Hedonic pricing and the role of stud fees in the market for thoroughbred yearlings in Australia

Using data from one of Australia's largest thoroughbred auction houses, we investigate the price determinants of thoroughbred yearlings sold at auction. We include novel key variables to construct hedonic pricing models and examine the relative role of stud fees compared to the wide range of attributes in the pricing of yearlings. We find that the price effect of stud fees is influenced by the value buyers place on both the characteristics of sires and the characteristics of sire side siblings. The findings imply that the quality of dams a sire has been matched within the breeding market has consequential effects on yearling prices through the sire's stud fee and progeny.     

Methodological Advances in DEA: A survey and an application for the Dutch electricity sector

We survey the methodological advances in DEA over the last 25 years and discuss the necessary conditions for a sound empirical application. We hope this survey will contribute to the further dissemination of DEA, the knowledge of its relative strengths and weaknesses, and the tools currently available for exploiting its full potential. Our main points are illustrated by the case of the DEA study used by the regulatory office of the Dutch electricity sector (Dienst Toezicht Elektriciteitswet; Dte) for setting price caps.     

用弦线模量法计算地基沉降和黄土湿陷变形

用弦线模量法^[1]设计黄土地基，从计算地基沉降和湿陷变形出发，概念清楚，方法简单，用地基的物理指标得出弦线模量，可省去做压缩实验。     

Market Failures in Real-Time Metering

Policies to promote real-time metering (RTM) require more than showing benefits from more timely responses to variations in cost. They require positive externalities to imply that too few meters would be installed through private transactions. RTM presents no systematic externalities when utilities must serve peak period users, and may present negative externalities under some conditions. Positive externalities are likely when electricity is rationed through blackouts. RTM may or may not increase welfare when peak period wholesale markets are not competitive; a prohibition on RTM might be appropriate in such situations even if metering itself were costless.

城市人居环境定级方法研究

对我国开展的人居环境评价研究进行了回顾,提出对城市内部人居环境进行定级的思想:将人居环境进行评级,体现人居环境空间差异,让人居环境级别落实到具体的街道和小区,从基层做好人居环境建设工作.对人居环境定级方法进行了探索,提出城市人居环境定级原则,然后根据城市特点建立城市人居环境定级指标体系及权重.在此基础上,经过因素分值计算、定级单元划分、单元因素分值及其总分值计算对人居环境进行初步定级.最后通过意见征询和实地校核,确定最终定级结果.     

Regulating an Externality-Generating Utility Environmental Taxes Under Limited Information

Global warming is currently an important item on most nationalenvironmental agendas. In many countries, coal-fired electricity generatingstations represent an important source of greenhouse gases. We examinehow regulations to curb emissions affect public utility pricing regulationwhen regulators act non-cooperatively. We show that, when there is limitedinformation on fixed abatement costs, an environmental regulator prefersan emission tax over an output tax or a lump sum environmental tax. Thepublic utility regulator prefers the lump sum tax regime.

“中国丹霞”福建泰宁世界自然遗产地社区居民点发展模式评价模型研究

为科学优选自然保护地社区居民点发展模式，构建客观评价模型对社区居民点发展模式进行定量评价显得尤为重要。基于“中国丹霞”福建泰宁世界自然遗产地9个社区居民点的调研数据，采用序关系分析法，以居民点人口结构、居民点景观风貌与传统文化、居民点产业发展模式，以及居民点位于遗产地的位置4个一级指标和相应二级指标为评价准则，构建该遗产地社区居民点发展模式优劣评价模型。研究表明，该遗产地9个社区居民点发展模式中，4个为疏解型，3个为搬迁型，2个为控制型，没有发展型。研究结果可为该遗产地社区居民点科学遴选发展模式提供定量评价依据，也可为生态价值高的自然保护地社区居民点发展模式的遴选提供参考。
