金融资产财富效应的形成机理研究

本文借助消费函数理论、行为金融理论分析了金融资产财富效应的形成机理,并将金融资产财富效应的传导机制归纳为实际收入效应、预期收入效应、流动性约束效应、信心效应、托宾q效应、替代效应等六种效应。除替代效应是负的财富效应外,其它效应均为正的财富效应,而金融资产财富效应的差异性既是上述各效应综合作用的结果,也是不同国家在不同时期影响金融资产变动的因素存在差异的结果。     

投资者法律保护、股权集中度与大股东行为

在不同的法系和国家中,对投资者的法律保护存在很大的差异。作为对投资者法律保护的替代,在投资者法律保护薄弱的国家,股权结构相对集中。为了保护投资者的利益,我国应该完善对投资者的法律保护,提高执法质量和会计质量,促进股权的适度集中,限制控制股东的掠夺行为。     

Best-matching protocols for assembly in e-work networks

Assembly networks pose many challenges to the comprising businesses due to their ever-growing distributed nature. This article explores the benefits of incorporating best-matching protocols (BMP) into the principles of design for assembly (DFA) to make better use of already existing information on equipment, parts and suppliers. Best-matching protocols for cooperation requirement planning (BMP-CRP), for part matching (BMP-part) and supplier selection were developed. A case study for the matching of parts and suppliers is provided. The results of the case study corroborate the benefits in quality and costs that the best-matching protocols can yield for businesses in an assembly e-work network.     

The effect of external supply knowledge acquisition,development activities and organizational status on the supply performance of SMEs

Given the increasingly strategic role of external resources, acquiring knowledge about current suppliers and the broader supply market is an important and demanding task for the purchasing and supply management (PSM) function of a firm. Performance-improvement-oriented application of external supply knowledge present further challenges for the function. To examine this, we draw on the knowledge-based view and develop a hypothesized model in which supply knowledge acquisition drives PSM exploration and exploitation orientations which in turn mediate the organizational status of PSM function in terms of supply performance. We test the model on an SME-focused and survey-based dataset, using structural equation modelling. Our results indicate that an exploitative orientation is associated with knowledge gained from the supply base, whereas an explorative orientation is predominantly associated with supply market knowledge and less with supply base knowledge, suggesting natural pairings. The findings also show how an exploitative development orientation mediates the positive association of the PSM function's organizational status with supply performance. Driven by supply base knowledge, a status-empowered exploitative PSM orientation may suppress supply market based explorative orientation in resource-scarce SMEs, thus appearing to serve as the sole path to supply performance. Our research contributes by pointing out the significance of the knowledge-resource, and the knowledge-based view, in understanding performance in PSM.
