短期事件对旅游的影响:以中国SARS危机为例 总被引:13,自引:0,他引:13
通过回顾近年来世界各国发生的短期危机对旅游产生的影响,重点分析2003年的SARS疫情给中国经济特别是旅游业造成的重大损失,讨论了不同的短期危机对旅游的不同影响以及旅游在危机后的不同恢复时间。旅游业对短期危机缺乏足够的防御能力,但通常能较为迅速的走上复苏之路。在这个过程中,适当的危机管理措施和有效的恢复策略是十分重要和不可或缺的。 相似文献

Sustainability has emerged as an important industrial strategic outlook expanding beyond organizational boundaries to include the supply chain. Simultaneously, the industry has also been faced with supply chain resilience concerns. Research on the intersection of supply chain sustainability and resilience is nascent and is a consequence of their observed mutual influences. However, confusion about concepts, implementation methods, and measurements of sustainable and resilient supply chains remains. This study completes a systematic literature review that critically examines several major observations and directions. We find the concept of sustainable supply chains is more established, and general agreement on its theoretical foundations exists. Supply chain resilience is relatively less mature. The nexus and relationships between the two topics are often incoherent: there is confusion on sustainable and resilient supply chains establishment; there is no clarity on what practices could jointly advance both areas. A major conflict exists since sustainability generally focuses on efficiency, while resilience seeks effectiveness. We recommend studies to analyze implementation relationships and impact. We also observe that performance measurement systems should be developed to assess supply chain sustainability and resilience performance taking with explicit consideration time horizons considered in these measures. 相似文献

We build on our earlier model of money in which bank liabilities circulate as a medium of exchange. We investigate optimal bank behavior and the resulting provision of liquidity under a range of central bank regulations. In our model, banks issue inside money under fractional reserves, facing the possibility of excess redemptions. Banks consider the float resulting from money creation and make reserve‐management decisions that affect aggregate liquidity conditions. Numerical examples demonstrate positive bank failure rates when returns to banking are low. Central bank interventions may improve banks' returns and welfare through a reduction in bank failure. 相似文献

AbstractThis paper contributes to the empirical research around the “wage-led” or “profit-led” demand regimes. It first reviews how Kalecki, and then Steindl, approached the relationship between economic growth and income distribution. Then, empirical analysis carried out under the probabilistic approach to econometric modeling shows statistical evidence, estimated through cointegration analysis, that in the long run, in three very open economies—Mexico, France, and Korea—the wage share is positively associated with demand and output. It finally discusses the macroeconomic dilemma that almost all countries have to face, i.e., a positive effect of a high-wage policy on demand and employment may diverge from a negative effect on output compatible with external equilibrium. 相似文献

Conclusion Trade with the Soviet Union represents only a small part of total Community trade (3.5 % of EC imports and 2.7 % of EC exports in 1990). EC imports from the Soviet Union increased moderately between 1989 and 1990 as well as between the first six months of 1990 and the corresponding period of 1991, whilst EC exports decreased sharply as a result of hard currency shortage in the Soviet Union.The CMEA and Soviet disintegration processes will lead to a substantial reorientation of trade flows. This development has already begun with large increases of trade between the EC and the Central and Eastern European countries.International assistance to the USSR mainly consists of export credits. Community assistance involves a large proportion of grants and technical assistance. The cost of assistance measures envisaged so far remains limited for Western countries.The economic effects of assistance would be enhanced if effective coordination was implemented among the providers. Adequate mechanisms such as triangular operations or the untying of assistance would be required in order to avoid crowding out traditional suppliers from Soviet markets. 相似文献

Conventional wisdom holds that when a firm gets into trouble due to lagging sales and rising costs, cutting the size of the organization to reduce fat and waste is a normal and effective response. In this study, evidence was found to suggest that just the opposite might be true. The financial performance of Fortune 100 companies was tracked over a five-year period—two years prior to the announced layoff, the year of the layoff announcement, and two years following it. Contrary to expectations, the results indicate that financial performance worsened, rather than improved, following announced layoffs. Strategic and human resource implications for the management of corporate downsizing are provided. 相似文献

Risk and Capital Structure in the Regulated Firm 总被引:1,自引:0,他引:1
This paper studies the role of capital structure in a regulated firm. We show that it affects the prices set by the regulator, the expected price being lower the higher the proportion of debt finance. However, when debt is increased beyond a certain level, the benefit of lower expected prices is offset by their increased variability. We also study the socially preferred capital structure. This is such that consumers carry some risk, in the form of higher prices in adverse economic conditions. 相似文献
