The twenty-first century has seen an increase in ethical misconduct at the workplace, highlighting the need to stimulate discussion on the role of work ethics. The objective of the current study is to extend the literature on work ethics by examining the role of Islamic work ethic in enhancing the task performance of employees. The current study proposes that psychological capital mediates the relationship between Islamic work ethic and task performance. It is also proposed that ethical leadership might act as a boundary condition that boosts the positive relationship between Islamic work ethic and psychological capital. Data were collected in three-time lags from employees working in the service sector of Pakistan (N?=?218) through the questionnaire. The results supported the mediation and moderation hypothesis, confirming that psychological capital mediates the relationship between Islamic work ethic and task performance. Ethical leadership moderates the relationship between Islamic work ethic and psychological capital. The results offer implications for theory and practice. Limitations and future research directions are also discussed.

The question of public debt management for both developed and developing economies has generated an enormous amount of political as well as academic interest. This study examines how governance affects public debt accumulation in the MENA countries during the 1996–2015 period. The six Worldwide Governance indicators (voice and accountability, political stability and the absence of violence/terrorism, government effectiveness, regulatory quality, rule of law and control of corruption) were used to measure the quality of governance in these countries. The results show that only three governance indicators support well the hypothesis that poor governance leads to higher accumulation of MENA public debt. Moreover, the estimates suggest a significant indirect impact of bad governance operating via decreased GDP growth. These findings have important implications for policy makers of these countries, which are currently facing major fiscal and external imbalances due to the high cost of war and terrorist attacks, low oil prices and a decline in trade. Sound public debt management represents an urgent task especially that public debt management problems often find their origins in the lack of attention paid by policymakers to the costs of bad governance and weak macroeconomic management.  相似文献

There has been large-scale growth in Islamic finance and banking in Muslim countries and around the world during the last twenty years. This growth is influenced by factors including the introduction of broad macroeconomic and structural reforms in financial systems, the liberalization of capital movements, privatization, the global integration of financial markets, and the introduction of innovative and new Islamic products. Islamic finance is now reaching new levels of sophistication. However, a complete Islamic financial system with its identifiable instruments and markets is still very much at an early stage of evolution. Many problems and challenges relating to Islamic instruments, financial markets, and regulations must be addressed and resolved. In this paper, we provide a comprehensive comparative review of the literature on the Islamic financial system. Specifically, we discuss the basic features of the Islamic finance and banking. We also introduce Islamic financial instruments in order to compare them to existing Western financial instruments and discuss the legal problems that investors in these instruments may encounter. The paper also gives a preliminary empirical assessment of the performance of Islamic banking and finance, and highlights the regulations, challenges and problems in the Islamic banking market.  相似文献

Economic sanctions are an important instrument of U.S. foreign policy. While politicians look favorably on unilateral economic sanctions as a policy instrument, many scholars attribute significant long-term economic costs to the United States and have doubts about their effectiveness. We outline a simple approach to assess the vulnerability of target countries to sanctions in order to develop focused sanctions and reduce unnecessary costs to U.S. business, avoid the imposition of sanctions on countries when sanctions are unlikely to have the desired effects, and determine what other countries must join the United States in imposing sanctions if they are to be effective.JEL Classification K330,F190  相似文献

Umbrella branding (UB) strategies for manufacturers’ products have received considerable attention in the literature. Not much is known about this strategy for private labels. Using a game-theoretic approach, we reassess the benefits of introducing a private label in a distinct category, and provide favorable conditions for the retailer to implement umbrella or individual branding for his private labels. We find that (1) UB leads to lower wholesale and retail prices for both national brands; (2) national brands’ manufacturers prefer individual branding over UB for private labels; and (3) the profitability of UB is not always guaranteed for the retailer.  相似文献

It has been realized that none of the three basic theories of capital structure presents a complete answer to the actual determinants of corporate financing decisions. This study attempts to model the practice of capital structure decisions according to the basic premises of each theory of capital structure: trade-off theory, pecking-order theory and free cash flow theory. The methodology addresses modeling long-term and short-term debt financing decisions based on ten different statistical criteria using data from Egypt stock market. The empirical evidence indicates that four models of corporate financing are influenced by the trade-off theory relatively. The contributions of this paper are as follows. First, this study offers a more refined and comprehensive methodology for modeling firms’ capital structure decisions. Second, the results of this study compare to those of previous studies of other developing countries and thus add an element of external validity. Mohamed A. Ismail is currently working as a consultant for the Information and Decision Support Center (IDSC), the Egyptian Cabinet-Egypt. He would like to acknowledge the financial support provided by the IDSC.  相似文献

Transaction cost economics and its uses in marketing   总被引:1,自引:0,他引:1  
Scholarship at the intersection of transaction cost economics (TCE) and marketing has enjoyed an impressive record of growth over the past three decades, and the future promises more of the same. Following Erin Anderson’s perceptive uses of TCE in her 1982 dissertation, the field of marketing has made many constructive uses of and contributions to TCE, where the latter include broadening the reach of TCE, posing important challenges, and identifying opportunities still to be addressed. Given this history, we advance the proposition that the relation between TCE and marketing has been and should be a two-way street. In considering the scope for future research, we give special attention to issues of asymmetric costs, the dynamics of governance, and disequilibrium contracting. We also discuss the four precepts of pragmatic methodology, with special emphasis on prediction and empirical testing. The Appendix provides added perspective on the evolving “science of organization” of which TCE is a part.  相似文献

Exploring multiple dimensions of management control systems (MCS), this article proposes a new framework to integrate risk management with strategy, MCS and performance measurement systems (PMS). Considering the public sector as a focal point, the article points to some enterprise risk management (ERM) issues and argues that ERM-enabled MCS has potential to improve PMS and strategic decision-making, leading to a more proactive risk management framework and a culture that promotes performance driven accountability. Consequently, the article calls for further research towards solving the public sector’s risk management problems, motivating its managers to adopt best practices, and stimulating suitable policy developments.  相似文献

Interdisciplinary research on measuring the progress towards sustainability and well-being (SaW) from different perspectives and in various contexts has developed dramatically over recent decades. This growth in the literature has not only added an enormous number of dimensions to the SaW debate, but the sheer scale of the expansion has challenged researchers to be able to conduct a comprehensive analysis of the available SaW indicators. In this work, we have proposed a hybrid method comprised of sophisticated scientometric analysis to summarise scientific developments in the massive text corpus of the SaW literature in conjunction with a more traditional literature review to categorise the ‘fuzzy’ details that remain. Scientometric analysis highlights that the developed OECD countries play a vital role in the development and applications of SaW indicators and we describe key developments in this regard via a range of graphical approaches. Using an extensive collection of existing SaW indicators, the analysis is then summarised in a matrix of ranked indicators which serve as a powerful tool to compare, contrast, filter and select indicators for SaW assessment with minimum redundancies between indicators. The approach undertaken in this study is intended to be flexible and can be extended and applied to other fields of research.  相似文献

This article reports on the results from an ongoing research program to study the role mental models play in project decision making. Project management belongs to the class of multiloop nonlinear feedback systems, but most managers do not see it that way. Our experimental results suggest that managers adopt simplistic single‐loop views of causality, ignore multiple feedback interactions, and are insensitive to nonlinearities. Specifically, the article examines single‐loop models of project planning and control, discusses their limitations, and proposes tools to address them.  相似文献
