Research and analysis on bid rigging mechanisms

This paper examines detected bid rigging mechanisms based on the decisions of the Japan Fair Trade Commission (JFTC) from April 1996 to December 2005. We first develop some indicators that represent important characteristics of the ring mechanism from a theoretical and empirical point of view. We then classify bid rigging cases filed by the JFTC based on these indicators. We also provide simple economic analysis using the JFTC database and find that (1) extremely simple mechanisms were adopted in many bid rigging cases detected in Japan during the period examined and (2) some ring mechanisms facilitate a reduction in information asymmetry among ring members, however such function plays a subordinate role.     

Great School Milk Conspiracies Revisited

This paper revisits a particular case involvingtwo dairy processing companies accused ofrigging bids in northern Kentucky schooldistricts during the 1980s. Evidence andarguments presented to support a conclusion ofovert collusion are reassessed. Analyses ofincumbency rates, market shares, bid levels, biddispersions, bid distance relationships, exactbidding differentials, and bids from hellindicate that the two dairies may have beenengaged in tacit collusion instead of overt collusion.     

一种应急救援索系统的开发应用研究

在地形、地势复杂的地区输送应急救援人员或物资面临着道路中断等情况。为了解决这类问题,依据国标规范和实地工况,提出了小型救援系统的基本设计要求和工作原理,设计了结构参数。针对该救援系统的承载索部件,阐述了其设计方法和力学计算过程,并建议采用超高分子量纤维绳替代钢丝绳的设计,以降低系统成本,提高工效,然后对该救援索系统的牵引驱动模块进行了设计计算。在湖北省某地,采用机械提升倒装法对该救援索系统进行了现场组装、调制和试验,证实了在复杂的地理条件下利用临时组装架空索道实现小型物资应急输送的可行性,为实现经济物资的远距离、快速架设索道应急输送技术开发提供了数据支持及设计试验方法,具有一定的推广应用意义。
