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.     

VIX term structure and VIX futures pricing with realized volatility

Using an extended LHARG model proposed by Majewski et al. (2015, J Econ, 187, 521–531), we derive the closed-form pricing formulas for both the Chicago Board Options Exchange VIX term structure and VIX futures with different maturities. Our empirical results suggest that the quarterly and yearly components of lagged realized volatility should be added into the model to capture the long-term volatility dynamics. By using the realized volatility based on high-frequency data, the proposed model provides superior pricing performance compared with the classic Heston–Nandi GARCH model under a variance-dependent pricing kernel, both in-sample and out-of-sample. The improvement is more pronounced during high volatility periods.     

金正恩时代的朝鲜经济体制转型研究

采用转型政治经济学的理论框架,分析金正恩时代的经济改革可以发现,朝鲜在经济战略、价格、市场、产权和经营权、对外经济、金融、财税等领域采取了一系列改革措施,日益呈现出计划经济向市场经济过渡的转型特征。金正恩的经济改革不是经济管理方式的浅层变化,而是经济体制的转型。朝鲜经济体制转型虽取得一定成果,但仍面临着国际制裁、国内制度建设滞后等约束条件,迫切需要在无核化问题上继续前进和进一步的改革。朝鲜经济体制转型有利于推动朝核问题解决和东北亚地区合作进程,各国应据此制定针对性的对朝政策。.     

黑龙江旅游网络关注度时空演变特征研究

探究黑龙江旅游网络关注度时空演变特征对黑龙江旅游业良性发展具有重要意义.利用百度指数获取2011—2018年全国和分地区黑龙江旅游网络关注度逐日搜索指数数据.从时间分布、空间分布、时空集聚3个方面研究其演变特征.研究表明:2011—2018年全国黑龙江旅游网络关注度年际变化总体呈现上升趋势,月际变化呈"W"形;2011—2018年31个省区市黑龙江旅游网络关注度空间差异较大、季节性影响显著;东部地区黑龙江旅游网络关注度偏高,西部地区黑龙江旅游网络关注度的季节差异最明显;东部地区内的黑龙江旅游网络关注度差异性最小,西部地区内差异性最大;黑龙江旅游网络关注度具有正空间自相关,部分东部、中部地区表现为高高集聚,多数西部地区表现为低低集聚.     

知识型员工双重社会网络对企业创新绩效作用机制研究

基于企业基础资源观和组织学习理论，从知识型员工个人和组织社会网络两个方面构建知识型员工双重社会网络影响企业创新绩效的理论模型，分析知识共享、组织学习及资源整合在员工双重社会网络对企业创新绩效影响机制中的作用。结果表明：知识型员工双重社会网络对科技型企业创新绩效的作用路径有3条，资源获取与整合、知识共享与学习及员工动态创新能力分别在其中发挥中介作用；在不同类型组织文化环境中，知识型员工双重社会网络对企业创新绩效的作用特征、作用重点以及作用机制存在显著差异，内部整合维度主要通过知识共享和组织学习影响企业创新绩效，外部适应维度主要通过隐性知识传播和资源整合影响企业创新绩效。     

Further Mining the Predictability of Moving Averages: Evidence from the US Stock Market

Most studies on the predictability of moving average (MA) technical analysis use the discrete (buy/sell) trading recommendations. However, it is possibly incomplete or unreliable to explore the predictability of MA by only employing its generated trading signals. To further explore the forecastability of MA, we study its measurable impact on the stock market returns by using a conventional predictive regression framework. Our empirical study on the US stock market with respect to more detailed price information finds, (i) that the proposed predictor, MADP (MA based on daily prices) shows significant predictability in‐ and out‐of‐sample, and significantly outperforms the historical average (HA) benchmark as well as the MA based on monthly prices, (ii) that the predictability of MADP centers on the short‐term lags (within the most recent 10 days) and disappears when lags are beyond 20 days, and (iii) that the economic evaluation of the portfolios based on trading strategies confirms the superior performance of MADP with short‐term lags against the benchmark even though considering transaction costs.     

超常发展再铸辉煌--上海港集装箱运输发展回顾与展望

2002年,上海港创造了一个新纪录——集装箱吞吐量完成861万TEU,比上年634万TEU增长35.8%,超越高雄港而成为排名世界第四位的集装箱港口。这一辉煌业绩标志着作为我国大陆最大的国际通航港口又向国际航运中心建设的目标迈出了一大步。上海港集装箱吞吐量的发展是超常的。近10年来,它都以年均28%的增长率攀升。1994年突破100万达到119.9万TEU,从1997年至2001年的5年里,每一年都突破一个大数,分别超越200万、300万、400万、500万和600万TEU,2002年则跃升双百万,达到861万TEU。这是上海港集装箱运输发展史上前所未有的。它超常发展的巨大…     

相对主义的价值结构

一般认为，相对主义在价值实践中必然造成价值虚无主义，实际上，相对主义处于一个未完成状态中，它目前的结构大致具有三个层次，第一个层次是各种实在性价值，第二个层次是虚化的相对主义要求，第三个层次则是相对主义的自我反思性。这个层次结构保证了价值的自由性，同时努力避免着价值的虚无。

经济快车道正伸向阿塞拜疆

在美丽的里海之滨,)域连绵的高加索南麓,有一块8.66万平方公里面积的国土,从地图上看它,酷似一只睡梦初醒的雄鹰,开始伸展翅膀,向着大海蓝天飞翔。这就是以盛产石油而文明于世的阿塞拜疆。这个处在欧亚交界地带的国家,自1991年脱离前苏联,宣布独立后,其经济一度连续下滑。从199
