串通投标罪客观要件探析

针对司法实践中理解、适用串通投标罪存在的歧义,探析该罪的客观要件内容,认为该罪的成立应以存在法律意义上的招投标活动为前提,并对该罪的具体行为方式、罪与非罪的标准以及实践认定中的有关问题进行探讨。     

Identification of Standard Auction Models

This paper presents new identification results for models of first–price, second–price, ascending (English), and descending (Dutch) auctions. We consider a general specification of the latent demand and information structure, nesting both private values and common values models, and allowing correlated types as well as ex ante asymmetry. We address identification of a series of nested models and derive testable restrictions enabling discrimination between models on the basis of observed data. The simplest model—symmetric independent private values—is nonparametrically identified even if only the transaction price from each auction is observed. For richer models, identification and testable restrictions may be obtained when additional information of one or more of the following types is available: (i) the identity of the winning bidder or other bidders; (ii) one or more bids in addition to the transaction price; (iii) exogenous variation in the number of bidders; (iv) bidder–specific covariates. While many private values (PV) models are nonparametrically identified and testable with commonly available data, identification of common values (CV) models requires stringent assumptions. Nonetheless, the PV model can be tested against the CV alternative, even when neither model is identified.

Identifying non-competitive bids in construction contract auctions

Construction contract auctions are characterised by (1) anticipated high outliers due to the presence of non-competitive bids, (2) very small samples and (3) uncertainty of the appropriate underlying density function model of the bids. This paper describes the simultaneous identification of high outliers and density function by systematically identifying and removing candidate (high) outliers and examining the composite goodness-of-fit of the resulting reduced samples with the normal and lognormal density functions. Six different identification strategies are tested empirically by application, both independently and in pooled form, to several sets of auction data gathered from around the world. The results indicate the normal density to be the most appropriate model and a multiple of the auction standard deviation to be the best identification strategy.     

出口隐含碳排放的产业分布及优化对策研究

文章依据非竞争型投入产出表,在剔除进口中间投入所节省的能耗和碳排放的基础上,对2002-2011年各产业出口隐含的CO2排放量重新进行了测算。结果表明,我国出口隐含的国内碳排放量比同类文献的测算结果要低;而且,某些碳排放强度高的产业其出口隐含碳排放的占比并不高,相反,某些碳排放强度低的产业其出口隐含碳排放的占比却较高。这种反差主要是由于不同产业的出口规模不同造成的。因此,要减少出口隐含的碳排放量,不仅要鼓励节能和清洁技术的研发,降低各产业的能耗强度和碳排放强度,还应逐步压缩高耗能、高排放产业的产能和出口规模,不断优化出口结构。     

中国区域间投入产出模型研制方法研究

 本文提出了一个新的区域间贸易系数的估算模型,对中国区域间投入产出模型研制方法和具体步骤做了进一步研究和完善,并研制了2002年和2007年中国区域间投入产出模型。区域间投入产出模型的结构使其很难具备比较完整、准确的调查统计数据基础,因此决定了它的研制工作必须将调查统计数据与科学推算方法密切结合。在模型研制当中,我们结合国家统计局全国投入产出调查中反映各省间流入、流出的调查结果,和运输量统计等基础数据,采用典型调查和非调查相结合的方法;同时充分利用各省表的信息,并以全国表作为总量控制,进行平衡调整。

Market‐Based Allocation with Indivisible Bids

We study multiunit double auctions accepting bids with indivisibility constraints. Modeling the auction problem as a Multiple Choice Knapsack Problem and using dynamic programming, we show that incremental computations during bid processing can speed the handling of key auction operations such as clearing and quoting. We propose different price‐quote policies and study their influence on the efficiency of market‐based allocation. Using a reconfigurable manufacturing scenario where agents trade large quantities of multiple goods, we demonstrate potential benefits of supporting indivisibility constraints in bidding. These benefits are highly sensitive to the form of price quote provided, indicating interesting tradeoffs in communication and allocation efficiency.
