Measuring oligopsony power

An empirical test of oligopsony power is developed, where the conjectural and supply elasticities are estimated simultaneously. A Generalized Leontief profit function is used to represent the production structure. The test is applied to the Swedish pulpwood market. Support is found for the hypothesis that the degree of market power varies over time.We acknowledge a research grant from the Swedish Council for Forest and Agricultural research.     

基于地区功率平衡的新能源最大接纳能力评估

新能源出力具有的随机波动性特点,使其不能像常规电源一样输出稳定可控的功率。大规模新能源并网必然会对电力系统的安全稳定运行带来挑战。随着新能源装机容量的快速增长,为了使新能源的建设速度与电网建设及负荷发展相适应,减少弃风弃光现象,对当前阶段的新能源接纳水平做出准确的评估显得尤为重要。以某省份实际运行情况为例,考虑了调峰、网架输送能力等制约新能源接纳能力的主要因素,提出了一种基于省内各地区功率平衡的最大新能源接纳能力评估方法,为各地区新能源的装机规模与建设时序提供参考。

并联电容无功补偿对电网电气参数的影响

根据"十一五"规划,在整个"十一五"期间单位GDP能耗要下降20%左右。这一规划目标在全社会掀起了大力提倡降耗节能的高潮。电力企业一直重视降耗节能,其中并联电容无功补偿是电力企业节能降耗的主要措施之一。目前关于并联电容的研究大都集中在优化的目标和手段上面,而忽略了电容器的投入对电网中其他节点电气参数的影响方面的探讨和分析。通过实例分析,说明了并联电容器的投切对整个网络的电气参数都有影响,即并联电容器的投入不仅对补偿节点的电压和无功注入产生了影响,而且对电网中节点间的支路功率损耗产生影响,同时也对电网元件对地支路的功率损耗产生影响。

Market power and unemployment

This paper explores the under-consumptionist idea that market power can preclude the existence of a full employment equilibrium within the framework of the modern theory of economic growth. It is shown that the introduction of market power can indeed eliminate the full employment equilibrium. In an attempt to assess the importance of this possibility maximum values for the market power parameters consistent with a full employment equilibrium existing are computed. In some plausible cases these maxima are uncomfortably low suggesting that market power has significant potential for causing unemployment.

Toward measuring monopoly power

Some implications of Hyde and Perloff's paper on whether monopoly power can be measured are considered. It is concluded that measuring monopoly power requires a long-run view, with a focus on the implications of product differentiation, and a reliance on accounting data.

Market definition,market power

Market definition and market power are central features of competition law and practice but pose serious challenges. On one hand, market definition suffers decisive logical infirmities that render it infeasible, unnecessary, and counterproductive, and the practice of stating market power requirements as market share threshold tests is incoherent as a matter of empirics and policy. On the other hand, market power is often probative of the desirability of liability, yet the typically assumed functional relationship is unexplored and often implausible. These latter deficiencies are addressed through a ground-up analysis of the channels by which market power can be relevant. It is important to explicitly and simultaneously consider both anticompetitive and procompetitive explanations for challenged practices and to attend to the magnitudes of the social consequences of correct and mistaken imposition of liability in order to identify the various ways and senses in which market power bears on optimal decision-making.     

Market power and banking failures

We investigate whether more competition in the banking industry necessarily results in a higher probability of banking failures, as it is often suggested. In our model borrowers face a moral hazard problem, which induces banks to choose between costly monitoring and credit rationing. We show that investment decreases with the lending rate and increases with monitoring effort. Since incentives to monitor are enhanced by market power, the relationship between market structure and investment is ambiguous. In the presence of non-diversifiable risk and decreasing returns to scale, more investment implies higher failure rates. As a result, the relationship between market power and banking failures is ambiguous.

Distribution performance and power sources

Performance is the primary concern of industrial channel members; yet, marketing researchers have focused their attention, not on performance, but on other aspects of channel relations: power, control, and conflict. This study investigates performance and the sources of the power-performance relationship in an industrial distribution channel.     

The power of local information

The author argues that telecommunications efforts too often tend to stress distant connections. The local informative contacts are important, and should be given a chance in future systems. The argument presented to support this view includes the specific example of the TERESE project (Telecommunications and Rural Development in Sweden). This publically funded project uses narrowband communication, including computer conferencing, to stress economic and social identity in a region in the far north of Sweden. Details of continuing regional efforts are given.
