This study examines whether the diversity of activities conducted by the banking sector in the years approaching the recent global financial crisis alleviated the adverse impact of the crisis. Using data for 28 industries in 66 countries, we find that bank diversification has strengthened country resilience to the crisis, as measured by industry growth over the period 2008–2009. However, we find that while both bank‐based and market‐based economies have been affected negatively by the crisis, the contribution of bank diversification in mitigating the real impact of the crisis is pronounced only in bank‐based economies. Overall, our findings suggest that countries with significant bank diversification have also been the most resilient to the recent global crisis. 相似文献

Although a growing body of research has shown the positive impact of ethical leadership on workplace deviance, questions remain as to whether its benefits are consistent across all situations. In this investigation, we explore an important boundary condition of ethical leadership by exploring how employees’ moral awareness may lessen the need for ethical leadership. Drawing on substitutes for leadership theory, we suggest that when individuals already possess a heightened level of moral awareness, ethical leadership’s role in reducing deviant actions may be reduced. However, when individuals lack this strong moral disposition, ethical leadership may be instrumental in inspiring them to reduce their deviant actions. To enhance the external validity and generalizability of our findings, the current research used two large field samples of working professionals in both Turkey and the USA. Results suggest that ethical leadership’s positive influence on workplace deviance is dependent upon the individual’s moral awareness—helpful for those employees whose moral awareness is low, but not high. Thus, our investigation helps to build theory around the contingencies of ethical leadership and the specific audience for whom it may be more (or less) influential. 相似文献

The Growing Relationship Between China and Sub-Saharan Africa: Macroeconomic, Trade, Investment, and Aid Links 总被引:2,自引:0,他引:2
China's economic ascendance over the past two decades has generatedripple effects in the world economy. Its search for naturalresources to satisfy the demands of industrialization has ledit to Sub-Saharan Africa. Trade between China and Africa in2006 totaled more than $50 billion, with Chinese companies importingoil from Angola and Sudan, timber from Central Africa, and copperfrom Zambia. Demand from China has contributed to an upwardswing in prices, particularly for oil and metals from Africa,and has given a boost to real GDP in Sub-Saharan Africa. Chineseaid and investment in infrastructure are bringing desperatelyneeded capital to the continent. At the same time, however,strong Chinese demand for oil is contributing to an increasein the import bill for many oil-importing Sub-Saharan Africancountries, and its exports of low-cost textiles, while benefitingAfrican consumers, is threatening to displace local production.China poses a challenge to good governance and macroeconomicmanagement in Africa because of the potential Dutch diseaseimplications of commodity booms. China presents both an opportunityfor Africa to reduce its marginalization from the global economyand a challenge for it to effectively harness the influx ofresources to promote poverty-reducing economic development athome.

Recent theoretical literature on the sources of economic growth has emphasized the role of human capital as an internal contributing force in the growth process. Empirical results reported in this paper provide support for this theoretical proposition. Cross-country data from 32 developing countries indicate that human capital (as alternatively measured by the primary school enrollment rate or the adult literacy rate) exerts a significant positive impact upon output growth. 相似文献

Impact of formalisation of property rights in informal settlements: Evidence from Dar es Salaam city
This paper aims to study the responsiveness of the informal property market and management systems towards the introduction of land registration for informal settlements in Tanzania. City governments are increasingly recognising the need to strengthen legal rights for the urban poor as a means to bring them more effectively into the urban economy and ensure better provision of water, sanitation and other primary services. The research focuses on Tanzania and in particular two case studies within Dar es Salaam. The findings of the work suggest that the introduction of residential licenses whilst potentially assisting in creating legal certainty has not resulted in the financial sector accepting them as full security against loans. Accessing credit by the poor however has not yet been fully realised resulting in some further hurdles for the financial sector to overcome. Finally, and of some significance is the registration of property in the informal settlements has provided the opportunity of formal property transactions within these settlements. 相似文献

Security of Big Data is a huge concern. In a broad sense, Big Data contains two types of data: structured and unstructured. Providing security to unstructured data is more difficult than providing security to structured data. In this paper, we have developed an approach to provide adequate security to unstructured data by considering types of data and their sensitivity levels. We have reviewed the different analytics methods of Big Data to build nodes of different types of data. Each type of data has been classified to provide adequate security and enhance the overhead of the security system. To provide security to a data node, and a security suite has been designed by incorporating different security algorithms. Those security algorithms collectively form a security suite which has been interfaced with the data node. Information on data sensitivity has been collected through a survey. We have shown through several experiments on multiple computer systems with varied configurations that data classification with respect to sensitivity levels enhances the performance of the system. The experimental results show how and in what amount the designed security suite reduces overhead and increases security simultaneously. 相似文献

This study assesses the direct influence of food quality and e-service quality on customer loyalty toward online food delivery (OFD) service and its indirect influence through the mediation of customer satisfaction and perceived value. This study uses a survey of 405 OFD service customers from Bandung, Indonesia. By applying variance-based partial least squares to evaluate the proposed model, this study confirms the direct effect of food quality on online loyalty, but not e-service quality. Further, this study discloses the partial mediation role of customer satisfaction and perceived value on the relationship between both food quality and e-service quality on online loyalty toward OFD services. 相似文献

We examine the choice between accelerated share repurchase (ASR) and open market repurchase (OMR) as repurchase mechanisms between 2004 and 2007. For a sample of ASRs and OMRs that actually buy shares in the announcement quarter, we find that ASR firms have lower market‐to‐book ratios, less cash, but greater managerial entrenchment. Prior to repurchase, ASR firms are subject to significantly more takeover rumors than OMR firms are, and this, along with entrenchment and undervaluation, affects the choice to use ASRs. ASR firms experience positive average abnormal returns both before and after the announcement. Moreover, the latent takeover probability is significantly lower for both ASR and OMR firms (when compared with pre‐announcement levels), but the reduction for ASR firms is more pronounced. Our results suggest that repurchases, and especially ASRs, indeed make a firm a less attractive prospect for takeover. 相似文献

We present a theoretical methodology for the pricing of catastrophe (CAT) derivatives with event‐dependent and non‐convex payoffs given the price of a CAT indexed futures contract. We do not assume a fully diversifiable CAT event risk, nor do we assume knowledge of the martingale probability measure beyond the futures price. We derive tight bounds on the contract value and present trading strategies exploiting the mispricing whenever the bounds are violated. We estimate the bounds of the reinsurance contract with data from hurricane landings in Florida. Our method is also applicable when there is no futures market but the price of a CAT‐indexed bond is available. 相似文献

Over the last 15 years, high trade deficits have become a source of external vulnerability for the relatively stabilized Turkish economy. This corresponds to the period where authorities have been following a floating exchange rate regime. Thus, this study aims to empirically show whether the adopted exchange rate regime has an impact on the trade balance for the period of 1987 Q1 to 2015 Q2. Estimation results indicate that there is a long-run relationship between the real effective exchange rate and trade balance under both fixed and floating regimes in Turkey, but there is no evidence for the J-curve hypothesis. 相似文献
