (HPWS) and the work–family interface (i.e. work–family conflict (WFC) and work–family facilitation (WFF)) in a Chinese context. We used job autonomy and self‐efficacy as an underlying mechanism for describing the relationship between HPWS and the work–family interface. Using data from 152 HR managers and 1324 employees, we found that the HPWS was positively associated with both job autonomy and self‐efficacy. We observed that self‐efficacy was an important mechanism to explain the relationship between HPWS and WFF and WFC. We also observed that job autonomy mediated the relationship between HPWS and WFF, but its presence was not significant between HPWS and WFC. One unique contribution of the study is that the authors extended the job demands–resources model to Chinese employees, confirming that self‐efficacy is an important mechanism linking HPWS with WFC and WFF. Practical implications and future research directions are discussed.  相似文献

This study investigated work–life interaction across the life course within one industry sector, healthcare. This workforce closely mirrors larger labour force trends such as women's increasing participation in paid work, an ageing workforce and working carers of children and elders. This qualitative study of 105 health professionals provides insight into the work–life challenges and needs of a modern diverse workforce, including the policies and practices that are likely to maximise employee well‐being and retention. Indeed, significant differences in work–life perspectives and needs were observed with workers at different life stages. Similarities were also apparent, particularly with regard to work demands and flexibility. It was clear that existing organisational policies (and culture) do not meet the needs of workers across the life course, and led to reduced work hours and turnover intentions. Implications for organisational policies and practices are discussed, with a focus on access to part‐time and flexible work.  相似文献

We develop a technique to exploit forecast error variance decompositions to evaluate the macroeconomic connectedness embedded in any multi-country macroeconomic model with an approximate vector autoregressive (VAR) representation. We apply our technique to a large global VAR model covering 25 countries and derive vivid representations of macroeconomic connectedness. We find that the US exerts a dominant influence in the global economy and that Brazil, China, and the Eurozone are also globally significant. Recursive analysis over the period of the global financial crisis shows that shocks to global equity markets are transmitted rapidly and forcefully to real trade flows and real GDP.  相似文献

Previous research on the relationship between work hours and health has produced inconclusive findings, which may be related to the use of predominantly male samples. This paper examines the relationship between work hours and health in a national Australian sample (Australian Work + Life Index) of men and women. We examine total work hours across major occupational groups and find differences in health outcomes related to gender. In addition, our findings provide important insights into the pathway through which work hours impact health. Specifically, we offer compelling evidence that work–life conflict functions as a pathway through which total work hours impact health outcomes. The results of this study suggest that human resource management practitioners pay further attention to interventions that enable workers to more successfully manage the energy exchange between work and non‐work domains. We also review several related pathways by which human resource managers may reduce employee work–life conflict.  相似文献

In this paper, Bayesian estimation of log odds ratios over R × C and 2 × 2 × K contingency tables is considered, which is practically reasonable in the presence of prior information. Likelihood functions for log odds ratios are derived for each table structure. A prior specification strategy is proposed. Posterior inferences are drawn using Gibbs sampling and Metropolis–Hastings algorithm. Two numerical examples are given to illustrate the matters argued.  相似文献
