Collusive Long-Run Investments Under Transmission Price-Caps

In the short run, constraints in the electricity transmission system may give market power to generators. This paper examines whether the constraints themselves are a long-run equilibrium outcome in a competitive environment. We show that independent transmission companies and generators can tacitly collude to raise prices to consumers and divide the resulting profits. We also show that price cap regulation does not prevent this behavior and may in fact contribute to it. The mechanism for collusion is that generators locate their plants so that a capacity-constrained transmission line lies between them and their consumer market. We show that this constraint-based collusion can be sustained in a static game without any punishment strategies.     

Interbank Relationships and the Credit Channel in Germany

A crucial condition for the existence of a credit channel through bank loansis that monetary policy should be able to change bank loan supply. This papercontributes to the discussion on this issue by presenting empirical evidence fromdynamic panel estimations based on a dataset that comprises individual balancesheet information on all German banks. It shows that the average bank reduces itslending more sharply in reaction to a restrictive monetary policy measure the lowerits ratio of short-term interbank deposits to total assets. A dependence on its size canonly be found if explicitly controlled for this dominating effect. Overall, the evidenceis compatible with the existence of a credit channel but the results indicate that it is weakened by the network structures that exist in the German banking system.     

信用的生态学诠释与信用生态链的构建

生态学有逐渐与经济学相渗透、相融合的趋势，从而扩展了经济学的研究边界。本文从生态学的视角对信用加以研究，首先介绍了信用生态的理论内涵，其次研究了良好的社会信用生态环境的评价标准，最后对构建和谐的社会信用生态链提出了具体的对策措施。     

Expected revenue of all-pay auctions and first-price sealed-bid auctions with budget constraints

We show that all-pay auctions dominate first-price sealed-bid auctions when bidders face budget constraints. This ranking is explained by the fact that budget constraints bind less frequently in the all-pay auctions, which leads to more aggressive bidding in that format.     

我国信贷配给区域间差异及市场分化模型

由于我国不同区域间发展极不平衡,其中比较突出的是农村和城市、东南沿海和中西部地区之间,导致了我国信贷市场区域分化。信贷市场区域分化越严重,银行越会忽视部分弱势地区,而把资金集中在部分发达地区。近年来我国信贷资金这种区域集中现象越来越明显,不同区域表现出了巨大的信贷差异。文章首先通过部分相关数据和信贷调查分析了我国信贷市场的区域分化,然后建立了信贷配给的区域分化模型,分析不同区域间信贷差异以及信贷集中。最后给出了相关的结论和建议。     

Investment opportunities and cash holdings of firms: an empirical study on Korean firms

We find that the cash flow sensitivity of cash holdings of firms whose investment opportunities are lower is significantly higher by examining a panel data of 898 Korean firms for 1999–2014. The cash flow sensitivity of investment is also found to be lower in case of low investment opportunity. Both findings suggest that firms decide to hold cash in response to an increase in cash flow when they do not have a good investment opportunity. Precautionary motive because of financial constraints and uncertainty, and agency problems, however, are not associated with the cash flow sensitivity of cash holdings. These findings imply that it is necessary to develop new investment opportunities to encourage firms to spend more cash in Korea.     

基于PCA/FCM的企业信用评价研究

针对我国企业信用评价问题的特点,文章分析了企业信用评价基本原则和主要影响因素,建立了企业信用评价指标体系。企业信用评价是一类包括一系列独立变量的分类问题,将主成分分析与模糊理论引入信用评价中,构建基于PCA/FCM的企业信用评价模型,这使得模型更接近人们的思维方式、指标赋权更为客观。应用该模型及SPSS11.0、MATLAB7.0对所选企业研究显示:该模型非常有效和实用。

地方政府怎样管好农村信用社--以贵州为例

农信社交由地方政府管理是落实管理责任市场化及强调地区性的结果。我们在总结贵州试点经验基础上提出建议.改革走向纵深，要解决增资扩股目的短期化、投资股比重低等问题；发展地看待省联社制度设计缺陷；坚持政企分开原则，加强政府对经济活动的外部组织协调，搞好促生产与抗风险的制度安排，帮助农信社形成良好的发展条件。
