城区特征通过多种途径影响商业银行住房抵押贷款决策.商业银行可以根据城区特征判断一个城区的住房抵押贷款违约风险,进而确定对该城区的最低首付款比例或拒贷率.通过分析国外城区特征对商业银行住房抵押贷款决策的影响机制,联系我国实际情况,指出我国商业银行根据城区特征进行住房抵押贷款决策具有合理性,建议商业银行密切关注城区住房价格波动率,并建议政府限制中低收入城区商业银行的数量. 相似文献

双寡头市场价格博弈分析——以我国国内成品油市场竞争主体为例 总被引:2,自引:0,他引:2
用博弈论分析市场行为是经济学的发展方向之一,本文从实证分析国内成品油市场中国石化与中国石油两大寡头的多种博弈情形及其收益变化过程,论证了在市场需求总量基本恒定状态下,双寡头市场价格博弈的纳什均衡解为(降价、降价),(不降价、不降价),前一种均衡解是双方在势均力敌、信息反馈充分的恶性竞争结果,后一种是在满足一定收益前提下的“双赢”策略。企业只有选择有别于竞争对手的非价格歧异性策略,形成自己的特色和优势,才能占领相应的市场,获得相应的经济效益。 相似文献

Armando José Garcia Pires 《Spanish Economic Review》2006,8(2):83-112
This paper estimates Krugman’s (J Polit Econ 99:413–499, 1991) economic geography model using data from the Spanish NUTS 3 regions. The econometric formalization endogenously determines wages in a region as a function of income and wages in other regions. The specification adopted also allows us to study the relation between the agglomeration of economic activity, increasing returns and market access. The first result obtained is that the Spanish economy exhibits a spatial wage structure: wages in a region are positively determined by income and wages in neighboring regions. In second place it is found support for the structural relations of the underlying theoretical model, indicating the importance of scale economies and transport costs in shaping the Spanish economic geography. 相似文献

The objective of this study is to estimate willingness to pay (WTP) for the reduction of mortality risks caused by fossil
fuel (natural gas, coal and oil) versus nuclear electric power generation systems and to examine the influence of risk characteristics
involved with electric power generation on WTP. A choice experiment was conducted to achieve these objectives. The attributes
for nuclear risks in the experiment included the probability of disasters and the expected losses if a disaster occurs. We
find evidence of (i) a baseline effect (where WTP is sensitive to hypothetical versus actual baseline expected mortality);
(ii) a ‘labeling effect,’ where, surprisingly, the term ‘nuclear’ has no effect on WTP, but the term ‘fossil-fueled power
generation’ results in lower WTP; and (iii) disaster aversion, meaning that people focus on the conditional loss from a nuclear
disaster, not the probability. We also find that the WTP for reducing deaths from a nuclear disaster is about 60 times the
WTP for routine reducing fossil-fuel generation-related deaths. 相似文献

Learning by doing,spillovers and shakeouts 总被引:1,自引:0,他引:1

This paper studies industry evolution driven by non strategic learning by doing and spillovers. We characterize a dynamic process of cost and output changes and its effect on welfare and industry profits. The paper gives conditions for shakeouts to occur and analyzes the key factors affecting these conditions. Since shakeouts could lead to a long-run social loss due to higher market concentration, there is a role for a government to play in limiting unnecessary shakeouts. The most effective way to do so is to enhance spillovers.JEL Classification:

经济体制改革的理论基础不仅仅是社会主义市场经济理论,生态经济理论也是其中之一,这是由生态经济理论原则及特点所决定了的。同时,改革的目标是建立社会主义市场经济体制,在新体制的建立过程中,也必须注意实现生态经济协调的几个问题。 相似文献

Government as a discriminating monopolist in the financial market: the case of China 总被引:2,自引:0,他引:2
Roger H. GordonWei Li 《Journal of public economics》2003,87(2):283-312
We show that the many unusual features of China’s financial markets are consistent with a government choosing regulations to maximize a standard type of social welfare function. Under certain conditions, these regulations are equivalent to imposing explicit taxes on business and interest income, yet should be much easier to enforce. The observed implicit tax rates are broadly in line with those observed in other countries. The theory also forecasts, however, that China will face increasing incentives over time to shift to explicit taxes. 相似文献
