债权治理初探

负债不仅是企业融通资金的一种方式,还具有公司治理功能。不同种类、期限、优先权的负债,其公司治理效率是不同的。债权治理是指企业债权人作为公司治理主体之一对企业实施的治理。债权治理的方式主要有合同治理、流动性治理和控制权治理等。为了改善和提高我国公司治理效率,实现债权治理,应当建立有效的破产机制、推进国有商业银行的公司化改革、大力发展公司债券市场以及优化企业负债结构,创新负债融资工具等。     

对城市生活垃圾回收的质疑与思考

随着工业化和城市化的快速发展,城市生活垃圾问题作为影响城市可持续发展的重要制约因素日趋突出。大多数国家和地区都把垃圾回收作为减轻垃圾处理负担及保护自然资源和环境的有效模式而大力推广。但国内外大量的实证研究发现,垃圾回收是一种成本高昂的垃圾治理模式,不具有成本有效性。垃圾治理应从源头上减少垃圾的数量和提高产品的重复使用率,政府应减少强制性的垃圾回收,而将政策转向征收适度的垃圾填埋税(费)。

The efficiency of mutual fund companies: Evidence from an innovative network SBM approach

This paper is the first DEA (Data Envelopment Analysis) evaluation of the efficiency of a sample of mutual fund companies in a large Euro fund industry, i.e. Spain. Our novel network model links the efficiency of the core activities (portfolio management and marketing/distribution) of a mutual fund company to the efficiency of its operational management function. Our results highlight the important networking effects at the marketing stage and question the prime role of portfolio management skills in the overall efficiency of a mutual fund company. The evaluation of robust efficiency clusters indicates that the efficiency rankings obtained with our network model persist significantly along our sample period. Finally, the application of the SBM (Slacks-Based Measure) Variation III to our network model allows us to identify a large number of globally inefficient but locally efficient companies with reference to competitors with similar management resources.     

An upper bound on the minimal total cost of the transportation problem with varying demands and supplies

In general cases, to find the exact upper bound on the minimal total cost of the transportation problem with varying demands and supplies is an NP-hard problem. In literature, there are only two approaches with several shortcomings to solve the problem. In this paper, the problem is formulated as a bi-level programming model, and proven to be solvable in a polynomial time if the sum of the lower bounds for all the supplies is no less than the sum of the upper bounds for all the demands; and a heuristic algorithm named TPVDS-A based on genetic algorithm is developed as an efficient and robust solution method of the model. Computational experiments on benchmark and new randomly generated instances show that the TPVDS-A algorithm outperforms the two existing approaches.     

Coordinating contracts for a financially constrained supply chain

We consider a financially constrained supply chain in which a supplier (leader) sells products to a retailer (follower) who has no access to bank financing due to her low credit rating. However, the supplier can borrow from a bank and offer trade credit to the retailer to alleviate her financial constraint. Failure to pay off a bank loan or trade credit incurs a variable default cost. We analyze the centralized version of the supply chain to obtain new coordination requirements. We then examine whether revenue-sharing, buyback, and all-unit quantity discount contracts can coordinate our supply chain. We show that the all-unit quantity discount contract fails to coordinate. However, the revenue-sharing and buyback contracts can coordinate the supply chain, but only when the supply chain has a sufficient total working capital. Moreover, they cannot allocate profit flexibly unless the supplier has a large enough working capital. Finally, we design a generalized revenue-sharing contract that coordinates the supply chain with flexible profit allocation, and also show by numerical examples its superiority over the revenue-sharing and buyback contracts.     

股权集中度与会计信息质量相关性的实证研究

构建了一个会计信息质量综合指数,利用股权分置改革后的样本数据,采用多元回归分析法对我国上市公司股权集中度与会计信息质量的相关性进行了实证研究。研究结果表明,当前我国上市公司中的股权集中度与会计信息质量是正相关的,上市公司的最终控制人性质与会计信息质量没有关系。     

会计寻租的后果

公允价值应用研究

我国在2006年新的企业会计准则体系中全面引入了公允价值,这将对会计信息的生成和呈报产生重要影响。论文阐述了公允价值的内涵,分析了公允价值的特征,从公允价值计量的可操作性、公允价值计量的信息质量的可靠性、我国的宏观经济环境、会计人员素质等方面分析了公允价值在应用中存在的问题,最后提出了在我国推行公允价值的建议。
