Ready to run: price determinants of thoroughbreds from 2 year olds in training sales

This article utilizes data from the complete set of U.S. thoroughbred 2-year-old in-training sales held in 2013 and estimates the determinants of prices for 1806 two-year-old thoroughbreds. The results reveal that the time in which these prospective racehorses run a standardized distance is the most statistically significant determinant of market price. Other individual horse characteristics, pedigree quality variables and sale quality are also found to be price determinants. An additional result of interest is the significant premium buyers are willing to pay for horses by sires of unknown quality.     

中国P2P网贷停业及问题平台研究——基于网贷之家数据的实证分析

借助网贷之家的相关数据,本文对中国停业及问题网贷平台进行了实证分析。结果表明,2011年~2016年,中国停业及问题网贷平台数量快速增长;在问题平台的事件类型方面,2011年~2016年,提现困难、经侦介入、停业和跑路四种事件类型在不同时期的重要性并不相同;在问题平台的区域分布方面,2011年~2016年,总体上东部地区所占的比重最高,中部次之,西部最低。     

中国东、中、西地区碳排放空间差异测度及成因研究

碳排放空间差异测度研究对于科学合理地制定我国节能减排政策具有一定的指导意义。本文采用总离差和平均差测度了中国东部、中部和西部三大地区人均碳排放的空间差异,然后基于地区分解和kaya恒等式的总离差因素分解模型分析了差异的来源和成因。研究发现,2000年以来,三大地区人均碳排放量空间差异呈扩大态势,碳排放差异主要来源于地区内部,主要成因是人均GDP ,其次是能源强度和能源结构,其中西部人均GDP的贡献率初期较小但增长迅速。本文研究结论表明,在推进节能减排进程中,除了要优化能源结构和提高能源利用效率外,针对不同地区应制定不同的节能减排政策,体现节能减排政策的差异化。     

2型糖尿病患者血浆同型半胱氨酸水平的研究

目的：探讨2型糖尿病与血浆同型半胱氨酸（Hcy）的关系。方法纳入176例2型糖尿病（T2DM）患者和100例健康体检者。分别测定空腹血糖（FPG）、血浆同型半胱氨酸（Hcy）、糖化血红蛋白（HbAlc）、果糖胺（GSP）的含量。比较T2DM和健康对照组Hey水平及其他重要生化指标的差异。结果T2DM患者Hcy水平显著升高较健康对照组差异有统计学意义。结论血浆同型半胱氨酸（Hey）升高可加重2型糖尿病（T2DM）的代谢紊乱及叶酸、维生素B6、维生素B12缺乏。     

P2P业务中的金融消费权益保护问题研究

近年来我国P2P网贷行业快速发展,但随着一批P2P公司陷入兑付困境,其背后隐藏的风险也开始显现。本文在介绍P2P存在的管理不规范等问题的基础上,剖析了导致这些问题的根源——立法空白、监管缺失、自律不足,最后提出了明确监管法规和部门、建立平台资金管理机制、加强信息披露等建议。     

What Are SEC Football Tickets Worth? Evidence from Secondary Market Transactions

Tickets to sporting events are highly differentiated—seat location, date and time of the game, and home‐team and opponent qualities make each ticket unique. Preferences also differ nontrivially across fans, all of which make the supplier's pricing problem complex. We examine strategies employed by Southeastern Conference (SEC) universities in pricing their football tickets and evaluate their effectiveness in extracting surplus from fans. We use hedonic analysis of data collected from online secondary market transactions to construct a synthetic season ticket, which we compare to prices actually charged by university athletic departments. We also compare quality premiums charged by universities for better seats with market evaluations of those quality differences.     

双系统决策的实验证明与决策优化

双系统决策是建立在人们的情感、理念和经验基础上的思维活动,即系统1和系统2两个子系统代表了直觉和理性两种具有不同认知功能的思维模式.本文利用实验经济学的方法分别探究了系统1和系统2判断决策时的不同特点,以及在两个系统的相互影响下对人们决策的影响.针对双系统决策的特点,围绕公共物品实验对双系统如何优化决策提出了建议.最后针对系统1和系统2可以相互影响决策行为的猜想,介绍了山东大学经济研究院所做的一个实验研究.     

Should tweets differ for B2B and B2C? An analysis of Fortune 500 companies' Twitter communications

Business-to-business (B2B) marketers hesitate to embrace social media as a marketing tool, unlike their business-to-consumer (B2C) counterparts, and they struggle to implement successful social media strategies due to their limited understanding of the phenomenon. Drawing on communication and word-of-mouth theories, the authors investigate how marketers use Twitter differently across contexts and predict key factors likely to influence the message strategies used in each. A longitudinal content analysis and logistic regression support the assessment of a sample of more than 7000 tweets by Fortune 500 companies. Marketers in B2B and B2C settings exhibit significant differences in their branding and selling strategies; their use of message appeals; and the use of cues, links, and hashtags to support information searches. Whereas B2B marketers tend to use more emotional than functional appeals in their tweets, neither B2C nor B2B marketers have adopted “hard sell” message strategies.
