为改善重大水利工程项目决策社会稳定风险评估中公众参与现状,从社会稳定风险评估3个主要利益主体——中央政府、地方政府与公众不同的利益诉求出发,运用演化博弈模型,探讨在不同利益诉求的相互作用下影响地方政府与公众在社会稳定风险评估中策略选择的因素。研究发现,当公众受到的损失大于参与付出的成本时,双方稳定均衡状态均表现积极,反之,双方可能均表现为消极或积极这两种截然不同的状态。基于此,分析了中央政府对地方政府和公众在社会稳定风险评估博弈中策略选择的影响。最后,提出应加大对地方政府的支持、规范公众参与相关制度、加大教育培训及宣传力度、创新公众参与方式几项政策建议。 相似文献

With unique daily short sale data of Borsa Istanbul (stock exchange of Turkey), we investigate the dynamic relationship between short selling activity and volatility, liquidity and market return from January 2005 to December 2012 using a VAR(p)-cDCC-FIEGARCH(1,d,1) approach. Our findings suggest that short sellers are contrarian traders and contribute to efficient stock market in Turkey. We also show that increased short selling activity is associated with higher liquidity and decreased volatility. However this relation weakens during the financial turmoil of 2008. Our results indicate that any ban on short sales may be detrimental for financial stability and market quality in Turkey. 相似文献

This study examines the relationship between airline travellers' casual attribution, pre-recovery emotions, and negative behavioural intentions after a service failure and proposes a model for analysing direct effects of airline travellers' casual attribution of stability (failure frequency) and controllability (the extent to which the airline can control the failure) on negative behavioural intentions as well as its indirect effects through pre-recovery emotions. Data were gathered through a survey of airline travellers who experienced a failure in the past six months. The results indicate that both dimensions of casual attribution influenced pre-recovery emotions and negative behavioural intentions, and that pre-recovery emotions were significantly related to negative behavioural intentions. In addition, the results verify the mediating effect of pre-recovery emotions on the relationship between casual attribution and behavioural intentions. These results have important managerial implications. 相似文献

The study examined banking stability in Sub-Saharan Africa. The results reveal that banking spread (Net Interest Margin – NIM) is the main determinant of stability and the major means to achieve stability during crises periods. We however find the existence of a threshold effect in NIM.Crises in the banking sector consistently showed to reduce stability. While the results show that high percentage of foreign banks reduce stability, we find foreign banks help stabilize the banking sector in periods of crises. The results show that diversification could also have a positive impact on stability (Z-score) even though this relationship was not robust enough. The results also largely support the competition-fragility view. Particularly, we find that less competition during crises periods can help improve stability. Again, we find evidence for both concentration-stability and concentration-fragility hypotheses depending on the stability measure used. We however find that when large banks in concentrated markets are well regulated, stability could be improved. Weak regulatory environment reduces stability (Z-score) directly and matters during crises periods. Our results are robust to the use of different indicators of stability and estimation methods. 相似文献

More so than previously, in recent years tourists have been exposed to unexpected adverse situations, such as political instability, caused by the destination. Many aspects of the destination experience do not involve service delivery and product consumption; thus, such an experience needs to be treated uniquely. Acknowledging that the effects of tourists’ inner psychological processes in this context are crucial, this study applies attribution theory to examine how tourists make sense of negative incidents caused by the destination’s natural incidents. The results show the crucial effects of globality attribution in predicting the levels of satisfaction. 相似文献

This article explores whether adding the goal of financial stability to the more traditional goals of output and price stability could improve optimality of monetary policy. A Dynamic Stochastic General Equilibrium model that endogenously incorporates financial frictions is used to derive optimality conditions across rule-based and discretionary monetary policy environments. The results indicate that it is optimal for the Central Bank to keep output below the potential level in the short term so as to dampen the inflationary effects arising from supply and financial shocks. When the economy is exposed to a financial shock, both leverage and credit spread rise significantly, thereby tipping the economy into a financial crisis and raising the probability of macroeconomic risk. 相似文献

One‐sample and multi‐sample tests on the concentration parameter of Fisher‐von Mises‐Langevin distributions on (hyper‐)spheres have been well studied in the literature. However, only little is known about their behaviour under local alternatives, which is due to complications inherent to the curved nature of the parameter space. The aim of the present paper therefore consists in filling that gap by having recourse to the Le Cam methodology, which has recently been adapted from the linear to the spherical setup. We obtain explicit expressions of the powers for the most efficient one‐ and multi‐sample tests. As a nice by‐product, we are also able to write down the powers (against local Fisher‐von Mises‐Langevin alternatives) of the celebrated Rayleigh test of uniformity. A Monte Carlo simulation study confirms our theoretical findings and shows the empirical powers of the above‐mentioned procedures. 相似文献

This article presents an analysis of the literature on systemic financial risk. To that end, we analyze and classify 266 articles that were published no later than September 2016 in the databases Scopus and Web of Knowledge; these articles were identified using the keywords “systemic risk”, “financial stability”, “financial”, “measure”, “indicator”, and “index”. They were evaluated based on 10 categories, namely, type of study, type of approach, object of study, method, spatial scope, temporal scope, context, focus, type of data used, and results. The analysis and classification of this literature made it possible to identify the remaining gaps in the literature on systemic risk; this contributes to a future research agenda on the topic. Moreover, the most influential articles in this field of research and the articles that compose the mainstream research on systemic financial risk were identified. 相似文献
