We study how natural resource rents affect the risk of internal conflict within countries and how the federal structure of countries influences this relationship. Natural resource abundance may induce excessive rent-seeking and thus increase the risk of internal conflict. Fiscal and political decentralization as an institutional arrangement for rent-sharing and political codetermination of regions within a country may limit the destructive effect of natural resource rents on internal stability. Using cross-country and panel data from more than 90 countries covering the period 1984–2004, we find evidence that natural resource rents indeed increase the risk of internal conflict, but this relationship is significantly mitigated by political decentralization.  相似文献

Despite extensive literature on green hotel management and sustainability, scant attention has been given on the role of managers to solve environmental related issues. This study's aim is to assess the effects of managers' green knowledge and green transformational leadership on firms' environmental performance with the mediating effect of green creativity. The study analyzes the perceptions of 363 employees in different managerial positions of the hotel industry employing Partial Last Square Structural Equation Modeling. The findings of the study show a positive effect of green knowledge and green transformational leadership on green creativity and green transformational leadership on environmental performance. Furthermore, green creativity is also found to have significant mediating effect between green knowledge and environmental performance, and green transformational leadership and environmental performance relations. The main implication of the current research is that managers' green concerns might help the stakeholders in the hotel industry to respond through appropriate green initiatives for their organizations. Further suggestions for literature and practice are discussed.  相似文献

ABSTRACT

The success of small and medium-sized enterprises (SMEs) depends on dynamic capabilities, as it provides opportunities to remain competitive and perform well in the dynamic business environment. Although several studies show the significant positive impacts of dynamic capabilities on firm performance, our knowledge of the underlying mechanism through which IT capabilities affect the firm performance is not yet clear. Applying the dynamic capability view, this study investigates the intervening role of absorptive capacity and corporate entrepreneurship. The data of 417 respondents is collected from medium-sized manufacturing sector SMEs in Punjab, Pakistan. The research hypotheses have been analysed through the structural equation modelling method by using the Smart-PLS software. The research findings show that absorptive capacity and corporate entrepreneurship partially mediates the relationship between IT capabilities and firm performance. Furthermore, the sequential path of IT technical skills, absorptive capacity, corporate entrepreneurship, and firm performance is highly significant as compared to other paths.  相似文献

This study aimed to identify the roles of laypeople at road traffic injuries (RTIs). A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The key words of ‘laypeople’, ‘layman’, ‘layperson’, ‘bystander’, ‘first responder’, ‘lay first responder’, ‘road traffic’, ‘road traffic injury’, ‘crash injury’, ‘crash scene’, ‘emergency’, ‘trauma care’, and ‘prehospital trauma care’ were used in combination with the Boolean operators OR and AND. We did electronic search on Google Scholar, PubMed, ISI Web of Science, CINAHL, Science Direct, Scopus, ProQuest. Based on the reviewed studies, some factors such as cultural conditions, knowledge, relief agencies, and demographic factors affect the interventions of laypeople at the crash scene in functional areas. Regarding the permanent presence of people at the crash scene, the present study can provide an opportunity to reduce different side effects of RTIs imposed on the society.  相似文献

The purpose of this paper is to present a closed formula to compute the moments of a general function from the knowledge of its bivariate survival function. The result is derived by utilizing an integration by parts formula for two variables, which is not readily available in the literature. Many of the existing results are obtained as special cases. Finally, two examples are presented to illustrate the results. In both the examples, mixed moments as well as moments for the series system and parallel system are obtained. The integration by parts formula in two variables, derived here, is of interest in its own right and we hope that it will be useful in other investigations. The integration by parts formula in two variables is derived as a special case of a general formula in n variables.  相似文献

We study the intertemporal risk‐return tradeoff relations based on returns from 18 international markets. We find striking new empirical evidence that the inclusion of U.S. market returns significantly changes the estimated risk‐return tradeoff relations in international markets from mostly negative to predominantly positive. Our results are consistent with the lead‐lag effect between U.S. and international markets in the sense of Rapach, Strauss and Zhou.  相似文献

This paper examines the effect of various types of bank capital on the profitability and efficiency of conventional and Islamic banks. Our results show that higher quality forms of capital improve the profitability and efficiency for both systems although the results are stronger for conventional banks. The capital effect is more pronounced for large, too-big-to-fail, and highly capitalized banks. The results are robust across various subsamples, alternative profitability and efficiency measures, and different estimation techniques.  相似文献

Financial services institutions often provide special introductory prices to new customers who sign up for their services such as credit cards, credit monitoring services and online stock trading. Despite their prevalence, the decision to provide introductory prices to new customers entails challenges for decision makers. Providing small incentives may not perceptibly affect the adoption of the service while providing a large incentive leads to the loss of revenue and profits. As a result, the effectiveness of such activities on firm profitability remains largely unexplored. This study seeks to address this gap in the literature by exploring optimal introductory pricing of a financial service. Employing agent-based simulation experiments, we find that offering introductory discounts significantly increases a firm’s net present value (NPV) of profits. Moreover, the findings suggest the amount of discount and the duration of time that a new customer receives the discount are critical factors in determining the NPV of profits. The research and managerial implications are discussed.  相似文献

The aim in this article is to measure the scale efficiency of the New Zealand dairy industry and to examine the relationship between farm size and technical efficiency. Data envelopment analysis (DEA) is applied to a sample of 264 dairy farms. The results suggest that 19 per cent of these farms are operating at optimal scale, 28 per cent at above optimal scale, and 53 per cent at below optimal scale. On average, the optimal size for New Zealand dairy farms is estimated at 83 hectares with a herd of 260 animals. Average technical efficiency is estimated at 89 per cent.  相似文献
