论我国饭店的等级划分与价格管理

在现实市场中,为了方便对酒店进行监督和管理,也为了不同层次消费者的需要,政府往往根据不同的硬件设施标准和软件服务水平对酒店进行等级划分;同时,由于我国旅游市场的外部性因素,政府又根据相应的标准对其进行一定的价格管制, 实行限价,藉此保护消费者,但是这会对消费者和经营者产生影响。

商业银行信贷风险分析及对策研究

商业银行作为经营货币的金融中介组织,自有资本占比低这一特点决定了其本身具有较强的内在风险特性,而银行贷款质量的优劣,信贷资产所面临风险的大小,对银行的经营成果乃至生存发展有着至关重要的影响。目前中国商业银行信贷风险管理中存在着一定的问题和缺陷,这使得中国的商业银行在参与国际金融市场的竞争中处于不利的地位。

研发购并的动因、决策流程与风险管理

研发购并是替代自主研发的一种形式,也是企业获得研发资源以强化竞争优势的重要战略手段。企业在自主研发、研发购并与研发联盟之间存在一定的偏好,但是受一些环境因素的影响,企业可能作出与其偏好不一致的选择。购并企业应在目标筛选和组织整合两个阶段控制和化解研发购并存在的巨大风险。     

操作风险管理的相关研究:问题与争议

在当前的金融格局下,除了信用风险和市场风险外,操作风险的影响及其产生的破坏力进一步加大,因此,我们应加强操作性风险的监控和管理.有关学者和从业者在操作风险界定、度量工具和管理手段方面进行了研究.随着新协议的正式公布和逐步实施,以及我国银行业对外开放步伐的不断加快,新业务的不断推出,我国商业银行面临的操作风险压力越来越大,只有及早转变风险管理理念,积极引入操作风险管理,尽快建立一个有效的操作风险管理体系,才能保持我国金融体系的安全、稳健发展.     

Another strategy to assess sustainable development

The goal of sustainoble development is to preserve sustainabitity trod simultaneously prevent catastrophe in a man-land .system. However, almost all the existing approaches to assessing sustainable development are to measure the sustainability. namely appraise from the obverse side of the sustainable development. So it seems necessary to attack the same task on the reverse, namely to measure the passibility of eatostrophe. In this paper, with a case study of Tianjin, China. we employ catastrophe theory and models to integrate Tianjin＇s sustainable development indicators, and then deduce the catastrophe risk index （ CRI） to present the level of catastrophic possibility in the city. Applying catastrophe theory, is a new strategy to assess sustainable development and shows great practical significance, especially for those developing regions or countries, who always give more priority to their economy and therefore have more obligation to make sure whether their social economic activities might bring forth any ecological environment catastrophe. Besides, being both qualitative and quantitative, the approach could be employed to explore not only static characteristics bat also dynamic mechanism of man-land system. Although our work is only a maiden attempt and still calls for further effort to improve it, the case study of Tianjin in this paper would assure as the great promising future to apply, catastrophe theory to sustoinable devetopment modeling,     

Financial risk taking in the presence of correlated non-financial background risk

This paper characterizes the stochastic deterioration resulting from taking a zero-mean financial risk in the presence of correlated non-financial background risk. We show in particular that it has an equivalent stochastic order as well as a necessary and sufficient “integral condition” that implies and is implied by a particular sense in which the stochastic deterioration can be decomposed into a “correlation increase” and a “marginal risk increase”. We further characterize a measure of aversion to the stochastic deterioration. These characterizations provide for a more general framework for formulating concepts of increases in risk and correlation and for better understanding risk management decisions governed by individuals’ attitudes to them.     

Cooperative game with nondeterministic returns

We study a non-traditional cooperative game where returns from coalitions are nondeterministic. The long-standing concept of core can be generalized to reflect players’ contentment with their allocations. It is now imperative to formalize the restrictions, such as those pertaining to information, on allocations. The latter are also at times more conducive to fractional representations. With probabilistic structures added, nondeterministic returns become random variables, utility functions attain risk-attitude connotations, and the timing of players’ allocation resolutions gains significance. Under various conditions for utility functions, we show how various core concepts of the general game can be related to its traditionally defined auxiliaries. These developments help pave the way for our illustrations, within two distinct settings, that players’ increased risk aversion would promote the formation of the grand coalition.
