Psychological test sales and internet auctions: Ethical considerations for dealing with obsolete or unwanted test materials.

Psychological test publishers have longstanding policies prohibiting the sale of psychological tests to unqualified persons. Psychologists are also ethically bound to maintain test security. The emergence of Internet auction sites, however, poses a heretofore unrecognized threat to test security. This 3-month survey of auction listings on eBay found that both personality and intelligence tests, including test manuals, are available, and that sales to unqualified persons are not always restricted. These findings highlight a need to strengthen the ethics code to specify standards for the disposal of unwanted test material. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Bid-Spread

Analysis of the difference between the lowest and second lowest bids, or bid-spread, in a “lowest wins” auction is of possible value in strategic bidding, providing an indication of mistakes in bids, determining a justifiable amount of bid security, and a means of providing some insight into the consequences of nontraditional auction arrangements. Bid-spread analysis, as developed in this paper, provides some explanations concerning the nature of bids and their statistical properties. In particular, it is shown here that, through the analysis of several data sets originating in various parts of the world, the percentage bid-spread is consistent with the assumption that bids are entirely random, being drawn from a lognormal distribution.     

Modeling the Residual Market Value of Construction Equipment under Changed Economic Conditions

This paper reapplies a statistical model that was created prior to 2003 to forecast the residual value of used heavy construction equipment in the United States. The objective is to evaluate the performance of the model in the radically changed economy in the second half of the decade. The research hypothesis addresses whether the model is still usable and functional even almost a decade after the data occurred that determined its coefficients. This existing statistical model was a comprehensive multiple linear regression analysis for various categories of common types and sizes of equipment. Manufacturer, condition rating, and auction region are included as binary indicator variables. Statistically significant macroeconomic indicators can be used directly, but they provide new challenges as various governmental data series have been discontinued or modified, so that valid replacements must be found that range until the time of the economic crisis. Performing such a reanalysis faces technical challenges, including that several macroeconomic data series since the time of the original study have been discontinued or modified by their governmental sources. Moreover, new auction sales records mostly lack conditions and are devoid of locations. Various reconstructions are explored to still enable a valid reanalysis and, on validation, are used to augment the previous data series seamlessly with new data. Expert elicitation is used to select several equipment types that are likely to be affected by the recent economic downturn. The existing implementation tool is provided with the updated data for calculating forecasted residual values that are compared statistically with actual auction sales prices. Both practical and numerical problems are identified. The model consistently underestimates the actual values, indicating that they are less affected by the economic crisis or new variability is introduced from reconstructing its inputs. It is recommended that such model should be regularly updated, ideally by a professional organization.     

对湖南省探矿权出让制度的探讨

湖南省探矿权出让制度将国家探矿权出让政策规定的“申请在先”方式出让的探矿权一并纳入了招拍挂范围，按照评估价1．5倍收取地勘单位有偿处置探矿权价款。这些做法有积极的一面但不利于地质勘查市场更好地发展。湖南省探矿权出让制度应与国家探矿权出让制度保持一致，并建立健全协议出让探矿权制度、地勘单位价款转增资本金制度、合理完善价款评估制度等等。

Statistical Considerations for Predicting Residual Value of Heavy Equipment

Residual value needs to be considered in owning cost calculations for used heavy construction equipment. Its dependency on factors such as manufacturer and model, equipment age, and condition rating can best be examined by analyzing real market data from equipment auctions. Macroeconomic indicators can also be included to examine any potential influence of the overall economy on auction prices. This paper discusses statistical considerations for performing such a residual value analysis. Considerations include the study type, data properties, identifying outlier observations, regression assumptions, and formulating and selecting an appropriate regression model using the adjusted coefficient of determination. A second-order polynomial of equipment age with additive factors appears promising as the final regression model. Adjusted confidence and prediction intervals are created to correctly display residual value. Cross-validation using randomly split halves of the dataset is performed. Actual data for medium track dozers are used to illustrate the validity of the methodology.     

Reverse Auctions: Controversial Bidding Practice

Although reverse auctions have been utilized in the procurement of goods for many years, the availability and widespread use of the Internet has recently lead to a dramatic increase in its employment. Reverse auctions have recently found their way to a new market: procurement of construction services. As business and commerce have moved toward e-business and e-commerce, construction is drawn into such new practices. There is an ongoing debate as to whether reverse auctions are suitable equally for the procurement of both goods and services. Some contractors are concerned that reverse auctions are just another form of bid shopping. It is necessary for the construction industry to understand and evaluate the pros and cons of reverse auctions. This article discusses the procedures involved in conducting online reverse auctions and describes reverse auction practices, their advantages, and disadvantages. It also examines the legal principles of reverse auctions, potential problems, and challenges to its use.     

Bidding on the future: Evidence against normative discounting of delayed rewards.

Normative economic models assume that delay-discounting rates for future rewards are independent of the amount of, and delay to, a reward. These assumptions were tested in 3 experiments in which participants were asked to bid their own money on delayed monetary rewards in a sealed, second-bid auction. In Experiments 1 and 2, participants made their bids without feedback about the bids of other participants. In Experiment 3, half of the participants received such feedback. In Experiments 2 and 3, participants adjusted their bids until they were indifferent between the bid and the delayed reward. Participants' bids violated both normative assumptions: Discounting rates decreased with increases in amount for 62 of 67 participants, and a function in which the rate decreases with increases in delay (hyperbolic) fit the bids better than did a normative function (exponential) for 59 of 67 participants.

基于资源禀赋差异的稀土资源税改革效应及方向研究

2011年以来我国进行了2次稀土资源税改革，旨在完善稀土资源税制，调节级差收益，推动稀土合理定价机制的形成，促进稀土行业持续、健康、稳定发展.文中基于资源禀赋差异视角对比分析2010—2017年南、北稀土企业改革前后税负水平及改革效应，研究发现调节级差收益以及稳定企业税负的改革目标初步实现，但仍然无法准确反映资源价值差异及其变化，没有对构建稀土合理的定价机制起到明显的作用.文中建议稀土资源税的未来改革需统筹考虑稀土资源的特殊性和稀土行业发展的特殊背景，借助市场化的“资源拍卖”方式来实现稀土资源税的资源保护和价值体现的目标.
