The relaxation of security laws and regulations in emerging markets in the Middle East and North Africa (MENA) provides abundant opportunities for foreign investors. These markets exhibit high-expected returns and substantial volatility. In this paper, we investigate the lead/lag relationship between the MENA countries and regions. We find no market causality or spillover from one country to another in the North Africa region. Our results for the Levant region reveal that there are linkages between stock markets in this region. The results for the Gulf Cooperation Council (GCC) region show that there is more interaction and linkage in the GCC region than in the North Africa and Levant regions. An unexpected result is that UAE's stock market leads all the markets in this region. Finally, we investigate linkages among the three regions. We find that GCC influences the other two regions.  相似文献

The effectiveness of the decision‐making process in appraisal has been of long‐standing interest. This paper reports the results of research exploring the extent to which those undertaking appraisals apply systematic processes to their decision‐making, represented in terms of the cognitive processing models applied by appraisers. Results of 22 cognitive mapping interviews exploring appraisal practice, undertaken with appraisers in the Malaysian education system, are described. The resultant cognitive maps have been explored for what they tell us about the cognitive processing models underlying appraisers' decision‐making. Results suggest that the practice of appraisal evidenced in interviews demonstrates the presence of cognitive processing that reflects theoretical cognitive processing models, although some differences are observed between less experienced and experienced appraisers' models. Implications from the interview findings for the practice of appraisal are identified.  相似文献

Fifty years of Pakistan history are characterized by two major issues: first, ideological, ie the role of Islamic politico-social ideals and the processes for their implementation, and the challenge to them from the forces of secularism; and second, the clash and conflict between the forces of democracy and despotism. These two areas have mostly been examined in the literature as distinct and somewhat autonomous conflicts. The fact is that in the Muslim context they represent two sides of the same coin. The author argues that democratization is a stepping stone in Islamization and fulfilment of Islamic aspirations is possible only through promotion of democratic processes.  相似文献

ABSTRACT

This paper contributes to the productivity literature by demonstrating novel econometric methods to estimate input-mix efficiency (IME) in a parametric framework. Input-mix efficiency is defined as the potential improvement in productivity with change in input mix. Any change in input-mix (e.g., land to labou r ratio) will result in change in productivity. The advantage of this approach is that it does not require data on input prices to estimate the mix efficiency levels. A nonlinear input-aggregator function (e.g., Constant Elasticity of Substitution) is used to derive an expression for input-mix efficiency. Bayesian stochastic frontier is estimated for obtaining mix efficiency using US state-level agricultural data for the period 1960–2004. Significant variation in input-mix efficiency is noted across the states and regions, attributable to diverse topographic and geographic conditions. Furthermore, comparisons of allocative and mix efficiencies provide insightful policy implications. The production incentives such as taxes and subsidies could help farmers in adjusting their input mix in response to changes in input prices, which can affect the US agricultural productivity significantly. The proposed methodology can be extended by i) using flexible functional forms; ii) introducing various time- and region-varying input aggregators; and iii) defining more sophisticated weights for input aggregators.  相似文献

This study aims to investigate the relationship between China's exchange rate, foreign direct investment (FDI) inflows, and economic development. We applied the bound testing approach on aggregate level data from 1981 to 2013. The results showed that the Chinese economy benefitted from a lower exchange rate over this period, and that there was a direct link between FDI inflows and economic development on an aggregate level both in the long and short run. The results of the Granger causality test identified a long‐ and short‐run association among these variables. The GMM estimations with dummies for financial crises and RMB exchange rate policy fluctuations also confirmed the growth enhancing impact of the exchange rate and FDI inflows. To promote sustainable economic development in the future, China should focus on improving the levels of domestic investment and human capital, as well as supervising the level of openness and capital controls.  相似文献

In this study, we assessed the epidemiological patterns of suicide terrorism in the civilian population of Pakistan. Information about suicide terrorism-related events, deaths and injuries was extracted from the South-Asian Terrorism Portal (SATP) for the period from 2002 to October 2009. Of 198 events, civilians were involved in 194 events. Civilians accounted for 74.1% (N?=?2017) of those who died and 93.8% (N?=?6129) of those who were injured. In nine districts, mortality rates were more than one death per 100,000 inhabitants per year. The yearly trend showed a shift of attack targets from foreigners and sectarian targets in 2002-2005 to security forces or general public in 2006-2009. Attacks on public installations (mosques) or political gatherings resulted in a significantly greater (P?≤?0.02) number of deaths (22 vs. 8) and injuries (59 vs. 24) per event compared with security installations. These results show that prevention might focus on political negotiation with armed groups and that appropriate measures should be taken to protect mosques and political gatherings.  相似文献

This study attempts to explain the influence of personal and hotel factors on the expectation level of hotel hospitality as well as to propose a scale to measure commercial hospitality for hotel services. A total of 101 local and international hotel guests were involved in the study. The results revealed that the expectations of hotel hospitality are influenced by personal factors such as gender, purpose of stay, nationality, and private domain of hospitality. The hotel's star rating is the only hotel factor that might have strong association with hotel hospitality.  相似文献

We examine the firm‐specific determinants of technical efficiency in Australian mining companies using data envelopment analysis (DEA). To do so, we employ panel data sourced from individual mining companies listed on the Australian Securities Exchange (ASX) over the period 2010–2014. To ensure valid statistical inference in the presence of serial correlation between DEA efficiency scores, we apply Simar and Wilson's two‐stage bootstrap method. We find that ownership concentration, firm size, firm age, product portfolio, product diversification and growth status significantly contribute to efficiency gains. However, other firm‐specific factors, such as capacity utilisation, financial risk and overseas operations appear to have limited impact on the technical efficiency of mining firms.  相似文献

Humans are unable to effectively handle machines that have poor interface and interaction patterns. The Automated Teller Machine (ATM) is one of the machines that is most frequently operated by a wide spectrum of people. Hence, it is common to apply Human–Computer Interaction (HCI) technology in the design of ATMs. User–ATM interaction, however, has barriers such as a user’s working memory limit, lower literacy level, or lack of awareness and access. Moreover, the diversity of interfaces hurt user motivation, perception, and experience significantly. For example, each bank has its own ATM design targeting its customers only and, thus, when clients of other banks come across such a machine, they suffer from cognitive burden and commit many errors. To this end, we conduct an analytical survey of ATMs used in Pakistan through user analysis and heuristics analysis. We figure out the influence of design diversity and user perception on ATM users’ cognitive stress with the cognitive walkthrough analysis on the survey. We also uncover a realism-usability gap by reviewing the sampled ATM screens from the viewpoint of HCI heuristics. Finally, we suggest the guidelines on the cross-ATM design, characterized by the standardized fast-cash menu and the fail-safe mechanism for novices. This study demonstrates that users are reluctant to switch out of their comfort zones, due to learning costs and a lack of motivation. Therefore, we should design public systems in a very standardized way, which becomes more crucial for a user’s cognitive relief as interface and design patterns are becoming more diverse in our daily lives.  相似文献
